Rekey vs Replace Locks in Arlington — 2026 Homeowner Guide
Updated May 12, 2026 · 11 min read
When rekey is the obvious answer
The decisive question isn't "is my lock broken" — it's "do I know everyone who currently has a working key to my home?" If the answer is no, the right move is to rekey, not to replace. The Insurance Information Institute's consumer guidance on home security places "controlling who has keys" as the single highest-leverage residential security practice — well above adding cameras or alarms.
Six scenarios where rekey is the right call:
- You just moved into a new-to-you Arlington home. The realtor, the inspector, the previous owners, and every contractor they hired has a key history. Rekey same-day after closing.
- You lost a key in a non-secure context. Dropped at a public location, missing wallet, suspected pickpocket. The lost key may already be in someone's pocket — assume the worst.
- You fired a service provider with key access. Cleaning service, contractor, neighbor watering plants, dog walker. Rekey same-day after terminating the arrangement.
- You went through a divorce, separation, or roommate change. Estranged former co-residents are statistically the highest-risk source of unauthorized re-entry, per FBI Uniform Crime Reporting data.
- You suspect duplicate keys exist. "Do Not Duplicate" markings on hardware-store keys don't legally bind anyone — the FTC consumer-protection guidance notes that copy enforcement is informal at best.
- You're closing on the sale of a property. Standard real-estate practice: rekey before handing over keys to the buyer to reset the security baseline.
When replace is the right call
Replace makes sense in fewer scenarios but the cost difference is justified:
- The lock is mechanically damaged. Won't latch fully, deadbolt doesn't throw all the way, key sticks. Mechanical failure means rebuild often costs as much as replace.
- You're upgrading from builder-grade. Most Arlington homes ship with ANSI/BHMA Grade 3 hardware — the cheapest tier, vulnerable to common bypass techniques. Upgrading to Grade 1 (commercial-equivalent) requires replacement.
- You're switching lock types. Adding a smart lock, switching from a knob-only door to a deadbolt, adding electronic keypad entry. All require replacement.
- The lock is visibly aged or rusted. Curb appeal and home value. A $90 deadbolt replacement on the front door has resale ROI for the next sale.
- You want master-keying across multiple doors. If existing locks weren't designed for master-keying, replacement with a coordinated set is more reliable than retrofitting.

Grade matters: ANSI/BHMA tiers
Not all locks are equivalent. The ANSI/BHMA grading system rates residential and commercial locks on operational durability, finish, security, and resistance to specific attack types. The grades and their practical security implications:
- Grade 3 (residential, builder default). Tested to 200,000 operating cycles. Limited bump and pick resistance. Common Kwikset 660 / 980 series, default Schlage installations from new-construction builders. Acceptable for low-risk neighborhoods but not the recommended baseline.
- Grade 2 (heavy-residential / light-commercial). Tested to 400,000 cycles. Better bump resistance. Schlage B60/B80 series, Kwikset Signature series. Recommended baseline for the front door at minimum.
- Grade 1 (commercial-equivalent). Tested to 800,000 cycles. Best bump and pick resistance. Schlage B600, Medeco M3, Mul-T-Lock. The Insurance Information Institute's home security guidance specifically recommends Grade 1 hardware for high-value homes and short-term rentals.
The FBI's Uniform Crime Reporting program categorizes residential burglary methods; the data consistently shows "no forced entry" (use of an existing or duplicated key, or unlocked door) as the largest single category nationally. That's exactly the threat model rekeying addresses — and rekeying any grade of lock is enough to neutralize.
Smart locks in 2026: what to choose
Smart-lock adoption in Arlington has grown sharply through 2024-2026 driven by short-term rental demand and home-automation expansion. The four practical categories:
- Keypad-only smart locks (Schlage Encode, Kwikset SmartCode). $130-$220. PIN entry, no Wi-Fi required. Best fit for homeowners who want to eliminate physical keys without a connected-home commitment.
- Wi-Fi smart locks (August Wi-Fi, Yale Assure SL). $200-$350. Remote management, audit logs, guest codes. Most popular for short-term rentals and homes with frequent service-provider access.
- Z-Wave / Zigbee hub-paired (Yale Real Living, Schlage Connect). $180-$320. Requires a smart-home hub (Hubitat, SmartThings, Ring Alarm). Best for homes already running connected-home infrastructure.
