Cannot Get Either Door to Lock
On my 67 F100, I cannot get either door to lock. Pulling the handle seems to activate something mechanical but it will not lock. Even using the key does not matter. On the driver side the key will not budge the lock cylinder at all, and on the passenger side it does move the cylinder about 45 degrees, but it still will not lock. Also my ignition cylinder has to be jiggled for a bit for it to unlock. Should I simply replace all of the lock cylinders?

1967 doors are 1967 ONLY. Not the same as 1968/72.
1967: You push the inside handle forward to lock the doors from the inside. The doors can only be locked/unlocked from the outside with a key.
1968 and later trucks have door lock *****. With these, to lock the doors, push the **** down, close the door with the door handles push button...held in.
1967 vs 1968/72 F100/750 doors: The weatherstrips, division bars, glass, upper/lower hinges and door lock cylinders (but not the rods) are the same. EVERYTHING else is different including the bare door shells.
The Fed's (NHTSA) mandated that all 1968 and later vehicles have door lock *****. Prior to 1968, Ford trucks had none.
1967: You push the inside handle forward to lock the doors from the inside. The doors can only be locked/unlocked from the outside with a key.

Never done a 67 door panels, so can't help you there. On later trucks, you remove the up/down **** on top of the door, remove arm rests, remove inside door handle and then remove the perimeter screws on the panel...and off it comes.
NumberDummy...I've had two 69's, one a F100...taught me to drive back in the dinosaur days, and now a 69 F250 Ranger. Neither one would/will lock the way you describe...they only locked from inside with the ***** and from outside with the key...doors simply don't catch if you hold the push button on the outside handle in while closing the door. I always thought they were made that way...but I've been wrong a thousand times before...are you sure about the lock from the outside method in 68 and later trucks?

Ok, but I have tried that as well. It does not work either. The doors will not lock either way I try it. Handle or by key.on the passenger side, the lock seems to activate. I can tell because you cannot push in the exterior burton to open the door. But as soon as I close it it is unlocked again. Faulty latches? How do I even get the door panel off?
The rod is retained to the latch with a clip, which is very prone to breaking. If so, take the old clip to a parts store and match it up.
If you have a Standard Cab, you do not have a door trim panel. If a Custom Cab, be very careful removing the door trim panel as the clips that retain it are also prone to breaking.
And, if you have a trim panel, the armest has to come off first as it's retained to the metal access panel behind the trim panel.
The inside door handle connects to the door lock remote control which has a coil spring. The remote control has a long arm that connects to the latch.
When the spring loses tensile strength, the door cannot be locked from the inside and usually the handle just flops around. When you pull the handle back, then let it go...it will move back into postion by itself if the spring is OK.
tmcalavy: It's been a while since I've I owned a bumpside (1979), so I may be wrong on how the 1968/72 doors can be locked from the outside. I do know the cars with lock ***** operated this way as did later trucks.

tmcalavy,
I'm with you on this one. I have had my '72 for several years now, and there is no way to lock/unlock the door from the out side without a key. I actually tried pressing the *** and holding the thumb button in, while shutting the door. Didn't work. I had cars back in the day that would lock like that (my '67 mustang, IIRC was like that).
I actually like having to use the key to lock the door, because I no longer am able to lock the keys IN the ignition (sometimes with the engine running!). I did that several times in my '77 - I learned to carry a spare key in my wallet so I wouldn't have to call the auto service to let me in...
Live & learn,
John
