I HAVE A SIGMA ALARM WITH CENTRAL LOCKING AND FOB LOCKING, IF I PRESS THE CENTRAL LOCKING BUTTON FROM INSIDE THE CAR, IT LOCKS AND UNLOCKS THE CAR, BUT IF I PRESS THE BUTTON ON THE FOB THE CAR WILL NOT OPEN, AND I HAVE BEEN TO A GARAGE AND HAD THE FOB TESTED AND IT IS FINE, ALSO WHEN I OPEN THE DOOR WITH THE KEY ONLY THAT DOOR OPENS, THE OTHER DOOR OR THE BOOT DOES NOT OPEN, THIS ALARM IS ON A MK2 CLIO

Sounds like for whatever reason the Fob isnt synched to your alarm anymore (have you had a flat battery ....) Contact Tech-Tronics in MCR, they may be able to sort it for you.
