Component Description

Integrated Keyhead Transmitter (IKT) 

The Integrated Keyhead Transmitter (IKT) incorporates both the PATS functions and the RKE transmitter functions in a single device.

During key programming procedures, the PATS and the RKE transmitter of an Integrated Keyhead Transmitter (IKT) are programmed into the BCM. Conventional PATS keys can also be programmed to the vehicle, if requested by the customer.

A minimum of 2 (or 4 dependent on the vehicle build) and a maximum of 8 keys can be programmed.

PATS Transceiver 

The PATS transceiver reads any key placed in the ignition lock cylinder. When the ignition lock cylinder changes to RUN or START, the BCM activates the PATS transceiver. Once the transceiver activates, it activates the key transponder in the ignition lock cylinder and receives the key data. Once the transceiver receives the key data, it sends the data to the BCM.

BCM 

When the BCM is replaced, carry out the PMI and parameter reset procedures. Additionally, at least 2 keys (or 4 keys dependent on the vehicle build) must be programmed.

PCM 

When the PCM is replaced, carry out the PMI and the parameter reset procedures.
