1. Gather Tools and Parts:
* New lock cylinder: Ensure you get the correct one for your 1987 Honda Accord's driver's side door. The passenger side and rear cylinders might be different. You'll likely need the VIN number to ensure compatibility. A reputable auto parts store can help.
* Small flathead screwdriver: For prying and potentially adjusting clips.
* Phillips head screwdriver: Possibly needed for interior panel removal.
* Needle-nose pliers: For manipulating small parts.
* Possibly a lock cylinder installation tool: This specialized tool can help align the cylinder for easier installation, but might not be strictly necessary.
2. Door Panel Removal:
* Consult a repair manual: This step is crucial. The process varies slightly between models and trim levels. You'll need to remove the interior door panel to access the lock mechanism. This usually involves removing screws, possibly clips, and potentially unhooking some wiring harnesses carefully. Force can damage the panel.
3. Accessing the Lock Cylinder:
* Once the door panel is removed, you'll see the lock mechanism itself. The lock cylinder is usually held in place by retaining clips or screws. The repair manual will show you exactly how it's secured.
4. Removing the Old Lock Cylinder:
* Carefully remove the retaining clips or screws. Be mindful of the small parts – you don't want to lose them.
* The cylinder itself might have a retaining clip or a small screw holding it in place within the lock mechanism. Remove this as well.
* Gently pull the old cylinder out. Take note of its orientation and any shims or spacers.
5. Installing the New Lock Cylinder:
* Insert the new lock cylinder, making sure to align it correctly with the lock mechanism.
* Replace any retaining clips or screws securely.
* Reinstall any shims or spacers in the same positions as they were on the old cylinder. Their placement is critical for correct operation.
* Test the cylinder's operation: Make sure the key turns smoothly in both directions.
6. Reassembling the Door:
* Carefully reinstall the interior door panel, making sure all clips and screws are properly secured.
* Test all functions of the door, including the lock, window, and any other features.
Important Considerations:
* Repair Manual: A 1987 Honda Accord repair manual is highly recommended. It will have detailed diagrams and instructions specific to your vehicle's make, model, and year.
* Key Matching: If you're replacing the lock cylinder, you'll likely want new keys that match. You may need to get this done by a locksmith or at a dealership.
* Professional Help: If you're not comfortable with automotive repair, consider taking it to a qualified mechanic. Improper installation can lead to problems.
This is a simplified overview. Without a repair manual specific to your 1987 Honda Accord, you risk damaging your vehicle. Always prioritize safety and consult a professional if you're unsure about any step.
