ABUS Purpose made internal deadlocks to fit Fiat Ducato front doors on motorhome or van. Fits perfectly under the door trim of this model, no new drilling necessary. Turn the white knob & the lock slides behind the B-piller. Unlock with the key. Photos 3&4 show equivalent locks currently available to buy & price for a drivers side only is £150+. I am offering both driver & passenger locks together.
