Found this a while ago in another forum. I don't have the Sentry Key system so I've never tried it. If it dosent work, I'd take it to a locksmith to be programed not the stealership, their usually cheaper. Call around.
"This programming method requires access to at least two valid Sentry
*1 Get blank Sentry Key(s) that are to be programmed as valid keys
for the vehicle. Cut the blank key(s)
*2 Insert one of the two valid Sentry Keys 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
three seconds, but no more than fifteen seconds, cycle the ignition
switch back to the Off position. Replace the first valid Sentry Key in
the ignition switch lock cylinder with the second valid Sentry Key and
turn the ignition switch back to the On position. The second valid
Sentry Key must be inserted in the lock cylinder within fifteen seconds
of removing the first valid key.
*4 About ten seconds after the completion of Step 3, the SKIS
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.
*5Within sixty seconds of entering the Customer Learn programming
mode, turn the ignition switch to the Off position, replace the valid
Sentry Key with a blank Sentry Key transponder, and turn the ignition
switch back to the On position.
*6 About ten seconds after the completion of Step 5, a single audible
chime will sound and the SKIS indicator will stop flashing, stay on solid
for three seconds, then turn off to indicate that the blank Sentry Key
has been successfully programmed. The SKIS will immediately exit the
Customer Learn programming mode and the vehicle may now be started
using the newly programmed valid Sentry Key. Each of these steps must
be repeated and completed in their entirety for each additional Sentry
Key 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 SKIS will also automatically exit the Customer Learn
programming mode if it sees a non-blank Sentry Key transponder when
it should see a blank, if it has already programmed eight
(8) valid Sentry Keys, or if the ignition switch is turned to the
Off position for more than about fifty seconds."
