Car alarm on hot days

[maldotcom2]

My car (VS SII) has an aftermarket alarm system installed, im not sure what it is exactly. When the car heats up in the sun, the alarm goes off until i go unlock/relock it, then it's fine.

At the moment i'm looking at having to get a completely new system installed because of this problem. Does anyone know things i could check?

I had a similar problem with a cheap crap alarm. Fairly sure its related to the quality of it

Just get your new one done and all should be right.

I had this problem with my $600 alarm system. Do you have any switches attached to your bonnet?

In my case it turned out to be the little button switch that they stick where the bonnet closes. There was just enough contact with the bonnet, but when I parked it in the hot sun, everything expanded and the alarm went off within 10 minutes without fail.

I am having the same annoying problem and yes I do have a switch for the bonnet. How did you rectify the problem? I don't particulary want to replace the entire system.

I went to Bunnings and bought a pack of those small adhesive plastic buttons for like $2 and stuck one on the underside of my bonnet, at the point where it makes contact with the switch when shut.

Do you know its the bonnet switch for sure?

That's brilliant :thumbsup: I am off to get some.

No I don't know for sure but if the above tip doesn't work, it's a good bet that it isn't the switch.

Cheers.

That button I stuck on has been there for about 5 years now and still hasn't fallen off, and it gets pretty hot in my shed during summer where the car is stored.

Thanks for the suggestion, i do have that switch at the front and my bonnet sits a little high at the front. I'll try that idea. Thanks.

Tip worked a treat :thumbsup: I stuck on the little rubber protector where the switch meets the bonnet, parked the car in the sun and not a peep from the alarm. Thanks MasterOfReality! :bow:
