It's not possible without a scantool DRBIII to replace the PCM here's why:
POWERTRAIN CONTROL MODULE
This procedure needs to be completed every time a Powertrain Control Module (PCM) is replaced.
Secret key data must be programmed into Sentry Key Immobilizer Module (SKIM) from PCM. See
SENTRY KEY IMMOBILIZER MODULE. Connect scan tool to Data Link Connector (DLC).
Turn ignition on. Using scan tool, select THEFT ALARM, SKIM then MISCELLANEOUS. Then
select PCM REPLACED. Enter secured access mode by entering 4-digit pin. Press enter to transfer
secret key to new PCM. Now enter Vehicle Identification Number (VIN) and mileage into new PCM.
Using scan tool, clear DTCs from ABS and ACM.
