What are the reasons for the Nissan Sylphy's keyless entry not responding?
2 Answers
Reasons and solutions for the Nissan Sylphy's keyless entry not responding are as follows: Signal interference: Bring the smart key close to the ignition switch. If the vehicle can start, it is likely due to strong external interference sources. Try moving the car to an open area. If it still doesn't work, it might be caused by interference from aftermarket devices like dash cams or navigation systems you installed. Contact with metal materials: When the smart key comes into contact with metal materials or is covered by them, it may also affect signal reception. Low key battery: If the key battery is low, try replacing the battery to see if it improves the situation.
My Sylphy also had a keyless entry failure issue last week. After struggling for a while, I found out it was due to a dead key fob battery. Later, when consulting my mechanic friend, I learned that apart from key issues, the vehicle's induction module could also malfunction. He took apart the door handle and found that poor contact in the induction coil inside prevented signal reception. Another possibility is unstable voltage from the car battery, causing the computer system to automatically shut down power-consuming functions. My neighbor had it worse - his system failed when parking at a mall, only to discover that a nearby car had installed a strong signal interference device. Usually, it's important not to place the key and phone together as magnetic field interference can also cause recognition failure. If all else fails, you can try holding down the unlock button on the key fob to re-sync the signal.
