How to troubleshoot a remote locking issue in a BWM?

I am facing issues with remote locking in my BWM car. Whenever I try to lock the car remotely, the locks do not engage and the car remains unlocked. How can I troubleshoot and fix this issue?

First, check the batteries in your key fob and replace them if necessary. Sometimes, a weak battery can prevent the remote locking function from working properly. If the batteries are not the issue, you may need to reprogram your key fob. Consult your car manual or a professional mechanic for instructions on how to do this.

Another possible cause for remote locking failure could be a faulty actuator in one of the car's doors. A damaged actuator can prevent the remote signal from reaching the other doors. Inspect each door's actuator and replace any damaged ones.
