#1 How to remove the sliding door from the track?
Simply keep the door in tracks and tilt it up as if you’re pushing it into the upper tracks. This should give you a little space at the lower part. While holding the door with both hands from the middle pull it gently but firmly.
Depending on the make and type of your door you might need to use a screwdriver to loosen the screws at the bottom rollers adjusters a bit.
You might also want to enlist the help of a friend because the door could be too heavy. And make sure the kids are away.
Pro Tip: take a lot of pictures before you start working just to know how it originally looked like.
#2 How to put in a sliding door
Push the upper part of the door into the upper track frame. Once you’re sure it’s secured in its tracks, proceed with angling the lower part into place.
A flat screwdriver will help give a little extra push from the bottom to lift the door up. Preferably, use the screwdriver to push up from the wheels/rollers adjusters side. So, you lift the door at the same time.
Most important: ensure the rollers are tucked on the tracks. Also, tighten the screws as much as you can.
Pro Tip: Be gentle. Don’t try to “muscle” it out.
#3 How to replace the sliding door lock
First, just use a screwdriver to unscrew the latch. Usually, there is one screw at the top and another to the bottom. There might be a third one holding the lock itself.

Often, you don’t need to replace the knobs and handles just the lock.
Pro Tip: Take particular care of the dimensions.
