The Intelligent Access (IA) key incorporates both the PATS and the RKE RKE transmitter functions in a single device. The Intelligent Access (IA) key must be located inside the vehicle for engine starting and on the outside for Intelligent Access (IA) features. During key programming procedures, the PATS and RKE transmitter of an Intelligent Access (IA) key are both programmed into the RFA module. The RFA module accepts programming of up to 4 Intelligent Access (IA) keys. Refer to KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT or Refer to KEY PROGRAMMING USING TWO PROGRAMMED KEYS for the key programming procedures.

The Intelligent Access (IA) key receives the low frequency signals from the passive start antennas. When the Intelligent Access (IA) key is activated by one of the low frequency signals, it sends out a high frequency signal that is received by the TPM module. The Intelligent Access (IA) key also contains a key blade that is used to enter the vehicle as a backup.
