Chrysler Imperial Door Lock Kit Guide: 1965-1984
Restore security and function to your classic Imperial with a new door lock kit.
- Door lock failure on a classic Imperial is typically a mechanical issue of wear or seizure; it is not electronic.
- New OEM parts are unavailable; high-quality aftermarket kits from brands like Standard Ignition are the go-to solution.
- Replacement is a straightforward DIY job, but you will need a locksmith to re-key the new locks to match your ignition key.
- Before replacement, try cleaning and lubricating the existing lock mechanism, as this can often solve sticking issues.
Understanding Door Lock Failure in Your Classic Imperial
If you're having trouble with the door locks on your 1965-1984 Chrysler Imperial, you're not alone. After decades of use, the original mechanical lock cylinders are prone to wear and tear. The most common issue is a seized or sticking mechanism due to accumulated dirt, grime, and dried-up lubricant. This can make the key hard to insert or turn, or prevent the lock from engaging or disengaging altogether. In some cases, the internal linkage connecting the lock cylinder to the latch can become disconnected or break.
Choosing the Right Aftermarket Door Lock Kit
For a vehicle of this vintage, finding New Old Stock (NOS) or new OEM door locks is nearly impossible. The market is well-served by aftermarket manufacturers who produce direct-fit replacements.
Brand Focus: Standard Ignition
Standard Ignition (also known as Standard Motor Products) is a well-regarded brand in the aftermarket industry with a long history. Their door lock kits for the Imperial are designed to be a direct replacement for the original factory parts. These kits typically include new lock cylinders made from die-cast zinc, solid brass tumblers, and two new chrome-plated brass keys. Owner reviews for Standard lock products are generally positive, citing good quality and fit. This makes them a reliable choice for restoring your door lock function.
Pro Tip: Matching Your Keys
Aftermarket door lock kits come with their own set of keys. This means your new door key will not match your original ignition key. For convenience, many owners take the new lock cylinders to a local locksmith before installation. A locksmith can re-key the new cylinders to match your existing ignition key, allowing you to continue using a single key for your entire vehicle.
Estimated Replacement Costs
Replacing the door lock cylinders is an affordable repair. The primary cost is the part itself, with labor being minimal if you do it yourself.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Door Lock Kit | $20 - $40 |
| Shop Labor | $100 - $200 |
| Locksmith Re-keying Service | $25 - $50 |
A Note on Power Locks
If your Imperial is equipped with optional power door locks, a failed lock cylinder will not be the cause of an electrical issue. Power lock problems are typically caused by faulty solenoids, switches, or wiring. If your locks don't work using the power switch but the key works manually (or is stuck), the lock cylinder is likely the problem. If the key works fine but the power function doesn't, you may need to diagnose the electrical system.
Frequently Asked Questions
Are there any recalls for 1965-1984 Imperial door locks?
No, extensive searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or technical service bulletins (TSBs) related to the door lock cylinders for the 1965-1984 Chrysler Imperial. Issues found for Chrysler vehicles relate to much newer models with different lock systems.
Can I replace just one door lock?
Yes, but kits are typically sold with a pair of locks to ensure the keys match for both doors. Replacing them in pairs is recommended for convenience and to ensure consistent feel and performance.
Is replacing the door lock cylinder a difficult job?
For a mechanically inclined owner, this is a very feasible DIY project. The process involves removing the inner door panel to access the back of the lock. The cylinder is usually held in place with a simple spring clip that can be removed with a screwdriver. The entire process for one door can typically be completed in under an hour.
What should I try before replacing the lock?
If your lock is just sticky or hard to turn, you can first try spraying a lubricant like graphite lock lube or WD-40 directly into the keyhole and onto the latch mechanism inside the door. Work the key in and out of the lock several times to spread the lubricant. This can often free up a sticking mechanism and restore function without needing a full replacement.
