Is Your LeSabre's Trunk Lock Failing?
For a car from the late 50s and early 60s, a worn-out trunk lock is a common problem. Decades of use, exposure to moisture, and simple wear and tear can cause issues. Since this is a mechanical part, the signs of failure are usually straightforward.
Symptoms of a Bad Trunk Lock
- Key is hard to insert or turn: If you feel a lot of resistance or wiggling is required, the tumblers inside the lock cylinder are likely worn or corroded.
- Trunk won't open: The key might turn, but nothing happens. This often points to a broken connection between the lock cylinder and the latch mechanism itself.
- Trunk won't stay closed: If the trunk lid pops open while driving or won't latch securely, the latch mechanism is likely worn out or damaged and can no longer hold onto the striker.
- The lock is physically loose or damaged: Rust or physical damage can cause the entire assembly to fail.

Choosing the Right Aftermarket Part
For a classic vehicle like the 1959-1963 LeSabre, you won't find new original parts from GM. Instead, you'll be choosing between New Old Stock (NOS) parts, which are rare and expensive, or new aftermarket parts. Aftermarket parts are a cost-effective and reliable solution.
Pro Tip: When ordering, you may see the lock cylinder sold separately from the trunk latch mechanism. Make sure you identify which part is broken before you buy, or consider replacing both for a complete overhaul.
- ACDelco: As GM's official parts brand, ACDelco is a trusted name. Their replacement parts are generally made to meet original specifications for quality and fit. For a part like a lock cylinder, this is a very reliable choice.
- Standard Ignition (Standard Motor Products): SMP is a well-respected aftermarket manufacturer with a long history. They produce quality components that are a dependable alternative to OEM parts, and many professional mechanics trust them.
Honestly, for a simple mechanical part like a trunk lock on this vehicle, both ACDelco and Standard Ignition offer quality products. Your choice can confidently be based on price and availability.
A Note on Keys
Your new aftermarket trunk lock will come with a new set of keys. It will not work with your original car keys. If you want all your locks to use a single key, you would need to have the new lock cylinder re-keyed by a locksmith, which may be possible depending on the lock's design.
Frequently Asked Questions
Is it difficult to replace a trunk lock on a 1959-1963 LeSabre?
No, this is a very DIY-friendly job for most people. It typically involves removing an access panel inside the trunk, unclipping the rod from the latch, and unbolting the old lock assembly. Basic hand tools are usually all that's needed.
My trunk is stuck closed. How can I get it open to replace the lock?
This is a common problem for older cars. Access is often possible by removing the rear seat back to get into the trunk. From there, you should be able to manually operate the latch mechanism with a screwdriver or pliers to open the lid.
Are there any recalls for the trunk lock on this Buick?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls for the trunk lock on the 1959-1963 Buick LeSabre. Recalls for a mechanical part on a vehicle of this age are extremely rare.
Should I use lubricant on my new trunk lock?
Yes, it's a good idea to use a small amount of graphite lubricant in the lock cylinder itself. For the latch mechanism, a light spray of white lithium grease will help ensure smooth operation and prevent rust.
