How to deactivate the anti-theft system on the Teana?
2 Answers
The method to deactivate the anti-theft system on the Teana is as follows: First, turn the ignition switch to OFF, then use the key to turn it to ON. Wait for 5 seconds before turning it back to OFF and wait another 5 seconds. Repeat this process three times, and then you can restart the engine. At this point, it indicates that the system has exited the anti-theft state. More information about the anti-theft system is provided below: 1. The reason why the Teana's anti-theft system activates is that the car was turned off without straightening the steering wheel when parking. At this time, the car will automatically enter the anti-theft system. The specific manifestation is that the car cannot be started, and the steering wheel is found to be locked and cannot be turned. 2. In addition to the above unlocking method, you can also directly go to a 4S shop for computer matching to unlock. Because the car's ignition key has an electronic chip, each chip has a specified ID. Only when the key chip ID matches the engine ID can the car be started. The 4S shop can match the same ID, thereby unlocking the Teana's anti-theft system.
I've been driving a Nissan Teana for several years, and dealing with the anti-theft deactivation is quite common. It mainly relies on the key: just press the unlock button on the remote key, and usually it can immediately deactivate the alarm. But when the remote runs out of battery or there's signal interference, I switch to using the mechanical key to open the door. Once inside, starting the engine right away will automatically reset the system. It's important to regularly check the remote battery level to avoid depletion; also, avoid accidentally triggering the anti-theft system, such as slamming the door too hard or pressing the key in your pocket by mistake. Once, the system got stuck, and I disconnected the negative battery terminal for about five minutes before reconnecting it, which worked effectively. However, make sure the car is turned off before doing this to prevent short circuits. Overall, developing regular maintenance habits can help reduce such issues.
