Battery For Keyless Entry Remote Keeps Dying
  First post by: www.itsbattery.com
I have a 2002 Mercury Cougar XR. When I bought this car about a year ago, everything worked just fine. Like most cars, it came with a keyless entry. The remote worked fine for about two months. Then when I noticed the doors weren't locking and unlocking with the remote, I went to Radio Shack and bought a new dell Latitude D800 battery.
As soon as I put the dell Inspiron 8500 battery in, the remote worked great! Then like two weeks later it started to die again. That didn't seem right. Sometimes it wouldn't work at all. One day it would work then the next it wouldn't.
I went to Radio Shack and bought another battery. Again, it worked just like new. A few weeks later, it was dead again. I am pretty sure your supposed to get more life out of the dell 8N544 battery in your keyless entry remote. Has anyone else have this problem? Do you think Maybe its a problem with the wiring or something?
