Hi All, had my citroen since December and finally getting round to investigating this issue.
When kids or dog are left in car while i pop into a shop for example they need to keep the keys as the alarm continuously goes off with them inside, very annoying.
The button on side panel that disables the internal alarm does not work at all, the panel is functioning as the child lock button works fine.
I have tried the instructions of pressing button within 10 seconds of removing key but no success. Anyone else had this?
I looked at the manual and there are no separate fuses for this, should a fix for this be under the manufacturers warranty?

Hold the button down for about 6+ seconds. I found this when leaving sunroof open.

Hi, yes agree with that. On mine it's around 2 seconds(!) but definitely have to hold it until LED comes on.

Lock the door with the ignition key. This should lock the car without activating the alarm.

Hi guys. Can some one please let me know if citroen c5 aircross got security red light(by windscreen, usually blinks when car is locked). For some reason I don't see it on my citroen. Just wondering if it actually there or not.

On the C3 Aircross the flashing light is in the manual door lock/unlock button below the touch screen. The flashing indicated the engine immobilizer is active.

On my C5 Aircross, there is a red flashing LED on the switch panel under the steering wheel on the right hand side.

On our C5A its like Beenee said, under the main central display screen.
One of the manual piano button switches has the manual unlocking facility, this is what flashes on ours, when doors are locked.
