Since this type of key has been around for 19 years (since 9/99-2006) and was used on EIGHT different BMW models (e38/e39/e46/e52/e53/e83/e85/e86)...a simple google search will have you tripping over DIYs and videos on how to crack open this type of key...as well as the horror stories where capacitors/resistors/etc have been knocked off/damaged trying to open the key as well as the soldered traces and antenna (on the remotes internal IC board) being scratched/cut, as well. :yikes:Back to the question as anyone been successful getting key open and changing battery? Concerned aBout destroying the drive away security and making the key useless.Anyone been successful with the battery charger idea you mentioned.
I was hoping to hear experience ofsome X5 owners who changed the batteries. What to do and not and what to watch out for.
