One Key System?

It has been mentioned before that the 80 trucks came with one key for both the ignition and the door locks. I'm quasi-interested in converting to that so RW and I poked around in the parts manual today and came to the realization that the same steering columns were used in the trucks from 1980 on. So, it would seem the ignition lock from an 80 will fit in a later column like mine. Given that, I have sent some requests for pricing to a few places that have the set of ignition and door locks.

However, I thought I'd ask to see if any of you know what the differences are? And, if there would be any problem using the 80 ignition lock in a later column? (My guess is that the ignition lock is the same, but the door locks are different.)

As said, I'm quasi-interested. I can see but one advantage to having two keys, and that is because Fords of this era had two keys. But, not all of them did.

I would say change the door locks out as the door key has a reverse angle than the ignition key does. Then have the door locks rekeyed to match the ignition lock.

I think what you are saying is to find an 80 in the salvage, or find NOS door locks for an 80, and then have them re-keyed to match the current ignition lock. But that assumes that the door locks are the only difference. Do you know if that's the case? And, that they can be re-keyed?

Well my Mercury uses the same square key for the ignition switch for the door locks as well. The oval headed key is used for the trunk. On my 82 F150, the square head key is ignition while the oval head key is door.

I have to get the part numbers but I can look at my parts and illustration guide and see what part numbers are listed for a 1980 truck door lock and ignition lock.

I would assume they would interchange but you want something more specific than assumption.



Also LMC sells the door lock set with keys, for 1980 thru September 1980, and another set for October 1980 thru 1991.

I'm kinda curious about this too, since I don't know exactly what year truck that column I bought came from. It doesn't have the key switch, so I'm hoping I can just swap my 80 switch over to it. Wouldn't matter much, if not for the fact that the same key also fits the doors......

Everything I can find, seems to indicate the key switch is the same from 80-91, so it would seem that my switch should swap right over.

Well for F100/350, U150 for the ignition lock cylinder & key is for 1980 and up. Cant say for anything after 1989 as thats as new as my catalog goes.

For the other lock though this is what I could find is that theres quite a few combinations. But the only ones I could find with a single key system though is below.

80/81 F100/350 -- w/security lock group & underhood tool storage "Before 10/80" ; F/D, G/C, I, & H - Includes spare wheel lock : E1TZ 1022050-C

81 F100/350 -- "Before 10/80" ; F/D, I, H - Less spare wheel lock : E1TZ 1022050-B

81 F100/350 -- "Before 10/80" ; F/D, G/C, I, H - Less spare wheel lock : E1TZ 1022050-D

Now these dont say if they are single key system or not but I dont think they are.

80/81 F100/350 -- "Before 10/80" ; F/D : D8BZ 5421984-A

81/85 F100/350 -- "From 10/80" ; F/D : E1DZ 5421984-C

This one below is listed as a dual key system though.

82/83 F100/350 -- F/D - Black Chrome less spare wheel lock : E2TZ 1021984-A

Based off this I would think the door lock cylinders were the same for the one key and the two key systems on how they attached to the truck.

The columns were slightly different in 1980, but the lock cylinders can be used in columns from 1980-91, they are the same. These ignition locks can also be used in trucks up to '96. Not perfect, but they function just fine, just thought I'd throw that interesting fact out there. The square-head ignition/door combo key was re-introduced for the 1992 model year as well, the oval-head key was only used for the glove box. That may be an option, but I don't know if the reverse of what I said above is true, I'm not sure if a later ignition lock will fit an older column.

Correct, door locks fit and function the same up to '96/7, up to 2000 on MD trucks.

So he should be able to pick up some door locks for a 1980 F-series truck that has the same grooved style key as the square ignition key on later trucks and then have the door locks rekeyed to match his ignition key.

I know it can be done cause we have lock cyliners rekeyed all the time at work.

Looking at the keys to my truck though, the oval key has a reversed cut than the square ignition key. So I would think the door locks themselves for a 1980 one key system would have the cut the same as the later square head keys.

Rusty - Thanks. I'm seeing the same thing in the catalog.

Ranger - The catalog shows the same exact part number for the steering columns on 80's as 81-86. So, what's different?

Paul/RW - We missed a bet today on comparing keys. Here's a shot of my two ignition keys for my 81's, and the door keys are backwards of these such that they won't of in. If your ignition key is like mine then your door locks must be backward from the later door locks or the key wouldn't go in. So, all I would need are the 80 door locks - assuming they can be reset to take a different key. Or, a full ignition and door lock set.

Yes, the 80 and older door locks were set up for the same offset as the later square headed ignition key.
My 80, and dad's 74, both use the same key for doors and ignition. Ironically, my brother once owned an 86 Ranger, and the key for my 80 would start it but not unlock the doors (needed round key). His ignition key would fit the doors and ignition of my truck.....

Did not need to compare keys. I already know the same blank fits the ignition from back in the 60's, to around 91.
Yes, the door locks are reversed so the square head key can go in.
Not sure, but I'd bet door locks from 70's trucks would also physically fit and work fine.

As do the '92 and later trucks, but they use a 10-cut? key, so I don't know if they could be re-keyed to use an older key. As for the difference in the columns, it was the neutral safety. 1980 trucks had a physical lock to prevent turning the key to "start" if the truck was not in park or neutral, 1981 and later had a NSS on the transmission and no such lock in the column.

I'm thinking you may be right. The 80 was a carryover and wound up with 70's stuff.

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.
