Introducing Canberra Locksmith. We can do standard keys and Transponder keys for almost all makes and models. We use top quality Silca Transponder keys or Genuine Transponder keys from your vehicles Dealer. Transponder keys have been used in almost all Passenger cars in Australia since about 1997. When the car key is turned in the ignition, the ECU on the car sends an electronic message to the key and it will allow the car to start only provided it receives the correct message back.
