The Retail Lock Trap: Why Brand-New Locks Might Lower Your Security

Many homeowners head straight to a big-box home improvement store when changing locks on new home doors. However, this retail approach can actually lower your overall security. ^[5]

Most off-the-shelf locks sold at retail outlets are Grade 3 residential locks, which is the lowest safety rating. These locks are mass-produced with wide internal tolerances, making them incredibly easy for criminals to bypass using bump keys or basic lock-picking tools. Furthermore, retail locks are often keyed alike in batches, meaning another customer could buy a lock from the same shelf with a key that opens your front door.^[3]

Instead of buying cheap retail replacements, hiring a locksmith to rekey locks you already have is often the safer path. When we rekey your builder-grade locks, we do not just swap standard pins. We can install custom security pins, such as spool or serrated pins, inside the cylinder. These specialized pins catch inside the lock chamber when someone attempts to pick or bump the lock, rendering cheap physical bypass techniques useless. This gives you commercial-grade security using your existing hardware.

How Much Does It Cost to Change House Locks?

The cost to change house locks depends heavily on whether you choose to swap the entire lockset or simply rekey the existing cylinders.

• Full Hardware Replacement: According to 2026 Las Vegas data from local sources like locksmithsprices.com and 702-locksmith.com, the average cost in Las Vegas is $147-$158, with most homeowners spending $90-$270 per lock depending on the quality of the deadbolt. High-security brands like Medeco or Mul-T-Lock will sit at the higher end of this range.
• Professional Rekeying: If you are looking for a cheaper option, the cost to change locks via rekeying is much lower. Matching consistent 2026 local data for Las Vegas, a professional locksmith to change locks by altering the internal pin configuration will typically charge $20-$40 per lock cylinder, plus a standard mobile service fee of $50-$75.

If you need to know exactly how much does rekeying locks cost for your entire house, contact ASAP Locksmith Vegas. We will look at your doors and provide a clear, written estimate with no hidden charges.

Can I Change My House Locks Myself or Should I Hire a Locksmith?

A DIY lock installation seems straightforward, but minor mistakes can leave your home vulnerable. In the Las Vegas valley, extreme summer temperatures cause wooden doors and frames to expand and contract. If a deadbolt or latch is misaligned by even a fraction of an inch, the lock will bind, put stress on the internal mechanisms, and eventually fail, leaving you locked out of your home.

Hiring a professional change door locks locksmith ensures that your hardware is perfectly aligned with the strike plates. A professional can also inspect your door frames to ensure they are reinforced with long, three-inch screws that anchor deep into the wall studs, preventing easy kick-ins. If you decide to handle the physical swap yourself, here is how the process works.

Step-by-Step: How to Change House Locks

If you choose to complete a full physical replacement of your deadbolt, follow these steps:

1. Remove the Old Lockset: Use a Phillips screwdriver to remove the two mounting screws on the interior thumb-turn or knob. Once unscrewed, slide the interior and exterior halves of the cylinder out of the door borehole.
2. Remove the Old Latch: Unscrew the two screws on the edge of the door holding the latch bolt plate in place. Pull the latch mechanism out of the side cavity.
3. Measure the Backset: Use a tape measure to check the distance from the edge of the door to the center of the main borehole. Standard residential doors use a backset of either 2-3/8 inches or 2-3/4 inches. Most modern locksets feature an adjustable latch that can fit both sizes.
4. Install the New Latch: Insert the new latch bolt into the side cavity with the bevel (slanted side) facing the direction the door closes. Secure it flush to the wood using the provided wood screws.
5. Fit the New Cylinder: Guide the exterior keyway spindle through the center of the latch mechanism. Align the interior mounting plate or thumb-turn on the other side, insert the mounting screws by hand to avoid cross-threading, and then tighten them firmly with a manual screwdriver.
6. Test the Alignment: Gently open and close the door several times. Verify that the deadbolt fully extends into the strike plate on the door frame without rubbing or binding. If there is friction, adjust the position of the strike plate on the door frame.

How long does it take a locksmith to change door locks? A licensed professional can complete this entire process in 20 to 30 minutes per door, saving you the frustration of alignment issues and ensuring your manufacturer warranty remains valid.

The Rise of Smart Locks: Modern Convenience and Cybersecurity

Physical keys are no longer the only way to secure a home. The global smart home safety market has grown to $34 billion, driven by homeowners who prefer remote access control, temporary digital keys, and real-time alerts. Modern smart locks let you monitor who enters and exits your home directly from your smartphone.

However, smart locks introduce new variables. Cybersecurity risks with Internet of Things (IoT) hardware now account for roughly 17% of residential tech service calls, according to US national data from SendWork. If you choose to install a smart lock, it is highly recommended by ASAP Locksmith Vegas to select a model that uses local, encrypted protocols (like Z-Wave or Zigbee) rather than basic, unencrypted Wi-Fi connections that are easier to intercept. Additionally, always keep a physical key backup option or a hidden physical override lock cylinder on at least one entry door to avoid lockouts caused by dead batteries or software glitches.^[2]

Frequently Asked Questions

Should you change the locks when buying a new house?

Yes. When changing locks on new house doors, you protect yourself from anyone who previously had access to the property. This includes former owners, real estate agents, cleaning crews, and maintenance workers. Rekeying or replacing these locks should be your very first step upon taking ownership of the keys.

Is it cheaper to rekey or change locks?

It is almost always cheaper to rekey house locks than to replace them. Rekeying only requires changing the small brass pins inside the cylinder, keeping your expensive outer lock bodies, handles, and trim intact. You only need to completely replace house locks if your current hardware is physically broken, worn out, or if you want to upgrade to a completely different style of lock.

What is the difference between rekeying and replacing a lock?

Replacing a lock means removing all the metal hardware from your door and installing a brand-new lockset. Rekeying keeps the existing lock on the door but alters the internal cylinder so that the old key no longer functions and a new key is required. Rekeying is faster, cheaper, and can actually make your locks more secure if a locksmith installs custom security pins inside the cylinder during the process.

Frequently Asked Questions

How does the Las Vegas heat affect my door locks, and how can a professional help?

Extreme desert heat causes wooden doors and frames to expand and contract, which can misalign latch bolts and cause locks to bind or fail. ASAP Locksmith Vegas prevents this by precisely aligning your hardware with reinforced strike plates and installing weather-resistant locks designed to withstand intense temperature fluctuations.

Can I rekey all the different lock brands in my house to work with a single key?

Generally, locks can only be keyed alike if they share the same keyway manufacturer or cylinder type, meaning you cannot easily cross-key a Schlage lock with a Kwikset key. If you want a single-key solution for mismatched hardware, ASAP Locksmith Vegas can replace the incompatible cylinders or install matching high-security locksets across your entire home.

What should I do if my smart lock fails or the battery dies while I am locked out?

If your smart lock lacks a physical key override or the external battery jump-start contacts fail, you will need professional assistance to regain entry without damaging your door. The 24/7 mobile dispatch team at ASAP Locksmith Vegas can quickly bypass malfunctioning electronic locks and restore your home security on the spot.
