Hello 2CarPros, we have the car listed above. When we push the button on the car key remote to unlock the doors, the doors will unlock but they will lock again even before you can open the door. I have no idea what to do or even what to look for to fix this problem. I am enclosing pictures of our key remote. Sure need some help, please, Sincerely, Bill Hewitt

Hello Bill,

This can be the BCM, instrument cluster, remote control lock receiver or a bad fuse #BCM 2, 3, 4, and 5. So let's check the fuses first here is a guide to help and the fuse locations in the images below I have also included the wiring diagrams for the lock system so you can see how it works.

If all of the fuses are good, we should do a CAN scan, you can get a CAN scanner (Controller Area Network) from Amazon.

Here is a video to show you how:

Here is a list of CAN scanners starting at about $25.00 on Amazon:

It sounds like to me that the BCM is out which you can get a preprogrammed unit by searching Google or Ebay. I have also included the location of the BCM and how to replace it as well. Check out the images (below). Please let us know what happens.

Hello Ken, sorry I have not gotten back to you sooner. The first thing that I did was to take a look at the electric switches on the door panel. The first thing I noticed was that the lock door switch was in the lock position. I tried to push the switch to the unlock position, but it didn’t want to move. I kept pushing on the switch until it finally moved to the unlock position, that is where I left it. I then tried the key remote to lock and unlock the car doors, now the car door locks are working fine. My guess, is that the lock/unlock switch is going bad. What do you think? Sincerely, Bill Hewitt
