Hi,i was wondering if anyone knew if my 1998 galaxy 2.3 ghia ever had a remote key. i just bought this and it only came with one key which unlocks and locks on central locking fine,but i can see a little flashing light on the top of the trim directly above the lock on the inside which flashes which possibly means it did.does anyone know where i can get a replacement and how much,? many thanks
