Why does the Nissan Tiida key fault light stay on?

It is necessary to check whether the battery power of the remote control is insufficient. The following is the explanation of the car fault code: 1. Car fault code: The car fault code is the fault code reflected by the car computer ECU after the car has a fault. Therefore, the car has a fault at this time and the fault light stays on at this time. To completely eliminate the fault, a professional decoder (K81, laptop computer, etc.) is required to decode, which is commonly referred to as fault elimination. 2. Types of fault codes: Fault codes include real codes, historical codes and sporadic codes. Real codes are easy to check. Historical codes, as the name implies, are fault codes left over from the past that have not been cleared, but sporadic fault codes are not fixed.
I've been driving a Tiida for several years and have encountered the issue of the key fault light staying on. Usually, it's because the key battery is running low, as the coin battery inside the key typically lasts one to two years. When the battery is low, the light will come on as a reminder. It could also be a fault with the key itself, such as a stuck button or an internal circuit short, or the vehicle's anti-theft system misjudging and not receiving the signal. Once, my light came on, and replacing the battery solved the problem. But if the light stays on after replacing the battery, you should check if the key is damp or damaged, or take it to a 4S shop to diagnose the vehicle system with a computer. It's advisable to carry a spare key regularly, check the battery periodically, and avoid sudden inability to start the car, which could affect your travel plans.
As a frequent driver, I've noticed that the Tiida key malfunction light staying on is quite common, mainly due to the key battery running out, as remote keys naturally consume power over time. Another factor is improper key placement, such as near phones or metal objects, which can interfere with the signal and cause the light to stay on. Last time, I had the light come on because I kept the key in my pocket with my phone, but it went away after I moved it to a different spot. If the light stays on continuously, it might indicate aging internal components in the key or an issue with the vehicle's receiver, requiring professional inspection. I recommend checking the key buttons for responsiveness monthly, replacing the battery promptly, and developing good habits to avoid unnecessary hassle.
