This is a specialised seed-key calculation tool developed by DiagCode, designed to generate the correct security access key from a given seed value used in FCA vehicle control units. By calculating the precise response to the ECU's security challenge, it enables authorised access to protected functions and procedures within supported control modules. This tool performs seed-to-key calculations only and does not provide direct diagnostic or programming functionality.
This is a software activation. All current:
Simplediag any software activation customers
SKGT customers
can enable this function because they already have a security dongle.
New customers who wish to purchase it and do not have a security dongle must purchase one along with the activation.
