Over the past month my keyless doorlock system has beem gradually getting weaker and weaker and I had to be closer and closer to the car to get it to work.....seemed obvioous and easy fix...just put new batteries in the key fob....but put two new ones in today and it doesn't work any better.

It only works if I'm standing very close to the car and on the drivers side.

Any help as to what's wrong.
