How to Convert Car Door Locks to Power Locks
Although it is very rare these days to buy a car which has manual car door locks, you may have a used car that you desire to spruce up. While you may have a little respect for the simplicity of the manual car door locks, they are no competition for their more sophisticated cousin, the power lock. Fortunately, you can buy kits which will allow you to change your manual lock into a power lock in only a few hours. This is done easily enough, and you should be able to manage it without any kind of problem, so long as you follow a few basic guidelines.
Step 1 - Take Off the Door Handle
You will have to remove the accessories from the inside of the door, such as the internal door handle, and the window crank. You will probably need a specialist tool for this. You could find this kind of tool at your local car shop. Check your car manual before buying this tool, as you may be able to lever it off with a screwdriver. Once you have these pieces off, you should then take off the door panel using your special tool. Place the panel to one side.
Step 2 - Take Off the Manual Locks
With your screwdriver, remove the manual lock from its position. You may need to remove parts of the inside of the door in order to get to the lock, but you should be able to remove it with simple unscrewing. Take out the manual lock, and then look at the mounting pads for your actuator. Using your pliers, bend your lock rod from the kit, and make this so that it runs along the same line as the factory lock connection. You can then fit the manual lock back into the door, synchronizing the actuator and the lock rod. Connect the lock connector from your kit to the actuator. Make sure that everything is fastened into place.
Step 3 - Install the Locking Module
You need to wire the central locking module to a hot circuit (this is one which is constantly running power) such as the dashboard. Screw the module into position in the location. Use your pliers to connect the module to the circuit, and then place the wiring below the carpet until it reaches the door jamb. Connect each lock (one for each door) to the wires, and then plug these into the locking module. When you press the key, you should automatically turn the locks. Keep repeating the test until you have the wiring correct for this item.
