A transponder key is a key that incorporates RFID technology to allow vehicles to be started. Many people don’t realize that their “simple” car key, is actually a transponder key. Even though the key does not have a built in remote, it still has the programmable chip. A car equipped with the RFID technology will not start if the correctly programmed key is not inserted into the ignition. American Lock & Key can provide and program transponder keys, and remotes for your vehicle. If you need a duplicate key, or have lost your original, we have the equipment to be able to provide you with a new set of keys.
