Pick the model year first: Opel Signum keys change between generations, and each year page lists only the keys that fit it. Then match the part number or FCC ID printed on your original remote with the specifications on each listing. Every remote listed for the Opel Signum 2003–2008 transmits on 433 MHz.
A new smart key or remote has to be programmed to the car with a key programmer, and when every key is lost the programming is still done through the diagnostic port. We ship the key worldwide from the UAE by DHL and FedEx; any automotive locksmith or the dealer can cut and program it.
