Rekey Locks in Billerica, MA
New home in Billerica? Tenant moved out? Keys went missing? Rekeying is the fastest, most affordable way to take full control of who can access your property.
Billerica's real estate market has been active for years — new subdivisions along Route 3A, resale homes in established neighborhoods, and a healthy rental market near Burlington and Woburn. Every property transaction and every tenant change is an opportunity for unknown key copies to exist. Rekeying eliminates that risk in a single visit, without replacing your existing hardware.
Top 5 Reasons Billerica Homeowners Rekey Their Locks
Rekeying isn't just for move-ins. Here are the most common situations that bring Billerica residents to call us — and why each one warrants immediate action.
New home move-in
Whether you're buying a resale home in an established Billerica neighborhood or a brand-new build along the Route 3A corridor, rekeying is the first security step. Previous owners, real estate agents, contractors, and neighbors may all have copies of your current keys.
Divorce or separation
When a relationship ends and someone moves out, rekeying ensures that only the current resident controls access to the home. This is one of the most sensitive and time-critical rekeying situations — we handle it with discretion and professionalism.
Contractor or service worker access
If you gave a key to a contractor, house cleaner, or repair person and the relationship has ended, rekey. You can't be certain how many copies were made or who else may have access. This is especially relevant in Billerica's active renovation market.
Lost or stolen keys
A lost key is a security risk until the lock is rekeyed. If your keys were lost in a public place — a parking lot, a store, or anywhere your address could be identified — rekey immediately. It's far cheaper than the alternative.
Rental property turnover
Billerica landlords with rental properties near Burlington and Woburn know that tenant turnover means rekeying. Massachusetts law and basic security practice both support rekeying between tenants. We service rental properties throughout Billerica on a same-day basis.
How Rekeying Works — and What It Costs
Rekeying is a precise mechanical process that takes minutes per lock and costs a fraction of full lock replacement.
The cylinder comes out
We remove the lock cylinder from the door hardware. The lock body, strike plate, and all exterior hardware stay in place.
Pins are replaced
The internal driver and key pins are replaced with a new set matched to a new key code. Old keys will no longer operate the lock.
New keys cut on-site
We cut your new keys on-site and test each lock before we leave. You're fully secured with working keys in hand.
Keying Alike — One Key for Every Door
One of the most popular requests we get from Billerica homeowners is keying alike — rekeying all the locks in the home so a single key opens every door. Front door, back door, garage entry, and any other exterior locks all operate on the same key. It eliminates the need for a bulky keyring and is especially convenient for families with multiple members who each need a copy.
Keying alike is done in a single visit and costs no more than standard rekeying. We can also key a new lock to match your existing key if you're adding a door or replacing a damaged lock and want it to match the rest of your home.

Rekeying FAQs — Billerica, MA
Do new construction homes in Billerica need to be rekeyed after purchase?
Yes — and this is one of the most important security steps new homeowners in Billerica's growing subdivisions overlook. During construction, builder-grade locks are keyed to master keys used by contractors, subcontractors, inspectors, and real estate agents. You have no way of knowing how many copies of those keys exist or who has them. Rekeying immediately after closing ensures that only the keys you hold work on your new home. It's fast, affordable, and should be done before you move anything in.
How does rekeying work in a Billerica landlord-tenant situation?
Massachusetts law gives tenants the right to change their locks, and landlords are generally not permitted to retain a key to a tenant's unit without consent. When a tenancy ends — whether by lease expiration, eviction, or mutual agreement — rekeying is the responsible step before a new tenant moves in. We work with both landlords and tenants throughout Billerica. For landlords, we can rekey multiple units in a single visit. For tenants, we can rekey your unit and provide you with new keys while ensuring the landlord's access rights are handled appropriately.
Can you rekey high-security locks like Medeco or Mul-T-Lock in Billerica?
Yes, with some important caveats. High-security locks like Medeco, Mul-T-Lock, and Abloy use patented key systems that require authorized dealers and specific rekeying kits. We are equipped to rekey many high-security lock brands, but some proprietary systems require factory-authorized service. When you call, let us know the brand and model of your locks and we'll confirm whether we can service them on-site or need to arrange for a specialized kit.
Does rekeying a lock affect its manufacturer warranty?
In most cases, no — rekeying is a standard, expected service that lock manufacturers anticipate. Schlage, Kwikset, and most other major brands explicitly support rekeying and even sell consumer rekeying kits. However, some high-security brands with proprietary systems may have specific warranty terms around who can perform service. If your lock is under warranty and you're concerned, check the manufacturer's documentation or call us and we'll advise you before proceeding.
How many keys do you cut per lock during a rekey service in Billerica?
Our standard rekey service includes two new keys per lock. If you need additional copies — for family members, a trusted neighbor, or a property manager — we can cut as many as you need on-site at the time of service. Additional keys are priced per copy and are significantly cheaper than having them cut separately later. We recommend deciding on the number of copies before we arrive so we can bring the right key blanks.
