This type of reprogramming typically done using a transponder cloning machine, that can copy a particular circuit board or transponder. Some key blank manufacturers as well as some experts in reprogramming provide this equipment. The device that is cloned must be capable of reading the data that is sent on each of the transponders that are being cloned.
