1963-1969 Buick Riviera Ignition Lock Cylinder Replacement Guide
If your key is sticking or won't turn, this guide is for your Riviera.
- A failing ignition lock cylinder is a mechanical issue; symptoms include a key that is hard to turn or gets stuck.
- Replacement is a simple DIY job for most owners, requiring only a paperclip to release the old cylinder.
- The lock cylinder is a different part from the electrical ignition switch; if you have electrical issues, the switch may be the problem.
- New aftermarket cylinders come with a new set of keys; your original keys will no longer start the car.
Is Your Ignition Lock Cylinder Failing?
On a classic car like the 1963-1969 Buick Riviera, the ignition lock cylinder is a purely mechanical part. After decades of use, the small metal tumblers and springs inside wear out. This wear and tear is the most common cause of failure. Recognizing the symptoms early can prevent you from getting stranded.
Common Symptoms of a Bad Lock Cylinder:
- Key is Hard to Insert or Remove: You feel resistance, or the key jams when you try to put it in or pull it out. This happens as the tumblers and the key itself wear down.
- Key Won't Turn: The most common failure. The key goes in but you can't turn it to the accessory or start position. Worn tumblers fail to align properly, blocking the cylinder from rotating.
- Key Feels Loose: If the key feels sloppy or wiggles excessively in the lock, it's a sign of significant wear inside the cylinder.
- Needing to 'Jiggle' the Key: If you have to wiggle the key to get it to turn, the internal parts are worn and failing to catch properly.
Lock Cylinder vs. Ignition Switch
It's important to know the difference. The lock cylinder is the mechanical tumbler you put the key into. The ignition switch is the electronic part behind the dash that the cylinder operates. If you have electrical problems, like the radio not working or the car stalling while driving, the ignition switch or its wiring is the more likely culprit, not the lock cylinder.
Choosing the Right Aftermarket Ignition Lock Cylinder
For a 1963-1969 Riviera, finding a new original equipment (OEM) part from GM is nearly impossible.

Pro Tip: A Simple DIY Job
Replacing the lock cylinder on this Riviera is surprisingly easy and can be done in minutes with a common household item. The procedure involves turning the key to the 'Accessory' position and inserting a straightened paperclip into a small release hole on the face of the cylinder. Pushing the paperclip in releases a retaining pin, allowing you to turn the key further and pull the entire cylinder out. This makes it an excellent DIY task that can save you labor costs.
Frequently Asked Questions
Will my original keys work with the new lock cylinder?
No. New aftermarket ignition lock cylinders come as a coded set with two new keys that are matched to that specific cylinder. You will need to add the new ignition key to your keychain.
What is the difference between the ignition lock cylinder and the ignition switch?
The lock cylinder is the mechanical part in the dash where you insert your key. The ignition switch is a separate electrical component, located behind the dashboard, that the lock cylinder turns. If your car has starting problems but the key turns fine, the issue may be with the ignition switch, neutral safety switch, or wiring, not the lock cylinder.
Do I need special tools to replace the lock cylinder?
No. For most 1963-1969 Rivieras, the only tool you need is a straightened paperclip to depress the release pin on the front of the lock. No dash disassembly is required to remove the cylinder itself.
Are there any recalls for the 1963-1969 Riviera ignition?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database and other sources show no specific recalls or Technical Service Bulletins (TSBs) for the ignition lock cylinder on the 1963-1969 Buick Riviera. The well-known GM ignition recalls of the 2010s involved much newer vehicles with different ignition systems.
