How to Troubleshoot an Auto Alarm System
Auto alarm systems are about as common as car keys these days. They are a good idea too, if you have to work or live in areas where there is a high auto theft rate. It seems that there are about as many car alarm makers as there are cars to put them in, and while there are differences in design and sound, the aim is singular---protect the car. Since the variety of alarms is so vast, and the vehicles they are bought for are so numerous, only general tips that fit most alarms and vehicles can be offered.

Check your interior dome light first, if your alarm does not arm itself as it should. Turn the switch to "Off," or set it to come on when opening the door only, usually the middle setting on the switch. Make sure you turn off all other after market added equipment the battery is powering.

Cars without alarms are cars with open doors in some areas. Test your alarm to see if it arms itself. Exit the car, watch and listen for the horn beep or other signal the alarm is activated. Read the owner's manual section about setting and adjusting the alarm sensors on your particular car and alarm system if the alarm does not set itself.

Be careful about adjusting the alarm sensors. Do not set them on a level that makes them too sensitive to exterior motion and movement, since this will cause phantom alarms or false alarms. Adjust the alarm current sensor so that it does not go off in response to a sudden power/voltage drop from the battery that is still servicing other electrical components.

Valets will certainly appreciate Valet Mode. Check the system's Valet Mode next to make sure it is working. Set the alarm's Valet Mode to avoid triggering unwanted alarms. Insert the key into the ignition and turn the ignition on without starting the car. Hold down the button for 10 seconds.

Watch for the LED indicator to come on and stay solid. Keep holding the set button down as you turn off the switch. Release the button when you have turned off the switch.

Valet Mode is great, but do not forget to turn it off when your car is returned. Make sure the system will now deactivate the Valet Mode. Turn off the Valet Mode, so the alarm can be re-set. Stick the key into the ignition and turn the switch on, but do not start the car.

Depress the set button and turn the ignition off in one motion, and remove the key. Do not hold the button down longer than one or two seconds when turning off Valet Mode.

24-hour mode is ideal when you must leave your car unattended for extended periods. Check your alarm system's 24-hour mode. Depress both the "Start" and "Lock" buttons at the same time and hold them down. Hold and wait until you hear the confirming note or tone. A clock will appear on the LCD screen signifying the 24-hour mode is armed.
