Home Rekey Service

Whether you just closed on a property near the Cranford train station, ended a lease early, or simply cannot account for every copy of your house key, the risk of an unauthorized person walking through your front door is real and immediate. Rekeying directly addresses that risk without the expense of purchasing all-new hardware. Our technicians disassemble each lock cylinder, replace the driver and key pins to a new combination, and reassemble everything so that only the freshly cut key will operate the lock. The old key — and every copy ever made from it — stops working instantly. This is the single most cost-effective way to restore full access control over your home.

Our home rekey service also solves the classic inconvenience of juggling different keys for the front door, back door, side entrance, and garage entry. During the same visit, we rekey every lock in the house to a single master cut, so one key opens everything. Homeowners along the South Avenue corridor in Cranford frequently discover after a move that the previous occupants had multiple locks installed over the years, each with a different key. We consolidate all of them in one appointment, leaving you with a clean, organized access system and the confidence that comes with knowing exactly who holds working keys to your property.

Not all residential locks are created equal, and the type of hardware on your doors directly affects how the rekey process is performed. A standard door knob lock uses a simple pin tumbler cylinder and is the most straightforward to rekey. A mortise lock — the rectangular, pocket-style assembly common in older New Jersey homes and period properties — is a more complex mechanism with a multi-point latch and bolt system built into the door itself. Our technicians are experienced with both formats and carry the tooling and pin kits needed for each. Many homes in Cranford's historic districts still rely on original mortise lock hardware that is decades old, and we handle those with the same care and skill as modern Kwikset or Schlage cylinders.

Beyond door knob locks and mortise locks, we also rekey deadbolts, double-cylinder locks, rim locks, padlocks protecting external gates or sheds, and even certain smart-lock cylinders that use a physical key as a backup. If your home has a sliding door with a keyed lock or a basement access point with a separate cylinder, we include those in the visit so your entire property operates on one unified key. Every lock type we encounter is documented before we begin, and our technician walks you through exactly what will be done and confirms the final price upfront before touching anything — no surprises on the invoice.

Sometimes a standard rekey reveals that the existing hardware simply is not strong enough to protect the home. If a lock cylinder shows signs of wear, tampering, or is a low-grade builder-grade model, our technician will let you know and discuss the option of upgrading to a high-security lock as part of the same visit. We Make Your Property Secure by Installing High-Security Locks including ANSI Grade 1 deadbolts, anti-pick and anti-drill cylinders, reinforced mortise lock assemblies, bump-resistant pin systems, and CISA locks — a respected European-manufactured line with tight tolerances that make unauthorized key duplication and picking significantly more difficult.

CISA locks in particular represent what the industry sometimes calls a CISA s Post configuration — a hardened cylinder post design that resists rotational force attacks better than conventional cylinders. We stock CISA cylinders and can install or rekey them as part of a broader access control upgrade on the same visit. For homeowners who want truly comprehensive protection, we can also install a master key system that allows one key to open all doors while secondary keys open only designated entry points — a solution popular among homeowners who have live-in family members or regular service providers who need limited access. This approach to access control goes well beyond a simple rekey and gives you layered, deliberate security architecture rather than just a lock change.

Once your locks are rekeyed, you may need additional copies of the new key — for a spouse, a trusted neighbor, or a backup set kept in a secure location. Our All-Inclusive Key Cutting Services cover standard house keys, high-security restricted keys, mortise lock keys, and specialty keys for older or less common lock formats. We cut keys on-site at your property using professional equipment, so you do not need to make a separate trip to a hardware store. Keys cut from our mobile unit are precision-matched to the new cylinder profile, reducing the chance of a poorly cut copy causing wear or jamming over time.

Pricing for any rekey or key cutting service at Cranford Locksmith Inc is always quoted upfront and confirmed before work begins — you will never receive a vague estimate followed by a higher number at the end. The factors that go into your final quote include the number and type of locks being rekeyed (a mortise lock takes more time and parts than a basic door knob lock), the time of day the service is requested (our 24/7 availability means some calls occur late at night or on holidays), the distance our mobile technician travels to reach your Cranford address, and whether any parts such as new cylinders, high-security pins, or additional keys are needed. We never use vague bargain language because our goal is transparent pricing and lasting work, not a low number that disappears the moment we open the door. Call 908-357-1225 now and we will give you a clear, confirmed quote before any work begins.
