Step-by-Step Guide to Change Locks on Doors

Remove Existing Lock
First,unscrew the screws on the interior side of the lock using a screwdriver. These screws are typically located around the interior plate. Once the screws are removed, carefully pull both the interior and exterior parts of the lock off the door. Be cautious while doing this to avoid damaging the door's surface. -
Remove Deadbolt and Faceplate
Now, focus on the deadbolt and its faceplate, which is secured on the edge of the door. Unscrew the two screws holding the faceplate in place. If the plate is stubborn, use a flat-head screwdriver to gently pry it off. Afterward, pull the deadbolt out of the door edge. Sometimes, you may need to remove additional screws if the deadbolt doesn't come out easily. -
Install New Deadbolt and Faceplate
Take your new deadbolt and place it in the same slot where the old one was. Ensure it fits properly on the edge of the door. If the new faceplate doesn't align with the old cut-out, trace around the new plate with a pencil. Then, use a chisel to carve out the excess wood. Afterward, secure the new faceplate with screws, ensuring it is flush with the door surface. -
Install New Lock Hardware
Next, insert the new exterior lock mechanism (keyhole side) into the deadbolt opening. On the interior side, align the interior mechanism and fit it into place. Be sure that the spindle (the long metal piece) runs through the deadbolt and aligns with the other side. Hand-tighten the screws first to ensure proper alignment before fully tightening them with a screwdriver. -
Install New Strike Plate
Replace the old strike plate on the door jamb with the new one. If the new plate doesn't fit, mark the area with a pencil and gently chisel it to size. Secure the strike plate with screws. -
Test the Lock
Finally, close the door and test the lock by turning the knob and ensuring the latch aligns with the strike plate. Make sure the deadbolt slides in and out smoothly. Open and close the door several times to check the overall function.
By following these steps, you will have successfully installed your new door lock, improving both security and convenience.
When Should You Replace or Rekey a Lock?
Now you know how to get the locks on the door changed. However, you may wonder when I need to replace the door lock or when a rekeying is sufficient. Here’s a breakdown of whether you need a lock replacement or rekeying:
When to Rekey a Lock
Rekeying is a cost-effective option when you want to change the key without replacing the entire lock. This is ideal if you:
- Lose your keys or believe someone may have unauthorized copies.
- Move into a new home or apartment and want to ensure only you have access.
- Want to update security without replacing the hardware.
Rekeying involves changing the pins inside the lock to work with a new key. It’s a good choice when your lock is still in good condition and you just need a new key.
When to Replace a Lock
You should replace your lock if:
- The lock is damaged or no longer functions properly.
- The lock is outdated, and replacement offers better protection or aesthetics.
- You’ve had multiple security breaches, and rekeying won’t provide enough peace of mind.
- You want to upgrade home security and convenience, such as installing a video smart lockwith remote monitoring.
In these cases, it’s more cost-effective and secure to replace the lock entirely, especially if it’s no longer meeting your safety needs.
How to Choose Your New Door Lock
If you're considering a new door lock, here are some key points to help you make the best choice to meet your security needs and fit your lifestyle.
Security Features
Look for a lock with a high-security rating, especially for exterior doors. Deadbolts are essential for securing your door, as they are more resistant to forced entry than spring bolts. If you hope for the utmost security, consider a smart lock with keyless entry, biometric recognition, etc. The eufy Video Smart Lock S330 even provides robust security with a built-in 2K HD security camera and video doorbell for added convenience and surveillance.
Compatibility with Your Door
Measure your door to ensure the lock fits correctly. Most residential doors are between 1 3/8 inches and 1 ¾ inches thick, and the backset (distance from the edge of the door to the center of the hole) is usually 2 3/8 inches or 2 ¾ inches. Be sure to select a lock that matches these dimensions, or you may need to adjust the door.
Aesthetics
Door locks come in various finishes, including brass, chrome, and matte black. Choose a finish that complements your door hardware and fits your home’s style. Some locks also offer decorative features, such as keyhole covers, which can add a touch of elegance.
Ease of Use
Consider the convenience of your lock. Traditional keyed locks are simple but may require physical access, whereas smart locks provide keyless entry, remote control, and even voice activation. Choose a lock that fits your lifestyle and daily needs.
Brand Reputation
Opt for trusted brands known for quality and reliability. Look for locks like the eufy Smart Lock S230 that are BHMA-certified and IP65 water-resistant for durability and security.
