Changing the locks on your new house doors is one of the first tasks you should complete when moving into a new home. It ensures that you're the only one with access to your property, offering both security and peace of mind. In this article, we’ll walk you through the process of changing door locks and explore the benefits of hiring a professional lock change service when necessary.

Why You Should Change the Locks

The first step to ensuring your home is safe and secure is by changing the locks on all external doors. Even if the previous homeowners assured you they have the only keys, there’s no way to verify how many copies of the key were made, or who might still have them. This is especially important if the house was previously rented out or if you’re unsure about who had access to the keys in the past.
By replacing the locks, you ensure that only you (and those you trust) have access to your new home.

What You’ll Need to Change the Locks

Before you begin the lock replacement process, make sure you have the right tools and materials. You can usually purchase everything you need from your local hardware store or online:

• New locks (deadbolts, knob locks, or lever locks, depending on your preference)
• Screwdriver (a Phillips head and flathead screwdriver)
• Measuring tape
• Pen and paper (for taking measurements)
• Drill (only if you need to make new holes in the door)
• Lock installation kit (optional, but can simplify the process)
• Key duplicates (optional, in case you need extra copies)

Steps to Change the Locks

1. Remove the Existing Lock
To start, you’ll need to remove the old lock from your door. Typically, there will be screws on the door knob or the deadbolt. Once the screws are removed, carefully take out the lock hardware.
If you’re dealing with a deadbolt, make sure to remove the screws on both the interior and exterior parts of the lock.

2. Measure the Lock and Door
Before purchasing your new lock, measure the dimensions of your existing lock and the hole in your door. This ensures that the new lock will fit properly without needing extra drilling or adjustments.
Check the backset (the distance from the edge of the door to the center of the lock) and the hole diameter. Most locks are compatible with standard measurements, but it’s important to be sure.

3. Install the New Lock
Once you’ve selected the right lock for your door, it’s time to install it. Start by inserting the new lock hardware into the hole. For a knob lock, align the exterior and interior parts of the lock on either side of the door.
For a deadbolt, install the exterior piece first, followed by the interior part, and ensure that the deadbolt slides smoothly into place. Use screws to secure the lock in position, but don’t over tighten them to avoid damaging the hardware.

4. Test the Lock
Once installed, test the lock to ensure it’s functioning correctly. Insert the key into the lock and turn it to make sure the mechanism works smoothly. Test both the interior and exterior sides of the lock to ensure everything is operating as it should.
If there are any issues, make adjustments as necessary to ensure the lock fits securely and functions properly.

5. Duplicate Keys
Once the new lock is installed and functioning properly, it’s a good idea to get some extra key copies made. This will ensure that you and anyone else you trust have a spare key on hand, in case of emergencies.
Many locksmiths or hardware stores offer key duplication services, so you can easily get extra copies made. Store these keys in a secure place, separate from your primary set, in case you lose one.

When to Hire a Lock Change Service

While changing locks on your own can be a DIY project, there are times when it’s better to hire a professional lock change service. Here are a few reasons to consider hiring an expert:
Complexity of the job: If your door has a unique lock system or requires significant modifications (such as drilling new holes), a professional will ensure the job is done correctly.
Time-saving: If you’re short on time or simply don’t want to deal with the hassle, a lock change service can save you time and effort.
Security concerns: A professional locksmith can ensure that your new locks are installed securely and meet the highest standards of safety.
Key compatibility: If you need to rekey your locks to match a specific key (for example, to have all doors use the same key), a lock change service can perform this task efficiently.

Additional Tips for Lock Security

Rekeying Locks: If you want to keep your existing locks but change the keys, you can opt to rekey the locks instead of replacing them entirely. This involves changing the internal mechanism of the lock so that it works with a new key.
Upgrade to Smart Locks: If you’re looking for enhanced security, consider upgrading to smart locks. These locks allow you to control access remotely, using a smartphone or key fob.
Check the Quality of the Locks: Invest in high-quality locks from trusted brands. Don’t settle for cheap locks, as they can be easier to bypass. Look for locks that have been certified by security organizations.
Don’t Forget the Garage: Many homeowners forget about the garage door when changing locks. Ensure that the garage door and any side gates are also properly secured.
Maintain Your Locks: Periodically inspect your locks to ensure they’re still working properly. Clean and lubricate them to keep the mechanism functioning smoothly.

Conclusion

Changing the locks on your new house doors is a simple and necessary step to take for your safety and security. Whether you choose to do it yourself or hire a professional lock change service, ensuring your locks are updated is one of the most important things you can do when moving into a new home. With the right tools, a bit of patience, and careful attention to detail, you’ll have secure doors in no time. If you’re unsure about doing it yourself, hiring a professional locksmith can guarantee a job well done, providing you with peace of mind and security.
