Locksmith Tool | Master Pin Follower

The Pro-Lok Master Pin Follower, part number LT370, is the coolest follower for any locksmith. Aluminum makes up the Pro-Lok Master Pin Follower. Each end has been cut off, which is perfect because it will suit the back part of the tailpiece that protrudes in mortise cylinders. On the other side, you'll find an excellent wider cut-out on the opposite end. Now, the middle section is what distinguishes it as a master pin follower, and the whole function of a master pin follower is based on the groove that's been cut out, which is ideal for simply spinning around to remove all of the master pins. Instead of inserting your usual follower, take it out and double-check that no master pin is trapped in either of the chambers within the bolt.

REKEYING AND TAKING OUT MASTER PINS USING A REGULAR FOLLOWER

To rekey a lock with a normal follower, you must first carry the follower through and then go to the lock to rekey it. Then you must look for all the master pins. To do so, turn the lock around, align it with your follower, and enter with a pair of tweezers, checking each chamber. If a master pin is present, remove it in the same manner.

How to remove master pins on a lock

There might be top pins that won't come out by doing it. These are not low enough to where they're going to fall out themselves, but it's cut down far enough so where all the master pins are going to. They're just going to be sitting there, and if you rock it, just a little bit, it will knock them loose, and they're going to come right out.
