Honda Civic Owners Manual: Keys

Use the key to start and stop the engine, to lock and unlock the doors and to open the trunk. You can also use the remote transmitter or smart entry system* to lock and unlock the doors and to open the trunk.

Smart entry remote*

The built-in key can be used to lock/unlock the doors when the smart entry remote battery becomes weak and the power door lock/ unlock operation is disabled.

To remove the built-in key, pull it out while sliding the release knob. To reinstall the builtin key, push the built-in key into the smart entry remote until it clicks.

Key Types and Functions

All the keys have an immobilizer system. The immobilizer system helps to protect against vehicle theft.

Immobilizer System

The keys contain precision electronics.

Adhere to the following advice to prevent damage to the electronics:

• Do not leave the keys in direct sunlight, or in locations with high temperature or high humidity.
• Do not drop the keys or set heavy objects on them.
• Keep the keys away from liquids.
• Do not take the keys apart except for replacing the battery.

If the circuits in the keys are damaged, the engine may not start, and the remote transmitter may not work.

If the keys do not work properly, have them inspected by a dealer.
