What Does It Cost to Rekey a House in Port St. Lucie?
The most common question we hear from new homeowners in Port St. Lucie is simple: how much is this going to cost me? For a standard single-family home with three to five keyed entry points, expect to pay between $75 and $150 for a professional rekey service. That breaks down to roughly $20 to $50 per lock cylinder, depending on the lock brand, the complexity of the hardware, and whether you want all locks keyed alike on a single key.
A service call or trip charge is standard for mobile locksmith visits and typically runs $25 to $50 in the Port St. Lucie area. Many locksmiths roll that fee into the total job price when you have multiple locks serviced at once, so it pays to have everything done in a single visit. Rekeying a deadbolt and a knob lock on the same door at the same time is more cost-efficient than scheduling two separate appointments.
High-security lock brands like Medeco or Mul-T-Lock cost more to rekey, sometimes $50 to $85 per cylinder, because their patents restrict key blanks and the pins require specialized tools. Standard residential brands like Schlage and Kwikset are on the lower end of that range and are by far the most common hardware you will find in St. Lucie County neighborhoods.

Rekeying vs. Replacing Locks - Which Is the Better Value?
Rekeying changes the internal pin configuration of your existing lock cylinder so that old keys no longer work. Lock replacement means physically swapping out the entire hardware set - knob, deadbolt, or both. For most Port St. Lucie homeowners, rekeying is the smarter financial choice unless your locks are damaged, outdated, or you want to upgrade to a smart lock or higher-security hardware.
A new entry-level Schlage or Kwikset deadbolt costs $25 to $60 at the hardware store, plus labor to install. Mid-grade options run $80 to $150, and premium smart locks from brands like Yale or Schlage Encode can push $200 to $350 per door. Compare that to a $30 rekey and it is easy to see why most homeowners in communities like Tradition or St. Lucie West choose rekeying when their existing hardware is still in good condition.
There are situations where replacement makes more sense: lock cylinders that are visibly worn or sticky, hardware more than 15 years old, or a move toward keyless entry for a rental property. A licensed locksmith can inspect your current locks and give you an honest recommendation on whether rekeying will hold up or whether a full swap is worth the added investment.
When Should You Rekey Your Port St. Lucie Home?
The number one trigger for rekeying in St. Lucie County is a home purchase. You have no way of knowing how many copies of the previous owner's key are floating around, who contractors or real estate agents gave them to, or whether a former tenant made duplicates. Florida real estate agents are not required to account for every key issued during the listing period, which means rekeying immediately after closing is simply good security practice.
Other situations that warrant a rekey include losing a key, ending a relationship with someone who had access, firing a housekeeper or contractor, or moving into a new rental. Landlords managing properties in areas like Port Salerno or Hutchinson Island often rekey between every tenancy as a liability protection measure. It is a low-cost way to document that a new tenant received a fresh, unique set of keys.
If you have experienced a break-in attempt, even an unsuccessful one, rekeying alone may not be enough. In those cases, a locksmith should assess whether the door frame, strike plate, and lock grade are adequate before assuming a rekey resolves the vulnerability.
What Factors Affect the Final Price?
Several variables influence what you will actually pay when a locksmith shows up to your door in Port St. Lucie. The number of locks is the biggest one. A two-bedroom condo in St. Lucie West with one front entry and a sliding door lock will cost far less than a four-bedroom home in Tradition with a front door, back door, garage entry, and a detached workshop.
- Lock brand and grade: Schlage and Kwikset are standard rate; Medeco and Mul-T-Lock carry a premium.
- Keyed-alike service: Having all locks operate on one key costs slightly more in labor but is often worth the convenience.
- Time of service: Evening, weekend, or emergency calls carry a higher rate than standard business-hours appointments.
- Number of key copies: Additional cut keys are usually $3 to $8 each depending on the key type.
- Restricted keyways: High-security cylinders with patented keyways require special blanks that cost more to source and cut.
Getting a quote over the phone before the locksmith arrives is always a good idea. A reputable, Florida-licensed locksmith will give you a firm price range based on what you describe and confirm the final price before starting work.
Is Rekeying Regulated in Florida?
Yes. Florida Statute 489.516 requires locksmiths to be licensed through the Department of Agriculture and Consumer Services. Any individual or company performing locksmith services for compensation in Florida must hold a valid Class B license. This matters for Port St. Lucie homeowners because it affects liability, insurance, and the legal recourse you have if work is done improperly.
Unlicensed locksmiths operate in Treasure Coast communities and often advertise with unusually low prices online. The risk is not just poor workmanship. An unlicensed person handling your home's keying system has access to your lock brand and cylinder information, which creates a security vulnerability beyond the rekeying itself. Always ask for a license number and verify it on the FDACS website before letting anyone work on your locks.
Licensed locksmiths are also required to carry liability insurance, which protects you if something goes wrong with your hardware during service. This is especially relevant for higher-end lock systems or newly installed smart lock hardware where a mistake during rekeying could damage an expensive cylinder.
