What Are the Reasons for the Key Not Being Detected by One-Button Start?
1 Answers
Key battery dead, poor battery contact, signal interference, or internal system issues can cause the one-button start to fail to detect the key. Key battery dead: If the key indicator light does not illuminate when any button on the key is pressed, it means the key battery is dead, and the key naturally cannot be sensed. Poor battery contact: Poor contact of the internal button battery prevents the power from being delivered to the key. Signal interference: The car key cannot sense the vehicle because there is a signal interference source nearby, and the interference signal it emits blocks the sensing between the key and the vehicle. Internal system issues: Some cars' internal systems have errors after upgrades, causing the key and vehicle sensing information to mismatch, making it impossible to start the vehicle. Solutions for the key not being detected by one-button start: If the key battery is dead, replace the battery to ensure the key has power to sense and start the vehicle. For poor battery contact, open the key battery cover, adjust the battery position, or remove and reposition the battery to check if it powers on. For signal interference, provide electromagnetic shielding for the car start sensing pad or locate and turn off the interference source to prevent signal interference. Internal system issues cannot be resolved on your own; seek help from a professional mechanic or tow the vehicle to a nearby 4S shop for repair and inspection.
