single beep from alarm when locking

[silvermilnec]

I get a single beep from the alarm when remote locking. Sometimes i don't get the single beep but after a few minutes the alarm goes off!

I have replaced the Head unit and i know you need to put tape on the left side to complete the alarm. The new H/U is a tight fit so maybe the tape as come off but i don't think so.

Any other ideas.

Cheers Chris

Is it the horn beep or the usual 'chirp' from the alarm you get when locking/unlocking remotely?

If it's a horn beep then likely something not closed properly e.g. centre console or lids. It's a feature of the alarm to inform you of the potential security problem.

Dave - You shouldn't get a chirp when you lock/unlock the car.

Chris - The system logs recent events, so if you could get a diagnostic check done it would be able to tell you exactly what set off the alarm. As Dave says, it could be a switch on the lids, the interior monitoring sensor, or the radio contact.

Mine started to do a single beep but was okay when using the deadlocks. Turned out to be defective door locks. I don't think that fault is wholly uncommon?

I just checked and I get one in time with the four way flash when unlocking/disarming and two when
locking. Fairly sure it's always been that way. Does that mean something?

Two beeps when locking means there is a system fault. The LED on the dash will also double-flash when the alarm is set.

You are not pressing the button twice are you? That disables the internal sensors (and gives the 2 beeps as a confirmation - as Richard says, it's a warning that something is not enabled).

It's the same beep as i got when i first changed the H/U before Richard the great informed me i needed to tape the side of the unit. Maybe the tape as come off the side when pushed in. Can the H/U connection be disconected?

Thanks for the help.

Just disconnect it and insulate the end of the cable. It's a complete waste of time anyway, as anyone breaking into the car would have set the alarm off long before they reached the radio!
