Chrysler voyager remote locking not working?

I found this on the net, it relates to the alarm systems with the battery in the key, the smart key:
PROGRAMMING THE SKIM MODULE WITH THE DRBIII
(1) Turn the ignition on. Transmission must be in
park or neutral. Alarm set lamp will flash.
(2) Use the DRBIII and select “SKIM” under the
“MISCELLANEOUS” menu.
(3) Select “PROGRAM PIN” and enter the customer
4–digit PIN number.
(4) Select “UPDATE VIN”. The SKIM module will
learn the VIN from the PCM in gasoline engine vehicles,
and from the BCM in diesel engine vehicles.
(5) Select “COUNTRY CODE” and enter the correct
country.
(6) Select “PROGRAM NEW EMS”. The SKIM
module will send the “secret key” data to the PCM.
(7) Program ignition keys to the SKIM module.
PROGRAMMING IGNITION KEYS WITH THE
DRBIII
(1) Turn ignition on. Transmission must be in park
or neutral. Alarm set lamp will flash.
(2) Use the DRBIII and select “SKIM” under the
“MISCELLANEOUS” menu.
(3) Select “LEARN NEW KEY”. Alarm Set lamp
will begin flashing.
NOTE: The PIN must be re-entered each time an
additional key is learned.
(4) Insert key into ignition switch. Once the key
has been learned, the Alarm Set lamp will turn off.
