How much does it cost to rekey locks in Fort Collins, CO?

Rekeying runs $75–$120 per lock in Fort Collins. Most homes have two to three locks that need rekeying, putting the typical job at $150–$360 total. After-hours calls add $25–$50 to the base rate.

Is rekeying as secure as replacing locks?

Yes — if the existing hardware is in good condition and rated ANSI Grade 1 or Grade 2. Rekeying changes the internal pin configuration so old keys are useless. The only reason rekeying is less secure than replacement is if the hardware itself is worn, damaged, or low-grade.

How long does rekeying take in Fort Collins?

A single lock takes about 15 minutes to rekey. A full house with three locks typically takes 30–45 minutes. A Fort Collins locksmith can usually complete the job in one visit with no special scheduling needed.

Should I rekey or replace locks when moving into a new home?

Rekeying is sufficient for most new homeowners. You don't know how many copies of the original key exist — rekeying immediately solves that problem. Replace the locks only if the hardware is damaged, low-grade, or you want to upgrade to a smart lock or Grade 1 deadbolt.

Do landlords in Fort Collins have to rekey between tenants?

Colorado state law does not currently mandate rekeying between tenants, but it is standard practice and strongly advisable. CSU-area property managers deal with particularly high turnover in August–September and May — most rekey every unit at the end of each lease as a baseline security measure.

What lock brands are worth upgrading to in Fort Collins?

For Grade 1 residential deadbolts, Schlage (specifically the B60N or B62N series) and Medeco are both reliable choices. Kwikset's Titan line offers Grade 1 security at a lower price point. For smart locks, the Schlage Encode and Yale Assure work well with Fort Collins' temperature extremes — cheaper smart locks have had issues with connectivity in very cold weather.

Can a locksmith rekey a lock to match my existing key?

Yes. A locksmith can rekey a new lock to match an existing key — called "keying alike" — so you don't need a separate key for each door. This is a common request for Fort Collins homeowners who want one key for the front door, back door, and garage entry.

How do I verify a Fort Collins locksmith is legitimate before hiring?

Ask for a quote over the phone before they arrive — a legitimate locksmith will provide one. You can also check contractor credentials through Colorado DORA . Avoid any locksmith who won't give a price estimate until they're already on site with your lock dismantled.

Rekeying vs replacing locks Fort Collins: what should you choose and why?

Q: Rekeying vs replacing locks Fort Collins: what should you choose and why?

Rekeying is cheaper and usually sufficient — choose lock replacement only when the hardware is damaged, outdated, or a security upgrade is the goal.

What's the actual difference between rekeying and replacing?

Rekeying changes the internal pins inside the lock cylinder so the old key no longer works. The hardware — the deadbolt, the door prep, the strike plate — stays exactly as it is. A locksmith removes the cylinder, swaps the pin stacks to match a new key cut, and reinstalls it. The whole process typically takes about 15 minutes per lock.

Replacing a lock means removing the entire deadbolt and installing new hardware. You get a new cylinder, new bolt mechanism, and a new key. It takes longer and costs more — but it's the right call when the existing hardware is the problem, not just who has a copy of the key.

When rekeying is the right call

Rekeying makes sense whenever the lock is mechanically sound and the only concern is key control. These are the most common scenarios in Fort Collins:

Moving into a new home — you don't know how many keys the previous owner distributed. Rekeying is the fastest way to secure the property.
Tenancy change — property managers in the CSU and Midtown areas rekey between nearly every tenant. It's cheaper than a full replacement and eliminates the key-control risk.
Lost or stolen key — if a key goes missing and you don't know who found it, rekeying immediately closes that vulnerability.
Consolidating keys — a locksmith can rekey multiple locks to a single key, useful if your home currently runs on three or four different keys.

In Fort Collins, rekeying runs $75–$120 per lock. Most homes need two to three locks done — $150–$360 for a full house, compared to $240–$600 or more to replace every deadbolt.

💡 Tip: Moving into an older home in Old Town Fort Collins? Ask whether the door frames have shifted. Fort Collins temperature swings — from -15°F in winter to 95°F in summer — cause wood frames to expand and contract. A cylinder that rekeyed fine in July can bind or feel stiff by January. That's a frame alignment issue, not a lock issue.

When lock replacement is the right call

There are clear situations where replacing the hardware is worth the extra cost.

The lock is damaged or worn

A deadbolt with a loose cylinder, a sticky bolt, or a keyway that's been forced or picked has compromised internal components. Rekeying a worn cylinder doesn't fix the mechanical problem. Replacement does.

The existing hardware is Grade 2 or Grade 3

ANSI/BHMA grades define deadbolt strength. Grade 1 is the residential benchmark for real security. Grade 2 is standard in builder-grade hardware. Grade 3 is essentially decorative. Many Fort Collins homes built between the 1970s and 1990s — particularly in Midtown and the older Harmony Corridor neighborhoods — were fitted with Grade 2 Kwikset or Schlage deadbolts. Upgrading to Grade 1 hardware such as the Schlage B60N or a Medeco high-security deadbolt means replacing, not rekeying.

You want a smart lock

Installing a smart lock — an August Wi-Fi Smart Lock, a Schlage Encode, or a Yale Assure — requires replacing the deadbolt entirely. Smart lock installation in Fort Collins generally runs $150–$250 in labor, plus the cost of the lock itself ($100–$350 depending on the model). Some smart locks are designed to retrofit existing deadbolts, but most quality models require either a compatible existing deadbolt or a full swap.

⚠️ Watch out: If a key to your lock was copied at a hardware store, rekeying solves the problem. But if the lock uses a patented keyway — like Medeco or Mul-T-Lock — unauthorized copying is already restricted by the manufacturer. Don't pay for replacement hardware to solve a key-control problem that rekeying handles just as well.

What about bait-and-switch locksmiths in Fort Collins?

National franchise operators who appear in Fort Collins search results frequently quote $35–$45 for a service call, then push unnecessary lock replacements once on site — when a simple rekey would do. The Colorado Division of Regulatory Agencies (DORA) handles complaints against unlicensed or deceptive contractors in the state.

Before you book anyone, get a quote before work starts. A legitimate local locksmith will give you a price over the phone or via a quote form — not after they've already dismantled your lock.

In Fort Collins, rekeying runs $75–$120 per lock; deadbolt replacement runs $120–$200 installed. Most homeowners who just moved in, lost a key, or ended a tenancy need a rekey — not a full replacement.
