Las Vegas has one of the most active real estate markets in the country. Thousands of homes change hands every month in Henderson, Summerlin, North Las Vegas, and the surrounding communities. Every one of those homeowners faces the same security question on move-in day: should I rekey or replace the locks?
The honest answer is that for most Las Vegas homebuyers, rekeying is the right choice — faster, cheaper, and just as secure as full replacement. But there are specific situations where replacing makes more sense. Here's how to decide.
What Rekeying Actually Does
A lock cylinder contains a series of spring-loaded pins of different heights. When the correct key is inserted, the pins align perfectly and allow the cylinder to rotate. Rekeying means opening the lock cylinder and replacing those pins with a new set that only aligns with a new key. The lock body, the keyhole, the deadbolt mechanism, and the strike plate all stay exactly as they are.
The result: every old key that ever existed for that lock — the previous owner's keys, the real estate agent's showing keys, the contractor's copies from the renovation three years ago — stops working instantly. Only your new key operates the lock. The security level is identical to installing a brand-new lock of the same model.
What Lock Replacement Does
Replacing a lock means removing the entire cylinder, the lock body, the exterior trim, the interior turn knob or lever, and installing completely new hardware. You get new keys with a new lock. This is more work, takes longer, and costs more — but it's the right choice in certain situations.
When Rekeying Is the Right Call (Most Cases)
If your existing locks are in good condition, operate smoothly, and are a reasonable security grade, rekeying is the right answer. The typical Las Vegas new-home purchase should include rekeying all exterior locks the same day you get the keys. We routinely rekey 3–5 exterior locks at a Henderson or Summerlin home in under an hour for significantly less than a full hardware replacement.
When Replacement Makes More Sense
Replace the locks when the existing hardware is worn, damaged, sticking in Las Vegas heat, or is a low-grade builder model you want to upgrade. Many Las Vegas new-construction homes come with Grade 3 knob locks that offer minimal security. Moving into a home with these? Replacing them with Grade 1 deadbolts is worth the additional cost. You're getting better security and a fresh start simultaneously.
Also replace when you're changing the visual aesthetic — if you're remodeling and want brushed nickel hardware throughout, there's no point rekeying the existing brass locks you're going to replace anyway.
Cost Comparison for Las Vegas Homeowners
Rekeying a standard Las Vegas home with 4 exterior locks typically costs $99–$150 total, completed in one visit. Replacing those same 4 locks with quality Grade 1 deadbolts costs $250–$450 depending on the hardware you choose, plus installation labor. For the security benefit alone, rekeying wins unless you also need hardware upgrades.
