When I use my key and not the remote keyfob to unlock the driver's door on my TJ the alarm goes off. Someone mentioned to me here in the forum that the wire connector to the BEM from the door lock has probably fallen off and to remove the door skin to get to it to fix it. How long would that take to fix? Is it a hard job? Thanks in advance.

door trim, the door skin is the outer metal part of the door.

How long would that take to fix? Is it a hard job?

Depends:
Yes, very hard and time consuming if you have never done it before.
No, easy and quick job if you have previous experience with it.

Search this forum and you will find the details on how-to.

Thanks TJ...I get the terms muddled at times. MM...thanks as well. I'll have to put the job in the too hard basket for now.
