I have been hovering here for a while but I thought this was worthy of a response, I am 5 months into X5 ownership.

This is a very old thread but I am sure its still helping lots of people. It helped me complete a seemingly impossible and expensive task - how do you fix the lock if you can't open the door to get the door card off?!

I followed the instructions and it worked perfectly for me. Two things I will say - make sure you read step 1 properly, I originally put the rod down the wrong gap and had no luck but in the right spot the door was open in seconds!

Second thing is I had a can of copper grease spray and I used this to lube the lock, I took it out the door to do this but realised that you can spray the lock in situ and work the handle a few times until it moves freely. It doesn't save much time but its worth noting, might be worth a precautionary spray on all other locks!

The hardest part for me was getting that stupid plastic clip in the middle of the door car back in to the bracket when putting the door card back on!
