SOURCE: Hello accent 2004 with anti theft system battery flat anti theft

Have you verified this system is running the battery down? The system you describe is called the Remote Keyless Entry System (Electronic Time/Alarm & Control System - ETACS Module). It cannot be 'disconnected' without disabling other systems (intermittent wipers, Chime bell, Door Warning, Dimming Off Room Lamp, Seat Belt indicator, remote power door lock/unlock system, etc.)

pretty quick. but be sure it the alternator. You can test it by starting the car then unplugging the battery. If it cuts off when you unplug it it's the alternator if it keeps running it's not the problem

SOURCE: where is the battery located in a 1990 bmw 7

For an 1990 735i, under the back seat, passenger side. To get to it, you must grip under the cushion of the backseat (near the floor, not seatbelts) and pull upwards. There are three latches that you must disengage on the left middle and right. it requires a nice amount of strength to do it, but it can be done, usually standing up in the back facing the seat gives nice leverage.

I hope that work for your model and all 7 Series. Good luck (remember rated this help).

Testimonial: "Thanks alot, I finally got to that battery."

Hi geox43,

I think that you'll have to visit your BMW dealer and ask them to scan and recode the anti theft unit..
