So I was getting into my friend's car and my pager alarm was hooked to my jeans. I closed the door and now there is black ink all over the led screen. I can't see if the car is locked/unlocked. It still functions correctly but I just want to replace it with a brand new one. Could I just buy any pager and make it work with my exsisting alarm? (My alarm is a Clifford Matrix 1.x) TIA.
