2018 BMW 540i Battery Dead, Can't Open Doors

[2ButterScotch2]

The car sat undriven for over a month and now fob will not unlike the doors. What is the best way to access vehicle and charge battery?

[MarcoZandrini]

Doesn’t the drivers door have a key lock? Open the door using the key, pop the hood and use the jumper post located under the red plastic cover as the positive and the uncovered ground jumper post as the negative. If there’s no ground post use the engine for ground.

Correct. Remove the cover on the driver door handle and insert the blade key to unlock and open the door.
