Re-keying your locks, The how-to thread Options

[markb]

I was re-keying a lock for someone today, and thought it might be a good time to take some pictures & explain how you can do this yourself. It’s not rocket science, if I can do it, anyone can do it. Please correct me if I’m wrong, or use the wrong terminology.

I’ll start with a door handle, because that seems to be what needs to be re-keyed the most.


Your standard 914 door handle.

Now you can get to the housing. This housing has the wires hard-wired onto it, so make sure they’re straight, and use a pair of pliers to gently pull the housing forward. The key needs to be turned to release the steering wheel lock. You don’t need to remove the whole housing to pull the switch (Yes, I know, the key on this one is broken off).

Once the housing is pulled forward, you can access the hole that you use to release the tumbler.

This tumbler is much smaller than later years.


Here is a rear view of 3 tumblers. Left to right:
An unbroken tumbler, next is a broken one. This has happened to me a couple of times when pulling the tumbler apart. It develops a crack at one of the holes when you pry the back off. Notice the holes are different sizes so it only fits on one way. The last is a JB Weld fix done by a PO. I’ve used the same method myself, and it seems to work OK.

Once you’ve pried the back off, you see the 3 pieces.


Re-key the tumbler. Assembly is just the reverse of disassembly.
When you reassemble the tumbler, tap the pins that hold the back on with a punch or chisel to spread the pins slightly. If the pins don’t spread enough to hold the back on well, you may need to JB Weld it as shown above.
Not as tricky as the later (75-76) are going to be.
