Here's a general approach, but proceed with caution and understand you might damage your car if you're not comfortable with automotive repair:
1. Accessing the Lock Cylinder:
* Through the trunk (ideal but often difficult): This is the best-case scenario. Some Intrigues might allow access to the lock mechanism from inside the trunk itself, perhaps by removing the trunk lining or inner panel. You'll need to carefully investigate this possibility first. Look for screws or clips holding interior panels.
* Through the interior: This is often necessary. You might need to remove interior panels in the rear passenger compartment to access the lock mechanism from behind. This could involve removing side panels, seatbacks, or even parts of the rear deck. Consult a repair manual specific to your Intrigue's year.
* Through the bumper/exterior: In some cases, particularly if you've damaged the trunk mechanism, accessing the cylinder might require removal of the rear bumper or other exterior components.
2. Replacement Process (Once Access is Gained):
* Disconnect the linkage: The lock cylinder is connected to a linkage mechanism that operates the latch. You'll need to carefully disconnect this linkage before removing the cylinder.
* Remove the cylinder: The cylinder is likely held in place with retaining clips or screws. These might be visible once you gain access. Sometimes, you might need to use special tools, like a lock cylinder removal tool, to extract it safely.
* Install the new cylinder: Insert the new lock cylinder, ensuring the linkage is properly reconnected.
* Test the lock: Test the new cylinder from both the keyhole and the trunk release button (if applicable).
Critical Considerations:
* Repair Manual: A repair manual specific to your Oldsmobile Intrigue's year is absolutely essential. It will provide detailed diagrams and instructions for accessing the trunk lock mechanism. You can find these online or at auto parts stores.
* Specialized Tools: You might need specialized tools beyond common household tools.
* Professional Help: If you're not comfortable with automotive repair, consider seeking professional help from a locksmith or auto mechanic. Improperly attempting this repair can lead to further damage and increased repair costs.
* Getting the correct cylinder: Ensure you order the correct replacement trunk lock cylinder for your specific year and model Intrigue. The part number should be readily available from the vehicle's documentation or a parts store using the VIN.
Attempting this without the proper knowledge and tools risks causing more damage. If you're unsure, it's best to consult a professional.
