The US2 cloning chip is similar to/interchangeable with the CN2 but better quality and with a wider range. They can be used to clone any standard Texas Instruments 4D chip with the exception of 4D-64 (requires US64).
Please note that at the moment, these chips are only supported by a small number of cloning machines such as the KeyLogic US900. These will not work with your JMA TRS-5000, Keyline 884, or Advanced Diagnostics AD900.
IMPORTANT NOTE: We are hearing reports that CN1 and CN2 chips are not sending a strong enough signal for some Fords. In a similar way that Ford uses glass chips in their H72 (4C) and H86 (4D-60) keys, you may need to use glass TPX chips instead of black wedge style CN chips for some Fords. Please be prepared and keep some TPX chips in stock.
