Why my pager"keypad" goes off it is pretty damn loud,even if they bump the car the alrm my not sound but the keychain will still beep and let me know the cars been bumped.and if the door opens the keychain goes crazy and shows lil picture of the door open..i love my alarm and it has served me so well..and yes the zoombak is the best way to go..Not to be a fucker but it will be so funny if my car ever does get stolen,and 10people come rolling up to the bitched house or where ever itiis"cause i will not call the cops"cause i know they will just get out of jail the same day..but a broken arm and fingers will take awhile to steal another car