- Apple HomeKit / Google Home / Amazon Alexa native. $250-$450. Direct voice and ecosystem integration. Highest convenience, but locked into the platform.
The Federal Trade Commission's consumer guidance on IoT security recommends: changing default credentials immediately, enabling two-factor authentication on the manufacturer app, keeping firmware up to date, and verifying the manufacturer's data-handling policy before purchase. These four steps are more impactful than which brand you choose.
Master-keying for property managers
If you manage multiple Arlington-area properties (rentals, commercial, short-term), a master-key system is a major operational improvement. The arrangement: each property gets its own change key, and a master key opens all of them. Sub-master keys can open subset groups (e.g., one master for all properties in the southwest cluster, another for the north cluster).
Setup cost: $40-$75 per cylinder rekey to a coordinated keyway plus $80-$120 system design fee. ROI calculation: a property manager carrying 15 individual change keys versus 1 master key saves dozens of hours per year in key-handling labor. The Insurance Information Institute notes that managed-property insurance discounts may apply when verified key-control systems are in place.
Real-world example
Customer in Mansfield, March 2024: family just closed on a 4-bedroom resale home. Realtor casually mentioned the previous owners had given keys to "a few people over the years." Customer was quoted $1,420 by a chain locksmith for "complete lock replacement on all 6 entries" with mid-grade Schlage hardware. Customer called a mobile rekey service for a second opinion. Tech rekeyed all 6 existing cylinders (the locks were Grade 2 Schlage, already adequate quality) for $220 total including service call. Saving: $1,200. Same security outcome.

FAQ
What's the difference between rekey and replace?
Rekey: the existing lock body stays in place; a locksmith opens the cylinder, swaps the internal pin stack, and a new key is cut to match the new pin pattern. Old keys no longer work. Replace: the entire lock body is removed and a new lock is installed. Rekey is the right call for "I want my old key to stop working" without changing the lock's look or grade. Replace is right when the lock is damaged, outdated, or being upgraded.
How much does rekey cost in Arlington in 2026?
Standard residential pin-tumbler rekey: $25-$45 per lock cylinder mobile. Most Arlington homes have 4-6 entry locks (front, back, garage interior, garage exterior, side gate), totaling $100-$280 for a full-house rekey plus a $50-$95 service-call fee. Replace pricing depends on the lock grade — basic deadbolt $40-$80, Grade-1 high-security $90-$220, smart lock $150-$450.
When should I rekey vs replace?
Rekey when: (a) you just moved into a new-to-you home, (b) you lost a key, (c) you fired a contractor or housekeeper with key access, (d) you went through a divorce or roommate change. Replace when: (a) the lock is mechanically damaged or won't close fully, (b) you want to upgrade to a higher security grade (Grade 1 vs the builder-default Grade 3), (c) you're adding smart-lock features, (d) the lock is visibly aged and devalues your home's curb appeal.
How often does the Insurance Information Institute recommend rekeying?
The Insurance Information Institute's consumer guidance on home security recommends rekeying any time you cannot account for every existing key (moves, terminations, separations, losses). Insurance carriers may require evidence of rekeying after a documented break-in for replacement-value coverage on jewelry, electronics, or other policy riders.
Are smart locks more secure than mechanical?
It's complicated. Mechanically, smart locks are usually built around the same pin-tumbler cylinder as a standard deadbolt — so the bump and pick resistance is comparable. The added attack surface is digital: weak Wi-Fi/Bluetooth credentials, default PINs not changed, or vulnerabilities in the manufacturer's app. The FTC consumer guidance on smart-home devices recommends specific hardening steps. For most homeowners, a Grade 1 mechanical with strong key control is more secure than a default-configured smart lock.
Will my homeowners insurance discount apply if I install certain locks?
Often yes. The Insurance Information Institute notes that many carriers offer 2-5% discounts on the homeowner's policy when verified high-security locks (Grade 1 ANSI / BHMA rated) or monitored smart-lock systems are installed. Ask your agent for the verification form before purchase.
What about smart locks for short-term rental properties?
Smart locks pay for themselves quickly on short-term rentals — eliminating physical key handoffs is a major operational improvement. Look for locks with built-in code rotation, audit logs, and integration with platforms like Airbnb or Vrbo. The 2024 AHLA (American Hotel & Lodging Association) data on short-term rentals shows smart-lock adoption past 60% in active hosts because of the manageability advantage.
