Just wondering if anyone else has this problem: on cold mornings, my remote entry (also windows & sunroof) doesn't work. I can't lock or unlock. This is only when I keep my car outside. Keys are kept inside and are warm. Either the battery in the keys is getting low -- I use the windows & sunroof remote often -- or there is something on the car that doesn't work well when cold. When it's warm out, everything works fine?

Any ideas?

Also, how do you change the key's battery?

 

>>Also, how do you change the key's battery?

I believe that it charges throught the ignition. Whenever you are driving your car, your key is charging.

 

Thanks, didn't realize that. Pretty cool actually. Still doesn't explain the cold problems.
