Car battery is dead and cannot open doors! Please Help!
 
Hi,

I have a 1999 540i and left the lights on for one night. The battery is only a few months old but I cannot unlock the doors using the remote or by manually keying into the drivers door. I can open the trunk but I don't think the back seats fold down from the trunk.

I need to open the car in order to open the hood and then charge the battery, if there are any suggestions besides calling AAA it would be greatly appreciated! Thanks for any help!

The battery is in the trunk, use your key to manually open the trunk. Good luck!

To unlock the door you just need to insert the key and turn a full 90 degrees counterclockwise. The manual operation can be very stiff if it has never been used or lubricated.

These threads are starting to give me a laugh.

I had that problem recently, had to force it a bit to get the manual door unlocking to work.

I think it was Saint Q who remarked at one of these threads that we're so used to pushing the button on the key fob that we don't think about the fact that we used to open car doors with the key all the time, way back when.

Anyway, to the OP, you're not the first person (nor the last) to ask this question:
- How to open the hood (1) or trunk manually when you have a dead 12v car battery (1) (2) (3) & how to unlock the older E39 if the key is locked inside the trunk (1) (2)

These threads have been beating to death haha!

OK, if you turn the key manually and the door does not open, then your door tumbler is frozen from years of non-use.

Anyway, the quickest way to solve the problem is:
- Jack the Left Front up (no need to remove the wheel), support with jackstand for safety.
Or rest the wheel down on a wood ramps etc.
- Under the car is the starter motor. Look for the RED cable feeding the starter motor.
- Connect Red to Red (from donor battery)
- Ground is ground.
- Then hit the remote. You will likely need an assistant for this job.

The location of the Red terminal is at the same area as the aft part of the tire. Locate the aft part of the tire and move inward, you will see it:
