Key fob issues
Hi everyone,
For some reason sometimes but more often now I been having problems with the key fob not working and killing the batteries fast. When I bought the car I changed the battery every 8 months or so now it barely last a month before I have to change it again. Now I changed the battery 2 weeks ago and it order for the key to work I have to take out the battery and put it back in so I can unlock my car. A couple hours later I can unlock the my car without any issues and it would be fine for a couple of days. But it's weird that everytime I put a brand new battery works fine for the first 2 weeks.So now I believe it's not the battery so I'm wondering if anyone else had this problem and got it fixed.

Do you have a second key? If these issues don't exist in that second key then it's the first key :B
Also, how close do you leave the keys to your car? If your car has key-less go it might be communicating with the key constantly if it's too close.

When was the last time you were at the dealer? I think there's some thread that mentions a TSB and I seem to recall there was one where there was some update that was needed to fix that problem.

I do have a second key which I have been using since yesterday because they other key stopped working. I did read that before about the key being too close to the car but My keys are usually 20 to 30 feet away from my car when I'm home so I really doubt my key would still communicate with my car being that far away.

I would also try leaving the battery out of the key for a while and see if anything changes.

do the prongs inside that touch the battery make a good connection? Might need to bend them up just a muff hair to make better contact.....just an idea and I wanted to say muff hair too........GL
