had guy throw fifty cent coin at my rear window cos i was apparently going over a speed bump too slow, cracked rear window n i had my son in the car.. so for sure i carry somethin now, n if i sound like an aggressor so be it but ill sure as hell whack first ask questions later, if confronted like that again. anyhooo back to the keypad, happy with the system, would just be much more practical if it were slightly different, the insurance is an issue.
