How to Disable a Factory Car Alarm
Car alarms play a vital role in keeping cars safe from theft. Modern car alarms are complex because they are sensitive to vibration and human contact. Some car alarms sound in response to the slightest movement, and others sound on their own without any prompting. Some car owners prefer to install their own car alarms rather than rely on the factory-installed ones. Before you install a new alarm, you must disable the existing one.
