What to Do When Tesla Key Fob Fails to Respond
2 Answers
No need to point the key fob at Model-S, but it must be within detection range (depending on key battery strength). Details are as follows: 1. If Model-S cannot detect the key, the touchscreen will display a "key not in range" message. Place the key in Model-S's effective detection area. Radio devices with similar frequencies under the 12V power socket may interfere with the key. 2. In such cases, keep the key at least 30cm away from other electronic devices (phones, laptops, etc.). If the key remains unresponsive, battery replacement may be required. Note: Tesla Model-3 adopts a keyless design, and the provided card key can also unlock doors.
Last time my Model Y key card suddenly couldn't be detected, which was really frustrating. I guessed the battery might be dead. Tesla key cards use CR2032 coin cell batteries, which typically need replacement after about two years of use. It's simple to replace—just pry open the back cover. If the detection fails, first place the key card against the detection area below the B-pillar on the driver's side, where the signal is strongest. Stay away from interference sources like stacked phones or metal objects to avoid signal blockage. Rebooting the vehicle's infotainment system can often solve the problem: press and hold both steering wheel scroll buttons for a few seconds until the screen restarts. The phone key is also very useful—make sure the app's Bluetooth is enabled and all permissions are granted, and keep the software updated. Backup solutions include carrying a spare key card or setting up a screen PIN for unlocking. Regularly checking the key status in the app settings can prevent issues before they arise—don't wait until you're in a hurry to leave.
