Kits are available for most lock brands and come equipped to do multiple locks, but frequently work for only locks of the same brand. [1] X Research source Some kits include only lock pins, while others include special tools (cylinder follower, ring remover, plug follower) to remove the lock cylinder so you can replace the lock pins. You can order extra pins if you have more locks to re-key than the kit has pins for. If you have any old locks that are too corroded to keep, take the pins out and keep them before you throw the lock away.
Keeping constant pressure will keep the upper lock pins and their retaining springs in place when you remove the cylinder plug. If you should let the springs fall out, you can still pick them up and reinsert them but you will need tweezers to put the springs and pins back in.
If the pins are not coded, you’ll have to use trial and error, inserting and withdrawing the key to make sure it fits the lock with the new pins installed.
The key does not have to be the one that is normally used with the lock.
If you’re rekeying more than one car lock, be sure to arrange the new pins in the same order in each lock so you can use the same key with all of them.
