Whether you've just moved into a new home, lost your keys, or want to upgrade your security, knowing how to change a door lock is essential. In this guide, we'll walk you through everything you need to know, from deciding when it's time to change your locks to choosing the right type of lock and the step-by-step process to get the job done. So, grab your tools and let's get started on making your home a safer place!
When Should You Change Your Door Locks?
Changing your door locks is essential in several situations to ensure the security of your home. Here are some scenarios when you should consider changing your locks:
- Moving into a new home: You never know who might have a copy of the keys from the previous owners.
- Lost or stolen keys: If your keys are lost or stolen, it's crucial to change the locks immediately.
- Break-ins or attempted break-ins: Any sign of forced entry should prompt you to change your locks.
- Old or worn-out locks: Over time, locks can wear out and become easier to pick or break.
- Upgrading to modern security: Smart locks offer advanced features that can enhance your home security.
How to Choose Your New Door Lock
Choosing the right door lock involves considering several factors to ensure it meets your security needs and fits your lifestyle. Here are some key points to help you make the best choice:
1. Security Features
- Look for locks with high-security ratings. The American National Standards Institute (ANSI) rates locks from Grade 1 (highest) to Grade 3 (lowest). Grade 1 locks offer the best security for residential doors.
- Consider additional security features such as anti-pick, anti-bump, and anti-drill protection.
2. Type of Lock
- Deadbolts: These provide the highest level of security. Single-cylinder deadbolts are the most common, while double-cylinder deadbolts require a key for both sides, adding extra security.
- Knob Locks: These are less secure and often used in conjunction with deadbolts. They are suitable for interior doors.
- Lever Handle Locks: These are easier to operate, especially for people with disabilities, and are also commonly used for interior doors.
- Smart Locks: Smart locks offer advanced features such as keyless entry, remote access, and integration with home automation systems. They are convenient and can enhance your home security.
3. Aesthetics and Finish
Choose a lock that matches the style and finish of your door and other hardware. Common finishes include brass, nickel, bronze, and chrome.
4. Budget
Locks come in a wide range of prices. While it’s important to invest in a good quality lock, there are options available for various budgets. Consider your needs and choose the best lock you can afford.
By taking these factors into account, you can select a door lock that not only provides the security you need but also fits seamlessly with your home's style and lifestyle.
Replacing vs. Rekeying
When it comes to changing your door lock, you have two main options: replacing the lock or rekeying it.
Replacing the Lock:
Replacing the lock involves removing the old lock and installing a completely new one. This option is ideal if:
- Changing Lock Types: Sometimes, you may want to switch from one type of lock to another, such as upgrading from a knob lock to a smart lock for better security. For example, the eufy Smart Lock S230 offers reliable security with the added benefit of app control for remote access and monitoring. Similarly, the eufy Video Smart Lock S330 not only provides robust security but also includes a video doorbell for added convenience and surveillance.
- Damaged or Worn-Out Locks: If your existing lock is damaged or showing signs of wear and tear, replacing it with a new one ensures that your door remains secure.
Rekeying the Lock:
Rekeying involves changing the internal pins of the lock so that it works with a new key while keeping the existing lock hardware. This option is suitable if:
- Lost or Stolen Keys: If you’ve lost your keys or they’ve been stolen, rekeying allows you to maintain security without replacing the entire lock.
- Moving into a New Home: When you move into a new house, rekeying ensures that previous owners or anyone with a copy of the old keys can no longer access your home.
- Cost-Effective Solution: Rekeying is generally less expensive than replacing the entire lock, making it a budget-friendly option if the existing lock is still in good condition.

Check the Fit:- Measure the backset (the distance from the edge of the door to the center of the lock hole) to ensure the new lock matches.
- Verify that the new lock fits the existing holes in your door.
- Follow the manufacturer’s instructions to assemble the new lock parts. This often involves inserting the latch mechanism into the door and preparing the knobs or handles.
4. Install the New Lock
Insert the New Latch Mechanism:- Slide the new latch mechanism into the hole on the edge of the door.
- Secure it with screws, making sure it is properly aligned.
- Position the exterior part of the lock so that it aligns with the latch mechanism.
- Insert any necessary connecting rods or pins as per the instructions.
- Place the interior part of the lock on the opposite side of the door, aligning it with the exterior part.
- Insert and tighten the screws to secure both sides of the lock together.
5. Secure the Strike Plate
- Remove the old strike plate from the door frame.
- Position the new strike plate and secure it with screws.
- Ensure it aligns properly with the latch or bolt for smooth operation.
6. Test the New Lock
Check for Smooth Operation:- Turn the handle or knob to ensure the latch operates smoothly.
