1997 Oldsmobile Regency Trunk Lock and Cylinder Guide
Struggling with a trunk that won't open or stay shut? This guide explains how to diagnose and fix the problem.
- For the 1997 Regency, an aftermarket lock cylinder from a reputable brand like Standard Ignition is the most practical replacement option.
- Diagnose the problem carefully: if the key won't turn, you need a lock cylinder; if the power button fails but the key works, you need an actuator.
- Replacement of the lock cylinder is a simple DIY task for most owners, requiring basic hand tools and about 30 minutes.
- No recalls have been issued for the trunk latch or lock system on this vehicle.
Is Your Trunk Lock Failing? Key Symptoms for the 1997 Regency
Due to the age of the vehicle, problems with the trunk lock are not uncommon. It's important to identify the specific symptom you're having, as it will point to which part has failed. This will help you buy the right component for the repair.
- Trunk Won't Latch Closed: If the trunk lid pops back up when you try to close it, the latch mechanism is likely jammed or broken. It isn't catching the striker properly, which leaves your trunk unsecured.
- Key Won't Turn or Feels Stuck: When the key is hard to turn or won't work in the lock, the issue is with the mechanical lock cylinder itself. The internal tumblers may be worn out or seized.
- Clicking Sound, But Trunk Stays Shut: If you press the interior release button and hear a click from the trunk area but it doesn't open, the electric actuator is the likely culprit. It has grown too weak to pull the release lever on the latch. A forum user with a '97 Oldsmobile LSS noted this exact issue.
- Remote/Button Fails, But Key Works: This symptom clearly separates an electrical problem from a mechanical one. If the key opens the trunk but the power release does not, the problem lies within the electrical actuator, its wiring, or the relay.
Distinguishing the "Lock" from the "Latch"
When shopping for parts, it's crucial to know what you need. The Trunk Lock Cylinder is the part your key goes into. The Trunk Latch/Actuator is the electronic and mechanical assembly inside the trunk lid that does the actual locking and unlocking. The parts available from Standard Ignition in the $14-$23 price range are typically lock cylinders that come with a new set of keys.
Choosing the Right Aftermarket Trunk Lock
For a 1997 vehicle, finding a new original equipment manufacturer (OEM) trunk lock from GM is highly unlikely. The most practical and available option is a new aftermarket part.
Standard Ignition (Standard Motor Products) is a well-regarded brand in the aftermarket industry with over a century of experience. They are known for producing quality replacement parts like lock cylinders that meet or exceed original specifications, using durable materials like brass tumblers and die-cast zinc cores. For a component like a trunk lock cylinder on the Regency, Standard Ignition offers a reliable and affordable solution.
Cost of Replacing a 1997 Oldsmobile Regency Trunk Lock
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Lock Cylinder | $14.90 - $23.31 |
| New OEM Lock Cylinder | Likely Unavailable |
| Used OEM (Junkyard) | $15 - $40 |

Pro Tip: If your lock cylinder is simply stiff but still functional, you can try lubricating it. A silicone or gel-based lubricant can sometimes free up sticking internal components and restore smooth operation.
Frequently Asked Questions (FAQ)
Can I replace the trunk lock cylinder myself?
Yes, this is a straightforward DIY job for most owners. The process typically involves removing the trunk lid's inner trim panel, detaching a retaining clip that holds the cylinder in place, and disconnecting the rod that links it to the latch mechanism. You then install the new cylinder and reconnect everything.
Will a new aftermarket lock cylinder work with my original car keys?
No. An aftermarket trunk lock cylinder will come with its own new set of keys. You will need to use this new key for the trunk, while your original key will continue to work for the doors and ignition.
My trunk is stuck shut. How can I open it to make the repair?
If both the key and the electronic release have failed, you will likely need to access the trunk from inside the car. This involves folding down or removing the rear seat back to gain access to the trunk cavity. From there, you can typically find the emergency release handle or manually operate the latch mechanism to open the lid.
Are there any recalls for the 1997 Regency trunk lock?
No, there have been no recalls issued by the NHTSA for the trunk lock or latch mechanism on the 1997 Oldsmobile Regency.
