Learn how to lock a Schlage door lock by following these easy steps.


If you’re looking to lock your Schlage door lock, some preparation beforehand is key. First, you’ll need the right tools like a Philips head screwdriver, a flathead screwdriver or an Allen wrench. Depending on the type of Schlage lock you have, the procedure may vary. Once you have the right tools, you can then make sure that the door, frame and strike plate are properly aligned. This will ensure the lock will fit properly, and won’t be prone to jamming or misalignment.

Gather the necessary tools

Before attempting to install a new Schlage door lock, it is important to make sure you have the necessary tools in order to avoid any potential complications or damage. You will need a Phillips head screwdriver, a hammer and chisel, an adjustable wrench, a drill (preferably cordless) with drill bit set, wood screws and 2-3/8″ holesaw for drilling. Additionally, if you are attempting to replace an existing Schlage door lock, you will also need the current key for that lock. Having these tools easily accessible before beginning the installation process can help make the process much smoother and less time consuming.

Familiarize yourself with the lock

Before attempting to lock a Schlage door lock, it is important to familiarize yourself with the specific type of lock. There are several different models of Schlage locks and some may have different features than others. Take time to familiarize yourself with the components of your specific model including understanding how the latch works, what type of cylinder is used, if it has a retraction feature or not, and even how to Cut the Key if necessary. This will ensure that you are properly prepared before attempting any adjustments or modifications to the lock.

Remove the Lock

Removing a Schlage door lock is a fairly simple process that requires nothing more than a screwdriver. The first step is to locate the two screws on the interior side of the door. You should be able to see them on either side of the knob. Remove both screws and set them aside. Once the screws are removed, you can pull the interior knob off the door, revealing the lock mechanism.

Unscrew the screws

In order to remove a Schlage door knob lock, you must first unscrew the screws that hold it in place. Depending on the type of Schlage lock, there will either be two screws or four. If two screws are present, they will either be located near the latch on the outside of the knob, or they may be hidden underneath small round covers near where your thumb would normally go when turning the handle. If there are four screws, they will be evenly spaced around an outer plate attached to your door. Once all of these screws have been removed with a screwdriver or power drill, the Combination locks should come away easily from the door frame.

Remove the interior plate

If you have a Schlage door lock and want to remove it, it’s important to understand how the lock functions so that you can go about the process properly. To begin removing your Schlage door lock, start by taking off the interior plate. The interior plate is located on the inside of your door and covers the latch mechanism. It usually has a small slot at one end that allows you to insert a flathead screwdriver and pry it off. Once removed, you will see a series of exposed screws along the face of the lock which can be unscrewed with either an Allen wrench or Phillips head screwdriver, or a cutting machine if necessary. With these screws removed your Schlage door lock should be free from its mounting plate and ready for removal from your door.

Disengage the latch

Before you can remove the lock, you need to disengage the latch that is located inside the door. The latch connects to a metal plate inside the lock’s body and must be disengaged before removal. To do this, insert a flathead screwdriver into one of the two holes at the face of the lock on its outer edge. Once you’ve inserted it, turn it counter-clockwise about 1/4 of a turn until it stops and then remove your screwdriver. Now, use a pair of pliers to hold onto either side of the metal plate located within the face of the lock and pull firmly outward in order to disengage it from its housing. With this done, your door should now be unlocked so you can proceed with removing your Schlage lock.

Install the New Lock

If you want to upgrade your SchaLge door lock, you will need to install the new lock. It’s important to install the new lock correctly to ensure it works properly. In this guide, we’ll walk you through the steps needed to install a new Schlage door lock. We’ll also provide tips and tricks to make the installation process easier.

Insert the new latch

Once you have the latch out of the door, it’s time to insert the new one. Insert its keyed side first and then its exterior side, making sure that they fit together correctly. Make sure that all of the fixing points are correctly aligned, so that when you place your screws back in to hold it in place, there won’t be any strain on them. Place the screws into their housing holes and then make sure they are tightened enough to keep the latch secure, but not too tight as this could damage the lock over time.

