Home Rekey & Lock Change

Rekeying and replacing locks are two different procedures that serve the same goal: ensuring that old keys no longer work. When a technician rekeys a lock, they disassemble the cylinder and replace the internal pin tumblers with a new configuration that matches a fresh key. The lock hardware itself stays in place, which is why rekeying is often the faster, less invasive option when your existing deadbolts and door knob lock hardware are in good mechanical condition. A lock change, on the other hand, means the entire lock mechanism — cylinder, housing, and trim — is removed and replaced with new hardware. This is the right call when locks are worn, damaged, outdated, or when you want to upgrade to a higher-security option like a mortise lock, which integrates directly into the door edge and offers superior resistance to forced entry compared to standard cylindrical locks.

The choice between these two paths comes down to the condition and quality of your current hardware, your security goals, and how many doors need attention. A trained technician from A1 Nashville Locksmith will assess every entry point — front door, back door, garage side entry, and any secondary deadbolts — and give you a clear recommendation backed by an exact up-front price before any work begins. Factors that shape the final quote include the type and brand of lock involved (a heavy-duty mortise lock installation, for instance, involves more labor than a standard deadbolt rekey), the number of doors, the time of day your call comes in, and any travel distance within the Nashville service area. There are no hidden fees added after the fact.

Nashville's rental market moves fast — properties in neighborhoods like 12 South, The Nations, and Inglewood turn over constantly, and each time a tenant leaves, key control becomes a genuine liability. Tennessee law does not automatically entitle landlords to verify how many copies a departing tenant made. A rekey lock service is the cleanest way to reset that chain of custody entirely. For homebuyers, the risk is similar: the seller's agent, the inspector, the stager, and any number of service workers may have had a key during the listing period. Changing your locks or rekeying them on move-in day is a straightforward, practical step — not a luxury.

For landlords managing multiple units, we offer master-key system setup so you retain a single operational key while each tenant's unit key works only their own lock. We also handle door knob lock replacements on interior and exterior doors, rekey lock work on sliding door cylinders, and full mortise lock installation on heavier commercial-grade residential doors. If you self-manage properties across Nashville's zip codes — from 37201 downtown to 37221 on the western edge — our mobile lock change service comes to each property individually with no need to bring hardware to a shop. Call (631) 380-4138 and a team member will schedule your service or dispatch an emergency locksmith if the situation is time-sensitive.

A1 Nashville Locksmith handles a wider range of residential lock services than most homeowners expect from a single call. Below is a representative look at what our trained technicians carry and install on a standard residential service run: mortise lock installation and repair, deadbolt rekey for single and double-cylinder locks, door knob lock replacement, keypad and electronic lock programming, Schlage and Kwikset cylinder rekeying, high-security lock upgrades, master key system design and setup, door reinforcement plate installation, strike plate upgrade and realignment, sliding glass door lock replacement, French door multi-point lock service, garage side-entry deadbolt rekey, padlock rekeying and combination reset, intercom-integrated lock wiring support, mailbox lock change, storage unit padlock replacement, window lock installation, chain lock and barrel bolt fitting, door viewer (peephole) upgrade, smart lock Wi-Fi and Bluetooth pairing, keyless entry code reprogramming for Defiant lock change code resets, Honeywell door lock change code and battery replacement guidance, master lock change combination service for built-in luggage and cabinet hardware, lock lubrication and preventive maintenance, broken key extraction without door damage, and full door hardware audit with written recommendations. That list reflects real services performed across Nashville neighborhoods on a regular basis — not a marketing inventory.

Every visit is handled by an insured mobile technician who arrives in a fully equipped vehicle, so there is no waiting on parts to be ordered. For properties with older or non-standard door prep dimensions — common in Nashville's historic bungalows near Five Points or Edgefield — our team carries adapter kits and can modify door prep to accept modern hardware without compromising the door's structural integrity.

Security needs do not follow a 9-to-5 schedule. A1 Nashville Locksmith operates 24/7, which means whether you are locked out at 2 a.m. near Opryland, need an emergency locksmith after a break-in attempt on Charlotte Avenue, or just realized your new rental property's locks were never changed before your tenant moved in this morning, we are reachable and ready. Our mobile units are positioned to serve Davidson County and the broader Nashville metro, and response time is a real priority — not a call-center promise handed off to a subcontractor. When you call (631) 380-4138, you speak with someone who can dispatch a technician and confirm an arrival window immediately.

On the commercial side, our commercial locksmith capability extends to small businesses, multi-unit residential buildings, and mixed-use properties across Nashville. Nashville is home to major corporations — HCA Healthcare, Bridgestone Americas, Dollar General, and others are headquartered here — and the city's dense commercial corridors mean security-grade hardware is not just a residential concern. We install and rekey commercial mortise lock systems, access control hardware, and high-cycle-rated locks built for doors that see heavy daily use. Whether the need is a single office suite off Music Row or a 12-unit apartment building in Donelson, our commercial locksmith services are scoped and priced to fit the specific job, not a flat-rate package that may not match your hardware.

A legitimate mobile locksmith will always ask you to verify ownership or occupancy before performing any lock work — this is a standard professional practice that protects both you and the technician. When our team arrives, expect to show a photo ID and at least one form of proof connecting you to the property: a utility bill, lease agreement, mortgage closing document, or property tax record are all commonly accepted. For landlords performing a tenant-change rekey, a copy of the expired lease is typically sufficient. We will never attempt to verify your identity over the phone in a way that bypasses this on-site check — that step exists for your protection. If you are ever unsure what to bring, call us ahead of arrival and we will walk you through what is needed for your specific situation.

Once verification is complete, the technician performs a quick assessment of your door hardware, confirms the scope of work, and provides an exact quote. Pricing factors include the lock type (mortise lock work carries different labor requirements than a standard deadbolt), the number of cylinders being serviced, any hardware that needs to be sourced from the vehicle's inventory, and the time of day the call was placed. After you approve the quote, the work is performed — typically in under an hour for a standard single-door rekey or lock change — and you receive all new keys cut on the spot. There is nothing to schedule for a follow-up unless you request additional hardware or a master key system review.
