How do I replace the battery in my 2008 bmw 535i

SOURCE: Battery is dead. Doors are locked. Can't get into car.

I m a locksmith and had the same problem

What you do is:

HOld The handle up while you turn the key to the opening direction, it will feel as though it may bend the key but it will not.

keep pulling the handle until the button pops up it works I did it

SOURCE: 1999 bmw 528 won't start

yeh go back to Kragen and say are you taking the ****, reset button who told you that. it must be next to the kerfuffle valve. and operated by the **** behind the peddle. or the nut behind the wheel. how to start a car lesson one. heavy duty Power to the starter, and a good chassis earth generally through the engine block. a good charge in the battery. and a switched live to the low tension circuit on the solenoid of the starter motor via ignition switch/key. if all those are fine it should work.......

SOURCE: Need to replace the battery in the car key.

If it's like my 2006 Z4 key you don't replace the battery. It has an internal rechargeable battery that charges when the key is in the ignition. Not sure how to replace the battery if it won't charge.

SOURCE: Just had the battery replaced. The 2001 BMW X5 brake and abs lights are on. Is this a Battery problem, fuse or what?

my cigarette lighter doesn't work in the front or the back...how can i fix this? i need it to charge my cell and GPS...=/

SOURCE: I have a bad battery in my 2005 BMW 530i. I can't

It is located on the right side of your trunk. First lift off the trunk lining then pull out the side lining to reveal the battery among a bunch of wires. Be sure to reconnect the vent (on the front side of the battery-it is housed in a small gray tube connected to a black elbow) this will prevent gas from the battery building up in the trunk.
