Hi Everyone. Thanks in advance.

My 2007 Mitsubishi Endeavor key fob has been acting weird. It now only unlocks the driver door. Even so, when I open the door the alarm goes off until I push a button on the key fob again.

I have to unlock all other doors from the inside. I can push the "unlock" fob button a million times and it doesn't do anything different.

I unlocked it manually using the key, but it still sounded the alarm.

Any ideas?

Thanks

UPDATE:
It's been a long time since I posted this, and thought I posted the solution. But, if my memory serves me correctly, there were broken wires in the door. When I removed the driver door interior panel and the boot, I was able to look at the wires that went from the car into the door. I think 3 of the wires were completely severed and one was partially. After repairing the wires, the problem was fixed.
