KD-X2 is a multifunctional automatic key programmer that is very popular among locksmiths with its compact body and powerful functions. More than just a cloning device, the KD-X2 is also capable of transcribing transponders, reading and writing to/from transponders, performing frequency testing, and generating transponders, all in a few simple steps. The KD-X2 also uses a built-in snooping device that notifies you when you have collected the necessary ID46 and ID48 snooping data. This key cloning tool is as small as a phone, so you can simply put it in your pocket and take it. To avoid the power supply issue, the KD-X2 is built with a 1600mAh lithium battery, allowing you to decode hundreds of times when fully charged.
