Rekeying vs. Lock Replacement in Las Vegas: What to Choose

If you’ve just changed tenants, lost a key, or bought a home in Las Vegas, you’re probably facing the same question every property owner eventually asks. Rekeying vs. lock replacement: which one actually fixes the problem? The two get lumped together, but they solve different issues, take different amounts of time, and leave you with a different result on the door. ASAP Security has handled both for homes and businesses across Southern Nevada since 2003, and the short answer is that most situations call for a rekey. Replacement is for a smaller set of cases where the hardware itself is the problem.

Rekeying vs. Lock Replacement in Las Vegas: The Core Difference

Rekeying and lock replacement both end with a lock that your old key no longer opens, which is why the two get confused. What happens inside the lock is different.

• Rekeying removes the existing pins or wafers inside the lock cylinder and replaces them with a new set, cut to work with a new key. The deadbolt, the handle, and the housing you already have stay where they are. Only the internal mechanism changes.
• Lock replacement removes the entire lock (cylinder, housing, and sometimes the strike plate) and installs new hardware from the ground up. This is the option when the lock hardware itself has to change.

Our locksmith services team carries both options on every service call, so which one you need gets decided on-site rather than guessed over the phone.

When Rekeying Is the Right Call

Rekeying covers the majority of the calls we get, because most of the situations that make people think about their locks don’t actually involve damaged hardware. Rekeying is usually the right move when:

• You just moved into a home. You have no way of knowing how many keys the previous owner handed out over the years. Rekeying resets that without replacing hardware that’s probably still in good shape.
• A tenant moved out. Landlords and property managers rekey between every tenant as a standard step in turnover.
• Keys were lost or stolen. A missing key doesn’t necessarily mean the lock is broken. It means the wrong person might have access, and rekeying solves that.
• A relationship, roommate, or employee situation changed. Anyone who no longer needs access can be cut off without touching the lock itself.
• The hardware is in good condition and you’re happy with it. If the lock looks and functions the way you want, there’s rarely a reason to replace it just to change who can open it.

Rekeying is typically faster and more affordable than full replacement, since the locksmith is working with hardware that’s already installed and functioning correctly.

When Lock Replacement Makes More Sense

Lock replacement is the right call when the hardware itself is the problem. Common triggers:

• The lock is damaged, sticking, or showing wear. Southern Nevada’s heat and dust take a toll on lock mechanisms over years of daily use, and a cylinder that’s binding or hard to turn is a replacement issue, not a rekey issue.
• You’re upgrading to a smart lock. Keypad and smartphone-enabled locks are new hardware, not a rekeyed version of your existing deadbolt.
• The door or frame was damaged during a break-in or forced entry. Once a strike plate or door frame is compromised, fixing it usually means new hardware.
• You want to standardize mismatched hardware. Rental properties and older homes sometimes end up with a mix of lock brands and grades over the years. Replacement lets you bring every door to the same standard at once.
• The current lock is a low-security, builder-grade cylinder. If you want a heavier-duty deadbolt for the same door, that’s a hardware change, which means replacement.

Rekeying vs. Lock Replacement: A Quick Comparison

If you’re not sure which column your situation falls into, that’s a normal question to bring to the locksmith on-site rather than decide in advance. A quick look at the hardware usually settles it in a few minutes.

Why Las Vegas Rental Turnover Makes This a Common Decision

Las Vegas has one of the more transient rental markets in the country, so landlords and property managers run into this decision as often as homeowners buying their first house do. Our rental property security checklist covers what a full turnover should include, and rekeying between tenants is one of the non-negotiable steps on that list.

For property managers handling multiple units or an entire community, the scope is usually bigger than a single door. Our guide to property management locksmith services breaks down how rekeying and replacement decisions get made across a portfolio, including when it makes sense to standardize hardware property-wide instead of handling each unit as a one-off.

Professional Rekeying and Lock Replacement vs. DIY

Both jobs look simple from the outside, and rekeying kits are sold at most hardware stores. What’s harder to see from the outside is whether the cylinder is even a good candidate for rekeying, whether the strike plate alignment is contributing to wear, or whether a “sticking” lock is actually a symptom of a bigger door or frame issue.

“Most calls end with a rekey. Replacement comes up when the hardware itself is the issue,” says ASAP Security’s locksmith team.

Most jobs, residential or commercial, are finished in the same visit.

Frequently Asked Questions

Is rekeying as secure as replacing the lock?

In most cases, yes. Rekeying resets the internal pins so old keys no longer work, and the lock body keeps its original security rating. Replacement is worth it when the hardware itself is outdated, damaged, or you’re upgrading to a higher-security deadbolt or smart lock.

How fast can ASAP Security rekey or replace locks in Las Vegas?

Most rekeying and standard lock replacement jobs are completed in the same visit. Larger jobs, like rekeying an entire rental property or replacing multiple commercial doors, can take longer depending on how many locks are involved.

Do you handle rekeying for rental property turnovers?

Yes. We regularly rekey properties for landlords and property managers between tenants, and we also handle eviction lockouts when locks need to change immediately after a tenant vacates.

Can I get a smart lock installed instead of a traditional rekey?

Yes. If you’re already replacing hardware, it’s a good time to consider a smart lock with keypad or smartphone access instead of a standard rekey. Our locksmith team can walk through the options during the same appointment.
