For most Las Vegas front doors the right lock is a Grade 1 or Grade 2 single-cylinder deadbolt from Schlage, Kwikset, or Yale, paired with a reinforced strike plate. Installed by 24/7 Locksmith 4U it runs $114 to $230 per lock plus hardware, and the whole job takes about an hour.
That answer covers the typical case. It changes if the door is a rental you cannot alter, a west-facing entry that bakes all afternoon, a sliding patio door, or a house where you want to stop carrying keys altogether. This guide walks through the choices in the order that actually matters: the door first, then the grade, then the type, then the brand.
Start With the Door, Not the Lock
A $200 deadbolt in a hollow door with a half-inch strike plate held by two 3/4-inch screws is a $200 decoration. Before choosing hardware, check three things:
- Door material. Steel and fiberglass entry doors, standard on most homes built in Henderson and East Las Vegas since the 1990s, hold a deadbolt well. Older wood doors in Sunrise Manor and the neighborhoods off Boulder Highway may have split around the bore and need a wrap plate.
- Strike plate and screws. Replace the builder strike with a heavy-duty box strike and drive 3-inch screws into the framing stud. This is the single cheapest security upgrade on any door, and we do it during every deadbolt install.
- Fit. Desert heat swells wood doors and shifts frames on slab foundations. If the current bolt already misses the hole in July, a new lock will too. Fix alignment first; that is a lock repair, typically $48 to $180.
Deadbolt Grades Explained
Residential locks are rated by ANSI/BHMA on how many cycles they survive and how many hammer blows and torque attacks they resist.
| Grade | What it means | Typical hardware price | Use it for |
|---|---|---|---|
| Grade 3 | Builder grade; the lock most tract homes come with | $15 to $40 | Interior or low-risk doors only |
| Grade 2 | Solid residential; 5 hammer blows, 150 in-lb torque | $40 to $120 | Front, back, and garage entry doors on most homes |
| Grade 1 | Commercial strength; 10 hammer blows, 300 in-lb torque | $80 to $250 and up | Main entry, homes with prior break-ins, detached workshops |
If the deadbolt on your door has no grade on the box or the packaging, it is a Grade 3. Upgrading the main entry to a Grade 1 or 2 deadbolt is where most of the security gain is, and it is what our residential locksmith team recommends first on a new-homeowner visit.
Lock Types and Who They Suit
Single-cylinder deadbolt
Key outside, thumb turn inside. The default for every exterior door. Pair it with a matching handle set or a plain passage knob; the knob lock is not the security, the deadbolt is.
Double-cylinder deadbolt
Key on both sides, for doors with glass within arm’s reach of the thumb turn. It stops a burglar from breaking the glass and reaching in, but it also stops you from getting out in a fire without a key. Nevada fire code limits its use; we install it only on doors with an alternate exit nearby and tell customers to keep a key on a hook out of reach of the glass.
Keypad deadbolt
Code entry, no phone, no Wi-Fi. Good for families with kids who lose keys, for short-term rentals near the resort corridor where guest codes change weekly, and for anyone who wants to stop hiding a key under the mat. Schlage BE365 and Kwikset SmartCode 909 are the workhorses. See our guide on resetting keyless entry locks for how the codes are managed.
Smart lock
Keypad plus app control, remote unlocking, and activity logs. Choose Wi-Fi models (Schlage Encode, Kwikset Halo, Yale Assure with Wi-Fi) if you want remote access; Bluetooth-only models are cheaper but only work when your phone is nearby. Two Las Vegas cautions: a lock body on a west-facing door can run far above air temperature in summer, which shortens battery life and occasionally cooks touchscreens, and long single-story houses often need a Wi-Fi extender near the door. A Grade 2 rating still matters here; several popular smart locks are Grade 3 mechanically.
Lever handle vs. knob
A lever is easier for kids, older residents, and anyone carrying groceries, and it is required for accessibility in most new construction. Either way, the handle is convenience, the deadbolt is security.
High-security deadbolt
Medeco, Mul-T-Lock, and Schlage Primus use restricted keyways with controlled blanks, so keys cannot be copied at a kiosk, and the cylinders resist picking, bumping, and drilling. They cost more per lock and the keys are cut only by authorized dealers. Worth it for a home that has been burglarized, a house with valuables or a home office, or a landlord who wants to control key copies. Our guide to lock bumping in Las Vegas explains the attack these cylinders defeat.
