The company should be making this video their official install video. The module even fit perfectly in the fuse box and no need to zip tie anything (on A 2018 CX-5). Very well done!
👍🙃
Step 1. I watched the video. Step 2. I ordered the unit from Amazon. Step 3. Next day delivered and it took exactly 31 minutes from start to finish including reprogramming my driver side auto window as in the video.
This video explains everything I needed to know. I didn't even look at the instructions in the box.
🙂👊
@radieyevanov you saved me $400 CAD. I was quoted $650 plus tax. I know it was not the same remote starter, but I didn't need the extra fobs and 3000-foot range.
@@user-fk4nu3zz8s same here. Just needed something that was simple, affordable and worked with my kefob. I just need to start it from inside the house to heat it up before I leave in the AM
did you get the lockx3 or lock unlock lock one ?
I did mine in a mazda 3 hatchback, no issues.
Had to wrap the box at the back left corner of the dashboard, i already had some stuff in the fusebox.
Great vid , tremendously helpful and i did it jn about 30 mins.
I had a hard time unplugging the two cords, my tip with the same plastic tool press the middle lock part as you pull the connector
Thank god for people like u!!! Thank u for the video I used it during my install and it went smooth as silk! Also thank u for the bit about the windows that would have driven me crazy!! But ur tip worked like a charm! Warmer winters here I come!!!
Thank you for the kind words! 😊
thank you so much for such a helpful video. installed on my 2015 CX5. It was very precise and covered all the details perfectly, down to the Auto Window function. Thank you!
You are welcome! Thank you for the kind words!
Did the install today and yes it was the easiest one to do.. works great !
Extremely helpful. Thank you for doing this video. Here are some additional tips that may help others.
Remote Start Programming
1. Disconnect battery Negative first then install harness per video.
2. Hold reset button on module while attaching black power cable wait until module turns orange then release reset.
3. Press car Start/Stop button twice if good module will flash green and put key fob on module while programming.
4. Wait until module stops flashing then press car Start/Stop just ONCE and Programming is Complete.
To test press Lock 3x on remote.
To exit Remote Start
1. Unlock car
2. Step on brake for 3 seconds then drive.
Hope this makes it easier. Enjoy.
Welcome Random Waffles 👍
Bro! This is one of the absolute best vids I ever watched on YT!!! Thanks.
Haha why thank you kind sir!
Just bought one for my 17 mazda 6. Cant wait to get it installed this week. Thanks for sharing!
Anytime!
I know this is an older video but I just purchased a 2017 Mazda 6 for my son, how is the kit holding up after a year?
@@CoachClyde Ended up not using it
Excellent video, so helpful and gave me the confidence to try and do it myself and save at least $200 I’d pay to a shop to install it. I suggest getting the “lock unlock lock” device so it doesn’t beep when you do it.
Thank you Eugene! And yes, I agree. They didn't have that option when I bought and installed this.
Just found this video now, kind of want to buy one since winter is coming. If it’s as easy as it sounds, I’m sold lol
Haha it's as easy as it sounds! I wish all of them were this easy lol
Awesome video, I will be getting this now, couldn't be easier
Awesome video man! Just installed mine and fixed the window issue too!
Thanka man 🙂
Thank you taking the time to makes this video helped out in making my buying decision
You are welcome!
lightweight baby !! Thanks for your help 💪
Thanks! This made it so easy!
Just ordered one for my sons 2016 Mazda6. It should be here Monday.
👍
This video was SO helpful, thank you! There wasn't room for the module in the fuse area of my Mazda6, but I zip-tied it to a bundle of wires under the dash, and good to go. The only quirk so far is that once started the car doesn't want to unlock with the fob, you have to use the button on the door handle. Winter just got a little more manageable!
You know, I don't even think I ever tried unlocking it with the fob I always just use the door button lol
Great video, I just installed this remote start for my Mazda 3 hatchback, it got no issue to unlock my car with the key fob. Actually I tested, the module respond better if I lock and unlock the car with the key fob. Also, the module take control of the turning lights making them to blink once when I closed the trunk door when the car is off, this thing never happens before.
