You will need to purchase new keys and have them programmed to the vehicles PCM

DESCRIPTION
Passive Anti-Theft System (PATS) vehicle protection system is designed to prevent drive-away thefts. The system is passive in that it does not require any activity from user. System uses radio frequency identification technology to verify if proper key is being used to attempt to start vehicle.
During each starting sequence, encoded ignition key is interrogated by vehicle anti-theft electronics. If key's identification code matches code programmed into anti-theft system, vehicle is capable of starting. If key's identification code is incorrect or missing, vehicle is prevented from starting.
PATS module communicates with Powertrain Control Module (PCM) through Module Communication Network (MCN). PCM then determines if engine will be enabled to start. If PCM prevents vehicle from starting because of the PATS system, PCM will store a Diagnostic Trouble Code (DTC) in memory.
PATS vehicle protection system consists of the following components: Hybrid Electronic Cluster (HEC), anti-theft (THEFT) indicator, transceiver module, encoded ignition key, MCN and Data Link Connector (DLC).
