Battery flat on 1997 840 - doors and boot wont open with key - is there an emergency way to open either door or bootlid so that i can charge battery ?
What exactly have you tried with the key?

Sorry for delay - had to go out.

Have tried unlocking drivers door with key but doesnt unlock - tried to unlock boot also with key but again no luck.

Dont have an owners manual but was wondering if there was an emergency procedure to open door in the event of battery failure ?

Due to the time I'm quite happy if you reply tomorrow morning.

Many thanks

Hi Steve
Are you still out there ?

I will provide an honest answer. I trust this will be appreciated on a Saturday. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.

they key should still work despite the battery being flat

either you need to turn it as far as possible, past a resistance point, or, you need to pull up on the door handle and hold it up while turning the key as far as possible, per this image: or per this link:

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
