Key Copying & Duplication

Most key duplication happens the way it always has — you drive somewhere, hand over a key, and wait. Lake County Pro Locksmith flips that model entirely. Our mobile units carry precision cutting machines calibrated for standard pin-tumbler keys, dimple keys, high-security mortise lock keys, Schlage and Kwikset profile blanks, padlock keys, cabinet keys, and more. When you call us to a Merrillville address — whether it's a ranch home off Mississippi Street or a commercial suite near the I-65 interchange — we arrive ready to duplicate on the spot, usually in one visit.

Accuracy matters more than speed, though we deliver both. A poorly cut key wears down tumblers over time, stresses springs, and eventually damages the lock cylinder itself. Our technicians use calibrated equipment and verify every duplicated key in the lock before wrapping up the job. That last step — testing the cut key in the actual lock — is something a kiosk machine at a hardware store simply cannot do, and it's one of the most important quality checks in the process.

Mortise locks are the workhorses of commercial and older residential properties across Lake County. Unlike a standard cylindrical lock, a mortise lock sits inside a pocket cut into the door edge, combining a deadbolt and latch into a single robust unit. The keys that operate them — often with distinctive profiles or restricted keyways — require specific blanks and a technician who understands the lock's construction. As an experienced commercial locksmith team, we stock a wide range of mortise lock key blanks and can duplicate or re-cut them without removing the lock from the door.

Merrillville's commercial strips along Broadway and U.S. 30 house everything from restaurants and medical offices to retail anchors that rely on mortise hardware for its durability and security grade. If your business uses mortise lock cylinders on front doors, back-of-house entries, or server rooms, we can supply duplicates for your full key chain — manager sets, staff sets, and emergency spares — with an accurate count and documentation handed off to the keyholder. Call (219) 245-2731 to schedule a commercial duplication appointment or get a same-day mobile visit.

Transparent pricing is non-negotiable for us. Before any work begins, our technician confirms an exact price based on the factors specific to your job: the type of key (standard, high-security, restricted, or specialty profile), the number of copies needed, time of day (our 24/7 availability means some late-night calls carry different logistics), travel distance within our service area, and whether any additional hardware — such as a replacement mortise lock cylinder or a new padlock — is part of the visit. There are no surprise line items added after the fact.

Customers often ask questions like 'How much does it usually cost for a locksmith to unlock your house?' or 'What is a locksmith call-out fee?' — and the honest answer is that both depend on the same variables listed above. A basic key copy during daytime hours at a residential address in Merrillville will be quoted differently than an emergency duplication for a high-security commercial mortise lock at 2 a.m. What never changes is our commitment to telling you the exact number before we touch a single key blank.

Not every key is the same shape, and not every lock deserves a one-size-fits-all approach. Door knob lock keys — the everyday workhorse of residential entries — are among the most commonly duplicated, but they still require the right blank profile and a properly calibrated cut to avoid binding. Padlock keys, especially for heavy-duty outdoor padlocks used on storage units, gates, and utility enclosures, can be trickier because the keyway tolerances are tighter. Our technicians carry blanks for the most common padlock manufacturers and can cross-reference profiles in the field.

We also handle specialty duplication requests that go beyond a standard house key: skeleton keys for antique furniture locks found in older Merrillville homes, cabinet and file-drawer keys for office furniture, mailbox keys for multi-unit residential properties, and restricted-keyway duplicates where the original manufacturer controls blank distribution. In restricted keyway cases, we work within legal ownership verification protocols — we confirm you are the authorized keyholder before any duplication proceeds — so your security is never compromised in the process of serving you.

Key duplication is one layer of security, but it works best alongside physical security for your most important possessions. Lake County Pro Locksmith advises Merrillville homeowners and business operators on pairing strong key control with quality safe storage. We work with top-tier safe lines — including Fort Knox Safes, known for their heavy-gauge steel and multi-layered locking mechanisms; AMSEC Safes, a long-standing benchmark in burglary and fire resistance; and Browning Safes, particularly favored for long-gun and firearm storage. Each manufacturer takes a different engineering approach, and our technicians can walk you through the distinctions so you choose the right unit for your threat model, not just the biggest box that fits the budget.

Deposit safes deserve a special mention for Merrillville's retail and restaurant operators. A through-the-wall or floor-mounted deposit safe lets staff drop cash without accessing the main vault, limiting internal exposure and satisfying many commercial insurance requirements. Whether you need a deposit safe bolted into a back office on Broadway or a Browning firearm safe anchored in a residential garage off 61st Avenue, Lake County Pro Locksmith handles delivery coordination, anchoring, and initial combination setup — all services that complement a solid key management strategy. Think of it this way: a well-duplicated key system controls who enters; a quality safe controls what they can access once they're in.
