How to Disarm an Auto Alarm System
Your auto alarm system represents the first line of defense between your vehicle and car thieves. Unfortunately, it can also be a loud annoyance if you've accidentally triggered the alarm yourself. Your auto alarm may be triggered by improper installation, a short-circuit in the wiring, or simple user error. There are several methods that you can use to disarm your auto alarm system, but the easiest is by using the remote control unit that came with the vehicle or alarm system.