By the way, according the instructions of the manufacturer, the car will turn off 45 seconds after you unlock the car. I checked, after 45 seconds it will not shut off automatically, unless you press the brake pedal after this 45 seconds. The car will not shut off if you unlock the car, before this 45 seconds you have to press the brake pedal for the key fob can takes control
@@kcs1981 that's cool. I never tried that cuz usually I just get in and go but that's cool to know! Thank you!
I also have a Mazda 6 2021 and the key fob does unlock however the car shuts off once the brake is pressed and has to be restarted does this happen with your Mazda as well ?
Great instructional video. Most appreciated. The problem I have is my Mazda is a 2013 Grand Touring Hatch. Guess I'll have to dig around for compatible unit. Again thank you.
Thank you for the feedback Michael! Appreciate it!
Hi, brother. thank you very much for this video. Your explanation is complete and easier to understood.
Welcome sir! Thank you!
Great video one of the best! I just followed along and everything worked perfectly new sub here!
Thanks so much Erik! Appreciate the sub 👊
Lovely video! Easy to understand, and not unnecessarily lengthy. I don't have one of these vehicles, but I've been eyeballing them and wanted to know if you could get a remote start. Guess you can!
Yes you can. And thank you 😊
Cool video bro
This was superb sir I am buying one
🙃👍
Great video
Thanks 😊
used this video to install mine. better than the factory one.
👍😊
Yo!! Thank you for this video!! I decided to purchase the Start-X for my 2017 Mazda 6 because of this video and how easy it looked to install. And installed it yesterday and it was indeed easy to install. It took me longer to find a decent mounting spot for the module than to the actual installation and programming of the module. So far it has worked like a charm. I do need to find a better spot to mount it, I had zipped tied it to a cable but I have to redo that. Where would you recommend to mount it? I tried to put it in the fuse box but mine is too small for it. Whomp whomp.
Hey you are welcome Will! Honestly anywhere would do so long as it's a sturdy location. Keep it away from moving parts, pedals, etc. as well as away from vents.
This is such an awesome video to make installing this way easy. I’m trying to figure out how to disable the honking when you press the lock button, but that’s still a mystery for me to solve.
Thank you
PS Only way would be to disable power to the horn itself. The ECU is otherwise programmed to always make the horn beep when it receives a lock signal and tampering with the ECU programming may not be possible for this specific reason. Disclaimer: to my knowledge
Hi , I just bought the star x remote starter
My question is how do you connect the little black box with the cable
Thank you! Installed on 2018 cx-9. Works great and thanks for the tips. Nicely tucked in fuse box. Did you happen to hear a whining noise under the hood when ignition is turned on. I noticed since hood was open in process of installation. Not sure it’s normal for Mazda when just ignition is on because we never open the hood
Yup, noise is normal it's supposed to do that 👍😊
Awesome
Thank you for the video
It helps us a lot
Does the parking lights Illuminate when we use the remote starter to start the car to let the user knows that the Ignition is on and running? Sorta like a confirmation or feedback.
That would actually be pretty cool if it did but no sadly it doesn't
Hi, thanks for this very helpful video.
Wondering if I install this and go to remote start my vehicle, will it automatically apply the previous climate control settings? Example is hearted seats and temp that was previously used when parking, or AC in the summer.
Using a 2019 Mazda CX-5
Thanks!
Correct! You have to set your climate settings to what you want in anticipation for starting it up. So in winter time when I remote start my car, if I had forgotten to leave the heat on full blast prior to shutting it off then I would get in without it having gotten warm 🥶
Thanks! ordered, installed and hid box just like you! Can’t figure out the sequence though to get the shifter in drive? Pressing the breaks once doesn’t do it 🤷♂️
Put your foot on the brake and hold it down for a few seconds, then the car will take over and then you'll be able to get the shifter in drive, don't try to put it in drive too quick
Thanks!
👍
Hey where can I get a remote starter that works with a 2012 Mazda 3?
Great video, thank you! Ordered one from Amazon today. Quick question: How did you route the wiring into the fuse box area. Did you have to remove any additional trim? And did you zip tie the module to anything in there?
