Power lift gate not opening or closing, two beeps. (1 Viewer)

[UCrazyKid]

My rear glass lift gate will not open with the press of the interior button, or close once manually opened with the button on the lift gate OR from the remote. The vehicle responds with two beeps.
Any idea what is going on? I just got the vehicle back from the mechanic for a new radiator, water pump, v-belt and pulleys. I don’t see how there could be a connection, other than if they let the battery run down or something while having the truck.
Thanks in advance.

Is the power door button in the auto position?

I don't know that I have that option, 2011 LX570. I only know of the activation button on the dash to the left of the steering wheel, by the wheel heater and easy access button. Is there somewhere else I should look? Thanks!

Never mind, I found it. Thanks!

Never mind, I found it. Duh. the mechanic must have hit the button with their knee. All is working now.
Thanks!
