Alarm Going Off Continually

Post by rsccford » Thu Jan 02, 2020 6:33 pm


Our alarm keeps going off every 20 mins or so. Then stops for a few hours much to the annoyance of everyone around here. Any idea how to deactivate it? Dealers were of no help over the phone.

Mine doesn't have alarm but there's a button on the roof that disables interior movement sensor, perhaps you could try that as it maybe cars passing by or a simple fly inside the car, doesn't cost trying.
If still continues after disabling sensor then no idea how to switch off completely.
Hope the suggestion above helps

If you lock car with the key blade does that isolate the alarm?

We did have a few issues with volumetric sensors on some of them
Book it mate and get it sorted under warranty

There is a bulletin on it somewhere

Sensor can't be permanently disabled but you can press the button each time before you lock it until it's seen at the dealers

This just happened to me last week. It was a moth inside the car. You can turn off the sensors as already said, by pressing the button on the roof.
