alarm system key for a peugeot 405

[joko]

does anyone know where i can get a new key for the alarm system for my peugeot 405 auto estate?

I assume you have to buy them from peugeot with all your documents... or are they universal?

you can only get to the keyhole if you have opened the bonnet, so i suppose they could be universal.

the mot guy turned it off as the alarm wouldn't turn off because of key fob batteries - now i can't put it back on and he can't remember anything about it - so perhaps garages have a universal key...?

any ideas?

thanks

tried rellacing the batteries in the old key fob?
