(97) How to repin locks 

Thank you. Every so often I remember things that mystified me when I started out and I try to come up with tutorials. If there are any topics you can think of, let me know and I will see what I can do.

Thanks. Glad it turned out well.

Thanks. I figure it would make a good example.

Hope it was helpful.

Thanks.

2 years later and I am in this exact situation

Glad you liked it.

That is LAB's Mini DUR-X kit for Sargent (LMDSGT). You can find it from many locksmith suppliers and online retailers.

google it

Sargent uses a 'graduated driver' scheme, as the key pin gets longer the driver pin gets shorter. There are two reasons for this: 1- With very short key pins when no key is inserted a driver pin may not be long enough to block the shear line, this leaves the spring as the only thing which blocks the shear line which will damage the spring and lock. 2- With very long key pins a driver pin that is too long may crush the spring or even prevent the key pin from being able to clear the keyway when inserting a key, this damages the springs and can prevent the lock from working. If you can, take a look at the Color Passport charts from one of LAB's universal pin kits, it shows what length driver pins are required for different key pins.