Insert the interior plate

Once you have the exterior plate and knob in place, it is time to install the interior plate. Begin by inserting the interior plate into the door as shown in your installation instructions. Once it is in place, insert two of your provided screws into the top two holes of the door jamb and loosely secure them.

Next, take your screwdriver and tighten all four screws of the interior plate. If your installation instructions are compatible with your door type, use those steps to determine which order screws should be tightened. Firmly tighten all four screws until they are flush against the interior plate. Make sure that you have not overtightened any one side or section of the interior plate, as this could damage it or leave a gap between plates when fully installed.

Finally, take one of your provided mounting screws and attach it to secure the bottom part of the interior jamb to your door frame. Make sure that this screw is long enough to go through both plates but short enough so as not to protrude out too far beyond either piece – you don’t want a screw sticking out past either side where someone might snag their clothing or a hand on when using your lock! Now you have successfully added a new Schlage door lock!

Secure the screws

Once the deadbolt is in place, it’s important to secure the screws that hold it in place. This will make sure that no one can remove the lock without a significant amount of force. To do this, you’ll need to have several screwdrivers of different sizes. You should have a Phillips-head and flathead for the two screws on either side of the strike plate. Once those screws are in securely, you can insert a small hex key into the main bolt from outside your door and twist it clockwise until it won’t turn anymore. This will ensure that the lock is securely in place and no one can remove it from outside your doorway.

Test the Lock

Before locking the Schlage door lock, it is important to do a test first to make sure it is working correctly. To test it, turn the thumb turn all the way until it stops. You should hear a sound coming from the lock indicating the button has been pressed. If the sound is heard, then the lock is working properly and it is ready to be locked.

Test the lock with the key

Before you can be sure that your Schlage door lock is properly installed and working, you’ll need to test the lock with the key. To do this, first insert the key into the keyhole and turn it clockwise until you hear a clicking sound. This indicates that the cylinder has been correctly placed in the lock. Next, turn the key counterclockwise and make sure that it moves smoothly back to its original position. If everything is working correctly, then your Schlage door lock is likely functioning properly.

In addition to testing with a key, it’s also important to test your Schlage door lock without one. To do this, start by turning the knob in a counterclockwise direction until you hear another clicking sound. This noise indicates that your knob has been properly connected to the chassis and is ready for use without a key. Finally, make sure that once you have turned the knob counterclockwise, you can open the door by pushing or pulling on it gently – if not, check for obstructions inside of the frame or other damage before attempting further action.

Test the lock by turning the knob

Once you have installed your Schlage door lock, it is important to make sure the lock is functioning properly. To test the lock by turning the knob, start by closing and locking the door. Then turn the knob from the locked position counterclockwise to the unlocked position several times. During this process, you should hear two distinct clicks; one as you reach from one direction and another as you go in reverse. If these clicks can be heard correctly, then your Schlage Door Lock is functioning correctly and ready for use.

If no clicking sound can be heard or if you hear only one click sound when attempting to unlock the door, gently jiggle or pull on the knob while still turning counterclockwise until you hear both clicks or repeat until they key turns without resistance and unlocks fully. If this does not resolve your issue with hearing both clicks, contact a professional technician to assess any further issues that may arise with unlocking your Schlage Door Lock.

Ensure the lock is properly secured

Before using and trusting a Schlage Door Lock, you must ensure that it is properly secured. There are a few things to check before test the lock to make sure it is working properly.
First, ensure that the faceplate screws have been tightened securely by using a screwdriver. To do this, turn them clockwise until there is no more room for them to move.
Second, open the door latch and push the latch bolt into the strike plate; make sure it is touching or almost touching the outer edges of the strike plate with both sides being evenly aligned.
Finally, close the door and inspect it for any signs of interference or obstruction in its operation-none should be present. If you experience any problems, make sure you loosen or tighten all screws as necessary before testing again. If issues persist, contact a professional locksmith for help.
