Customer Question

Hello, I have an E40 320d My locking system doesn't work, so the car wont lock and now all the windows go down when I shut the door. They only go up again after the engine has been running for about 5minutes. I have been manually locking the car for quite some time now as I refused to pay over a £100 for a new fob!! Can you help?

I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.

I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.

Thank you,
