I always check for master pins even in residential. Some builders use contractor keyed locks that contain master pins. On older homes it may have been a rental at some time that was masterkeyed. Never hurts to check every lock, every time. I find it doesn't take much time and I find master pins in locks where you would never expect them. #lockboss

I have never in life rekeyed anything, I watched this one time and understood the entire process. There is a guy here that is charging people to do this as if anyone has time to mail their locks to this guy and wait for it to come back. He also makes it seem like you must replace the wagers which you don’t. Thank you my man you are awesome

You missed checking the bottom pin to top pin sizing for each pin cell or chamber. When rekeying cylinders like Sargent and Schlage you must consider Pin Stack Height to prevent spring compression. If you replace a low bitting or smaller pin with a longer or deeper one without replacing the top pin the spring may crush when you insert your change key and may even trap the key. The performance of the cylinder may suffer due to "Key Insertion Pressure". If you apply the same considerations when replacing larger bottom pins with smaller you would have less spring pressure, etc. The CLK pin kit chart shown in the video shows the correct size top pins for each bottom pin. Be sure to check it out and use it when needed. Make another video explaining this and keep up these amazing and well constructed Five Star educational videos! You're a winner PJ!

As a new lock smither, that tool is nice

[Pyrolock]

I use the HPC TPIN-2 Top Pin Loader after letting all the drivers and springs fly out by just pulling out the plug without a follower (check to make sure all springs are out)-- Load up the HPC Top Pin Loader with new springs & proper size drivers. Then I know I've loaded new springs with the proper length drivers. A fast way to load springs & drivers (as long as you are aware to use the correct drivers in relation to the key pins / key bitting). A bit of a pain, but works for me
ALSO the Keedex "EZ LOAD" is a great tool for doing chambers one at a time -- simple & fast.

Man I've got to get one of those! That would have saved sooo much time.

I just bought the master key followed. The follower should have been made with a ramp on the top front so it can be removed out the back of the lock cylinder without trapping the longer top pins after the master pins are removed. Sometimes it can’t be rotated to remove the follower from the lock cylinder. Try it. Jim

cj, great video! i actually use same version of prolok follower.
it makes it so much easier. like how you showed everybody the correct way of using!

[aperson]

With that Pro-Lok follower, be careful of the engraving on the low area. I ran into the top pins binding in the engraving and had a heck of a time getting it to release them.

[daviddaly]

I use the master pin follower for every lock I re-key....without fail for the reasons you stated in the video.

[DarkEmpathy]

Not only for the cross keying scenario, but sometimes the key itself won't release. Which is a tell tale sign that a larger master pin is in the cylinder that the follow through tube didn't get.

[stuartfuller]

Keedex master pin follower is my favorite.

[rmsg]

Yeah try that with an F series, the top pins come out too regardless of the special follower. ON the plus side, I like the technique with the tweezers. Surprisingly I never thought of that although I might try it with a screwdriver instead.

[matsteele]

I tend to drop all top pins out for any commercial building rekey. I can check for master pins, check correct length top pins and that the springs are still good. Also provides a chance for me to upsell the client to spool or security pins for future pick resistance

[wallywrench]

Shove the tweezers in three deep drop the masters and repeat on the rear of cylinder. Favorite plug follower is what learned on HPC hollow brass follower. Still using the same plug follower from 1998 and on my 4 shim.

Brilliant bro! I won’t do this, but handy to ask my locksmith if he’s checking for those on my house. Idk if it’s standard practice to use master pins on a house, but nice to know!
