Door Lock Issues!!!

Recently replaced the driver door on a Toyota Matrix. Now everytime i open a door the back latch just keeps unlocking repeatedly even though it is unlocked. I also can't unlock doors using the switch on the driver door. Can anyone help me?

Definitely electrical issue here - the problem is where to start.

You mentioned you replaced the door - where did you source the door, and do you still have your original one? What model year Matrix is your car? Factory / aftermarket alarm or keyless entry system?

Could be anything from a pinched/crushed wire from the installation, to a faulty switch in the replacement door.

Have you tried to reset the ECM / factory keyless system to see if it is a body logic issue, sometimes a repair like this will cause all sorts of weird stuff happening. Resetting the ECM / keyless system "fixes" many of these issues. Sort of like rebooting a computer.
