Little off topic though but I went to the local antique chevrolet junkyard for a new ignition switch for my 63, got one but the guy didnt have a key so I drilled it out once I got the lock tumbler out I saw it had the same key code engraved in it as my orignal key. I could have used the key on my car to get that lock tumbler out. What are the odds of something like that happening.
Im sure its more common with model T`s as I think they had something like 4 or 5 different keys for all their cars.

Same guy also took the door and ignition locks from an 86 F350 crew cab, 91 "Super Chicken" (T-bird super coupe) and 95 F150, and had a locksmith set them up to use the same key. He got tired of always grabbing the wrong set of keys when trying to go somewhere.....
Naturally, he lost the key, and was kinda stuck. By stuck, I mean the only vehicle he could drive, was a Cobra replica, except it was blocked in by a couple of the others that he lost the key for....... And, that was one key he didn't have in the box.......

Well if it's any comparison, when one of the door locks broke on my '80, I pulled one from an '85, which used the oval key. That key also worked for the glove box lock that I pulled from the center console of an '89 Bronco, and the glove box lock on my '92 that I never had a key for.

Correct, except the ignition lock also failed so it uses a different key now too. The original ignition key still unlocks one door. Same situation with my '92, I had to replace the ignition lock in it too. One of these days, since the '92 is being converted to appear as an '80/'81, I'll probably use '80 style locks in both of them and either have them both keyed the same, or have one side of the key cut for one truck and the other side for the other truck.

I would swear that I posted on here last night, but I sure don't see it. My guess is that the gremlins taking the servers down ate it.
Anyway, I got two responses from dealers who have the 80 ignition and door lock sets. One wants $52 for a set and the other wants $65. I was inclined to go with the $52 one until I remembered two things: First, I've been promised a locking hood release with the ignition, glovebox, and door tumblers. Second, I'll have a security system tied into the power door locks so will rarely use the door key. Given those two things I think I'll wait and see how it comes together.
But, thanks for the help clarifying the situation. I think we can now safely say that in 80 Ford used a different door lock than was used in 81-86, and that door lock used the same key offset as the ignition key. And, some of those sets are still available.

I do consider myself an expert on this subject, but only for the post-89 or so vintage. Did you read my story about replacing my ignition? It is for a later date, but it looks like it's a similar setup. Using one key for Ignition and Doorlocks after replacing the Ignition Cylinder - Ford Truck Enthusiasts Forums

And, reading the post you linked to....... to which you linked, I can believe it. Wow! What a lot of detail. But, just 'cause you are laid up doesn't mean I'm going to relinquish my crown - Master of Trivia. But, I'll gladly share it with you.
So, is there any chance that the ignition tumbler from, say, a '96 Bronco will fit an '81 F150? I'd bet the door locks will, but kinda doubt the ignition tumbler will. (But I'd bet the tires and wheels will!

'80-'91 ignition locks will work '92-'96. Not an exact fit, wiggles a bit, but the grooves are cut similar. I never tried using the newer one in an older truck but it looks a bit bigger. Door locks interchange between all. '80 and '92-'96 had the offset like the ignition key, '81-'91 had the regular oval door key offset. The only difference between the '80 and the '92-'96 is that the latter used slightly longer, 10-cut keys. Physically though, they're all the same.

Just for giggles, I looked up door locks at autozone and oreilly. Both showed the same part number, and the same pic. In the pic, it clearly shows a square head key, which would be correct for an 80. But they both list them as fitting 80-86, which is not quite right.......
Ignition locks claim to fit 80-91, which fits with the info posted previously.
