Spring Maintenance Guide for Your Door Locks

Door locks get used every single day of a trip, which makes them one of the more important things to check over before the season gets going. The Milenco Inside Outside High Security Door Lock (model 4718) is built to fit external walls between 25mm and 50mm thick, with anti-bump countermeasures and the ability to lock from both inside and outside the vehicle.

What to check

Test that the key turns smoothly from both sides, since this lock's whole point is dual-direction operation. Check the surrounding fixings haven't worked loose over a season of use, and make sure the visible external locking mechanism still operates cleanly — it's part of the deterrent, so it should look and feel solid.

Fitment reminder

This lock only needs a 30mm gap between the door frame and any internal furniture, which makes it compatible with a wide range of vehicles including the popular Ducato. If you're checking an existing fit rather than installing new, it's worth confirming that gap hasn't been reduced by any interior changes made over winter.

Keeping the lock body free of grit and giving the mechanism an occasional check will help it keep operating smoothly, whether you're parked at a campsite or on the move.
