Design Changes to the Kwikset SmartKey

- This is not a picking video. Kwikset has dramatically changed the design of their SmartKey system, making it much more difficult to pick. I evaluate those changes and strategize on an approach to picking it.
Very Interesting & Cool To See The Two Designs. Keep up the great work. Nick.
Thanks for the callout, I'm glad you're having the same fun with this that I have been. You're going at it slightly differently than what I've been trying with shims... I was trying to shim between the housing and the cylinder with a flat shim folded or curled on the end to try to put tension on the bar in that open slot about midway down the length. The problem I had with that is I could get a small amount of pressure on the sidebar - enough to feel the gates click into place, even - but not enough to overcome the pin spring pressure, so they'd immediately drop after I set them. I hadn't tried going thru the ball bearing hole there, but seems like that could work. The only way I've managed to pick it so far is with the cylinder out of the housing, and rubber-banding a small metal rod against that exposed part of the sidebar... cheating, obviously, but it proved that adding pressure there would work. I've killed a lot of shims trying to find a way to fold or curl it in such a way that it would snap in there and deform when pushed or pulled... I'm convinced if you could get one to roll up on the end as it's pushed into that opening, effectively creating a little barrel spring, it would work, but I couldn't quite get a shim to roll that small once it had been straightened again to get it into the slit from the front - there's only about .065" of space to work in there.
Nice video. A couple thoughts: 1- Your idea is very similar to datagram's attack on the old style MT5+ sidebar (with which I had some very limited success). Though he did it so you could progressively tension the sidebar (i.e., bind one slider at a time). 2- Do the sidebar springs have enough tension to create audible feedback when lifting the pin/slider assembly? If so, that might be a good way to decode the lock... That particularly true since the true gate is HUGE, so close should work. 3- How new is that lock? I got a SK at Home Depot a couple months ago, and it had the old style sidebar.
Thanks for the great explanation. Looks like Kwikset has done a pretty good job here. I wonder if they did these changes to make the lock more secure against picking (what is probably a rare attack in real life) or for other reasons. Looking forward to see it getting picked someday. Cheers :-)
Just a thought could you take the reset tool and apply pressure once you have it picked to release your tension wrench so the side bar will drop and thus allowing the cylinder to rotate???
i was going to buy a new schlage or kwikset deadbolt at menards. any recomendations on model? its for residential.
Hi. Very nice video. I recently had a smart key lock installed on a new door at home. I have been interested in locks for decades. So I did some research to see how the smart key system worked. I just viewed your video. It looks like the revised kwikset smart key system is a "dead ringer" for the general motors steering column ignition locks used on their cars from 1969 until probably the 1990's. These were the column locks that had the "ears" that were used for the rotational force. The keys back then were thin and weak against rotational force. The side bar was squared off to prevent it from being picked down by rotational tension. The quick picking method was using profile keys. Locksmiths would have a set of about 10 and the process was trial error. The other method was more destructive. It involved drilling a hole in the end of the lock face to access the end of the side bar. Then use a pin (such as you are trying) to provide force on the side bar to pick it down. The GM locks were not rekeyable so the wafers were a simple one piece design. Of course all of these anti pick devices took a back seat to the VATS lock systems that came along in the 90's.
Will this new core design fit the old SmartKey locks and will Kwickset provide them as a warranty replacement?
Here's an idea! Try bend shaping the pin with the corresponding depth entries, using a needlenose plyer and shaping it into the shape of the sidebar entryway, so that the tip of the pin will fall into place when it reaches the sidebar. Then when the pin is turned it'll put the sidebar in place.
Anyone know if this design change with the squared side bar, will strengthen the core against force tool attacks ??
Wondering why a squared off side bar was not done in the first place. Also, is there a lesson here of something added to the manufacture of a plain pin tumbler lock to similarly deny tensioning.
My first thought is: is that bar made out of a ferric metal?
How can I tell if a Weiser SmartKey lock is the second generation? Without disassembling the core. I bought it in 2013.
Totally agree the AssaTwin is the machinist treasure to have beaten. I was never a fan of Kwikset because it’s lack of tolerances and builder grade evolution. The early versions of the Kwikset smart key were easily defeated. Now, The Square side bar under spring tension is what GM has done from the 1960’s. As a locksmith we would use Wiggle jiggle keys or more modern techniques were to use set of rockers blades. With GM you would use car opening tools and to make the ignition key, pull the wheel and lock and just replace it. As for the Kwikset, this newest design, it lends real locksmiths called in for a lockout two choices, rake and rock for 3 or so minutes, then drill. I don’t see how a bump key would ever work - so for that, I applaud Kwikset. I would be very interested in tumbler 3 non destructive pick or manipulation of this lock. I say, exploit the tolerances and gaps.
please could you tell me the name of this law it did not mention it other than that it was a Kwikset Lock..
I lost one of the little round springs that gets trapped between the c-clips what can I do
It seems however that if u used a kwikset rekey tool to put tension on the wafers and then proceed to pick, u could then get an open on the lock.
I wonder how much it would add to the cost and help to plate the surface with titanium so that drilling isn't possible without an expensive drill, bit and a lot of strength and time. That should even save the lock from that attack almost every time.
what if you ground down a kw1 key to the bottom and left some of the bow. on the key and used it as your tension to control the sidebar
Hey, i think i may have a solution to your tensioning problem, i been trying to pick this thing for a while and i "accidentally" rekeyed mine to something other than the key i had for it, as i was pulling it out, the sliders got stuck on the outercore and as i pulled on it, they would bind and i would pick them one by one until i got the core out and rekeyed it again manualy. However it gave me the idea to use the rekey mechanism as a tension device, it seems to work, you push on it with force and it bind the pins but not the sidebar, give it a try, i have not been able to pick it, but the pins do bind
