Car alarm excitement...

[Ray Luxury-Yacht]

Bought a Honda S2000 from a mate recently.

It has an alarm / immobiliser fitted, no idea what make it is...but it also has a proximity sensor idea, so that if you walk past or stand next to the car, the alarm gives a quiet, fairly unobtrusive long 'beeeep' to warn you that the car is secured with this alarm. Might put people off the idea of buggering about with the car, I guess.

Anyway, I also have a wireless doorbell on the house. Has a button on the front door which wirelessly connects with the chime unit inside. I started to have problems with the doorbell not working, and occasionally chiming by itself, without anyone pressing the button outside.

After buggering about with it, changing batteries and stuff, I finally realised there was a connection to it's malfunction.

Basically, when I lock the Honda, and the alarm and proximity sensor arms, it interferes with my doorbell and stops it working! Weird! Then to add to the fun, one evening the doorbell went off, and I opened the front door to find no-one there, but the car alarm going off and even stranger, one of the car's electric windows have wound down too!!!

The only way I can get the doorbell to work now is if I park the car, lock it and disconnect the battery.

Anyone else had any similar strangeness of this kind?

I would say you were being haunted.

Didn't some bmw's behave in a similar manner?

Can you change the frequency the door bell works on. Sounds like it is on the same frequency as the alarm system.

Quality car alarm, it can be foiled by a doorbell

Not really 'strange', but my MX5 had a Selca alarm fitted that was quite good, but worked via microphones mounted on the sides of the dashboard. One night in extremely heavy wind, it went off about five times in a row. Perplexed at the problem, I eventually disabled it via the keyfob (which also locked and unlocked the doors on arming/disarming the alarm) and locked the doors manually with a key before going to bed. Mind you, that was the only time it caused me problems and the wind was a 'once in a year' kind of wind! I miss that alarm system for it's cool array of bleep-bloop noises.

There were a few thefts from car a couple of years back where you'd park up, walk away and then blip to lock your car. People were using doorbell radios to block the central locking, and then helping themselves to the stuff in the car.
