525 trunk problem - BMW Forum

I have a 2001 BMW 525i and am having problems with my trunk. The fob, the button in the car and the button on the trunk all will not work. Only thing that works is the key. I did not leave the lock in the valet position. So I am thinking a fuse might be out. Does anyone have any suggestions?

Start with the fuse. But check ALL the fuses. A fuse that looks okay might actually be bad. It's worth the few extra minutes to check all of them to make sure.

Do you Have experience with a problem like this?

In a sense yes, its a very common problem for the Central Locking System to malfunction in some way. Numerous people on several BMW forums have experienced issues with locks not working properly. Usually the cause can be attibuted to the fuse blowing. Other problems include the door actuator not working anymore, and the entire CLS's ZKE Module failing. If the ZKE module failed you would not be able to unlock any of the doors from the remote and they would have to be unlocked manually. If the fob doesnt unlock any of the doors, the issue may lie with the module behind the glove box. It is a small black box with a green connector coming out of it, and it will have an FCC ID number on it.

I had exactly same problem, I had 3 broken wires in the rubber hose from boot to bootlid, now all working fine!
