Car wont start or central locking wont work?

it was temprimental for a while, i had to wait until the emobaliser light went out before it would start, now it will not start atoll and the central locking will not work. it is not the battery because the lights and radio still work|||It could still be the battery, cars need some voltage but primarily rely on amperage to start. What type of vehicle is this?|||One of your car computers has a problem. GOOD LUCK|||the immobilizer system is fault, get that changed and u will not have a problem
