A Practical Guide to the 1962-1968 Chevrolet Chevy II Trunk Lock
Solve common trunk lock problems and get your classic Chevy II or Nova's trunk secure again.
- Aftermarket trunk locks are a reliable and affordable solution for the 1962-1968 Chevy II.
- Installation is very easy if the trunk is already open, requiring only the removal of a single clip.
- A new lock will come with a new set of keys; your old keys will not work.
- For convenience, consider buying a complete set that includes door locks so one key opens everything.
Signs of a Failing Trunk Lock
On a classic car like the Chevy II, trunk lock failures are straightforward and mechanical. Years of use, exposure to moisture, and general wear are the main culprits. You'll know you have a problem if you experience one or more of the following symptoms.
- Key Won't Turn: The key may go in but refuse to turn, or it might not go in at all. This is often caused by dirt, grit, or corrosion inside the lock cylinder.
- Stiff Operation: If you need to jiggle the key or use force to get the lock to turn, the internal tumblers are likely worn or gummed up.
- No Resistance: Turning the key feels loose and does nothing. This almost always means a mechanical part has broken, either inside the lock cylinder or the connecting shaft to the latch.
- Trunk Won't Latch: If the trunk lid pops back up after you close it, the issue is likely with the latch mechanism itself, not the lock cylinder. The latch could be misaligned or worn out.
Choosing the Right Aftermarket Trunk Lock
For the 1962-1968 Chevy II, original OEM trunk locks from Chevrolet are no longer in production. The market consists of New Old Stock (NOS) parts, which are rare and expensive, and aftermarket reproductions. For a simple mechanical part like this, a quality aftermarket lock is a reliable and cost-effective solution. Your choice generally comes down to two tiers.
Economy Brands (Replacement)
These are the most budget-friendly options. A brand like Replacement offers a functional lock that will get the job done. It's a good choice for a daily driver or if budget is your primary concern. These kits typically include the lock cylinder, two keys, a gasket, and the retaining clip.
Premium Aftermarket Brands (Standard Ignition)
Brands like Standard Ignition (also known as Standard Motor Products) are known for producing parts that meet or exceed original specifications. They often use higher-grade materials and may offer a more precise fit and finish, closer to the original part. This is a great option if you are doing a more detailed restoration or simply want the most durable part available.
Pro Tip: Consider a Full Lock Set
From the factory, the trunk key was different from the ignition and door key. Many aftermarket suppliers offer kits that include the trunk lock and both door locks, all keyed to work with the same key. This is a convenient upgrade if you are replacing the trunk lock anyway.

Frequently Asked Questions
Is it difficult to replace the trunk lock?
No, it is a very simple job if your trunk can be opened. You just need to remove a horseshoe-shaped clip from the back of the lock cylinder inside the trunk, and the old lock will pull out. The new one slides in and is secured with the new clip provided in the kit. The entire process takes less than 30 minutes with basic hand tools.
What if my trunk is stuck closed?
If the lock is completely seized and you cannot open the trunk, you have two options. The first is to remove the rear seat back to gain access to the trunk, then use a long tool to unbolt the latch mechanism from the trunk floor. The second, more destructive option is to drill out the center of the lock cylinder, which will destroy it but allow you to turn the mechanism with a screwdriver.
Will the new lock use my original keys?
No. A new aftermarket trunk lock will come with its own set of two keys. If you want to use your original keys, you would need to take the new lock and your old keys to a locksmith to have the new cylinder re-keyed, if the lock design allows it.
Do I need to replace the latch mechanism too?
Not usually. The lock cylinder and the latch are separate parts. Only replace the latch if the trunk lid is not staying closed or if the latch itself is visibly broken or rusted. The latch mechanism is a robust part shared with many other GM vehicles of the era.
