I usually jack up the car and use a pair of jumper cables. Connect the red cable to the starter lead that the battery cable attaches to and the black cable to any good body ground. Connect the other ends of the jumper cables to a good hot battery. Use jack stands for saftey reasons. Be careful and good luck. It always works for me.

SOURCE: dead battery

The solenoid is holding the power locks down. Go to the passenger door and use the key while holding up the door handle. You'll have to turn the key pretty hard to manually raise the lock.

Connect jumper cables to the starter connection which should be visible under the car, hot to the bolted battery cable connection, negative to any ground. Connect the other end to a battery after you have crawled out from under the car.  Also consider; my BMW had the battery in the trunk, which should open with a key.

Bad starter


Hey there, I have a BMW 750il just like yours, the best way is to go from the bottom, you will have more elbow room to work with.
