Question about 1994 BMW 7 Series
I locked my doors when I arrived at the store. When I was leaving I tried to unlock my door and the lock wouldn't budge on either side. It opened my trunk, so i had my friend reach through and unlock my back driver side. Even inside I couldn't pull the pin up, or pull the handle on either front door. I tried to start it , but it wouldn't turn over. Until now it has ran and started fine. Your advise is appreciated. Thank You.
Open the trunk. Take out the trunk lid light - take the bulb out of the fixture. Place a 12 volt battery in the trunk. Take an alligator clip jumper wire - connect one end to the negative terminal of the battery and the other end of the jumper wire to the car chassis - make sure it is a good connection and is not on a painted surface - I place mine on a bolt on the rear light panel. Take another alligator clip jumper wire and connect one end to the 12 volt positive terminal and connect the other end to the short end of the light connectors (there are two connectors for the light - one is short and one is long). This should give you enough voltage to unlock the doors. I had to figure this out and have used it twice on my BMW.

The built in security system reads a code through the key and key fob. The computer has some how lost the memory of that code and will not let it start. It will need to go to the dealer ship to be reset or reprogramed.
