Keys and Locks Immobilizer System The Immobilizer System protects your vehicle from theft. A properlycoded master or valet key must be used in the ignition switch for the engine to start. If an improperlycoded key (or other device) is used, the engine's starting circuit is disabled. When you turn the ignition switch to ON (II), the Immobilizer System indicator should come on for a few seconds, then go out. If the indicator starts to blink, it means the system does not recognize the coding of the key. Turn the ignition switch to LOCK (0), remove the key, reinsert it, and turn the switch to ON (II) again. If the system repeatedly does not recognize the coding of your key, contact your Honda dealer. This indicator will also blink several times when you turn the ignition switch from ON (II) to ACCESSORY (I) or LOCK (0). The system may not recognize your key's coding if the key is in contact with a key from another immobilizer system. If you have a key from another vehicle's immobilizer system, keep it separate. Do not attempt to alter this system or add other devices to it. Electrical problems could result that may make your vehicle undriveable. If you have lost your key and you cannot start the engine, contact your Honda dealer. As required by the FCC: This device complies with Part 15 of the FCC rules.
