Im trying to get some info how the door handles and locks work. I have a key cylinder on the passenger side door (seized up). Im trying to find a replacement lock cylinder with a key so i can lock the doors. Was this a factory option and was the drivers side supposed to have a key cylinder also? I have found replacement for the F100 but not the f1. If you lift the door handles the doors do lock. Thanks for the help!

 

First of all, there was no driver's door lock until (I think) 51 in the 5 Star Extra cab.

The door locks are available from multiple vendors.

And until you fully understand how that lock works, keep the windows rolled down. You can be locked out.

 

Listen to Ray. The inside latch lock is a separate function from the outside key lock. The key cannot unlock the latch if it's locked from the inside. Beware.

 

LOL good to know.. thanks guys

 

Hey Sped,
The door locks are pretty interesting on these old trucks. They were designed so you'd lock the driver's side door from the inside then slide out the passenger side - avoiding getting run over by passing traffic.

The door latch is a little different as well - there are (2) latch points in there.
If your door doesn't fit tight - you may only catch one of the latches - then go over a bump & the door swings open. A lot of us have upgraded to the bear claw style latch by Altman & others.

Good luck over there.
