If you don't have a patio door lock, you should. They are inexpensive and easy to install and add protection for your home. If you place the lock up high, you will add extra protection to young children getting out of the door.

Step 1 - Getting Ready

First, decide if you want to install the lock. The top or the bottom of the door are the most common places. If you have small children, consider installing the lock on the top portion of the door. Start by placing the locking side on the base of the door and mark the holes with the marker. Do the same on the other side of the door.

Step 2 - Installation

Using the correct drill bit, drill the holes that you have marked. Then, on the door where the slide bolt will go, drill a hole where the bolt will be placed. Using your magnet, clean up all the metal shavings around the holes.

Then, screw in the base and bolt sides, drawing the bolt back into lock position. Once they are attached, check the bolt to be sure it fits in place smoothly and stays locked when you pull. You may have to adjust the holes for the bolt if it doesn't close smoothly. Just drill another hole going into the hole you already drilled and make your adjustments.
