Most houses install an additional form of security for their door entrance. A deadbolt lock is one of the most widely used traditional security installations, which means replacing them is unavoidable. We will go through some simple steps on how to replace a deadbolt lock in your own home. You don’t have to be a professional to have your deadbolt replaced, all you need to do is read the guide below.
The Three Common Deadbolt Locks
Deadbolts increase security for your doors because they can only be opened by using the right key. It differs from a bolt that is spring-loaded because it requires a significant amount of force to open, especially when we are thinking in terms of a break-in. Before we start discussing how to replace a deadbolt lock, we will quickly go through the components of a deadbolt lock:
- Thumb-latch or Thumbturn – This is mounted on the interior side of your door, and this mechanism allows you to lock and unlock your deadbolt lock.
- Deadbolt – The deadbolt is the piece that ensures your door is locked shut. It is the bolt that extends from the side of your door.
- Turn piece or Tailpiece – This portion of the deadbolt lock extends to the thumb-latch so you can unlock and lock your deadbolt. When you use your key, the tailpiece turns the mechanism of your Thumbturn for operation.
- Keyhole – This is where you insert your key and is situated on the exterior side of your door.
How To Replace Deadbolt Locks
After knowing the three common deadbolt locks, we will go through the steps on how to replace a deadbolt lock of a single and double cylinder type.
- Single Cylinder Deadbolt - This deadbolt lock is the most common type. It is installed inside the door with an interior twist knob and key cylinder on the outer part of the door. Here are the steps on how to replace a single-cylinder deadbolt:
- Move the thumb-latch so that it is not covering the screws. This usually places it at the lock position.
- Unscrew with a standard screwdriver. This usually takes a bit of time.
- Remove the parts of your deadbolt lock.
- Unscrew the side of your door to remove the single cylinder deadbolt.
- Make sure to clean any residue where your deadbolt lock used to be.
- Open your new single cylinder deadbolt lock purchase.
- Position your new single-cylinder bolt on the side of your door. Make sure you position it the correct side up.
- Screw in the deadbolt lock on the side of your door.
- Position your turn piece so that it seamlessly extends to the other side of the door. Tip: Test the turn piece by inserting your key and observing the mechanism.
- Now that you have your turn piece in place, you can mount your thumb- latch. Tip: Insert the bolts of your thumb-latch, so you don’t have difficulty with alignment later on.
- Screw the bolts of your thumb-latch in place.
- Do another test with your key now that the entire deadbolt lock is in place. If all is working well, you’re good to go!
- Double Cylinder Deadbolt – This type of deadbolt does not have a thumb-latch on the interior side of your door. A key is required for both sides of your door to unlock or lock a double cylinder deadbolt. This type makes it impossible for burglars who try to access it from an opening on the side. But because it takes more time to open, it would also mean a bit more difficulty getting out of the house. The steps are relatively similar to replacing a single cylinder deadlock, except both sides of the door will have a plate with a keyhole. These are the steps on how to replace a deadbolt lock with double cylinders:
- Unscrew the bolts of your lock. These bolts hold in the plate of your lock, which covers the inner layer of your lock.
- Remove the plate/ face of your lock. Be careful not to scratch the surface while trying to remove it.
- Unscrew the bolts located in the inner part of the lock. They may look like cylinders, but they are screws. These two inner bolts (double cylinders) hold both sides of your lock together. Then you can remove both of the turn pieces, leaving behind your bolt.
- Remove your deadbolt by loosening the screws.
- Replacement is in reverse order. Place in the new deadbolt first and screw it in tightly.
- Position the two inner bolts of your turn piece and screw them in place.
- Screw in the plate of your lock to cover your lock.
- Test the lock with your keys on both sides of the door.
- Keyless Deadbolt – A keyless deadbolt lock merely requires a thumbprint or a digital code to lock and unlock the door. This is a modern and relatively hassle-free way of deadbolting your doors. The only replacement needed for these types is battery replacement, which should be easily done with a 4-in-1 screwdriver. The risk of this type is that it will need to be regularly checked because it relies on a battery. It would be a huge inconvenience to be locked out of your own home because of your deadbolt’s battery issue.
