Question about 1994 BMW 3 Series
I have a 1994 740i, the battery is dead and I can not unlock the doors with the key, I can do so with the trunk, but not the doors. Your assistance will be very much appreciated.
If you have a jack and a battery charger, you can charge the battery from the starter wire. Connect the positive to the red wire on the starter, MAKE SURE IT'S THE STARTER WIRE AND NOT THE STARTER SOLENOID. You can connect the negative wire to ant ground on the frame. That should get some power back to your battery enough for the remote key to unlock the doors. Good luck and hope this helps. Keep me posted. Glad to know your got in your car.
