Greetings, everyone.
I own a 2004 530i vehicle and it seems that I have inadvertently caused damage to it without any knowledge of how it occurred.
Yesterday, my key fob was functioning well without any indications of a low battery.
I installed a dash cam directly into the fuse board located in the trunk and also installed a reversing camera.
During the procedure, my key ceased to communicate with the automobile.
The car's ignition is functioning well, however there is a malfunction with the remote locking/unlocking system, trunk opening mechanism, and window controls. There is nothing.
The wire is routed through the centre of the rear seat, then extends towards the driver's side and is concealed behind the black felt material towards the front of the vehicle.
I have attempted to synchronise it once again, but unfortunately, it did not provide any positive results. Furthermore, I have detached the battery, but this action did not prove to be effective.
I have eliminated the cameras and wires completely - there is nothing left. I have examined the receiver in the rear window thoroughly for any indications of moisture or corrosion - there is no evidence of either.
All fuses are in proper working condition.
While not catastrophic, when I open the door with the key, the alarm is triggered, requiring me to swiftly start the vehicle and disable the alarm.
I am quite perplexed since the signal does not resume even after removing the cameras and cables.
While I was fitting, I had the key in the ignition (in the off position). Is it conceivable that I inadvertently triggered a power surge, resulting in the battery in the key being damaged?
Has anybody else encountered this?
Thank you.
