A Chrysler Transponder Key once programmed into a one car cannot be programmed to work any other car.
The unlock keys sold out there use at your own risk
The transponder code identification is learned by the Sentry Key Immobilizer Module during programming. The Sentry Key Immobilizer Module sends the "Secret Code" to the transponder key and is retained by the transponder key during programming. After programming of the transponder key identification to the Sentry Key Immobilizer Module and the Secret Code is exchanged, the Sentry Key Immobilizer Module will ask for the transponder identification and the Secret Code every time the key is turned to ON or START.
No Emergency "Start" procedures for Chrysler vehicles.
