Strange question.

Until getting around to repair the drivers side door closed sensor (ie warning light constantly on. Vehicle will remote unlock but not lock) I need to be able to lock the rear swing up door. The book says manual locking for the tailgate is via key in socket, of which there is none! Is there an internal lock like the side door? (My rear door has had its panel replaced.) If not how?

The turn and hold on the drivers door doesn't trigger central locking either.

Tnx
