One of the most important things to do after purchasing a home is taking steps to keep it safe. For some, this may mean installing security cameras and other safety measures. But as simple as replacing a lock in your home, it can go a long way when it comes to adding an extra layer of security. So, how do you replace the lock in your home? And should you call an expert or is this a potential DIY project? This Redfin article covers all of that.
Why do I need to replace the lock in my new home?
The existing locks in your home probably work well, but for security reasons, it is best to replace them after you move in. If the previous owner loses the key and holds the same lock, the replica may be floating. This can be a problem if you fall into the wrong hands.
It’s also an opportunity to upgrade. You may need a convenient smart lock or a style that matches the curb appeal of your home. Once you have determined what types of locks you need, the process of changing them is simple. Here’s how to do it:
How to change the lock of your home
1. Get stock of all doors that require a new lock
Make a note that there are no doors on your home. Each of these doors requires a new lock, not just the main entrance, so you will need to purchase a new lock for each.
2. Buy new locks and collect tools
When purchasing a new lock, the important details to keep in mind are the brand of the old one. In many cases, different locks from the same brand fit better than locks from other companies.
In terms of tools, this is a relatively simple project. You only need measurement tape to ensure that the new lock fits the opening and that the driver to remove the old lock and install the new lock is secured.
3. Remove the old lock from the door
To remove an existing lock from the door, use a screwdriver to remove the screws that hold it in place. From there, you can remove the outer plate and then open the door to remove the side plate and other components of the lock.
4. Install a new lock on the door
Once the old lock is removed, it’s time to install the new lock. Before you secure it with screws, place dead bolts and other parts in the right place and pay attention to the lock kit instructions.
5. Test a new lock
The new locks are great, but it doesn’t matter if they don’t do the job they’re designed to do. Test each lock after installation. A flawed lock will give you a false sense of security and leave your home vulnerable to intruders. If the lock components appear to be loose or the door is not locked properly, reinstall the lock or call a professional to check out.
6. Make an additional copy of the key for the new lock
After the new locks are installed, simply create keys for those locks. Make sure that everyone who lives in the house with you has a copy of their key.
Pro tips for smoother installation and better security
All keys lock the same lock. Set a new lock on the locksmith or hardware store and use a single key. This makes it easier to get in and out without groping for the right one, especially if you have multiple exterior doors.
Upgrade your strike plate. Not only do the door frames, but also mount a sturdy plate with 3-inch screws that are secured deep into the wall studs. This simple upgrade makes it much more difficult for someone to force open the door.
Keep your old locks and keys. Store them in a labeled bag in case you reinstall them later. This can be useful if you need to move, rent a property, or return your home to its original state.
Check the door alignment first. Doors with insufficient lined doors can prevent smooth operation even with new locks. Look for signs where doors are stuck, deadbolts are not lined up, or where there are extra force to close.
Choose Rekey Friendly Rock. Some brands allow you to rekey at home without replacing the entire lock. This is useful if you want to lose your key, move your tenant, or change your key without purchasing new hardware.
FAQs about changing your home lock
How much does it cost to change the lock in a house?
On average, locksmith services include replacing locks and rekeying costs between $130 and $320.

When do I need to call a professional to change my lock?
If it’s not particularly useful when it comes to DIY projects, it’s probably best to leave this to the pros. Additionally, if you have more complex locks, such as smart locks, self-installation may not be an option.
Do I need to rekey the lock instead of replacing it?
Rekeying the lock or changing the lock mechanism so that the new key unlocks is a cheaper alternative to completely modifying the lock. If you’re happy with the current state of the lock, this is a solid option. However, if the lock on your home is poor, this may not be the best solution.
