Tailgate not clicking shut

New here! I've got an L405 and the auto upper tailgate is not clicking shut. It closes ok but wont click shut hence I can't lock the car. Replaced both batteries in car and had them programmed to car. Issue was there before batteries were replaced by the way. The issue seems to be intermittent too. Have greased the lock mechanism too. Also reset the tailgate to no avail.

Cheap enough if it's correct for your vehicle. Sure it will be easy enough to change and a couple of hundred quid cheaper than one hours labour at a Land Rover dealer.
