A few weeks ago I heard my car alarm go off in the early morning, go into the garage and the alarm klaxon is going off but no flashing lights. I tried every thing to turn it off but would only go off and then come back on again. Then I had a thought, ear defenders on, opened the bonnet, checked the battery volts, reading 8.6. Fortunately I have an old slave battery, connected that up, alarm goes off and great relief as everything operates as normal.

Now the reason the battery was flat was mine. I went to get a parcel out of the car and left the door partly open. I meant to return to the garage and lock the doors, but got diverted, so the alarm wasn’t actually set.

I have contacted Subaru and they say if the alarm is triggered by low volts on the main battery then it can't be stopped until another battery is connected. My worry is, if you were staying away somewhere and you caught the dreaded light switch on the steering cowl and left the side lights on, the alarm could be going for hours before the AA turn up to boost the battery.

Are Subaru correct or is there some way of turning the alarm off.
