Replacing the latch on the front door is not that difficult but you will need to first remove the door panel along with the outside door handle; so make sure you factor that into the time you give yourself to complete the job. It is a tight fit inside the door so also make sure to turn the latch in the upper section of the door for removal rather than at the bottom.

Over the years your car may have been serviced by multiple people including previous owners and this can lead to parts being replaced with different size fasteners and hardware. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches. If something is different on your vehicle please let us know and share your info to help other users. If you have any questions or comments or even a different procedure you would like to share please leave it below and please leave your vehicle information.

First park the vehicle on a flat and level surface; there is nothing worse than trying to work on a door while it keeps swinging open or closed on you. Next you will need to remove the door panel and exterior door handle so please see our articles on those procedures for additional assistance.

With the door panel off you can access the latch and the connecting rods and inner door handle (yellow arrow).

There should be small metal clips that help hold the rods in place in the latch (red arrow).

There should be small metal clips that help hold the rods in place in the latch (red arrow). Use a small flathead screwdriver and push the clip down and off the rods.

Remove the clips from the rods so you can remove the rods from the latch.
Figure 3

Remove the clips from the rods so you can remove the rods from the latch. It is a good idea to have a small telescoping magnet handy as these tend to slip and fall into the door cavity.

The inner door handle rod is bent on the end which means you will need to remove the handle to remove the rod.

With the inner handle removed you can turn it until you can slip the rod out from the mechanism (red arrow).

This will allow you to position the rod so you can remove it from the latch.

Use a Philips head screwdriver and remove the four screws holding the latch to the door (red arrows).
Figure 8

Use a Philips head screwdriver and remove the four screws holding the latch to the door (red arrows). Once the last screw is out, the latch can fall inside the door so keep a hand on it. You are going to want to turn the latch in the upper section of the door to clear the inner door mechanicals.

Once you have turned the latch you can remove it out through the bottom of the door.

Once you have turned the latch you can remove it out through the bottom of the door. Installation is the reverse of removal.
