If you are having troubles with your front door lock and it needs to be replaced, this article will take you through the process step by step. To begin you will need to remove the door panel and exterior door handle. Please see our articles on removing your front door panel and exterior door handle, complete the work there before starting this project. The inner door panel has the door lock assembly along with the window regulator attached to it. If the door has been worked on before there is a good chance the shop drilled out the plastic rivets for the lock assembly and never replaced them, if that is the case you will still need to remove the inner panel but you will want to wait until the panel is off before removing the two 8mm 12 point bolts from the lock or it will fall into the door cavity.

This photo illustrates the door with the door panel off.

The first thing you want to check is the upper left corner.
Figure 2

The first thing you want to check is the upper left corner. If there are two plastic rivets then the door lock assembly is attached to the panel that the regulator is attached too. You will need to remove the exterior door handle (there is a small cable attached to the assembly that you can only get at with the exterior door handle removed). Please see our articles on removing the exterior door handle for help.

The motor on our window regulator was not functioning so we had no way to raise or lower the window to get it in position to remove the window clips.
Figure 3

The motor on our window regulator was not functioning so we had no way to raise or lower the window to get it in position to remove the window clips. If you remove the motor first you can easily pull or push the window up or down with your hands. To remove the motor remove the three T30 Torx screws on the motor (red arrows). There is a wiring harness on the back of the motor that is easier to remove once the motor is off the door panel.

With the motor off turn it over and raise the lock bar (red arrow) on the wiring harness connection.

Pull the tap up (red arrow) and slide the harness off.

There are two circular access holes to the window clips, use a screwdriver and pop them open (red arrow).

With both ports open slide the window up or down until you can see both window clips in the openings (red arrows).
Figure 7

With both ports open slide the window up or down until you can see both window clips in the openings (red arrows). Securely tape the window fixed in this position.

Use a T30 Torx and completely remove the two bolts (one in each clip, red arrow).

Use a T30 Torx and completely remove the two bolts (one in each clip, red arrow). Then pull the window either all the way up and re-tape in place or remove the glass by tilting it forward and removing it from the door.

Unplug the connection from the speaker by squeezing in the two clips (red arrows) and pulling straight out.

There are a series of clips (red arrows) holding the wiring harness to the panel.

Use your trim removal tool and gently remove these clips (red arrow) so you can reinstall them when you put everything back together.

After removing the exterior door handle and the cable attached to it remove the two bolts holding the lock assembly to the door (red arrows).
Figure 12

After removing the exterior door handle and the cable attached to it remove the two bolts holding the lock assembly to the door (red arrows). On our car they where 8mm triple squares but your door may be different. Only remove these if the lock is still attached to the inner panel otherwise wait until the panel is removed and then remove the bolts.

Remove the eleven 10mm bolts from the door panel (red arrows).

Release the small snap clip (yellow arrow) to fee the lock from the bracket.
Figure 18

Release the small snap clip (yellow arrow) to fee the lock from the bracket. This way the bracket mounts (purple arrows) and the two grommets (blue arrows) and cables can remain installed in the inner door panel. You will still need to remove the door pull lock (red arrow) and the inner pull cable (green arrow).

Remove the inner pull cable (red arrow) from the lock bracket (green arrow).