You are welcome! No, you really don't have to remove anything, there is enough space behind the plastic to just feed it through. Once it's in there, it's pretty secure actually, does not move and nowhere for it to go so I didn't bother with any zip ties.
@@radieyevanov So helpful, thanks!
@@danstackhouse7973 anytime 👍
If I have 2 factory remotes, will they both work, or does it not program the factory remote itself but just the locking sequence tell the device to start? That way either remote would work? Also, I read it will turn off after 10 minutes. I'm assuming the doors would be locked during that 10 minutes as well as remaining locked after the 10 minutes. Is there a way to program a cycle? 10 min on, 10 off, 10 on, etc? Otherwise, awesome video, very easy and clear to see what needs to be done!
Hi Andy, yes both remotes should work. Mine stays on for 15 minutes before auto shutting off. Not sure if there is a way to program it to stay on for longer, would have to message the company to try to find out.
Your video and instructions not only clear but easy to follow. I purchased a 2012 Mazda CX-9 with a factory remote, once I press to start the dash lights flash on/off and you can hear a clicking like the car is trying to do something but it doesn't start, not till I get into the vehicle and close the door THEN IT STARTS. I replaced the remote batteries, followed the remote start instruction that came with the vehicle, the dealership is no help & other shops wouldn't touch it cause it's factory. I'm thinking disconnect the NEG for 5 or so mins the try again, but I've called the local Mazda service & they said to bring it in and they'll look at it🤑💸🤑. Do you have any ideas? thanks..... MJ
Sorry Medic, I don't have any experience with the factory remote set up. In fact I got the start-x myself because it seemed to be the simplest one I could find
Is it normal for the car to act a little weird after installation? like i started my car and got into it 5 min later and when i opened the door my car turned off...
Will this work on a 2020 CX5? 🙏🏼 Great informative video btw
I think so. Though can always shoot startx an email to verify.
Hi! I have a 2016 Mazda6 sport, and wanted to see if you knew of a way to make all the windows go down before actually entering the car? I see some other models have that function
I do not know if a way sorry
@radi eye vanov I've only seen recommendations for the compustar system and not this one, but this video convinced me to get this. Thank you for the extra tips.
Do you know if there any way to have it auto turn on heated seats + steering wheel when remote starting?
It's a nice starter in that it's so easy to install and can do it yourself. It's not advanced like some other vehicles or abilities to control certain things like what you mention. So the way to do it with this kit is to make sure you leave the desired settings before you shut the vehicle off so that they turn on when you remote start it. ie in winter make sure to leave the heat on and heated seats on and in summer the ac on
@@radieyevanov thanks. As far as I'm aware Heated seats/wheel reset each time the car starts up but I'll look to see if there's a setting for that.
Also there shouldn't be any installation difference between this model and the unlock-lock-unlock model, right?
@@dinman correct! No difference at all. When I got mine only the 3x lock was available but I'm guessing they came out with the lock-unlock-lock because some people have the tendency to click lock multiple times sometimes to make sure the car is locked. Though this is only my guess. Either way: links to both versions are in the description.
thank you. I'm hoping the unlock version will be less annoying for my neighbors haha
@@dinman haha yeah good point actually, I didn't even think of that 👍
How can I get this in kenya . Africa
Thank you for an amazing video. I have onky one issue, when I start my Mazda with the remote start I'm not able to use my cruise control and auto brake hold, but when I do normal manual start it works perfectly. Do you know how I may solution this issue?
Oh I'm sorry, I don't know anything about that issue. Message startx support directly, maybe they may be able to help.
@@radieyevanov Thank you
Have you had any issues? I installed this on my 2014 Mazda 6. Followed your video essentially and it worked just fine the first two days. Since then, it turns on the car. But when I get in, I press and hold the break, then press the start button, but it shuts off the car. And it’s intermittent. Doesn’t do it always but has been doing it more frequently. Have also tried to hit unlock twice after it remote starts the car. Get in press the break and start button at the same time. I’ve tried unlock just once and different ways. It will still shut off the vehicle defeating the purpose of the remote start.
