Is Your Buick Regal's Door Lock Failing?
After decades of service, the door locks on a classic G-Body like the 1979-1988 Buick Regal are bound to show their age. You might notice the key feels gritty, is hard to turn, or maybe doesn't work at all. This isn't just an inconvenience; it's a security issue. These problems are usually caused by worn internal tumblers, dirt inside the lock, or a failing retaining clip. Fortunately, replacing the door lock cylinders is a straightforward job that restores both function and peace of mind.
Choosing the Right Aftermarket Door Lock Kit
For a vehicle of this era, new OEM parts from GM are generally not available. The aftermarket offers reliable solutions that meet or exceed original standards. The two main brands you'll encounter are ACDelco and Standard Ignition (Standard Motor Products).
- ACDelco: As GM's official parts brand, ACDelco is often considered the top-tier choice for aftermarket parts. Their products are designed to meet original equipment specifications, offering a fit and finish that is very close to the factory part. While they may sometimes re-brand parts from other manufacturers, their quality control is generally trusted by professional mechanics.
- Standard Ignition (SMP): Standard is a highly respected aftermarket manufacturer with a long history of producing quality electrical and mechanical parts. Their components are known for reliability and are a trusted choice for daily drivers and restoration projects alike. For a part like a door lock cylinder, a Standard kit is a dependable and cost-effective option.
For this specific part, both ACDelco and Standard Ignition provide quality replacements. The difference in daily use will likely be negligible. Your choice can confidently be based on price and availability.

Frequently Asked Questions
Do I have to replace both door locks at the same time?
It's highly recommended. Aftermarket door lock kits come with a matching pair of cylinders and keys. Replacing both ensures you can use a single new key for both doors, which is much more convenient than carrying multiple keys for the same car.
Can I make the new door locks work with my original ignition key?
Yes. A professional locksmith can re-key the new lock cylinders to match your existing key. This involves rearranging the small pins (or wafers) inside the new cylinder to match the pattern of your old key. This is a great option if you want to maintain a single key for the doors and ignition.
Is this different for cars with power locks?
No, the lock cylinder replacement is the same. The door lock kit replaces the mechanical key cylinder. The power lock system uses an electric solenoid (actuator) to move the lock rods, which is a separate component. If your key isn't working but the power lock button does, the cylinder is the likely problem. If the button doesn't work, you may have an issue with the actuator or switch.
What tools are needed for the replacement?
You will need basic hand tools like a screwdriver set and a socket set to remove the door panel. A pair of pliers is also helpful for removing the retaining clip that holds the lock cylinder in place. The job does not require specialized tools and is considered DIY-friendly.
Are there any recalls for the door locks on my 1979-1988 Regal?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no specific recalls for the door lock cylinders or latches on the 1979-1988 Buick Regal. Any recalls found are for much newer models or different components.
