I am having "Alarm System's" problem with my Hyundai Matrix 2004 (LaVita).
Problem arise after battery changed. The control unit and the "keychain transmitter is out of sync". Means that my transmitter does not transmit any "on off" command.
Will you please detail me the step/s to rectify this problem.
My system should be aftermarket car alarm, though came fitted with the car, because it has a separate rest button underneath the steering column.
Thanking you in advance
