Locksmiths always say that they can a re-key lock, but who knows what that actually means? It’s easy enough to assume. They do something to the lock so that the old key no longer works. There are a number of reasons one might want a lock re-keyed. Maybe there was a break in. Or maybe you just lost your key and don’t want to risk someone trying to enter your home uninvited. Either way, the idea is simple enough. However, how exactly do locksmiths re-key locks?
Well, if you are adventurous or think of yourself as a regular handyman, then you should know that they sell DIY re-keying kits at hardware stores. Each brand has their own kit so before you head out to the store, make sure to check out the locks you want to re-key.
Now each kit is able to rekey six locks. It comes with pins, tools, and two keys. If extra pins are needed, those can be bought separate. The overall idea to re-keying each lock is the same. However, it is always best to read over the instructions anyway.
Step 1
Insert the key and make sure the lock is unlocked. Then, use the wire tool in the kit and use it to remove the doorknob by inserting it into the knob hole.
Step 2
Push the cylinder and pop it out of the knob sleeve.
Step 3
Using the retainer ring tool, push it against the retainer ring to remove it from the cylinder. Keep the ring because it will be needed later.
Step 4
You need to remove the cylinder plug. To do this, insert the key back into the cylinder and turn either right or left depending on the lock. Then, use the plug follower supplied in the kit and remove the plug. Make sure to keep a constant pressure. The plug contains the springs and pins in the lock. Though nothing will happen if these things fall out, it will be tedious to collect them all later.
Step 5
Dump out all the old pins and insert the new key into the cylinder plug. Following the instruction sheet, insert the new pins. They are color coded so it shouldn’t be too hard.
Step 6
Just as you took the lock apart, put it back together again. Stick the knob back into the door and voila! You have just re-keyed you lock!!
