Chrysler 2007 Town and Country - Manual (Page 17)

NOTE: When having the Sentry Key Immobilizer
System serviced, bring all vehicle keys with you to the
dealer.
Customer Key Programming
You can program new sentry keys to the system if you
have two valid sentry keys by performing the following
procedure:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds a chime
will sound and the Theft Alarm Light will begin to flash.
Turn the ignition switch OFF and remove the second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds a single chime will sound. The Theft Alarm Light
will stop flashing, turn on for 3 seconds; then turn off.
The new Sentry Key has been programmed. The Keyless
Entry Transmitter will also be programmed during this
procedure.
Repeat this procedure to program up to a
total of 8 keys. If you do not have a programmed sentry
key, contact your dealer for details.
NOTE: If a programmed key is lost, see your dealer to
have all remaining keys erased from the systems
memory. This will prevent the lost key from starting your
vehicle. The remaining keys must then be repro-
grammed. All vehicle keys must be taken to the dealer at
the time of service to be reprogrammed.
