In this guide, I will teach you how to lock your patio door to prevent unauthorized access to the patio section of your house. Using a patio lock is one of the best methods to use to make your patio area a no-go-zone. It is quite an easy procedure.

As a quick summary, to lock your patio door, first, pick a position for the lock on the door. Proceed to mark the position of the lock on the door with a pencil. Now put on your safety glasses and drill two 3mm pilot holes in the door frame. Go ahead and set the lock on the frame with the screws, and then mark the position of the receiver on the door.

How to lock your patio door

After gathering all the tools and materials required for this task, follow the procedure below to secure your patio room. Also, make sure you have a power source for your power drill. (1)

Step 1: Pick a position for the lock on the door

Mark the position of the lock on the door frame using a pencil. To do this, take your door lock and place it on the door frame at a considerable height. So, you do not bend too low or stretch too high to open your door. Go on and set the lock on the door frame all around. Use a well-sharpened pencil with a dark mark so you do not lose track of the mark.

While marking the door lock position, keep the lock 2.5 mm away from the sliding section of the door. 

Step 2: Drill two 3mm pilot holes on the door frame

The first thing to do in this step is to put on safety glasses. Drilling the holes releases fragments randomly and at high speeds. These fragments can damage your eyes in an instant. After protecting your eyes, open the door to avoid damaging it in the process of drilling. (2)

Now fit your 3 mm metal drill bit into the power drill. Now drill two pilot holes on the door frame at the door lock positions you just marked. The pilot holes should be in harmony with the screw sections on the door lock. It is very crucial for fitting purposes.

Step 3: Position the lock on the door frame

To secure the lock on the door frame, grab and place it on its section. Take one screw and insert it into the screw section of the door lock. Use the screwdriver to secure the door lock on the frame.

Step 4: Mark the position of the receiver on your patio door

Slide or lock the door to mark the receiver position. Ensure your door fully closes otherwise your door will not lock.

Now, to mark the receiver position on the door, push the door into the lock position. You need to leave a mark on the center point of your door. If the marking is unclear, press the lock knob or button with pressure.

After identifying the mark, switch the 3 mm metal drill bit in the power drill with the 12.7 mm metal drill bit. Go ahead and drill a 12.7 mm hole in the receiver section. Make sure you do it gently and carefully otherwise you will drill right through the door.

Step 5: Fill in the plastic escutcheon

Now, once the 12.7 mm hole is ready, fill in the plastic escutcheon. You may use a hammer to secure it properly into the hole. The plastic escutcheon counters wear and tear. It also provides a professional feel by making the door look decorated.

Step 6: Test the lock

On completing these steps, proceed and test if your patio door lock is working properly. Simply slide your door and lock it. Check if it is locking well.

If you follow the procedure your door will lock seamlessly.
