Abstract: Provided is a system and method for duplicating a master key for a vehicle. The system includes determining that a first device is communicating with a t/r device, the t/r device including an antenna for communicating with the master key. A cloning application associated with said t/r device may be operating on the first device. The t/r device may retrieve security information from said master key. The cloning application may communicate the security information for said master key to said central network system. The central network system may generate duplicate security information. The central network system may communicate the duplicate security information to the cloning application. The cloning application may transmit the duplicate security information to the t/r device to program a duplicate master key with the duplicate security information.
