I have a 2008 GXP. I have a GM dealership programmed key fob. All door locks are functional locking and unlocking. However I am running into an issue: Normally I click my unlock button on the fob once and the drivers door unlocks, click it twice and the other three doors unlock. Additionally, normally when I put the car in gear all the doors lock and when I put the car in park all the doors unlock.But recently a problem has arisen. When I click the fob once the drivers door doesn't unlock, Click it twice and ALL the other doors unlock but NOT the drivers. When I put the car in gear all the door lock properly But when I park the drivers doesn't unlock, all the others do. Is this some sorta electrical issue or is the car telling me its time to change the fobs battery? Thanks in advance for any advice.
