Honda Civic: Immobilizer System - Security System - Controls - Honda Civic Owners ManualHonda Civic: Immobilizer System

The immobilizer system prevents a key that has not been pre-registered from starting the engine. Each key contains electronic transmitters that use electronic signals to verify the key.

Pay attention to the following when inserting the key into the ignition switch:
• Do not allow objects that emit strong radio waves near the ignition switch.
• Make sure the key is not covered by or touching a metal object.
• Do not bring a key from another vehicle's immobilizer system near the ignition switch.

NOTICE
Leaving the ignition key in the vehicle can result in theft or accidental movement of the vehicle.
Always take the ignition key with you whenever you leave the vehicle unattended.
Do not alter the system or add other devices to it.
Doing so may damage the system and make your vehicle inoperable.
