Here’s guide to clone a chip key on Chrysler, Dodge, Jeep that requires sniffing aka snooping using the CN900 Mini or ND900 mini cloning machine. This particular vehicle is a 2014 Jeep Wrangler and used a Y159-SH with a CN3 chip inside.
Different between Smart CN900 MINI and CN900:
- ND900 is the China version CN900 car key copy machine. They perform same functions, different in outlook. (PS: they use different 4D, 46 cloner box when copy 4D/46 chip). So Mini version CN900 is abroad version and mini nd900 is domestic version instead.
- CN900 mini inherited most of CN900’s feature but mini one make car key copy easier without connecting with 4D, 46, G Decoder Cloner Box.
- Mini CN900 comes with built-in battery, do not need to attach to the power adapter.
- CN900 Mini support WiFi, Bluetooth and internet connection. The big size one do not support.
- CN900/ND900 Mini will replace big CN900 in the near feature.
