I went to the BMW dealer 2 days ago. A mechanic I saw there said to reprogram it before buying a new key. I told him I tried. He went in my car put the key in the ignition and did some magical stuff!
1 day later, yesterday, my damn key stopped working again, this time it will lock but not unlock. Called the guy I know at BMW, told him il just buy a new key, he told me it might not be the key the problem, and it might be a problem with the mechanism that unlocks the car.
So now I do not know what to do, buy a new key and hope it works, or change the door lock???? Damn this gets confusing!!!!!
