Alarm horn.....

[oblark]

Has anyone or is it possible to get the alarm horn to sound when locking and unlocking the car ???

[jdavis]

personal opinion i know but why would you want to? quite like the silent lock/unlock over a beep that sounds like a cheap tacky aftermarket jobby

Mine does and it is quite annoying, especially at 5am.

Due to where the car is parked over night I sometimes don`t see the indicators flash and have left the car unlocked all night. So I could do with a the horn sounding to let me no I`ve locked the car.

Get a small 12v buzzer and wire it to the indicators?

Oh, hang on...

Bad idea - you'll look a prat, sat at a junction going BZZT BZZT BZZT

If the car has the Guard II Alarm System which is the remote with two buttons one bigger then other it is a programable function of the alarm which to my knowledge is a dealer job using specific tool.

difference between the different alarm systems and fault checks etc.
