How To Rekey a Residential Lock (Tips and Tricks)

In this video you will learn how to rekey a residential lock even if you do not have the original key.
Here are the rekeying methods that I cover in the video:
First, you'll learn how to remove the lock cylinder with or without a working key as well as learn how to decode a lock. This is a helpful trick when your lock doesn't have a key.
Next, I'll show you how to shim a lock when you do not have a key and add pins to a lock so you can create a new working key. Awesome information if you just bought a new home and want to feel more secure knowing that who ever has a copy of your key, will not have access to the locks anymore as well as save money from hiring a Locksmith and not having to purchase new locks.
With this new learned skill you will be able to rekey the locks in your home so you will only need a single key to open all of your doors!

Where did you buy your caliper

[@thewhittierlocksmith121]

i bought that one on amazon. I usually hate that caliper, but its perfect for measuring pins- due to the flat platforms

In the 80's my friend worked with a car repossesser. After towing a car from a rough neighborhood, he would sometimes stop in the gas station as a safe zone and make trunk keys. He would take a blank (I think) and wiggle it back and forth in the lock with a vise grip, look at it, then file the blank one spot at a time, I never really paid much attention, he might have been using other tools/pattern masters (not sure), but within about 5 minutes (going over and over again) he had a key to open the trunk. How is this done?

That is called impressioning.

@@thewhittierlocksmith121 Thanks, do you have a video on that?

@@paulromsky9527 not impressioning, but I have a video where I cut a key by looking at the wafers. Impressing is just turning the key in lock to get marks, then you file those marks and repeat till the lock opens, that creates a key

@@thewhittierlocksmith121 Ok, watching your other videos, so I guess the tumblers make marks in the blank, I guess when a mark stops walking down (the gap at the shear has been reached) you stop filing down for that tumber. I think I am going to try it on an old lock for which I lost the key.

Love the idea, but this is not possible with European. The keys don't have numbers, and I don't think you can get the barrel out of the lock

Just a tip, edit the Videos. Like saying mm when it is Inches or talking about manufacturing process you know nothing about. When you measure, the instrument you use is not real suitable as it is in the kind of sideways when you take the measurement. the reason you see a variation in size is called a tolerance. Materials also grow and shrink as temperature changes. So the measurement would be different in 30F weather vs 90F.
Over all it is informative.
