Hi New to this site.

I have a fiat Multipla 1.9 diesel 110 ELX JTD.

I am having problems with the ignition key and alarm as the key no longer switches off the alarm and I have put new batteries in the handsets . The red light comes on the key but doesn't operate the alarm ?

Do you not have to reset the key to the alarm in someway? Read the owners handbook as I'm near sure there is something about syncing the key to the alarm
