Anyone try programing a new key?

Is this the procedure that you followed?

The Customer Learn programming method procedures are as follows:

1.Obtain the blank Sentry Key FOBIK(s) that are to be programmed as valid for the vehicle. Cut the blank integrated valet key(s) to match the door lock cylinder mechanical key codes.

2.Insert one of the two valid Sentry Key FOBIKs into the ignition switch and turn the ignition switch to the ON position.

3.After the ignition switch has been in the ON position for longer than 3 seconds, but no more than 15 seconds, cycle the ignition switch back to the OFF position. Replace the first valid Sentry Key FOBIK in the ignition switch with the second valid Sentry Key FOBIK and turn the ignition switch back to the ON position. The second valid FOBIK must be inserted into the ignition switch within 15 seconds of removing the first valid FOBIK.

4.About 10 seconds after the completion of Step #3, the security indicator in the instrument cluster will start to flash and a single audible chime will sound to indicate that the system has entered the Customer Learn programming mode.

5.Within 60 seconds of entering the Customer Learn programming mode, turn the ignition switch to the OFF position. Replace the valid Sentry Key FOBIK with a new Sentry Key FOBIK with a blank transponder and turn the ignition switch back to the ON position.

6.About 10 seconds after the completion of Step #5, a single audible chime will sound and the security indicator will stop flashing, stay ON solid for 3 seconds, then turn OFF to indicate that the new Sentry Key FOBIK blank transponder has been successfully programmed. The SKIS will immediately exit the Customer Learn programming mode. After the ignition is cycled the vehicle may be started using the newly programmed valid Sentry Key FOBIK. Each of these steps must be repeated and completed in their entirety for each additional Sentry Key FOBIK that is to be programmed. If the above steps are not completed in the given sequence, or within the allotted time, the SKIS will exit the Customer Learn programming mode and the programming will be unsuccessful. The WIN will also automatically exit the Customer Learn programming mode if it sees a Sentry Key FOBIK with a non-blank transponder when it should see a blank, if it has already programmed 8 valid Sentry Key FOBIKs, or if the ignition switch is turned to the OFF position for more than about 50 seconds.

NOTE: If an attempt is made to start the vehicle while in the Customer Learn mode (security indicator flashing), the SKIS will respond as though the vehicle were being started with an invalid FOBIK. In other words, the engine will stall after about two seconds of operation. No faults will be set.

 

If you have to go to a locksmith, shop around. Some are less expensive than others.

 

I still think that buying a fob from EBay, and having a locksmith program it, will be cheaper than buying one from a dealer (about $200).
