There is a chance they didn't reattach all properly (even tho' the camera line is fiber optic).
Did you confirm that you are first unlocking the vehicle?

And yes, I checked that valet mode is off, it's just the boot lid button that doesn't work.
I recently got my rear camera replaced because it was glitching, and coincidentally it's attached to the boot lid button so perhaps there's a chance that they didn't hook everything up properly?
