I have a big problem,please help me,non of the mechanics can. Drivers door of my Audi A3 2003 (3 doors) can be locked/unlocked manually,but the remote does not work at all. I've tried to change it,reprogram and everything but it doesn't work. I can't even erase it or program it by computer,it just wont let me.

Now I've tried to put Meta System in it,hoping that it would solve my problem,because it has it's own locking system. But again-no. When I turn off the car It can be locked and unlocked with a Meta remote,but after 5 mins again problem. When I try to unlock it,Meta does its thing and turns off alarm,but the door is still locked.

And the third problem is,I can't unlock the codrivers door without turning on the car first.

This is a big problem I suppose,so pls if anyone can-help me. If you have similar,or had similar problems,pls write.
