How do i unlock a 98 bmw 740i when battery is dead

I found two things

First says insert key and turn solidly 90 degrees. Some say this doesn't work as even the key actuated a electronics servo.

Second states this which appears to be the best answer.

I have a 92 525i and the manual says this:

The passenger door, pull out the handle first then insert the key and turn.

1994 BMW 740i I haven't started in months. battery dead. I can open the trunk but not the doors to jump. Any suggestions?

raise and support the car. slide under and hook up a jumper cable to the POsitive on the starter. hook the other end to a good battery or charger. hook up a negative cable to chassis ground and to the battery/cable. Now you have power to the entire car.

The battery for your car is under the back seat on the pass. side. Unlock the car with the key and manually unlock the doors from the inside. Pull the back seat up to unsnap it from the clips on the floor.

Locked out of car

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.

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.

Put the key in the driver's door and while lifting up, turn the key. You may need to jiggle the handle and key a little but it should open.

Cannot open doors to 1994 bmw 740 il with key. battery is dead and located under rear seat. key will open up trunk.

hi jim, try lifting up on the driver's outside door handle slowly while turning the key in the unlock position. The lock cylinder design has a cam on it that usually will catch while lifting the handle. if you have no luck on the driver's side, try the same thing on the passenger's side. be patient, it make take a few tries before the door unlocks.
