Changing Locks on New Home: Rekeying and Costs

Closing on a new house comes with a long checklist, and securing the perimeter is an essential step. When changing locks on new home doors, buyers may wonder whether to replace all exterior hardware. In reality, rekeying existing locks is often sufficient when they are in good condition and is typically less expensive than replacement.^[1]

Whether moving into a newly built home or an existing property, updating your locks helps ensure that prior occupants, past workers, or others with old keys no longer have access. See also Car Key Fob Replacement Cost – 10% Off & Free Estimate – Same-Day Service.

Changing Locks on a New Home: Costs, Options, and Key Takeaways

Securing your entry doors generally involves two primary options: rekeying the existing hardware or replacing the locksets entirely. Rekeying is often sufficient when the existing hardware is functional and undamaged, whereas replacement is better suited for damaged, worn, or outdated locks.

A residential locksmith such as ASAP Locksmith Vegas can alter the internal pin configuration of your current locks so that old keys no longer work, providing a new key that operates your entry points.

When Rekeying Is Often Sufficient

Rekeying is often sufficient when exterior locks are sturdy, undamaged, and functioning smoothly. Choosing to rekey is typically less expensive than full lock replacement and allows you to maintain consistent exterior hardware finishes across entryways.

When Full Lock Replacement Is Recommended

Full lock replacement is generally better when:

• Existing hardware is worn, damaged, sticking, or showing severe weather deterioration.
• Installed locks use incompatible keyways that cannot be rekeyed to a single key.
• You prefer to upgrade to modern finishes, smart deadbolts, keyless entry systems, or higher-security hardware.

How Much Does It Cost to Change Locks on a House?

Rekeying is typically less expensive than purchasing and installing brand-new locksets of comparable quality, making it a practical option for move-in security budgets.

Price Considerations

When hiring a professional like ASAP Locksmith Vegas, total costs commonly include a service fee along with a charge per lock cylinder. Rekeying existing hardware is often substantially less costly than replacing complete handlesets or specialty architectural locks.^[3]

Avoiding Locksmith Scams and Hidden Fees

When searching for a residential locksmith, exercise caution regarding providers advertising unusually low introductory rates. Some operators quote unrealistically low fees to arrive on site, claim hardware cannot be rekeyed, and charge inflated rates for basic replacements.

Look for established, reputable local locksmiths like ASAP Locksmith Vegas who provide transparent estimates based on your hardware and security needs.

When Should You Change Locks After Buying a Home?

Homeowners are generally advised to change or rekey locks shortly after closing. Prior to updating the lock cylinders, it is difficult to confirm who might hold copies of existing keys.

Access Points to Review

During the buying and moving process, multiple individuals may have had access to keys. When securing a new home, consider inspecting all potential entryways, including:

1. Front, side, and rear exterior doors.
2. Garage entry doors and detached building access points.
3. Patio and sliding glass door locks.
4. Exterior gates.
5. Garage door openers and electronic keypads (resetting programming as needed).

Hardware Inspection

A residential locksmith from ASAP Locksmith Vegas can also assess the alignment of doors and strike plates. Correcting misaligned doors ensures deadbolts throw smoothly and securely into the frame, preventing unnecessary wear on hardware.

Frequently Asked Questions

How long does it take a professional locksmith to rekey a new home?

Rekeying a standard single-family home with 4 to 6 entry locks typically takes 30 to 60 minutes. Technicians from ASAP Locksmith Vegas can complete the service on move-in day, testing every cylinder and handing over new keys immediately.

How does the desert climate impact door locks on a newly purchased home?

Extreme heat, UV exposure, and blowing dust can dry out internal lubricants, warp weatherstripping, and cause deadbolts to stick or misalign. ASAP Locksmith Vegas assesses hardware for desert-related wear, ensuring strike plates and heavy-duty locks withstand local climate conditions.

Can different brands of locks on a new house be rekeyed to one key?

Locks can only share a single key if their internal keyways and brands are compatible. If your new home has mismatched hardware, ASAP Locksmith Vegas can replace incompatible cylinders with matching units so one key operates all exterior doors.
