Amateur Door Lock Installation Mistakes

Is replacing a loose door knob on your “honey-do-list” for this upcoming weekend? It may sound simple, but we hear from beginners all the time about these basic mistakes. Before you attempt to replace a doorknob, take a look at this list of common mistakes so you can avoid making them.

While the information is fresh in your mind, jump on over to our step-by-step guide to learn how to properly remove an old door knob.

What are the most common mistakes when amateurs install door locks?

Installing a new door lock or doorknob always seems like a simple task to homeowners, but it only takes one minor mistake to prevent a lock from working properly, thus putting your security at risk. These are the most common door lock installation mistakes.

Orienting the New Lock Incorrectly

One of the most common mistakes homeowners make is placing the new doorknob or deadbolt improperly and only realizing this after the screws have been installed. Make sure you’re looking at the new lock in the correct orientation.

Misaligning the New Lock

If you’re replacing a deadbolt door lock, you must be sure the deadbolt is aligned correctly. Otherwise, you could end up having to purchase an entire new door. Make sure all three holes are aligned correctly.

Drilling Holes in the Wrong Way

If you have to drill the saw hole in the door, start from the inside and look for the drill to begin to show on the other side of the door. When you begin to see it, stop drilling and switch sides to continue drilling. This will minimize splintering and potential damage to the door.

Measuring from the Bevel

Your door will not close correctly if it’s not measured properly. Make sure to measure the position of the lock from the side of the door that is not beveled.

Locking Yourself Out

If you’ve made it far enough where the new lock installed, the next thing you’ll probably do is test the lock. Make sure you have the keys in your hand! Few things are as embarrassing as making the amateur mistake of locking yourself out of your home.

Not Following Instructions

If this is the first time you’re installing a door lock or doorknob, it’s a good idea to review the instructions. They’re included for a reason. Give them a good once-over before throwing caution to the wind.
