- Standard Ignition is a reputable brand for this component, known for quality that meets or exceeds original standards.

Is Your Buick Skylark's Door Lock Failing?
For a classic car like the Buick Skylark, produced from 1961 to 1991, most parts that fail do so from simple wear and tear. The door lock cylinder is no exception. These are purely mechanical systems, especially on earlier models. Decades of inserting a key, exposure to weather, and general use cause the internal tumblers and springs to wear down. Eventually, the key may no longer work smoothly or at all.
Common Ordering Mistake
Door lock kits often come with new keys. Be aware that these new keys will only work for your doors. You will still need your original key for the ignition and trunk unless you purchase a complete lock set that includes all three.
Choosing the Right Aftermarket Door Lock Kit
For a vehicle as old as the 1961-1991 Skylark, finding new original equipment (OEM) parts from GM is nearly impossible. The market is almost entirely composed of aftermarket parts, used parts from salvage yards, or very rare New Old Stock (NOS). For a security component like a door lock, a new aftermarket part is the most reliable and accessible choice.
Brand Spotlight: Standard Ignition
Standard Ignition, also known as Standard Motor Products (SMP), is a well-regarded brand in the aftermarket industry with a long history of producing reliable components. They manufacture parts designed to meet or exceed the original factory specifications. Reviews for their lock cylinders are generally positive, with technicians and DIYers trusting them for good fit and function. While occasional minor adjustments might be needed with any aftermarket part on an older car, Standard is considered a quality choice for ensuring your Skylark's doors lock properly.
Pro Tip: Lubricate Before Installation
Before installing your new lock cylinder, spray a small amount of graphite lubricant into the keyhole. Work the key in and out a few times to distribute it. This ensures smooth operation from day one and helps prevent the tumblers from sticking in the future.
Known Issues, Recalls, and Service Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database and other sources show no specific recalls or Technical Service Bulletins (TSBs) for the door lock cylinders on the 1961-1991 Buick Skylark. Any problems you experience are almost certainly due to the age and wear of the original part, not a manufacturing defect.

Frequently Asked Questions (FAQ)
Do I need to replace the locks on both doors at the same time?
You don't have to, but it's often a good idea. If one lock has failed from age, the other is likely not far behind. Replacing them as a pair ensures both doors operate reliably and can often be done with a kit that uses a single key for both.
Will the new door key work in my ignition?
No. A standard door lock kit comes with keys that only match the new door cylinders. To have one key for the doors and ignition, you would need to buy a complete lock set (ignition, doors, trunk) or have a locksmith re-key the new cylinder to match your original key, if possible.
Is replacing a door lock cylinder a good DIY project?
Yes, for most people with basic tools. The process involves removing the interior door panel to access a clip that holds the lock cylinder in place. The main challenge is being careful not to break old plastic clips on the door panel. Watching a general video on door panel removal for a classic GM car can be very helpful.
What's the difference between a door lock kit and a power lock actuator?
The door lock kit is the mechanical part your key goes into. The power lock actuator is an electric motor that automatically moves the lock for you when you press a switch. If your key doesn't work but the power locks do (or vice-versa), it helps you know which part has failed. This guide focuses on the mechanical key cylinder.
Technical Specifications
Kit typically includes two door lock cylinders and a matching set of keys. Construction is usually die-cast metal with internal brass tumblers.
