How Much Does It Cost to Rekey a House in Port St. Lucie? (2026)

Rekeying a house is one of the cheapest, fastest ways to feel secure in a new home — but online pricing is all over the place. Here is what a real Port St. Lucie locksmith actually charges in 2026 and what drives the price.

The short answer

For a typical Port St. Lucie home with 3–5 exterior door cylinders, a whole-home rekey runs $125–$225 including the trip charge, new keys and lock lubrication. Per-cylinder rekey pricing is $19–$29 on top of a service call for smaller jobs.

What increases the cost

Higher-security cylinders (Medeco, Mul-T-Lock, Schlage Primus) take longer to pin and cost more per cylinder. Corroded coastal locks near Hutchinson Island sometimes need cleaning first. Homes with 6+ doors, guest houses, mailboxes and pool gates add cylinders quickly.

When to replace instead of rekey

If your locks are builder-grade Grade 3 hardware, showing rust, or don't match, upgrading to Grade 2 or Grade 1 deadbolts often makes more sense than rekeying tired hardware. We tell you honestly on site which path is smarter.

When you should absolutely rekey

After closing on a new Port St. Lucie home, after a roommate or contractor move-out, after losing a key, and any time a spare key is unaccounted for. It's cheap peace of mind.
