What the LOCK?!?!?!

[asuX5]

Hey all! I'm sure this was covered but I couldn't find it. Someone else recently posted about a similar issue but I was looking for a more specific answer. Lately, my central locking has been acting up. What happens is when I unlock with the remote when I press the fob a second time only the passenger door unlocks. After several attempts the rear door unlocks. Sometimes even from the inside it doesn't unlock. This has been happening more frequently with the cold we have been having but I also have been using my X more since my E30 front suspension went. Any help would be greatly appreciated! Thanks for your time!

I had this problem on my 4.8is as well. It has to do with voltage. At least in my case. From your picture, I am assuming you have a 04-06 4.4. When I would unlock, the drivers would unlock, hit the button again, just the front pass would unlock, but not the rear. Even the central button in the center console wouldn't work. Cycle it a few times and then it unlocks. I bet if it happens, you can hear the actuator working the rear doors. But when it is about to happen, you don't hear the click.

After hooking up my car to GT-1, I found out I was getting inconsistant voltage. I changed out the Voltage reg... the problem has never come back.