You are not supposed to hit the start button 🙃 just keep your foot on the break til the car takes over control and then drive away. Have to have the key fob inside with you obviously.
@@radieyevanovthat I did not try. Thanks again
great video, where can i get the one for mazda cx-3 2018
Amazon! Sadly the price went up. I think when I got mine it was 215 or so, now up to 290 😔
www.amazon.com/Start-X-Remote-Starter-Mazda-Miata/dp/B08XYF618C/ref=mp_s_a_1_3?crid=28KQR35QQ5UQZ&keywords=start+x+mazda&qid=1652542550&sprefix=start+x+mazda%2Caps%2C98&sr=8-3
hey, when you exit the remote start by pressing brake pedal for 3 seconds, did you notice the AC stops blowing for like 1 second or so and then comes back?
Yes, that's because the electric power is reset for a moment when the car takes over vs the remote. Normal
@@radieyevanov thank you for your quick response ! great video btw.
@@MarekMarciniak no problem! And thank you 🙂
What's the range like? I keep reading complaints online that it doesn't reach far
It uses the factory keyfob so it doesn't extend the range at all. Whatever your factory keyfob is that's it
Can I start the car the normal usual way after installing it? (Hold down the break and push start button)
Ofcourse 🙂
Do you have the link where you got this kit from. I looking to purchase one for my Mazda6

Great Video .. it’s working and I followed your instructions.. qq thou .. the remote key module in your video it does seems like it fit right into fuse box .. the one I got i couldn’t figure out a way
I believe I fed the wires in through the back and then the module through the front, connected them and tucked it all in
As of know I just placed right next to fuse box .. what happens if I take out connections and re connect it and tuck it under dash .. do I have to re sync the module ??
@@durgaprasad-mr4ld I would assume so.... Only one way to find out 🙃
Hahaha .. will let you know .. I bought it for $280 kind of expensive but here in Texas, my afternoons got little better during this heat
@@durgaprasad-mr4ld yeah they went up in price. I think they were 220-230 when I got mine. Still much better then something from the stealership though!
it is compatibe with Prestige CARLINK Remote Start (ASCL6) ??
Nope. Standalone product for use with factory keyfob
Hi I was wondering if you would know why my lift gate now won’t open at all?
I do not know why that may be! Does the key fob work for everything else? PS when you say won't open at all, do you mean even with the latch inside the car? Because if that's the case then it won't have anything to do with the key fob
I recently installed one on my 2016 Mazda6 Sport and it intermittently doesn’t let me use all the “infotainment” options that I did before.
Hmm...that's strange! What exactly doesn't it let you do?! Like your infotainment system isn't working properly or all your presents are gone after disconnecting the battery?!
I have the same car and I'm thinking about doing this, did it ever return to normal?
When vehicle is stated, can you shut the car off with 3 presses also? How?
Nope, can't do that. It will shut off after 15 minutes on its own
Do you need both key fobs to program it? (I only have one fob). And I am assuming it works on all 2014 Mazda 3 trims? I have a GT
Only need one! And yes all trims!
Awesome!! Thank you!! I'm too cheap to buy another fob lol

Won't work for 2012
How far do you have to be before you can start your car. Normal range?
Yes, the normal range of the keyfob
This screen that you have changed activates the touch function car in motion, excuse my ignorance, thank you
When the car is not in motion or going very slow the touchscreen remains active/functional. When the car is in motion it disables the touchscreen functionality.

Would this work on a Mazda CX-3 2019?
I believe so
Can you tell me where you can purchase this start-X
They use to sell directly through their webpage but aren't at the moment. They sell on Amazon but they went out of stock recently. Probably because of winter and them getting sold out. Hope they will get more soon.
was your car running during the programming?
No
Some poor sap is going to be overjoyed when he buys this kit and finds this video!
You cant even take a bad take.. that flub at the end was scripted 😉
Hahaha it most definitely was not scripted! 😅
I just purchased the start-x starter for my 2014 cx-5 and with your video I'm hoping it goes smoothly. I'm also looking at the Carlink ASCL6 module to allow for remote start via smartphone. Have you thought about installing it? I would be great to see you do a video on incorporating that module.
