Why Rekeying Locks Is the First Security Move in a New Home

The benefits of rekeying locks for a new home start with one uncomfortable fact: you have no idea how many copies of your keys exist.

A new home is a fresh start. It is also a security gap.

Who May Still Have Copies of the Old Keys

Most buyers assume there is one key. In practice, a typical home has been through a long chain of hands. Consider who may hold a working copy:

• The previous owners and every family member with a key
• The listing agent and any buyer's agent who showed the home
• Contractors, cleaners, and inspectors who accessed the property
• Neighbors who were given a spare "just in case"
• Former tenants, if the home was ever rented

You cannot collect those keys. You can make them useless. Rekeying a new house changes the lock so every old key stops working the moment the job is done.

Should You Rekey a New House? Weighing the Security Benefits

Yes, rekeying a new house is worth it for most buyers, and the reason is simple: it is the only way to guarantee that no one outside your household can open your doors. The security benefits of rekeying go beyond peace of mind.

Rekeying locks is a security upgrade that resets key control to zero. When we rekey a home, the old keys become obsolete. Anyone holding one finds it no longer turns the cylinder.

The practical wins stack up quickly:

• Unauthorized access ends. No former keyholder can walk in.
• You keep your existing hardware. There is no need to buy new deadbolts if yours are in good condition.
• It is cost-effective. Rekeying reuses the lock body and only swaps the pins.
• One key, every door. We can key all your entry points alike so a single key opens the front door, back door, and garage entry.

Many homeowners find rekeying is the fastest way to close the gap between "new house" and "secure house."

Rekeying vs. Changing Locks: Which One Fits Your Situation

Rekeying and lock replacement solve the same problem in different ways. Rekeying keeps your existing lock and changes the pins inside. Replacement removes the lock entirely and installs a new one. The right choice depends on the condition of your hardware and your security goals.

For most new homeowners, rekeying is the budget-friendly pick. You get new keys and full key control without paying for hardware you already own.

When Rekeying Is Not Enough

Rekeying has limits, and we tell customers this up front. If a lock is damaged, corroded, or was installed poorly, rekeying will not fix it. The same goes for locks that fail a basic security check.

Rekeying is also not the answer if you want keyless entry, remote access, or smart-lock features. In those cases, you are looking at a security upgrade, not a rekey. A good rule: rekey when the hardware is solid, replace when it is not.

The Cost to Rekey House Locks and What Affects It

Most competitors stop at "rekeying is cheaper than replacing locks" and never explain what actually drives the bill. Here is the breakdown we walk new homeowners through before quoting.

Rekeying is priced in two parts: a service call (sometimes called a trip charge) and a per-cylinder labor rate. The service call covers the locksmith's travel and setup; the per-cylinder rate covers the time to remove the core, swap the pins, and test the lock.

What moves the price up or down:

• Number of cylinders. Each exterior door, plus garage entry, basement, and any outbuilding, is a separate cylinder. More cylinders means more per-cylinder charges stacked on one service call.
• Lock type and keyway. Standard residential pin tumbler cylinders (the common Kwikset, Schlage, and Defiant keyways) are quick. High-security cylinders, restricted keyways, and older or off-brand mechanisms take longer and may need pins the truck does not stock.
• Keyed alike vs. master key. Keying all locks to one key is a small add-on because the locksmith is already inside each cylinder. Building a master key system, where one key opens everything and sub-keys open only some doors, adds planning and pinning time.
• Condition of the hardware. A corroded or worn cylinder may need to be removed, cleaned, or replaced mid-job. That is a separate line item, not part of the rekey.
• Timing. Standard business hours are the baseline. Nights, weekends, and holidays typically carry a higher rate, and emergency dispatch can add a premium on top.
• Access and travel. A home with a gated driveway, a long rural approach, or multiple detached structures can add travel or access time.

A common pattern is that homeowners are quoted a low per-lock number over the phone, then surprised by the service call and the keyed-alike add-on. Ask for the full picture up front.

Questions to ask before you book:

615-810-7304 →

1. Is the service call included in the per-lock price, or added separately?
2. Does the per-lock rate cover removal, re-pinning, and reinstallation, or just the pin swap?
3. Is there an extra charge to key all cylinders alike?
4. What happens if a cylinder cannot be rekeyed, is there a diagnostic fee, and how is replacement priced?
5. Are new keys included, and how many?
6. Is there an after-hours or weekend surcharge, and what triggers it?

We do not publish flat prices because every home is different, the number of cylinders, the brands on your doors, and whether you want keyed alike all change the total. Call us at 615-810-7304 for a quote based on your actual doors.

Keyed Alike Locks for a House: One Key for Every Door

Keyed alike locks for a house let one key open every exterior door, which is the upgrade most new homeowners ask for once the rekey is done. Instead of juggling a front-door key, a back-door key, and a garage key, you carry one.

This is where rekeying shines. Because we are already inside the cylinder changing pins, keying multiple locks alike is a small step, not a separate project.

A few things to know:

• Keyed alike means all locks share one key. Simple and convenient.
• Master key systems let one key open everything while giving others limited access, useful for rentals or homes with staff.
• Standardize locks only works if the cylinders are compatible. Mixed brands and old mechanisms can block it.

DIY vs. Professional Rekeying: What You Need to Know

This is the comparison most rekeying articles skip, and it is where new homeowners get into trouble.

What DIY actually requires. A rekey is not a screwdriver job. To change the pins you need:

• A pinning kit with the correct pin lengths for your cylinder's brand and keyway
• A plug follower to push the cylinder plug out without letting the springs and pins launch across the room
• A key gauge or caliper to measure pin lengths against the new key
• The new key cut to the bitting you want, plus a way to confirm it matches the pins you install
• A clean, well-lit workspace with a tray to catch small parts

The catch is compatibility. Pin kits are brand- and keyway-specific. A kit built for one common residential keyway will not fit a different brand's cylinder, and it will not fit a high-security or restricted keyway at all.

Where DIY goes wrong. The common failure modes are predictable:

• Pins installed in the wrong order, so the key turns but the lock is not actually secure
• A lost spring or pin, leaving the cylinder inoperable until replacement parts arrive
• A bent or scratched plug from forcing it back in, which can jam the lock
• A cylinder that was already worn and fails shortly after the rekey, with no warranty behind the work

When DIY is reasonable. If you have a single standard-brand cylinder, the matching pin kit, the right follower, and the patience to work slowly, a one-lock rekey is a legitimate weekend project.

A common pattern we see: homeowners buy two or three trial-and-error kits before calling, and end up spending more than a single professional visit would have cost, with a lock that still needs attention.

A New-Home Rekeying Checklist and Timeline

Rekey within the first week of getting your keys, before you move valuables in. That timeline closes the window when old keys still work. Here is the checklist we walk new homeowners through:

• Day 1: Confirm you have possession and all keys from the seller and agent
• Day 1-3: Walk every entry point and list each lock: front, back, side, garage, basement
• Day 3-5: Decide keyed alike or master key based on how you use the home
• Day 5-7: Schedule the rekey, ideally before move-in day
• Rekey day: Test every lock with the new key and confirm old keys no longer work
• After: Store one spare key in a safe place, not under the mat

Planning the whole property at once, rather than one door at a time, saves a second service call and gets every entry point on the same key.

A new home should feel secure from the first night, not weeks later. If you are not sure who still has a key to your house, that uncertainty is the risk.
