Change is good, especially when it comes to your safety. Including changing the door lock. This is a simple task, and takes only a few minutes, but requires your peace of mind. This article will show you how to change the door lock.
Step
Part 1 of 4: Removing the Old Door Lock
Step 1. Determine the key brand you have
It is usually printed on the latch, but can also be found on the lock body. It won't take you long to replace the right lock, as long as knowing the brand, shape, arrangement, and features of the old lock will help you ensure that the new lock looks just right.
Replacing your locks with the same basic brand and style will help ensure that there is no need to modify your door
Step 2. Measure your doorknob
Often, the front and back door lock latches will be larger than the interior lock latches. Knowing the size beforehand will help you avoid buying or installing the wrong one.
- Make a tape measure from the end of the door latch to the center of the doorknob. The best contemporary key hooks are those that measure 6cm with a diameter of 6.5cm.
- The new bolts or latch on many of the new lock latches can be adjusted for both, but be sure to double check before you leave the hardware store so you don't go back and forth.
- Old key hooks may vary in size, but are generally smaller, requiring extensive knowledge of woodworking for this. If that's what you have, try checking into a repair shop for a new lock clasp.
Step 3. Remove the inner knob, if possible
Remove the spring on the doorknob. Then the door knob will come off easily, and you will see the decorative cover. If the button spring cannot be accessed before removing the decorative cover, remove the inner cover first before removing the button spring.
Step 4. Remove the interior decorative cover
The cover screw may not be visible after you release the button. If there is, remove it and store it in an easily accessible place. If it's not visible, look along the edges for any, where they hide a bolt. If there are no intended holes or screws, the plate must be somewhere else. Use a flat screwdriver to remove the cover, it will reveal the locking mechanism.
Step 5. Disassemble the lock section by removing the two inner screws
Remove the screw that secures the inside of the lock to the outside of the lock. Inside you will see some of the knobs. When the screws are removed, you will easily remove some of the knobs from the door.
Do not leave the door closed or you will have to re-insert part of the knob with a "knife", screwdriver, or butter knife to open it
Step 6. Remove the latch assembly
Remove the two screws from the assembly of the door latch on the side of the door. Also remove the lock plate on the frame.
- If your new lock is the same make and model as the old one, you may want to keep the latch plate and lock plate. Compare the new plate with the old one. If the same, it's best to leave it in place if possible. Removing and replacing the screws will cause the grip of the plate to weaken.
- If you can squeeze in with a new screw, you'll need to make one (or two) screw holes first and press them in with the end of the door (a toothpick is best).
- Another alternative is to buy longer screws, but make sure the screw heads are the same as those made by the manufacturer or they won't fit properly and will cause problems.
Part 2 of 4: Replacing With A New Door Lock
Step 1. Install the latch
Smooth out any uneven parts on the latch so that the new latch fits perfectly. Save the new latch in the niche. If the latch fits snugly in the back of the recess, don't worry about adding screws until the rest of the lock fits in.
If the new latch has problems with the latch, screw it into the latch and tighten it
Step 2. Install your new door lock, making sure the eye lock is on the outside
Slide the outside of the lock into the hole, through the latch assembly. Hold it parallel to the floor, insert the inside of the lock, slide it to the outside of the blade of the lock. Insert the screw to be installed, and tighten it all the way down.
Make sure the lock plate is aligned with the new lock. If not, you should replace the lock plate
Step 3. Try operating the latch and locking mechanism with a key
This experiment was carried out with the door open. If something goes wrong of course you don't want to be locked from inside or outside the room.
Step 4. Tighten the remaining screws and check carefully
Your new doorknob should bounce and close easily.
Part 3 of 4: Removing the Old Door Lock
Step 1. Disassemble the locking part by removing the two screws on the outside
This can give you access to the inside of the lock.
Step 2. Use an L wrench to remove the inner screw from the lock
A few quick turns with an L lock should loosen the locking mechanism from the inside. Remove the inner and outer cylinders.
If in the locking screw there is a cover. Use a hammer to loosen the screw head and use pliers to remove the cover. Then use the L wrench to remove the screw
Step 3. If you can't remove the screw using an L wrench, you can use a drill to remove it
This isn't the best option, and requires a fairly strong drill, but it can help to loosen the lock.
- From the outside, drill into the cylinder in the center of the lock where you will find the peg. Remove the peg.
- Alternatively, drill in the two parts of the lock, the top half and the bottom half. Drill through the two sections until the outer cover comes off.
- Insert the screwdriver into the latch and turn the key in the knob.
Step 4. Remove the plus screw on the side of the door to remove the lock
Take the old lock out and clean it of any dirt or dust in the lock recess.
Part 4 of 4: Replace With A New Door Lock
Step 1. Fit and install the new latch into the side of the door
Make sure the top of the lock is facing up. Once adjusted, attach the lock using the two plus screws. Be careful not to over tighten the screws.
After you install the latch on the side of the door, use a screwdriver to test whether the lock is working properly or not
Step 2. Fit the two ends of the cylinder both the outside and the inside into the locking actuator
The two ends of the cylinder are horizontal on one side and circular on the other. Attach the two ends of the cylinder until the flat part touches the other. For ease of installation, install one cylinder first, following the other; installation for both at the same time will feel quite difficult.
Step 3. Install the screws on the inside of the door
Install the screw firmly and firmly, but not too tight so that the lock does not deviate from the center.
Step 4. Check if the lock is working as advertised
Put the key in the lock and turn. See if it plays smoothly. Check if the lock stays in the center.
Suggestion
- Use liquid graphite for your keys. You also don't need to change the keys too often. Use graphite fluid into the lock and where to insert the key an easy way to get the liquid in is to apply it with a pencil.
- The initial equipment price to replace the lock is around Rp. 127,000 to Rp. 254,000 and there is usually a fairly simple plate to open the lock and a few cylinders to change the lock on.
- You can also switch between a “passage” lock (no locking mechanism), a “privacy” lock (the way it is locked by pressing the button in the center of the knob), and the key for inserting the key.
- You can also replace a lock that has a peg with one on the latch there are two parts of the key. Although the use of pegs is more convincing, you can use the one with two or keys to attach to a door or window that is rather large.
- Learn to use only one key. This prevents you from wasting a good key that could still be repaired. Using one key allows you to use one key for all doors on the outside. Several lock companies offer the same lock, which makes this process easier to do on your own.
Attention
- If you have a locker whose locks are both inside and out, then you must keep every key within easy reach in an emergency. It should be easy to find in the event of a fire and you should also make sure everyone in the house knows where the keys are stored. You can also stick it near a fire extinguisher or near a flashlight. Do not release the lock under any circumstances.
- In addition, the key must also be the original, not a duplicate. How many times do you have to shake a duplicate key to open a locked door? Now imagine you are doing it in a room full of fire and smoke. Keep the keys separate according to the door even if the keyhole looks the same.