I actually purposely chose one that uses the car key fob instead of smartphone app. Personal preference but for me there's a lot of things in life where I don't want to rely on having my phone for. It certainly is cool technology though!
Where did you pick up the start-x from?! Seems it's been out of stock and nobody the comments section has been able to find one!
@@radieyevanov okay thanks for the quick response! I wanted to use the phone as a primary way to start it and have the fob as a secondary. The start confirmation with my phone is ideal for my workplace. I had it in my Amazon cart and been checking it periodically throughout the week. It went available a couple days ago for $299. I checked this morning and it was $219 so I quick purchased it.

Hi need help on my start x for my 2019 cx9
After i reconnect the negative terminal the led light on the module is solid red i push the start button twice it flashes green and after i waited for sometime it turns red😅 please help thankyou
I'd recommend following the reset procedure in the pamphlet or restart/redo all. If you still have issues. Reach out to startx directly (email in pamphlet or website). Their customer support is usually quick to respond.
Will this program work with a 2022 cx5?
Yes it will! 2 options available now. Can check both out with links in the product description.
Planning on installing this on my 2017 mazda6. Does the car shut off after you open your door?
No sir, has secure takeover. Once door is unlocked you have 45 seconds I think to hold down the brake pedal to take over. Must have your key fob inside the car.

do you have a link to the product
The link has changed a couple of times. Just go to Amazon and type mazda startx and you'll get the current available options 👍
I presume this is only for automatic transmission. You wouldn't want to remote start a car with MT that is parked in 1st gear :)
Hahaha absolutely right!
does it keep the car locked ?
Yes!
when you remote start the car, unlock the car, then open the door, does the engine shut off? it does that on the OEM remote start on the app, i hate it.
No it does not. It gives you plenty of time to take over control before any shut off

@@gsent56 welcome!
Is this for auto trans only?
Yes, auto only!
I plugged the three cables into the remote module and see the solid red LED light up . But when I push the car"s start button twice, the red blinks and I don't see green. Are we supposed to connect all the cables into the remote module? Am I missing something??
Hey Sambit. Yes, all three plug into the module. Try the reset procedure. Should see it in the pamphlet that came with it. There is a button on the module to hold and reset it and then you do the programming procedure all over.
Did the reset. Orange light came in briefly, followed by blue and solid red. But pressing start button twice only makes the red light blink. Waited for a long time, the electronics keep humming, but nothing happened. Have taken everything out so that I can use the car. 2019 cx5
@@sambition hmm interesting. I was gonna say to try disconnecting the battery and trying it again to see if that does the trick. Can always give it another full try from scratch since you have it out but if it continues not to work I'd contact their customer support to see what they say. Did you buy it from Amazon?!
@@radieyevanov yes, from Amazon. Have contacted customer support. May be the unit is faulty.
@@sambition I hope it's as simple as that and they send you over a new one 🤞
Aw my Mazda is 2012 CX5, there wrote 2013+ so I guess i cant get it..
Could I start the car from a block away?
Probably not. It's the same as what ever the factory keyfob range is. You are using the same keyfob obviously so it doesn't change anything in terms of the range. If you can lock and unlock your car from a block away at the moment with the keyfob then it should work.
Is there one for 2006 sienna ?
Yes they do but the 2006 kit is not a plug-and-play kit. It requires wire splicing and the install is much more complicated. The plug-and-play kits are typically not available for older vehicles.
Where from can I perches such a remot for my 2015 cx9 mazda
This particular starter is a plug and play and only for 2016 and up cx9. You would have to purchase a different one for a 2015 that would require to be wired in as opposed to plug and play.
Is there a trick to getting the two white connectors unhooked. I can’t get them off. Thanks
Hmm...no trick. Should be like any other auto electrical plug. There should be a spot to push down while pulling them apart to separate. I'm sorry, I don't remember if there was anything different about them as I did this install a while ago.
I don’t see anything to push down but I will look tomorrow
