How to fix the “key is not detected” for a Lexus Key Fob

Does your Lexus IS, ES, RX, NX, or LS display the “key is not detected” on your gauge cluster as seen in the video? then you may need to replace the key fob remote battery with a CR 1632 replacement battery.

The battery you’ll need is a 3V lithium and replaces the Panasonic CR1632, Sony CR1632 and Toshiba CR1632. Head over to Amazon and grab a 5 pack for only $6.97 plus shipping and handling.
