How to Install a Sliding Door Patio Lock Latch
The first step is to go to your local hardware store and pick out the style brand and color of the Patio door lock you like. Remember to measure the width of your sliding door (some locks only support thin doors and if it is an internal or external locking mechanism.
The lock I chose was a Lockwood Onyx Patio Sliding Door Lock Black. Which was around $70. The white was more expensive for some reason at around $90. This lock supports doors up to 50mm wide. These are Australian prices at Bunning’s.
Some of the cheaper patio door locks only had 1 tab for latching and could be less secure or only supported by 40mm or less sized door frames. So as I had a wider wooden door the Lockwood Onyx was the obvious choice.

How To Replace Your Glass Sliding Door Lock
Depending on the type of latch you have this should be a very straightforward job. My front door lock latch only had 3 long screws holding it on. So once these were removed the latch just came apart. Others may require a cover to be removed first and then the mounting bolts can be taken out.
Another reason for picking the Lockwood was that the latch I was replacing was on old Lockwood sliding door lock so it had the same mounting hole locations.
Installing Sliding Door Patio Lock
Patio sliding doors will require some prep work will before installing the new lock. Take the contents out of the package and cut out the template for the mounting screws for the lock handle and latch. My holes lined up perfectly but had to drill them out to 10mm as per the instructions. Old holes were about 8mm.
Next dry mount the 2 sides of the Lockwood handle and see if it all lines up. Take a ruler and measure the thickness of the door and cut the lock tab bar to suit. It was about 15mm. then cut to suit. Remember if you use the spacer plate to add 5mm to your cut. A pair of pliers or side cutters is fine to cut the bar. Remember measure twice cut once.
Screw-in the Lockwood handle using the supplied screws. I found these were hard to screw in because the handle threads were not recessed tapped. Not sure if this a manufacturing fault or if its made like this, so I screwed them in first to make a thread in a vice. It’s good to have someone help you line it all up while you do this.
I also used the supplied spacer on the inside handle as I found my knuckles hitting the door frame at times during testing. Guess I have large hands then. The spacer made it perfect. This is why you do a dry run before cutting the lock tab past 15mm
Mount the handle and screw in tight using the 2x short screws.
(use the correct length screws there are 3 choices for different width doors)
Drill the holes for the latch and mount with the supplied wood screws. I ended up using long wood screws that I had to make the latch bracket more secure. I guess I’m a little more paranoid about home security. Make sure it all lines up and make adjustments as necessary.
The only adjustment I needed was to latch and the door was about 4mm too wide to latch closed. To fix this loosen the 2 screws on the ends of the metal wall bracket latch and then loosen the middle screw. This pulls out the inner metal tabs to make the lock line up. Instructions say not to adjust past 4mm.
And that’s all there is. Now go out and replace all of Patio Sliding door locks yourself saving some well-earned money in the process. This process works the same with replacing your screen door lock.
