Identification of Texas Instrument crypto transponders (RW4)
There are multiple versions of TI crypto transponders, which in many cases are reverse compatible. This means a more modern, higher security transponder may be programmed into an older vehicle.
This causes great confusion because a new key blank purchased from a dealer to suit an older vehicle may have the latest, higher security transponder installed.The RW4 will identify the TI crypto transponder generation, and inform the user if it can be cloned.
After reading the transponder, the RW4 will present the identification with a prefix to indicate which generation of transponder is in the key.
prefix | Description |
---|---|
6F | Texas Crypto 2 (80 bit chip in old 40 bit mode). Can be cloned. |
6A | Texas Crypto 3 (80 bit chip in new mode). Can't be cloned. |
6E | Texas Crypto (with mutual authentication or new mode). Can't be cloned. |
An identification example: '6A-63'.'6A' indicates a new 80 bit Texas Crypto transponder configured in 80 bit mode. The last two characters in the identification refer to the application configuration as featured in the table (63 for Ford/Mazda).
