Most car alarms will automatically reset themselves after a certain amount of time usually around 30 minutes. However if the alarm has been triggered by an attempted break-in or other suspicious activity it may stay on longer to deter would-be thieves. If your car alarm won’t reset it’s best to consult your car’s owner’s manual or contact the alarm’s manufacturer for instructions on how to reset it.