Las Vegas Factors That Change the Choice
- Heat and sun. Bright brass and painted finishes fade on doors that face west or south. Satin nickel, oil-rubbed bronze, and stainless hold up better. Use lithium batteries in any electronic lock on a sun-facing door.
- Dust. Fine desert grit collects in keyways and on keypads. Locks with dust covers or shrouded cylinders last longer on doors that face open lots or the wind coming off Sunrise Mountain.
- HOA rules. Many Henderson and Summerlin-style communities specify exterior hardware finishes. Check before buying a bright-chrome smart lock for a community that requires bronze.
- Security screen doors. Common on east side homes. Make sure the screen door lock and the entry deadbolt do not fight each other; a keyed-alike setup lets one key run both.
- Sliding patio doors. The factory latch is not a lock. Add a keyed patio bolt or a security bar; a Charley bar in the track is the cheapest fix.
- Garage entry door. The door from the garage into the house is often the weakest exterior door in the home, because the builder treated it as interior. Give it the same deadbolt grade as the front.
Renting? What You Can Change
Most Las Vegas leases prohibit replacing locks without written permission, and apartment communities around UNLV, Paradise, and Whitney enforce it at move-out. Options that do not alter the lock: a retrofit smart lock that mounts over the existing deadbolt thumb turn (Kwikset Convert, August), a portable door lock for the bedroom, and asking the manager for a rekey at move-in, which many will do on request since it keeps their hardware.
What It Costs
| Job with 24/7 Locksmith 4U | Typical price |
|---|---|
| Install a new deadbolt or handle set (labor, per lock) | $114 to $230 plus hardware |
| Full lock change, hardware included | $54 to $530 depending on the lock |
| Rekey existing locks instead of replacing | $48 to $300 |
| Strike plate and screw reinforcement | Included with a deadbolt install |
| Lock repair or alignment | $48 to $180 |
A $29 service fee covers the visit and you approve the exact quote before work starts. If your current locks are Grade 2 or better and only the keys need to change, rekeying is the cheaper answer and takes 45 to 90 minutes for a whole house.
Quick Recommendations by Situation
- Just bought a house in Sunrise Manor or East Las Vegas: rekey everything on day one, then upgrade the front and garage entry deadbolts to Grade 2 with a box strike.
- Short-term rental in Paradise: Wi-Fi keypad deadbolt with guest codes, Grade 2, lithium batteries, plus a keyed-alike security screen door.
- Family home in Henderson with kids: keypad deadbolt on the main door, lever handles, patio bolt on the slider.
- Home office, prior break-in, or valuables: Grade 1 high-security deadbolt with a restricted keyway on the main entry.
- Apartment near UNLV: retrofit smart lock over the existing deadbolt, portable lock on the bedroom, rekey request to the office.

Choosing a Home Lock FAQ
What is the best deadbolt for a Las Vegas front door?
A Grade 1 or Grade 2 single-cylinder deadbolt from Schlage, Kwikset, or Yale with a reinforced box strike and 3-inch screws. Choose a satin or bronze finish on sun-facing doors. Installation runs $114 to $230 per lock plus hardware.
Are smart locks safe in the Las Vegas heat?
Yes, with two adjustments: use lithium batteries and expect to replace them about twice a year on west-facing doors, and pick a model with a Grade 2 mechanical rating. Touchscreens on doors in full afternoon sun fail sooner than push-button keypads.
Should I rekey or replace my locks when I move in?
Rekey if the existing locks are Grade 2 or better and in good shape; it costs $48 to $300 for a house and keeps the hardware. Replace the main entry and garage entry deadbolts if they are builder-grade Grade 3 units.
Can I install a deadbolt myself?
If the door already has a bore and the new lock matches the backset, yes. If the door needs a new hole, the strike needs mortising, or the bolt does not line up, a professional install at $114 to $230 avoids a door that will not lock in summer when the frame shifts.
Is a double-cylinder deadbolt legal in Nevada?
It is allowed on residential doors in limited cases but restricted by fire code because it can trap occupants. Use it only on a door with glass near the lock and another exit close by, and keep a key on a hook out of reach of the glass.
