Renault Clio 1996 N Reg - Remote Locking issue, PLEASE HELP ME !!!!!?

I Have a 1996 Renault Clio with remote central locking. When I squeeze the key, the light on the key lights up. However it seems that the frequency receiver does not recieve the signal to de-activate the immoboliser or unlock the doors. Obviously I can unlock the door with the key, but i cannot de-activate the immoboliser. Your suggestions would be highly appreciated. Does anyone know if there is a way of removing the immoboliser comletely, I can live without the remote locking.........................................
