    PUT THE KEY IN THE PASSENGER DOOR, TURN THE KEY AND LIFT THE HANDLE AT THE SAME TIME. THIS ONLY WORKS ON THE PASSENGER DOOR, IT WILL NOT WORK ON THE DRIVER'S DOOR.

    Had same problem with my 94 740i. If battery is completely dead the manual key operation does not work. Even a professional locksmith could not get in. BMW dealer was not very helpful either, they told me to tow it to the dealer. SO, jack up the front of the car, remove the panel under the right side to access the starter and connect a jumper cable to the Battery side of the starter. This will give you enough power to unlock the doors. Took all of about 15 minutes after I decided to try it. Good luck

    first thing i tried was the key in the passenger door. for some reason it didnt work. i then tried to find out how to access the starter this led me to a website- www.bimmerfest.com . this site although awesome (cant describe how awesome this site is for bmw owners) i didnt find the info i was looking for. i ended up opening the trunk removing the liner at the back of the trunk and knocking out a panel left partialy cut out for a factory option ski bag. i then climbed through the fairly small hole (it wasnt an enjoyable experience) popped the back seat to access the battery, snaked some battery cables through the hole connected them to my E34 540i, and voila hit the auto locks. problem solved. thanks for the info i will post this info on bimmerfest.

    Here's what I did when I had the same trouble with my '94 740i. I tried the passenger door with the key and lifting the handle, but for some reason, it seems as if the mechanism was worn out and that didn't work. Fortunately, I could open the trunk and lower the armrest and have a small child enter the car that way! But, he still could not pull up the door locks! They are "locked" in place somehow. But, the boy was able to open the hood so that I could hook up jumpers and unlock the doors!
