Ford F-700 Door Lock Kit Guide for 1981-1987 Models
Having trouble with your F-700's door locks? This guide covers the parts and knowledge you need for a successful replacement.
- Aftermarket kits from brands like Standard Ignition are the only reliable option for these trucks, as OEM parts are unavailable.
- Failure is purely mechanical; symptoms include a sticky or non-working key.
- Replacement is a simple, DIY-friendly job requiring only basic hand tools.
- A faulty door lock poses a security risk but will not prevent the truck from being driven.
Is Your Door Lock Failing? Common Symptoms
On a classic work truck like the 1981-1987 F-700, door lock problems are almost always due to simple mechanical wear. Unlike modern trucks, these models have manual locks without complex electronics. Watch for these signs:
- Key is Hard to Insert or Turn: If you have to jiggle the key to get it in or turn it, the internal tumblers are likely worn or misaligned.
- Lock Feels Loose or Sloppy: The connection between the lock cylinder and the internal door latch mechanism may be worn, or the retaining clip could be loose.
- Key Won't Work at All: The lock cylinder has failed internally, or the rod connecting it to the latch has become disconnected.
- Key Gets Stuck: A bent connecting rod or worn cylinder can prevent the key from returning to the correct position for removal.
Choosing the Right Aftermarket Door Lock Kit
For a vehicle of this age, new original equipment manufacturer (OEM) parts from Ford are no longer available. The only practical option is a new aftermarket kit. Fortunately, replacement is straightforward.
- OEM Parts: Discontinued. Finding a New Old Stock (NOS) part is extremely rare and would be very expensive. Used OEM parts from a salvage yard are an option, but their condition is unknown.
- Aftermarket Parts: This is the go-to solution. Brands like Standard Ignition (SMP) offer direct-fit replacement kits that are affordable and reliable. These kits are designed to meet or exceed the original factory specifications and provide a long service life.

Frequently Asked Questions (FAQ)
What comes in a typical 1981-1987 F-700 door lock kit?
A standard kit includes two new door lock cylinders (one for each door), two matching keys, and the retaining clips required for installation. Some kits may also include the ignition cylinder so one key works for both the doors and starting the truck.
Is replacing the door lock cylinder difficult?
No, it is considered an easy repair. The process involves removing the interior door panel, releasing a small clip that holds the cylinder in place, disconnecting the lock rod, and swapping in the new cylinder. Basic hand tools are all that's required.
Are there any recalls or technical bulletins for F-700 door locks?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database and for Technical Service Bulletins (TSBs) show no specific recalls or bulletins for the door lock cylinders on the 1981-1987 Ford F-700. Recalls for Ford door latches primarily affect much newer models.
Can I use my old key with the new lock?
No. The new lock cylinders are keyed to match the new keys that come in the kit. You cannot re-key these simple aftermarket cylinders to your old key. You will have a separate key for your doors and ignition unless you buy a matched set.
