Universal Transponder Bypass Kit (Key required), designed to temporarily bypass most OEM transponder type ignition immobilizer systems when remote starting. TBK III operates by using one of the vehicles spare keys to transmit the original keys uniquely CODED RF ID to the Receiver COIL in the key cylinder. The CODED signal identifies to the vehicles computer that a valid key is present thereby enabling the fuel management system. The TBK III will only operate as a bypass when the vehicle has been remote started. As soon as either the brake is depressed or an ignition key is inserted into the key cylinder (optional Keysense Circuit must be connected) the Transponder Bypass Kit (TBK III) shuts off. The keysense circuit is an optional shut off circuit and does not have to used on all vehicles.
