Modern vehicles rely heavily on sophisticated keyless entry systems. The convenience of push-button start and remote locking is a welcome change from traditional keys.

Replacing the battery yourself not only saves money but also allows you to address the issue immediately, avoiding the inconvenience of a malfunctioning key fob.

The smart key, a crucial part of the modern Toyota RAV4 driving experience, relies on a small battery to transmit signals to your vehicle. Over time, this battery depletes, leading to decreased range and eventual failure. Knowing the signs of a dying battery is the first step towards a seamless replacement process. Some common indicators include needing to be very close to the vehicle for the key fob to function, intermittent operation, and the key fob not responding at all.
