How To Replace Door Locks And Cylinders

We're fitting this Mustangs Unlimited door lock with an aftermarket rod retainer made of nylon plastic. It's quieter, for one thing. For another, it will remain secure for years to come.

The lock is inserted like this; the spring steel clip is reinstalled inside. We suggest the use of Ford's original retainer for best results.

Reconnect the rod and perform an operational check. Make sure it works before buttoning up the door. Reinstall the door panel, handles, and armrest.

Glove CompartmentFord offered an optional glove compartment lock, which came with the Convenience Group. This is a nice feature for those who want some measure of security for odds and ends. Two self-tapping screws retain the lock. You can change this lock in a matter of minutes.

This is a '65-'66 Mustang ignition switch. Installation is an easy press, twist, and turn step. The spring is what secures the switch. For '67-'69, a fine-thread escutcheon retains ignition switches.

To remove the ignition switch lock cylinder, insert the key and turn it to the "ACC" (accessory) position. Insert a paper clip into the small hole below the key and push in. When you turn the key back to "OFF," the cylinder should pop right out. If you don't have a key, the ignition lock cylinder will have to be drilled out or the entire ignition switch replaced.

To install the new lock cylinder, insert the key and push the assembly into the switch with firm pressure. Turn to "ACC," then back to "OFF," which should secure the lock cylinder.

This is a '67-'68 ignition switch with a fine-thread escutcheon. The lock cylinders were taken out just as they were in the '65-'66. For '69, expect to see something similar.

For '70, Ford switched to a locking steering column, which has the ignition lock cylinder at the top of the column and a linear switch located near the bottom. Lock cylinder removal involves removing the steering wheel and releasing the lock.
