Car Alarm

Sep 23, 2007 17 Replies

Ok my car alarm has started going off once every 24 hours roughly between



4pm & 5pm, thankfully it's not in the early hours, anyway can anyone offer an insight as to why it's suddenly going off? It hasn't been in the garage since it's last service/MOT which was a few months ago.

TIA

Does this happen every day?

Somebody could be trying to wind you up by banging it every day when they finish work?

what sort of alarm is it, something might be spiking it, interference from another electrical appliance.

Don't set the alarm when you park it.

Yes m8 and it only started on Thursday

Bit of a pain in the arse to not set it as it automatically arms with the remote central locking button, would be more hassle to disarm it.

Not likely as nothing or nobody has been passing it when it's went off, also my street is a main road for the local bus service and my house shakes (well up stairs does) when buses and lorrys go past but this hasn't set the alarm off.

How much hassle is it to put the key in the lock and turn it?

The alarm still arms even doing this, I've just had a look thru the handbook and it's a pain to disarm it, anyway the bloody thing just went off again at

4.15pm, called the dealer where I bought it and it's going back tomorrow for them to look at it.

Thanks

Apologises m8, you were correct, upon reading further, i.e. turning the bloody page helps, it tells you that too disarm the alarm just use the key in the lock. The only downside is that if I forget it'll be off all night, would my insurance pay out for that I wonder?

Aie doesn't sound likely.

Okay, so, if it's between four and five, is this a certain number of hours after you've driven the car?

Some alarms go off when the battery voltage drops off, so maybe, just maybe, the battery is a bit weak.

I'd not put money on that, but, I can't think what else would cause an alarm to go off at a certain time if it isn't a local high speed train, or similar...

Just as well the alarm was set when it was nicked, then...

Well I thought about that and the first time it happened was about 2 hours after I'd driven it, then it was about 6 hours and the thing hadn't been used for about 48 hours and it went off at 4.50pm on Saturday and 4.15pm yesterday.

It is possible that the car battery is playing up. A sudden small change in voltage as happens when the cells start flaking is enough to set some alarms off. This usually happens during the night due to the colder temperatures.

you could make sure the windows are closed, the air button thingy set to recirculate and If you have it turn the interior sensor off
