How Much Does It Cost to Rekey a House in Texas? (And Can You Do It Yourself?)
If you’re considering rekeying your home, one of the first questions that comes to mind is simple:
“How much should it cost to rekey a house?”
Whether you’ve just moved in, lost a key, or want better control over who has access to your home, rekeying is one of the most cost-effective ways to improve your security.
In this guide, we’ll break down what you can expect to pay—and whether rekeying your locks yourself is a good idea.
How Much Does It Cost to Rekey a House in Texas?
The cost to rekey a house can vary depending on the number of locks, the type of hardware, and the complexity of the job.
Typical Rekeying Costs in the DFW Area
- Per lock: $20 – $50 per cylinder
- Service call: $75 – $150 depending on location and time
- Average home (3–5 locks): $150 – $300 total
These ranges can vary based on factors like lock type, accessibility, and whether any hardware needs to be replaced.
What Affects the Cost of Rekeying?
- Number of locks – More doors means more cylinders to rekey
- Type of lock – Standard locks vs high-security systems
- Key systems – Master key systems or restricted keyways
- Condition of hardware – Worn or damaged locks may need replacement
In many cases, rekeying is significantly more affordable than replacing all your locks—while achieving the same level of security.
Why Rekeying Your Locks Is a Smart Move After Moving Into a New Home
One of the most important—and often overlooked—steps after moving into a new home is rekeying the locks.
The truth is, you never know who may still have a copy of your keys. Previous homeowners may have shared keys with:
- Friends or family members
- Neighbors
- Contractors or service providers
- Previous Tenants – read our guide on Texas law regarding rental property lock rekeying
Even if you trust the previous owner, there’s no way to account for every duplicate key that may exist.
Rekeying your locks ensures that only you—and those you trust—have access to your home from day one.
It’s a simple, cost-effective step that provides immediate peace of mind and eliminates unnecessary risk.
Can You Rekey Your House Locks Yourself?
The short answer is: yes, it’s possible—but it’s not always recommended.
DIY Rekeying: What to Know
Rekeying a lock involves disassembling the lock cylinder and replacing the internal pins so that a new key works and the old one no longer does.
While DIY rekey kits are available, there are some important risks to consider:
- Incorrect pinning can cause the lock to malfunction
- Small parts are easy to lose or misalign
- Damage to the lock may require full replacement
- Security may be compromised if not done correctly
When DIY Might Make Sense
- You have experience working with locks
- You are rekeying a single, basic lock
- You have the correct tools and pin kits (Texas requires a trade license to perform this service, our license # is B20079)
When to Call a Professional Locksmith
Most homeowners choose professional rekeying because it ensures the job is done correctly, efficiently, and securely the first time.
A locksmith can also:
- Key multiple locks alike (one key for all doors)
- Identify worn or failing hardware
- Recommend security upgrades if needed

Rekeying vs Replacing Locks: Which Is Better?
In most situations, rekeying is the better option.
- Rekeying: Keeps existing hardware, changes the key access
- Replacing: Installs entirely new hardware
If your locks are in good condition, rekeying offers the same level of security at a lower cost.
