The phrase describes a common issue affecting modern vehicles equipped with remote keyless entry systems. Specifically, it denotes the condition where the battery within a Toyota vehicle’s key fob, used for functions like unlocking doors and starting the engine, is nearing depletion. This situation can manifest in various ways, such as decreased range or complete failure of the remote to function.
Addressing this issue promptly is vital for maintaining vehicle accessibility and convenience. A functional key fob is integral to the seamless operation of a modern Toyota vehicle, impacting security and the ability to utilize features like remote start (if equipped). Ignoring a low battery warning can lead to being locked out of the vehicle or unable to start it, causing considerable inconvenience and potentially requiring costly professional assistance. The evolution of keyless entry systems has made this a more prevalent concern than traditional key-operated ignitions.
