The car alarm sounds whenever the doors are locked. A professional garage has identified via the OBD2 that the alarm control unit battery is low. Could someone please advise me:
Where is the alarm control unit located on the car so that I remove it?
Can a new battery be put into the alarm control unit or does it require a replacement unit?
If I buy a used alarm control unit, will the ECU (or whatever) recognise and communicate with the used part, or can I get it programmed/coded, or do I need to buy a new unit?
