Can a Locksmith Rekey Any Lock?

Rekeying a lock means changing the internal pin configuration inside the lock cylinder so that the old key no longer works and a new key is cut to match the new configuration. The hardware itself stays exactly where it is — on your door, in your frame — but the lock essentially becomes brand new from a security standpoint. It's the go-to solution after a move-in, a break-up, a lost key, or any situation where someone has a copy of your key and shouldn't anymore.

Rekeying is not the same as picking a lock open. When a skilled locksmith is called to help you regain access — say, you need someone who can unlock a deadbolt you're locked out of — they use professional tools and verify ownership before doing anything. Once you're back inside, rekeying that same deadbolt is often the logical next step so you know exactly who holds a working key going forward. It's a two-visit problem solved in one appointment.

The majority of residential and commercial locks are designed with rekeying in mind. Here's a practical breakdown of the most common types our team works with in Merrillville and the surrounding Lake County area. Standard pin-tumbler deadbolts — the kind you'll find on most front and back doors — are almost always rekeyable. Brands like Schlage and Kwikset use interchangeable pinning kits, making the process straightforward for an experienced locksmith. Door knob locks, the spring-latch style you find on interior and secondary exterior doors, work on the same pin-tumbler principle and can be rekeyed in minutes as long as the cylinder is in good shape.

The mortise lock deserves special mention because it's both more complex and more secure than a standard deadbolt or door knob lock. Common in older Merrillville homes, commercial storefronts along US-30, and multi-unit buildings, a mortise lock is a complete locking mechanism that fits into a deep rectangular pocket (the mortise) cut into the edge of the door. It combines a deadbolt and a latch in one heavy-duty cartridge. A qualified locksmith can rekey the cylinder of a mortise lock without removing the entire body from the door, preserving the integrity of the installation. Because of the additional complexity and the specialized cylinder it uses, mortise lock rekeying takes more time and skill than a basic deadbolt — and that is reflected in the final quote. Commercial property owners especially benefit from rekeying mortise locks whenever a tenant turns over or an employee departs, rather than replacing the entire costly hardware set.

Not every lock on the market is designed to be rekeyed, and a straightforward answer to 'can you rekey any lock' is: no, not every single one. Certain wafer-tumbler locks — found on older cabinet locks, some low-security door knob locks, and many padlocks — do not have replaceable pins. There is no cylinder to repin, so the only fix is a full lock replacement. Similarly, some smart locks and electronic deadbolts are 'keyless' by design; their security is managed through codes or apps, so traditional rekeying doesn't apply. A trained locksmith can still help by resetting access codes or replacing the module, but it isn't rekeying in the mechanical sense.

Severely worn or damaged lock cylinders also fall into the 'can't rekey, must replace' category. If a key has been forced, the lock has been drilled, or years of use have worn the internal components, trying to rekey it would leave you with an unreliable cylinder. In those cases, a locksmith will walk you through replacement options — and if you've ever wondered whether a locksmith can install a deadbolt, the answer is absolutely yes. Installing a fresh, high-quality deadbolt is a routine service and often the smarter long-term investment when the existing hardware is compromised. Call us at (219) 245-2731 and we'll assess your specific lock on-site before recommending anything.

Getting locked out doesn't follow a schedule, and neither do we. Whether it's 2 a.m. on a Tuesday or a holiday weekend, our emergency locksmith team is dispatched from the Merrillville area to reach you quickly. If you're locked out of your house and wondering how to get into your house if you locked yourself out, the right first steps are practical ones: check all windows and other exterior doors, see if a trusted neighbor holds a spare key, and verify whether a side or garage door is accessible. If none of those work, call a professional rather than attempting to force entry — forced entry damages door frames and hardware, often costing far more to repair than a locksmith call.

Car lockouts are another major part of what we do. Can a locksmith unlock your car? Yes — our mobile team carries the specialized tools to open virtually any vehicle make and model without damage. We also handle key programming for a wide range of vehicles. A common question we get is whether a locksmith can program a Nissan key — and the answer is yes for most Nissan models, including transponder keys and key fobs. It's also worth knowing that for key programming, coming to a locksmith is typically a faster, more convenient experience than scheduling a dealership appointment, and you get transparent up-front pricing before any work begins rather than finding out the cost at pickup. The factors that shape the final price include your vehicle make and model, the type of key required, the time of day, and travel distance to your location — we confirm the exact figure before we start.

Rekeying and lockouts are just a slice of what a full-service locksmith handles. Homeowners and business owners across Lake County who are serious about security often ask us about upgrading beyond standard deadbolts. One of the most impactful upgrades is a quality safe — and the brands that consistently stand out for residential and commercial use are Fort Knox, AMSEC, Browning, and deposit safes designed for cash-handling businesses. Fort Knox safes are built with heavy-gauge steel and pry-resistant doors, offering a level of protection that goes well beyond a typical fire-rated box. AMSEC safes are a favorite among commercial clients who need both fire and burglary resistance in a single unit. Browning safes are particularly popular with homeowners who store firearms and valuables together and want a long-pry-bar attack to be a genuinely futile effort. Deposit safes — front-load or drop-slot models — are essential for any Merrillville retail or restaurant operation where cash is handled daily by multiple staff members. If you're serious about protecting your valuables with top-of-the-line safes, our team can walk you through the right model for your square footage, threat level, and access needs.

On the commercial locksmith side, our services extend to master key systems, access control installation, panic bar hardware, and high-security cylinder upgrades for office and retail spaces. Mortise lock service is a core part of our commercial work — maintaining, rekeying, and replacing these locks for property managers and business owners who can't afford downtime.

Two of the most common questions we field before a job are 'how much does an emergency locksmith cost near me' and 'what is a locksmith call-out fee?' A call-out fee is a base charge that covers a technician being dispatched to your location — it accounts for travel, fuel, and the technician's time in transit. On top of that, the work itself is priced based on what the job actually requires: the type of lock or vehicle involved, whether parts like new pins, cylinders, or keys need to be sourced, the time of day (after-hours and holiday calls reflect the real cost of 24/7 availability), and the distance from our base to your location. We do not quote a price over the phone and then change it at the door. When our technician arrives and assesses the job, they give you an exact figure before touching anything — and you decide whether to proceed. That's the standard we hold ourselves to on every call.

If you've ever searched 'is it cheaper to call a locksmith or dealer' for a car key issue, the comparison really comes down to convenience, speed, and transparency. A dealership may require your vehicle to be towed in, an appointment scheduled, and a wait of days. Our mobile team comes to you, often the same hour you call, and handles most key services on-site. The smart move is to ask for your price confirmation before agreeing to any service — whether you call us or anyone else. With Lake County Pro Locksmith, that confirmation is always part of the process, and there are no hidden fees after the fact.
