Everything is replaceable—even that heavy duty lock on your door. But worry not, for this is something you can fix on your own! No professional help needed, unless things are too complicated to deal with. 

But before anything else, do you have the basic knowledge to start that door lock replacement? If not, then lucky you because we’re going to walk you through everything. Let’s begin!

Why is Changing Your Lock Important? 

Changing locks or rekeying locks is one of the most important parts of ensuring a safe, functional home. Safety and security is a human need, so we should do what we can to provide it to ourselves and our loved ones. With the regular checking or changing of locks, you also gain extra peace of mind knowing that your home is safe and sound. Here are a few reminders before planning to replace that lock. 

Note that it is important to make an inventory of all the locks around your home. By doing this, you will be able to pinpoint which locks need changing. In buying a new lock for your door, it is advised to look for knobs or locks like your old one. Or those who have a matching code. This way, it would be easier to replace or “fit” your new knob without making extra adjustments. Purchasing a different one isn’t a bad idea too, if you’re up for a change!

What Things Will You Need? 

Here are the things you will need in doing your own project. First, is the new lock. As you purchase that new lock, you’re going to notice that it already includes the pieces that rekeying requires. This refers to the mounting hardware and the interior turner. Next is a measuring tape. This is important especially if you bought a lock which is different from the original one. While most new models are adjustable, you still want to make sure it fits just right. 

Of course, there’s no question that a screwdriver is a must. Before pulling it out of your toolbox, determine whether you’ll need a flathead or a Phillips screwdriver. Yes, there’s a difference between the two. 

In a few words, a flathead has a single blade, while a Phillips screwdriver has two blades in the shape of a cross. Knowing which one to use is important because using a flathead tool on a screw designed for a Phillips won’t work, and vice versa. Depending on the screws, you may need both. 

A Step-by-Step Guide in Changing Locks

Now that we have elaborated the things you’ll need, let’s change those locks! 

Step 1: Remove Your Door’s Old Lock and Hardware

The first step is to remove your door’s old lock and hardware. This part is one of the easiest. You simply have to locate the screws on the interior side of the lock (the side with the turner) and remove them, along with the turn plate. There should now be a hole where you can see through. 

To make things easier, you can open your door so that you can see the side of the lock, or the narrow part on the side of the door. You should locate and remove those screws as well. You can now remove the rest of the hardware from the door.

Step 2: Install Your New Lock

The next step is to install your new lock, or new deadbolt. Pick up your newly bought hardware and install it where the old one used to be. Most deadbolts have labels which indicate “up” on one side to help you pinpoint where to position it. You can now use the provided mounting hardware in your assembly kit to secure things in place.

Step 3: Insert Your New Lock

The third step is to insert your new lock. The deadbolt has slots where you can fit both the key part and the turning part. Pay attention as you assemble the pieces in their right place, and secure those pieces in place using the screw found inside your assembly kit. 

Step 4: Test It

The fourth and final step is to test it. Remember to always test your new lock after changing it instead of just assuming that it works. This is to ensure that all the pieces are in their right place, and that the screws have been screwed properly.

In doing so, make sure that it locks and unlocks using the key, and that it locks and unlocks using the turner.

And…we’re done! One last reminder that doing things on your own isn’t always easy, but it doesn’t mean that you can’t do it. However, if things become too hard, don’t hesitate to call for professional help. You may also want to consider switching to the programming Schlage lock, where you need to press three to four numbers (your code) to unlock your door. There are traditional locks, and there are locks improved through technology. Good luck with your locks!
