Tools You'll Likely Need:
* Screwdrivers: Phillips and flathead, various sizes.
* Pliers: Needle-nose pliers are helpful for reaching small parts.
* Socket set: Possibly needed depending on the lock mechanism.
* Wrench: Potentially needed.
* Penetrating oil (like PB Blaster): To loosen any rusted or stuck parts.
* A helper (optional but recommended): Holding the door panel while working can be beneficial.
Steps (General Outline):
1. Interior Door Panel Removal: Carefully remove the interior door panel. This usually involves removing screws around the edges and possibly some clips or fasteners holding it in place. Be gentle to avoid breaking clips. A repair manual will show you exactly where these are located.
2. Lock Mechanism Access: Once the door panel is removed, you should see the lock mechanism. This usually involves a series of rods, linkages, and the lock cylinder itself.
3. Disconnect Linkages: Carefully disconnect the rods and linkages connected to the lock mechanism. Take photos or make sketches as you go to help with reassembly. This is where penetrating oil might be crucial if things are stuck.
4. Remove the Lock Cylinder: The lock cylinder itself is usually held in place by screws or a retaining clip. Identify how it's secured and carefully remove it. Again, penetrating oil might be necessary.
5. Remove the entire lock mechanism (if necessary): Depending on your goals (replacing the whole mechanism vs. just the cylinder), you may need to remove the entire assembly from the door. This often involves removing more screws or bolts. Refer to your repair manual for the precise location and method.
Important Considerations:
* Rust and Age: On a 1964 truck, rust and age are significant factors. Be prepared for things to be stuck or broken. Use penetrating oil liberally and proceed slowly to avoid damage.
* Repair Manual: A shop manual specific to your 1964 Chevy pickup is highly recommended. It will provide detailed diagrams and instructions, saving you time and frustration. Online resources may be helpful, but nothing beats a dedicated repair manual.
* Replacement Parts: If you're replacing the lock, make sure you have the correct replacement parts for your specific truck model.
Safety Note: Always disconnect the battery's negative terminal before working on any electrical components in your vehicle. While this step isn't directly related to removing the locks, it's a good safety practice when working on any car.
This process can be challenging, and even with the instructions, you might encounter unexpected difficulties. If you are not comfortable working on your vehicle, it's best to take it to a qualified mechanic. Remember to take pictures throughout the process to assist in reassembly.
