There are two types of alarms available for a car. Drivers can purchase a passive or active alarm system. A passive alarm system requires user interaction to activate, while an active alarm does not. The active alarm initiates automatically, usually several minutes after the ignition is turned off or after the car door has been opened and closed. Otherwise, you can use your key fob to set the alarm, which also locks and unlocks your doors.

Step 1

Get your key fob and locate the lock button. The lock button might read "Lock" in small print or it may include a picture of a lock in its locked position.

Step 2

Press the lock button once. Press it quickly and use pressure. Do not hold it down.

Listen for a beeping sound. Some vehicles activate the alarm after one press of the button. If it does not beep, you'll hear all of the doors lock. Press the lock button again to activate the alarm.
