Hi all, I have just purchased a Mazda Cx7 with two remote key fobs. I can pair them both with the car (opening, closeing door, on off ignition etc) but they will not retain the setting for more than a half an hour. Can you help me what am I missing or what am I doing wrong. Any help would be very appreciated as I am wairing out the door hinges continually trying to set the remotes.

 

Sounds like the keyless entry module is faulty.
