CN1 Ceramic Cloning – Use for cloning 4C chips in transponders such as TOY43AT4, TOY40, TOY48, Ford H72
The US1 cloning chip is similar to/interchangeable with the CN1 but better quality and with a wider range.

They can be used to clone any Texas Instruments 4C chip.

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.

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.
