306?

Not long had this car, found a key hole fixed on a bracket just under the
bonnet at the front right. Can anyone tell me what it is for.

Sounds like the alarm disable switch, but I dont have a 306 so I can't
verify it (I'm sure someone else will though!).

It's to silence the alarm siren. I've just been looking through old keys and
found the ones for my old 306's alarm, I've been looking for the address of
the guy I sold it to, you didn't buy a silver D Turbo (would be an amazing
co-incidence!!)

Amazing co-incidence it would have been , but sorry it was not me.
Is the alarm key different to the ignition key?

Worth a go! Yes it is a different key. I think it's quite a common problem
for the siren not to work anyway, mine didn't. It's becasue the siren itself
is in the passenger side wheel arch. One way you can test it is to open the
car with the key, then when you open the door, the headlights will flash, if
your lucky, you may get a siren aswell, if not, your not alone. The car is
still immobilised anyway, which I think is better than any alarm, people
just ignore them,

Cheers

My problem has been that the siren goes off at the slightest voltage drop,
so using the wipers, interior lights, etc can set it off when you are
driving along, sometimes it takes a couple of hours to settle down for the
night, the siren keeps going off for around 30 secs or more then it stops
and starts again, each time it gets quieter and quieter as if it knows I'm
going to kick it soon if it doesn't stop. If I can get a key to stop the
siren my neighbours would love me, thanks
