Before you remove the locking system you already have on your patio door, you should figure out the right model. Many of the manufacturers of sliding patio doors put a model number or the manufacturer name on the edge of the door. You should locate the model and put it down somewhere. If you need to replace more than just the latch on the locking system, you might need the model name.


Taking Off the Handles

Now, you can start removing the locking system for the patio door. You will start by taking off the handles on your door. Generally, this is done with a Philips screwdriver. There are usually two screws that keep the handle on. Now put the lower screw into its hole where it was attached to your handle so the latch doesn’t fall in the door. Another tip is to keep the handles supported when taking them off so they don’t fall to the floor.

Now there should be two screws at the door’s end that keep the latch secured. Take these screws off and easily pull the latch out along with the cartridge it was held with.
