Alarm Starts for no reason

Hi.
A friend of mine who does'nt speak english asked me to open a thread about the issue. Sorry if the thread is unclear.
He says:
While the BMW 745's doors are locked, suddenly the car alarm starts beeping till we unlock and lock the doors again. Any idea what could the possible reasons be ?

Best way to find out is to read the error message with a reader, but it most probably is the hood open/towing sensor in the engine compartment. Check to see if he has a sensor on the driver side once you open the hood, it will be a contact black sensor, disconnect it and way to see if the alarm goes on again. This was happening to me if I left the car outside and the hood got hot, didn't do it if parked inside the garage
