In this blog post, we’ll show you how to remove a commercial door lock cylinder without a key. This is a great way to change out a lock cylinder without having to replace the entire lock.

Gather the Tools

Before you can start removing a commercial door lock cylinder without a key, you need to gather the necessary tools. This includes a pair of safety glasses, a screwdriver, a drill, a pair of pliers, and some lubricant. Once you have these tools ready, you can begin the process of removing the lock cylinder.

Obtain a screwdriver

In order to remove a commercial door lock cylinder without a key, it is important that the correct tools are gathered for the task. The first tool to obtain is a screwdriver. Depending on the type of lock and commercial door, this could be either a Phillips or flat head screwdriver. Additionally, if the screws inside of the lock are security screws, then it may be necessary to have a specialty screwdriver such as a star-screw standard bit or an Allen-head bit. Once the appropriate screwdriver has been acquired, it can then be used to remove all screws that are part of the faceplate for the lock.

Obtain a pair of needle nose pliers

When you need to remove a commercial door lock cylinder without the key, you will need a few basic tools. First, you will need to obtain a pair of needle nose pliers. The pliers should have pointed ends and be able to fit into the keyhole in order to grab onto the lock cylinder. Once you have your pliers handy, it’s a good idea to also gather together some graphite powder or WD-40 lubricant in case the cylinder is stuck. This is an important part of the process as it will ensure that you do not cause any damage while trying to remove the cylinder. Finally, make sure to also have a flashlight available so that you can see what you are doing deep inside of the lock when it’s time to manipulate it. Having all of these items nearby before starting your project will help make the removal process go quickly and smoothly.

Obtain a flat head screwdriver

To begin successfully removing a commercial door lock cylinder without a key, you will need to gather the necessary tools: a flat head screwdriver, an Allen wrench or Torx bit, and a small pair of needle nose pliers.

The flat head screwdriver will be used to leverage the retaining plate that holds the lock cylinder in place over the latch. Once you have access to the latch and pins of your lock cylinder, you will need an Allen wrench or Torx bit (depending on if your lock has tamper-resistant screws) to loosen the set screws securing the various pins of the lock in place. The needle nose pliers can then be used to remove them from their slots and free up the tumblers for rekeying or totally replacing.

Remove the Door Knob

Removing a commercial door lock cylinder without a key can be a tricky process, as it generally requires you to access the door knob’s interior components. In most cases, the door knob can be removed by loosening a set screw at the base of the door knob then gently pulling it away from the door. This will reveal the inner workings of the lock cylinder and the key hole. Keep reading to learn more steps on how to unlock the cylinder without a key.

Unscrew the door knob screws

In order to successfully remove your commercial door lock cylinder without a key, you will first need to unscrew the two door knob screws located on either side of the door knob. These screws should be easily visible and accessible. Carefully unscrewing these should release the door knob from the door itself. Once these have been removed, you will be able to access the lock cylinder within.

Remove the door knob

Removing a commercial door lock cylinder without a key requires a few tools and some basic knowledge of how locks work. Commercial door locks have cylinders that can be removed when the screws installed in the back of the door knob are taken out. To get started, you will need a flat head screwdriver, a straightened paper clip, needle-nose pliers, and an electric drill with different sized bits.

Begin by unscrewing the two small screws on either side of the handles or knobs on both sides of the door. Use a flat head screwdriver to do this. Be mindful not to strip any of the screws during this process. Once both screws are removed, pull off one side of the handle and grab hold of the cylinder body that runs through it.

Next, insert your needle nose pliers into one side of the cylinder body and use them to pull it out from its cutout in your door knob assembly. Once you’ve removed it from one side, you should be able to slide it out from both sides at once – keep sliding until all pieces are completely freed from their cutouts (the rose plate will still be attached). Now grab your electric drill with an appropriately sized bit and drill into just far enough into each pin on each side until they all pop free from their housings in the doors cylinder body.

Finally, set aside all pieces (handle assemblies + pins + cylinder body) that make up your old commercial lock and get ready for installation!

Remove the faceplate

To begin, the faceplate of your lock cylinder must be removed. This can usually be done by simply unscrewing the plate around the lock with a screwdriver. In some cases, you may need to use a special tool to remove this part – consult your owner’s manual for specific removal instructions. Once the faceplate is removed, carefully note its placement before setting it aside. You may need to refer back to it in order to reinstall the lock later.

Remove the Cylinder

Removing a commercial door lock cylinder without a key can be done with just a few tools. In this article, we’ll explain how to effectively and safely remove a commercial door lock cylinder without a key. The process involves a few simple steps, and it’s important to follow the instructions carefully in order to ensure you don’t damage the lock or cylinder. Let’s get started.

Unscrew the cylinder screws

Unscrewing the cylinder screws on the inside of the door is one way to remove a commercial door lock cylinder without a key. Without a key, you will not be able to open the lock from outside. Therefore, most locks that require a removal of the cylinder must first be opened from inside so that you can access the screws on the back of the lock. These are typically Phillips or flathead screws and, depending on your cylinder type, you may need specific tools to remove them, such as screwdrivers or hex wrenches. Once these screws have been removed you will be able to pull out and detach the faceplate and then slide out the cylinder housing. When reassembling your lock remember to lubricate all moving parts before replacing any hardware and make sure everything fits correctly before tightening up any hardware.

Remove the cylinder

Removing a commercial door lock cylinder without a key can be a tricky situation. The cylinder is the part of a keyed lock that holds the tumblers, latch, and other components of the locking mechanism. It’s an essential piece to making sure your door is secure. Removing a locked door cylinder without a key requires proper knowledge and tools so as not to cause any damage.

Before starting, make sure that you have all of your necessary equipment (screwdrivers, pliers) readily available. You may need to purchase specialized tools to remove the lockset depending on its size and type.

