My alarm is giving me grief all of a sudden. I have the Clifford Matrix RS 3.5 DEI will not test my alarm without a reciept. I believe the brain unit is malfunctioning. All functions that are powered by the remote are not responding. The remote tells me it is transmitting(pager style). The signal is not being recieved. My locks are still locking after starting the car, and my shock sensor LED is lighting when I bump it. There is a wire that can be used to remote start the car without the remote. You touch ground twice quickly, and bam, startup. That function is also not working. Could be the brain. Could be the antenna. Could be the remote. Can't test any of them myself, and have no chance of Warranty testing without reciept and proof of "professional" installation. I have been using this alarm for over 1 1/2 years, installed it myself in two cars, and this is the first problem I've ever had.
