The original ignition cylinder in my 78 is getting sticky. I got a new key cut but that didn't solve the issue.

I replaced it with a NOS cylinder but was wondering if there is a way to rekey the new cylinder so I can use the original key ?

I have seen the thread where it can be done on new models but wondering if it is possible on 78/79?

On most vehicles a locksmith can do that. And it's a lot cheaper if you bring the cylinder into his shop instead of having him drive to your house & take your truck apart.

Another option is to cut the door key pattern onto one side of a key & the ignition on the other. Each cylinder only uses one side of the key at a time.
Normally the extra teeth on the back are so you can enter the key either way. If you cut 2 patterns the key can only be used with the correct teeth oriented one way in the lock.

I've done this in the past & cut a notch into the key head to keep track of which side of the key to use where. On a 70 Merc it worked out so that the notch went up in both locks. That was handy.

On my 78 my key was being really stubborn. Basically, the key was really worn down, so if you made copies you'd end up with a copy of a really worn out key.

I left my Bronco with a local locksmith since it was just down the street, you could just pop out the cylinder, and he made a new key from a blank by using the pins in the lock itself and it's like having a brand new key. The key works perfectly and doesn't bind up in the locks. If I make a copy from it, I'll get perfect copies again as well. I'd try that out.

Forgot to answer your question, yes, a locksmith can rekey the new cylinder to match the old key. They can do the same for any of the other keys as well. I don't know about anyone else, but my single key unlocks all the external locks on my Bronco and also does the ignition.

What people have said here. I got new lock cylinders for my Bronco, but the tailgate was the other keyway oval headed key, I went and got a lock cylinder for my tailgate from the local junkyard and took it to my locksmith with the key that fits my doors and ignition and he re-pinned it to work with that key. Now all my locks are the same key.

I know it is an old post, but it popped up because of another thread. Simple answer is "yes". And since the late 70's Broncos used 1 key, in a heartbeat I would pull the old lock and have him re-pin it and code cut new keys.