The first step when removing the lock cylinder is to take out the screws that join the backplate to the door frame or jamb, taking care not to lose any loose parts in this process. Depending on how long it has been since it was installed you may find it difficult to undo these screws as rust sets in and seizes them up over time. You may need lubricant such as WD-40 in order for them come apart easier. Once you’ve got the screws out you will then be able to remove the interior part of your lockset usually consisting of two pieces; thumbturn mechanisms and latch/lock mounting plates, both held together by screws which will require either a Phillips or flathead screwdriver depending on their shape and size.

Once these are removed you should be able to access the backside of your commercial lockcylinder with ease; here you should be able to unscrew any hex bolts with an Allen wrench (hex key). Once this is done simply pull out the remaining bolt(s) with force making sure that no pieces remain inside after removal (This will help prevent potential damage when installing or re-keying). With everything now taken apart it’s time for your last steps: clean and lubricate each component thoroughly before replacing them in exactly their original positions so that they operate smoothly together when everything is put back together again!

Remove the retaining clip

Removing a commercial door lock cylinder without a key is relatively simple and can be done in just a few steps. The first step to removing the cylinder is to locate the small spring-loaded retention clip. This clip is usually located near the front lip of the cylinder and holds it securely in place, preventing it from turning or being pushed out of the door lockset. To remove this clip, use a pair of needle nose pliers to push down on the lip while pulling outward on the cylinder. Once you have pulled most of it out, use your fingers to remove the remaining portion.

Replace the Cylinder

Replacing the cylinder in a commercial door lock is an effective way to get access to an area without a key. The process is not overly complicated, but it is important to be prepared and have the right tools for the job. This guide will go over the materials and steps needed to successfully replace a commercial door lock cylinder.

Install the new cylinder

Once you have successfully removed the old cylinder from the commercial door lock, it’s time to install a new one. Before doing so, make sure to check that all of the parts that were removed from the old cylinder match up with those of the new one in size, shape, and other specifications. If there are any discrepancies, find a replacement which is more appropriate.

When ready, place the new cylinder into the lock. Make sure it is securely in place and not able to move around or rotate at all. The screws that secure the cylinder should be either tight or totally removed as necessary. If there is a notch on your cylinder where you can insert an Allen wrench or other small tool to secure it further, use this option too – it should create a snug fit and provide additional security for your commercial door lock. Once complete, test that your new lock functions properly before affixing it fully closed with screws or any other applicable method of installation.

Install the retaining clip

Once you’ve inserted the new lock cylinder into the housing and secured it with the set screw, it is important to install the retaining clip. The retaining clip ensures that your new cylinder remains in place, as well as preventing unauthorized access to your property. To install the retaining clip, slide one end of the clip into its slot on the lock cylinder near the keyhole. Push down lightly on the clip with a knife or other flat instrument until it snaps in place around the cylinder. Make sure all sides of the clip are securely locked into place before continuing.

Reinstall the faceplate

Once you have the new lock cylinder installed in your door, it is time to replace the faceplate. Reattaching the faceplate is a very easy process. Begin by locating the retaining clips on the outside of lock body. These clips are what hold your faceplate in place and they can be loosened and tightened with a flat head screwdriver.

Next, lift your new cylinder into the lock body so that it rests against the locking plate. Align the tabs on your retaining plate with their respective slot on your new cylinder and press firmly to secure it in position. Make sure that all 4 pins are fully extended before continuing to reattach your faceplate.

Once you have properly aligned and secured both components, use your screwdriver to tighten all four of the retaining clips and insert a new screw if available for installation of an additional clip at each corner of the lock body for extra stability or security (depending on model). You can then insert and turn any applicable key or instruments to test operation before reinstalling any external decorative elements such as rosettes or escutcheons. Your cylinder is now ready for use!

Reinstall the Door Knob

Once you’ve removed the door lock cylinder from the door knob, the next step is to reinstall the knob. This is a fairly easy process as long as you have the right tools. You’ll need to have a flat blade screwdriver, a phillips head screwdriver, and a set of keys that fit the new door lock cylinder. With all the right tools, you can easily reinstall the door knob and secure your home or business.

Reinstall the door knob

Once the lock cylinder has been removed, re-installing the door knob is necessary in order to complete the process of changing a commercial door lock. Before reinstalling, you’ll need to replace the existing lock cylinder in the new knob if doing a complete change. Most door knobs have a small set screw that keeps it in place, make sure you replace this set screw before continuing with other steps.

Begin by attaching the spindle to its connecting point on one side of the assembly and insert both pieces through the hole. Tighten one side first, sliding over any securing pin if required. Then tighten up both sides evenly so that there are no gaps between them when secured shut locked position. This is generally accomplished using two screws or bolts which are usually located inside on each side.

Attach any additional components such as shallow rosettes or roses, for decorative purposes or for added security. Depending on type and model of your specific door knob, additional pieces may be required as part of installation process such as escutcheon plate or strike plates depending on style and finish chosen for your hardware setup.

Secure all components tightly ensuring proper alignment before opening and closing your newly installed commercial lock cylinder equipped with a new door knob several times to get comfortable with its operation and feel before use.

Secure the door knob screws

The door knob screws need to be securely tightened after the lock cylinder is reinstalled. Forcing the cylinder into an imperfect hole or inadequate clearances can damage it and affect the operation. To avoid this, you must ensure that the door knob screws are securely tightened so that no movement is possible. Make sure to check your fitment from time to time as this may warrant a re-tightening of the screws.

After ensuring that all of your door knob screws are secure, it is important to check that the latch plate fits correctly in its hole and does not protrude too far out. This should give you an even seal with your door jamb, helping make your lock cylinder more resistant to tampering or break-in attempts.
