HOW TO MAKE MY CAR BEEP
It might be the alarm system; or your car is going haywire.
"Beep-beep"
a constant beep is the overheat alarm a beep that goes in and out is low to no oil alarm
the alarm
If the alarm on a 2000 Honda Accord is randomly making noise there may be a problem with the wire harness. When the brain or siren has a short it will randomly make noise and sound off the alarm system in the car.
Normally you hit the lock button twice to make the horn beep, but I think your car does a double beep but it not the horn if it dont beep anymore you could have it fixed but would it be worth it?
It is very easy to disable a Toyota Camry's car alarm. There is a toggle switch underneath the dashboard, on the left side of the steering wheel. Flip the switch while starting the car until you hear a beep. This disables the car alarm.
On your keyless entry remote hold down the panic button and trunk button at the same time till the remote light flashes. Then the "beep beep" of the alarm will sound when locking and unlocking your car.
It depends on the model. You'll have to provide more information as to which model/series you bought. If you have a pager that was given to you with the alarm system, you should push the "unlock" button once. The pager and car beep will beep twice, and your pager should update the "unlocked" status of the alarm.
Thunder, rain, or defective sensor
Each beep means something different - One is a confirmation tone for decoding, one could be for bluetooth headset (if you have one) and the other can be a single beep which can randomly go off.
