Immobilizer System Components

IMMOBILIZER SYSTEM COMPONENTS

The immobilizer system includes these components:

^ Immobilizer system keys (two master keys and one valet key at new vehicle delivery)

^ Immobilizer system indicator

^ Immobilizer control unit receiver

^ ECM/PCM

Immobilizer System Keys





The vehicle comes with two master keys (black grip) and one valet key (gray grip).

Each master and valet key has a transponder in its grip that outputs an ID code when you insert the key into the ignition switch and turn it to ON (II). The immobilizer system uses this ID code to determine whether to start the engine.

Some master keys have a battery-operated remote transmitter built into the grip that lets you lock and unlock the vehicle. The keys without remote transmitters contain no batteries or other serviceable parts.

When you need to cut a new or duplicate key, use the appropriate tool from the Honda Tool and Equipment Program. Call or on the Interactive Network (iN), click on Service > Quick Links > Tool and Equipment Program.

Immobilizer System Indicator





The immobilizer system indicator is on the instrument panel. If you insert a programmed ignition key (master or valet) into the ignition switch and turn the switch to ON (II), the indicator comes on for 2 seconds and then goes off. When you turn the ignition switch to LOCK (0), the indicator blinks for 5 seconds and then goes off.

If you insert a nonprogrammed ignition key into the ignition switch and turn the switch to ON (II), the indicator comes on for 2 seconds and then starts to blink. The indicator keeps blinking until you turn the switch to LOCK (0). If you try to start the engine with a nonprogrammed ignition key, the engine cranks, but it will not start.

Immobilizer Control Unit-Receiver





The immobilizer receiver is inside the bezel around the ignition switch. It uses electromagnetic induction to power the transponder in the key. There is no direct electrical connection. Once the transponder is activated, it sends its ID code to the immobilizer control unit-receiver, which checks the ID code against the codes in its memory. If the code matches, the immobilizer control unit-receiver sends a unique serial code to the ECM/PCM. But if the transponder ID code does not match, no serial code is sent.
