Immobilizer System Components
IMMOBILIZER SYSTEM COMPONENTSThe immobilizer system includes these components:
^ Immobilizer system keys (two master keys and one valet key at new vehicle delivery)
^ Immobilizer system indicator
^ Immobilizer 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. There are no batteries or other serviceable parts inside the keys.
The master and valet keys for 2003-04 Odyssey, 2003-04 Pilot, and 2003-05 S2000 models are sidewinder-type keys. When you need to cut a 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 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 powered up, the key sends its ID code to the receiver, which then sends the code to the ECM/PCM. The immobilizer receiver contains no logic circuitry; it does not need to be rewritten when replaced.
