Matrix rs2.5 stopped working

when you dropped the suv at the repair shop did you leave the remote too.Try reprograming the remote yourself by opening a door leaving it open then put your key in the cylinder and press the valet button once and then once more and hold it till you hear the siren chirp once the siren chirps keep holding the valet button and press the lock button on the remote you should hear a chirp after that this indicates the alarm accepted the remote.try to enter the program mode in less than 5seconds or else your going to have to repeat it by putting the key in the cylinder and starting the procedure over again.If the programing of your remote does not work then yor remote must be damaged from inside, your going to have to replace it. I had the same problem with these remotes you have to be carefull not to abuse them in anyway cause they won't respond and they will beep letting you know no signal.
