I hear car alarms going off all the time. Do they even help? Have they saved your car before?
This depends on what kind of alarm you have. If it doesn't have some sort of motion detector, then a person can break a window out and just crawl threw the window and steal something. Most of your basic alarm system only activate if someone opens the door, which will trigger the alarm. Any noise will usually run a thief off if they think it will drawl attention .
Mostly NO ! Professionals can Bypass most Add On CAR ALARMS! The best defense it to Buy An Upscale Car like a Volvo, Mercedes, BMW and the LIKE! There is a Computer Chip in the KEY. that will allow ONLY THAT KEY to start the KEY! In addition my Car. has a TRANSMISSIONELECTRONIC LOCK-OUT ! Thanks, RR
i dont know really i guess they do ?
