Hahaha! AlbertRoss! Well, What about the use of alarms to deter monkeys from breaking into a car just to steal whatever (might) be in it? Maybe this is a better use? About 5 weeks ago I got up one Sunday morning and wandered over to the nice sunny front window. It's afirst floor flat and the Xantia was parked on the street below - I casually noticed the driver's door was simply ajar... being a shiter, the first thing I thought wasn't "some little cunt has broken into my precious shite heap" no, it was " can that happen"? i.e can something go wrong with your central locking or door lock to cause it to pop open... no was the answer I gave myself.. I went down to find it had been broken into sure enough but the hadn't smashed the glass, simply broken into via the door lock, not damaging the barrel but instead bending the handle surround enough to reveal a little gap and then got a hacksaw blade with a notch on it and used that to pull the rod up (I reckon) as I noticed that all 4 doors had conveniently opened for the intruders. They had almost legitimately opened it! I'm getting to the point. The point is that the factory alarm wasn't on because there had been an ongoing shite problem with it - it was causing an electrical fault to keep the indicators stuck on all the time even after you locked it or when started and driving. The only solution was to put off the alarm and pull out the alarm fuse. It had been like that for weeks. The central locking worked with the key but the alarm gets armed by the remote (with the fuse out the alarm goes off even if you open on the remote) so the break in didn't set off the alarm. Luckily I don't leave anything of value in there and generally scrotes don't steal old diesel shitters. Little fux did take my new (albeit 5.99) driving aviators out of H&M and oddly, stole a crappy halfords phone charger and very oddly, stole a little packet from the glove box containing the standard Xantia replacement clutch plastic clip (why?) I suppose they HAD to steal something. The key thing is I had no idea the car had been broken into until next morning - it could have happened while I was sitting near the window or sommin. Had the siren went off though I'd have been down there and casually opened the boot to get the can of black undersealant to spray in their face. So now the alarm and deadlocks are used since they seem to work OK for now. I think car alarms still have a purpose for that reason anyway. Hopefully they'll not touch it now as it's known as the shite heap with nothing in it..
