What is the reason why the Teana's car lock horn does not sound?

[LaDante]

The reason is that the lock horn mode was accidentally canceled. Simultaneously press and hold the lock (LOCK) and unlock (UNLOCK) buttons on the smart key for more than 2.5 seconds. The hazard indicator will flash once, and the horn will sound once, enabling the horn mode. Below are specific details about the Teana: 1.
