The anti-theft alarm system on your vehicle is connected to the horn system; it is often programmed to honk at the owner's request. Most cars come with a panic button that sets off the alarm when you press the button, but some allow a single honk when pressing the door-lock button on your key. This is called an audible-chirp feature. The availability of this feature -- and programming instructions -- depend on the alarm model.

Step 1

Check to see if your vehicle honks when you press the "lock" button on your key fob. Press the "lock" button multiple times in a row. Many devices won't beep unless you double-tap the button after locking. If the horn doesn't honk, but the lights flash, your chirp feature is probably disabled. If you do not see the lights flash, your system might not come with this feature.

Step 2

Check with your owner's manual for the the alarm system details. Not all cars allow you to set the chirp feature; it depends on the alarm model. Use your key fob to enable the program; follow the instructions listed in your owner's manual.

Step 3

Take the device to your dealership; ask about the availability of this feature on your car model. The dealership knows if this is feature was included with your car, and whether you can program it yourself. Many alarms are self-programmable, but some some require the dealership to turn on the feature.

Step 4

Use your keyless fob and ignition key to enable the audible chirp. The process varies considerably on different makes and models. You must usually consult your owner's manual, a dealership or the alarm manufacturer for the correct process.
