I'm in a part of western Melbourne where the clay swells and contracts all year with varying groundwater, so every house, fence and post in the suburbs slowly but constantly moves up and down, left and right, backwards and forward. I've got a side gate attached to a fence that latches against a house, and the fence and house move differently (different depth studs/posts, probably), so I am constantly adjusting the latching mechanism (three or four times a year). In the attached pic you can see the chiselled out slot I move the metal strike plate up and down in. I've already filed out the hole in the strike plate, giving me about 5mm extra vertical play.
What I'd like is a solution that allows a lot more leeway - up to a few cm in each direction (↔ ↕) without constant need for adjustment .
As an added challenge, I still want to be able to lock it with a lockwood key (ie, same key as the house doors).
Hello @ErrolHunt
Thank you for sharing your question about your adjustable gate lock.
I understand your frustration with having to adjust your gate lock constantly. I see that you've found a solution for the vertical movement, but now you want the room to move horizontally as well. I suggest making a striker plate receiver out of Metal Mate 40 x 40 x 1.6mm 1m Galvanised Steel Square Tube.
I suggest cutting a length of at least 150mmm and marking one side as the receiver side. Mark the side you wish to cut a hole in. On the opposite side of the steel mark the area where you need to put the screws in. Cut the hole using a Ryobi 800W 125mm Angle Grinder with a compatible Cut Off Wheel.
I recommend painting the steel to protect it from the elements. Position your new receiver and test to make sure it works. I suggest putting in a Pinnacle 200mm Galvanised Coil Gate Spring to keep your door from rattling in strong wind. Please keep us updated, we look forward to seeing your gate lock fixed.

Hi the simplest solution to this problem is that the gate and latch are all part of one frame work. As to where you mount the frame mounted on the house or fence, that decision would be based on the one with the least movement. Either way the frame would float. I take it the gate is a full size for height and width.
So as the frame is structurally sound the material to use 3mm x 50mm x 50mm RHS gal
There is another method which takes a bit more work but it allows all components to float independently (house, gate and fence) that would be to add 2 section of the 50 x 50 x 600mm long to the bottom of the frame work as footings. To cover any gap between the frame work and house / fence make a trim to cover any gaps. a photo of the full gate way would be good. In the mean time I will get on my cad draw up what I am suggesting (Frame work, trim etc)
Currently I am still in Darwin and escaped Vic Dec last year so access to my CAD system is a bit different to what I have at hand here and my thanks go Darwin Mens shed for the use of their version Fusion 360
This is just a sketch to give you the prospective of how the frame work can work and yes it will be a bit more work.
I have not put any sizes to the sketch not knowing any spacings etc
The frame would be made to suite the gate / replacement gate with gate hinged on the frame, the height of the frame is whatever you see fit. The 2 x 600mm sections at the bottom are your footing / stumps /supports
At the top of the frame I would mount brackets on the house and post to provide a level of support to stop forward and backwards movement
Or just make a frame that is bolted to the house. In either method the gate and latch are set in one plan
I look at things for the long term. You have stated the ground in your area is unstable hence the gate lock and latch must be set in the same plan to prevent movement in any direction. If the gate is mounted to the fence post and the latch mounted to the house the problem will still exist as you have two moving plans
I have had a bit of time to up date my sketch to give a better prospective as stated the frame can ether be mounted to the house or set to be a stand alone.
Hello @r23on
What a fantastic suggestion to the constantly moving gate assembly! By making the gate assembly as a whole, it will stay together no matter how much it moves. Let me tag @ErrolHunt so that they are made aware of your recommendation. You could in essence apply this solution to all exterior gates.
