Installing a gate lock on a fence will provide increased security for your home as well as keeping animals and children confined to a safe area. You will want a lock that is fitted in such a way that it is quick and easy to utilize.

Different types of gate lock designs are available for a variety of tasks although the most common type continues to be the sliding model that can also be padlocked.

Step 1 - Assemble Tools and Materials

It is best to begin this DIY project by gathering all materials together so they are at hand when you need them. This includes fully charging the drill in advance and having a drill bit that is smaller than the screw.

Step 2 - Mark Off the Screw Placement

The two pieces of the u-shaped latch should be put together in the relevant positions they will sit in when locking the gate. Place the latch in the desired location on the gate. One side should be on the gate door, and the other side placed on the post next to where the door latches.

Be sure the lock is placed evenly in place. Take a pencil or pen and mark where each screw will go on both the gate door and the gate post.

Step 3 - Drill the Screw Holes

Be sure to wear safety glasses for this step to prevent slivers of metal or wood from getting in your eyes.

Using the bit, drill holes into the places that have been marked off with the pencil. Line the drill up with the marks exactly so the holes will not be off center when screwing on the latch. It is important the drill bit is skinnier than the screw. The point is to make starting the screws easier.

Step 4 - Screw on the Latch

Fit the u-shaped latch back into place. Take the two parts of the latch apart. Line up the holes on the post side latch with the holes on the post. Screw this piece into place.

Now line up the holes of the gate piece with the holes in the gate door.

Step 5 - Try it Out

It is important to always make sure a lock is fitted properly before ending a project. Do this now by flipping the latch over the U before adding the padlock. If the padlock is easily locked into place, the job is done. If not, it will be necessary to remove the latch and try again.

This type of gate lock is a quick and easy project. Once completed, the gate can be locked at any time during the day or night. For some purposes, other types of gate locks may be desired. Sometimes, a chain and padlock may work or an electric gate lock could also be installed.
