What is the reason for the Nissan Sylphy's keyless entry not responding?

You can check the induction module on the door handle. It is likely that this is the issue. Below is a related introduction to the Sylphy: Exterior: The new Sylphy largely follows the design of the overseas version, featuring Nissan's family-style V-motion front grille, with the headlight cluster connected to the grille, making the LED daytime running lights appear sharper. Additionally, the new front bumper enhances the car's sporty look. Interior: Inside, the new model is more stylish compared to the previous version, with an embedded LCD display on the dashboard and a simplified button layout. In terms of features, the car is equipped with Apple CarPlay, lane departure warning system, blind spot warning system for lane changes, rear cross-traffic alert, multifunction steering wheel, one-touch start, dual-zone automatic climate control, and front seat heating.
Last time my Sylphy was parked in the underground garage of a shopping mall, the keyless entry system completely stopped responding, which was really frustrating. Looking back, it was probably due to a dead key fob battery - these small button batteries usually last one or two years before needing replacement, and changing it typically solves the issue. If that doesn't work, there might be signal interference from nearby sources like large LED advertising screens or electric vehicle charging stations, as their strong radiation can easily block wireless signals. Another possibility is dust covering the sensor area on the door handle - a gentle wipe might restore functionality. Sometimes it's caused by unstable voltage from the car's main battery, which indirectly affects smaller systems. I recommend keeping spare batteries handy; if problems persist after replacement, drive to a 4S shop to check the control module or re-pair the system. Regularly cleaning the door area monthly can help prevent such issues.
