vauxhall astra (T Reg) Car key will no longer operate central locking. ?
 
                The key will centrally lock the car from the drivers door, eg all doors lock when I do it manually. But the key will not work remotely. Im thinking there must be a battery in the key which has run out, is that right? If so whats the cheapest way to get it sorted.
