Try putting a new Battery in the key fob if you have a new Battery in the fob already the security ecu could be malfunctioning and that will be a serious problem because if you have to replace the ecu you will need to have the keys and new ecu coded and that can only be done by Lexus .Weather they will attempt to work on your car is another issue as they may not be able to get the parts that are needed.

Hello Alfred and welcome to the LOC.

As Ambermarine suggests try a new Battery 1st, I take it you have the key with the single button on the side.

If you have a spare key try that to see if it works correctly.
