What do you mean by 'fitted a spider' ? The 300's came with a spider, so have you replaced a duff one, just blithely added one or what? I'd suggest you need to re-check the wiring whichever is the case ..

We're not psychic ...

Does it seem to lock everything OK? ie do all doors lock, if it does and you leave a window open then wave something in front of the sensor does it sound off? Does it still have a bonnet switch?

I'd also check the battery is good and fully charged, has a good earth and that all earths on the body/engine/gearbox/chassis are good.
 
OK, did it work OK before fitting your spider?
 
Mine will do this sometimes, lock it and within 40 seconds the light will start to flash. Also the siren will sound for no reason at all. Mine even goes off with the car unlocked. I've been told that its the alarm module thats the cause
 
fixed i hope i think it was down to a earthing problem the earths next to the battery on the inner arch. only cleaned the contacts up yesterday. so far so good hopefully no more no problems. thanks fore all the help guys
