Before you start digging around for a new battery, it’s essential to confirm that the battery is indeed the issue. Here are some telltale signs that your Lexus key fob battery might be on its last legs:

Decreased Range: Are you finding yourself having to stand closer to your Lexus to lock or unlock the doors? This reduced signal strength could point to a dying battery.

Locate the release button on the back of your key fob. This is typically a small button or switch.
