Locked out of a 1990 525i

[Wolfgangk]

I have a 1990 525i that does not unlock. I've tried using the key and handle on the passenger side and it only lifts part way . Not enough to unlock the door. Help

Hi. Is the car fitted with a ski hatch in the boot? Can you unlock the boot and charge or replace the battery? 

[Wolfgangk]

Thank you for your response. I can get into the trunk but unfortunately I don’t have a ski pass through and the battery is under the hood. I’ve had a professional try to unlock the doors but no joy. Thanks again.

Is there a 12v socket in the trunk? Can you remove the rear lights and input 12v that way?

OK can you not raise the car and through the engine bay pull the bonnet release cable, once you have access to the engine bay you should be able to change the battery and power the door locks 

The only car I have had real problems with had no battery fitted at all

Good Luck

Thank you for the suggestion. I’ll definitely try it.
