Understanding Your Lexus RX 350 Key Fob

The key fob is more than just a way to unlock your car; it’s a sophisticated piece of technology. It uses a small battery to power its functions, including locking/unlocking doors, starting the engine, and activating the panic alarm. Over time, this battery will naturally deplete and require replacement. Recognizing the signs of a dying battery, like a weak signal or unresponsive buttons, can prevent frustrating lockouts.

A small flat-head screwdriver or a similar tool for prying open the key fob.
A soft cloth or tissue to clean the battery contacts.

Having these readily available will streamline the process.
