hi.. there is a common problem with laguna's.. not the imobiliser.. but the plug on the fuel pump that causes it making you think it's the imobiliser (happened on two different laguna's i have had), just remove the panel in the boot floor and disconnect the pump plug, clean all the connections (plug and socket) and refit.. it's that easy (happens on petrol and diesel models, i got the info from a local renault mechanic) i did it on both mine and it worked great, never had any more problem... hope this helps..
