Nissan Altima (L33) 2013-2018 Owners Manual: 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.
