Rear hatch/tailgate will not open with key fob 2011 RX 350

[TCarlson]

Batteries on my key fobs are fine. Valet button in glove box is set appropriately. Trunk release button on dash works fine. Button to open on rear hatch works fine. Rear hatch will not respond to pressing button on the key fob. I've tried resetting, removing positive battery cable, all to no avail... Any help out there?  Thanks!

Does every other key fob button work as expected?

Hey Dave, Yes every other button on the key fob works fine and as expected. This is true for both key fobs. Only the rear hatch button is non-responsive.
