Diagnostics of a fault

With an OBD scanner, it is possible to check if the fob is still communicating with the receiver module. This is a straightforward process that can give an initial indication of where the issue is. If the OBD scanner reports that there is no communication between the receiver and transmitter modules, it may be required for the fob's transmitter module to be replaced. This is a costly option and should be left to a locksmith.
