Key, Transponder: Description
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
Three unique variations of a transponder key are available for this vehicle. They are:
- Sentry Key Immobilizer System Transponder Key - The Sentry Key Immobilizer System (SKIS) transponder key (1) is used in combination with an IGnition Node Module (IGNM) featuring a rotary-type ignition switch. This transponder key is used only for vehicles that are not equipped with the optional Remote Keyless Entry (RKE) system.
- Remote Keyless Entry System Transponder Key - The RKE system transponder key (2) is also known as a Frequency Operated Button with Integrated Key (FOBIK). Like the SKIS transponder key, the RKE FOBIK transponder key is used in combination with an IGnition Node Module (IGNM) featuring a rotary-type ignition switch. This transponder key is used for vehicles that are equipped with the RKE system, but not with the optional Passive Entry Keyless Go (PEKG) system.
- Passive Entry Keyless Go System Transponder Key - The PEKG system transponder key (3) is also known as a FOBIK. However, unlike the SKIS transponder key and RKE FOBIK transponder key, the PEKG transponder key is used in combination with a Keyless Ignition Node (KIN) featuring a push button-type ignition switch. This transponder key is used only for vehicles that are equipped with the PEKG system.
Regardless of the type of transponder key used for this vehicle, in addition to having to be cut to match the mechanical coding of the lock cylinders and programmed for operation of the RKE system, each ignition key has a transponder microchip included that carries a unique transponder identification code. This identification code that is permanently programmed into it by the manufacturer must be programmed into the Radio Frequency Hub Module (RFHM) to be recognized by the SKIS as a valid key.
The key transponder key cannot be adjusted or repaired. If ineffective or damaged, the entire transponder key or FOBIK and RKE transmitter unit must be replaced.
