Did you know that when your SmartKey Fob battery dies, you still can enter your vehicle and start the engine? After I got a “key not found” message, I started the experiments shown in this video so that I can know whether I still can drive the car even if the battery is dead. I will explain how the auto keyless system works and I will also show you how to replace the battery if you choose to.
The example used in this video is a Nissan Leaf 2015. However many cars use the same system. It could be called SmartKeys, Keyless Entry, Keyless Go, Keyless Access, or Passive Entry system.
