BMW 7-Series Maintenance and Repair
I was out for half year, and I dis-connect the battery for my 97 740il. I came back over the weekend, and I was able to start the car after I put the battery back on.
Here is the problem: at the early begining, I couldn't lock/unlock the car/truck by using the car key. So that I have to do it manually. And then two days later, all a sudden, it works fine! I can lock/unlock the car by using the car key.
And now I still have another problem on the trunk. If I want to unlock the trunk, then I have to RE-LOCK the car again, and use the key to unlock the trunk manually. I remember back to the old days, if the car doors were unlock, then I can go ahead to push the trunk key-hole, and the trunk will be unlocked.
Does anyone know how to fix it? I called dealer, and they said it will cost me $79.99 to reset. And this is too pricy. Thank you in advance.
