I had a similar problem a few years ago on my R reg Si, in the end it was diagnosed as a faulty/worn bonnet sensor and even when the bonnet was closed the alarm system thought it was open. The guy at the Ford garage said that this was quite a common problem so changed the dodgy part and it cured the problem.
Regarding your key fob, see the link below as it could be that if you changed your batteries it could nee reprogramming. Just locate which fob you have and follow the relevant procedure.
