Here's the short answer: changing a door lock in Las Vegas runs roughly $80–$300 per lock, depending on the hardware you choose and whether it's a straightforward swap or a full installation on a new door. That range covers labor and a standard deadbolt or knob set. High-security cylinders, smart locks, or commercial-grade hardware push the number higher. If you're in Summerlin or North Las Vegas and you're saying 'I just moved in and I have no idea who has a key to this place,' keep reading — this post breaks down every cost factor so you don't pay more than you should.
What 'changing a lock' actually means — and why it matters for price
People use 'change the locks' to mean three different things. First, a full lock change: remove the old hardware, install new hardware. Second, a rekey: keep the existing lock, replace the internal pins so the old key no longer works. Third, a lock repair: fix a cylinder that's binding or a deadbolt that won't throw. Each has a different cost. A rekey runs far less than a full swap because the hardware stays put. If your locks are less than ten years old and in good condition, a rekey is almost always the smarter call — same security outcome, lower bill. We'll tell you upfront which one you actually need.
Real cost breakdown: lock change in Las Vegas and North Las Vegas
The table below shows typical price ranges for the most common residential lock work we do across Las Vegas, Henderson, and North Las Vegas. Hardware cost is separate from labor unless noted.
| Service | Hardware tier | Typical range (labor + hardware) | Time on-site |
|---|---|---|---|
| Rekey existing deadbolt | N/A (existing hardware) | $40–$90 per cylinder | ~15 min |
| Standard deadbolt swap | Grade 2 (Kwikset/Schlage) | $80–$160 per lock | ~25 min |
| High-security deadbolt install | Grade 1 (Schlage B60N, Medeco) | $180–$320 per lock | ~35 min |
| Smart lock installation | Schlage Encode, Kwikset Halo | $200–$400 per lock | ~45 min |
| Full re-hardware (3 locks, rekey) | Grade 2 hardware | $240–$420 total | ~1 hr |

What drives the price up — or down
- Hardware grade: a Grade 1 deadbolt costs more than a Grade 2, and smart locks add programming time on top of installation.
- Number of locks: replacing one lock costs more per unit than replacing three at once — the truck is already there.
- Door prep: if the bore hole is the wrong size or the strike plate needs to be mortised deeper, labor time goes up.
- Lock type: a knob-only entry is faster to swap than a double-cylinder deadbolt with a reinforced strike.
- Time of day: after-hours calls carry a service fee — that's true of any legitimate locksmith.
- Your neighborhood: we cover Summerlin, North Las Vegas, Henderson, and everywhere in between, but a job in a remote part of the valley takes more drive time.
The one thing most Las Vegas homeowners don't realize about lock costs
Here's the part most people don't know: the majority of calls we get from homeowners who say 'I need new locks' don't actually need new hardware. A worn cylinder, a misaligned strike, or a key that's been duplicated poorly can make a perfectly good lock feel broken. We diagnose first. If a rekey solves it — and it usually does after a move or a breakup or a roommate situation — that's what we'll recommend. A full lock change is the right call when the hardware is damaged, when you're upgrading from a Grade 2 to Grade 1 for better kick-in resistance, or when you want a smart lock on the front door. Not before. See our full locksmith pricing page for a broader breakdown.
When NOT to hire us — honest talk about door lock changes
If your lock is brand new and you just need a spare key cut, that's a hardware store job — $3–$6, no locksmith needed. If your deadbolt is sticking because the door has swollen from humidity, a locksmith can fix the cylinder but a carpenter fixes the door frame; we'll tell you which problem you actually have. If you're renting, your landlord is legally required to rekey between tenants in Nevada — that's their cost, not yours. And if you're looking at a basic Kwikset knob-set on a storage room and you're handy, a YouTube video and a screwdriver gets it done. We'd rather you spend $0 on something you can handle than pay a service call for it.
Smart locks in Las Vegas — extra cost, real benefit
Smart locks are the fastest-growing request we handle in neighborhoods like Spring Valley and Henderson. The hardware itself — a Schlage Encode or Kwikset Halo — runs $150–$250 at retail. Installation adds labor, and if the door prep isn't already sized correctly, that adds time. The real cost most people miss is the key fob programming mindset: smart locks often need to be paired to a hub or an app, and that step takes a few extra minutes on-site. Budget $200–$400 all-in for a standard smart deadbolt swap, including hardware and labor. That's still far less than a full door replacement, and it gets you a keypad plus remote access.
How to get an accurate quote before anyone shows up
My strong opinion on this: if a locksmith won't give you a price on the phone, hang up. Transparent pricing isn't a courtesy — it's the baseline. The '$19 lockout' bait-and-switch is why the trade has a reputation problem. When you call Rhinox, we ask three things: what's the lock type, what's the hardware situation, and where are you. That's enough to quote a range before we dispatch. We cover all of Las Vegas — from North Las Vegas down Eastern Ave to Henderson and out to Summerlin on the 215. If you're outside our range, we'll tell you that too. No surprises on the invoice. See our 24-hour locksmith page if this is an after-hours situation. For car-related work, our car key replacement page has the same upfront approach.
Neighborhoods we cover — local pricing context
We run trucks across the Las Vegas valley. Summerlin, Spring Valley, Henderson, Green Valley, North Las Vegas, Enterprise, Centennial Hills, Paradise, Seven Hills, Anthem, Mountain's Edge, Southern Highlands, Sunrise Manor, and Whitney Ranch. If you're near Flamingo and Decatur or out past Rainbow toward the 215, we're usually on-site in about 20 minutes. Pricing doesn't shift by neighborhood — the lock type and job scope drive the quote, not your zip code.
