Nissan Altima: NISSAN vehicle immobilizer system

Nissan Altima / Nissan Altima Owners Manual / Starting and driving / Push-button ignition switch positions / NISSAN vehicle immobilizer system

The NISSAN Vehicle Immobilizer system will not allow the engine to start without the use of the registered key.

If the engine fails to start using a registered key (for example, when interference is caused by another registered key, an automated toll road device or automatic payment device on the key ring), restart the engine using the following procedure:

1. Leave the ignition switch in the ON position for approximately 5 seconds.

2. Place the ignition switch in the OFF or LOCK position, and wait approximately 10 seconds.

3. Repeat steps 1 and 2.

4. Restart the engine while holding the device (which may have caused the interference) separate from the registered key.

If the no start condition re-occurs, NISSAN recommends placing the registered key on a separate key ring to avoid interference from other devices.
