When is it necessary to change locks on a home?

New homes can be exciting, but it’s crucial to ensure the safety of your family and belongings. If you don’t change the locks, you might have to rely on the previous owner to give you all the keys or trust that they won’t use them themselves.

It’s best to start fresh. Additionally, if the home is a foreclosure or has been unoccupied for a long time, the locks may be old and worn, making them easier to pick or break. It’s better to be safe than sorry.

What do you need to change the locks on a new home?

First, determine the type of lock you need. There are different types, such as deadbolts, door knobs and smart locks. Check with a professional locksmith or hardware store to find the right one for your home.

Changing locks is a relatively simple process, but a locksmith can help you do the job quickly and efficiently if you’re uncomfortable doing it.

6 easy steps to change locks on a new home

Deadbolts are the most secure lock, but you may also want to consider a smart lock or a door knob lock. Once you have determined the type of lock you need, you can purchase it from a hardware store or a professional locksmith.

How to do it

Measure the size of the existing lock or consult a locksmith or hardware store. Consider the level of security that you want, as well as your budget. Then purchase it from a reputable brand and make sure it fits the door.

2. Remove the old lock

Use a screwdriver to remove the screws on the door lock plate. Remove the lock and any screws that hold it to the door.

How to do it

Insert the key and turn it to the unlocked position. Remove the screws on the plate that holds the lock to the door. Remove the lock and any screws that hold the lock to the door. If you have trouble removing the lock, consult a professional locksmith.

3. Prepare the door

Clean the area where the old lock was located to remove debris, dirt, or dust. You may use a small brush or a vacuum to eliminate anything accumulated in the hole.

How to do it

Insert the new latch into the hole where the old latch was located. Make sure the latch fits snugly into the hole. Use screws to attach the latch to the door. Tighten the screws firmly, but be careful not to overtighten them as this may damage the latch or door.

Once you have installed the new latch, prepare the hole for the deadbolt. Measure the size to ensure that the new deadbolt will fit properly. Most new deadbolts come with a template to mark the hole on the door.

Place the template on the door and mark the center of the hole with a pencil. Use a hole saw to drill the hole for the deadbolt. Make sure it’s deep enough to accommodate the entire deadbolt mechanism.

4. Install the new lock

Now that you have prepared the door, it’s time to install it.

How to do it

Take the new lock and insert the latch into the hole in the door. Hold the lock and insert the screws into the holes on the lock plate. Tighten the screws firmly, but be careful not to overtighten them.

Next, insert the bolt into the hole in the door frame. Hold the lock and insert the screws into the holes on the lock plate. Tighten the screws firmly, but be careful not to overtighten them as this may damage the lock or door.

5. Test the lock

Before completing the installation, you need to test the lock.

How to do it

Turn the keys to lock the deadbolt and try to open the door. If the lock works correctly, the door should remain locked. Repeat the process to unlock the door.

Test the latch by opening and closing the door. Make sure the latch operates smoothly, and the door closes properly. If there are any problems, adjust the latch or lock until everything works correctly.

6. Replace the strike plate

Finally, replace the old strike plate with the new one that came with the lock.

How to do it

Hold the strike plate in place and insert the screws into the holes. Tighten the screws firmly, but be careful not to overtighten them as this may damage the strike plate or door.

With the new lock and strike plate installed, your home is now more secure. Remember to keep the old keys in case you need them in the future.

What is the difference between replacing and rekeying?

If you’re wondering whether you should replace your locks or simply rekey them, it’s important to understand the difference between them.

Replacing a lock involves removing and replacing the entire lock with a new one. This is a good option if you want to upgrade the security of your home or if your existing lock is damaged or old.

Rekeying a lock, on the other hand, involves replacing the lock cylinder so it can be opened with a new key. Rekeying is a good option if you want to keep your existing locks but want to change the keys that open them. It is also a good option if you have lost your keys or are concerned that someone else may have a copy of your key.

How much does it cost to change locks on a new home?

On average, homeowners can expect to pay anywhere from $30 to $300 per basic lock — and more for higher-end or smart locks. If you hire a professional locksmith, you may also need to pay for their time and labor, which can add up quickly.

If you are on a tight budget, doing the work yourself can be more cost-effective. Most hardware stores carry a variety of locks and related tools, and many offer instructional materials or advice on how to install them.
