Why is the Nissan Teana's one-button start not working?

[DelBrynlee]

The common reasons for the Nissan Teana's one-button start not working are as follows: 1. The Nissan Teana's keyless entry system has a specific authentication zone. A valid key must be detected within this effective authentication zone for normal entry and startup. Beyond this zone, normal entry and startup are impossible. The authentication zone is divided into external and internal zones. 2. The driver makes an error in the door-opening action without realizing it. When the driver pulls the door handle while simultaneously touching the small groove on the outer side of the handle, the door cannot be opened or locked. 3. The Nissan Teana has been parked for an extended period. After the car has been parked for a long time, the keyless entry may fail to work when used. This happens because the smart entry system enters a power-saving mode and stops functioning after the car has been parked for a while. To use the keyless entry again, the driver must press any button on the key to deactivate the power-saving mode, after which it will function normally.
