hey guys, this past week ive been noticing that the transmitter on key has been acting funky. i often have to press unlock over 10 times before the light on my key lights up and the car unlocks. im assuming that the little battery in the transmitter is dead. anyhow, if i take that battery out and replace it with a new one, will i lose the programming on the key? also, will it effect the immobilizer on the car? i dont want to open it up yet untill i find out. i did a search and could not find a single thread on any of this. i know theres a few people on here that have painted and midded their keys in different ways. any help would be appreciated!!
