Home Rekeying & Lockout Entry

Rekeying and lockout entry are two distinct services that are often needed together, and both require a trained hand to execute correctly. Rekeying means a technician disassembles the lock cylinder, replaces the internal pin tumblers with a new combination, and reassembles the lock so that only a freshly cut key will operate it. Your existing hardware stays in place — the deadbolt, the strike plate, the door knob lock, or the mortise lock body — while the mechanical secret inside changes entirely. This is especially valuable in Chicago's dense rental market, where a unit may have changed hands multiple times and unknown copies of old keys could still be in circulation across neighborhoods like Pilsen, Uptown, or Ravenswood.

Lockout entry is the service our emergency locksmith technicians perform when you are physically outside your home and cannot get in. Our approach is always to attempt the least invasive method first — checking secondary entry points, verifying ownership through ID or lease documentation, and using professional pick tools or bypass techniques that leave the lock and door frame completely intact wherever the lock type permits. We never recommend or encourage homeowners to attempt forced entry themselves; an improper attempt can warp a door frame, crack a mortise lock faceplate, or create a gap that compromises weatherproofing during a Chicago cold snap. Leave it to our skilled team and we'll have you inside without a scratch.

Chicago's architectural heritage means a significant share of the city's housing stock — especially two-flats, three-flats, and courtyard buildings constructed between 1900 and 1960 — still relies on mortise lock hardware. A mortise lock is a complete lock mechanism housed inside a rectangular pocket (the mortise) cut into the door edge, combining a latch, a deadbolt, and sometimes additional functions into a single unit. They are robust, elegant, and found on thousands of doors along corridors like Milwaukee Avenue and North Clark Street. However, they require a different rekeying process than the pin-tumbler cylinders inside a standard Kwikset or Schlage door knob lock, and not every technician carries the correct cylinder blanks or has hands-on experience with antique mortise hardware.

Our team is specifically trained in mortise lock rekeying and repair, including sourcing compatible replacement cylinders for older Corbin, Sargent, and similar legacy lock bodies. If a mortise lock is worn, we can also diagnose and repair the internal cam and lever mechanism, replace a broken tailpiece, or install a new mortise cylinder that matches the existing escutcheon plate. When a full replacement is necessary, we carry a range of modern mortise lock sets that meet Chicago building code requirements and integrate cleanly with period-appropriate door hardware. As a core part of our residential locksmith work, mortise lock service is something we perform every single day across the city.

When you call (631) 380-4138, our dispatch team gathers your address, the type of lock you have if you know it, and the nature of the situation — whether it's a lockout, a rekey request, or both. Because we are a fully mobile operation, a trained and insured technician departs for your location without you having to arrange a drop-off or visit a shop. This matters especially in a sprawling city like Chicago, where traffic on the Kennedy Expressway or Lake Shore Drive can make a cross-town trip unpredictable; our technicians are pre-positioned across the metro area to minimize drive time. Before any work begins, we confirm your ownership or tenancy — a standard step that protects you as much as it protects the property — and then present you with an exact, up-front quote. There are no hidden charges added after the job.

The factors that shape your final price include the type of lock involved (a door knob lock rekey is a simpler operation than a multi-point mortise lock service), whether the job is being performed during standard hours or in the middle of the night as an emergency locksmith call, the distance our technician travels to reach you, and whether any replacement parts such as new cylinders or pins are needed. Once you approve the quote, work begins immediately. A typical rekeying of a standard pin-tumbler cylinder takes roughly 15 to 30 minutes per lock. Mortise lock service may take longer depending on the condition of the hardware. When the job is complete, we hand you freshly cut keys on the spot and walk you through any hardware notes before we leave.

An emergency locksmith situation is stressful, and the instinct to force your way in is understandable — but almost always the wrong move. Before calling us, take a breath and run through a quick mental checklist: Is there a spare key with a neighbor, a building manager, or a family member nearby? Is there another door or entry point that is unlocked? Is a roommate or co-occupant reachable by phone? These simple checks can sometimes resolve the situation in minutes without any service call at all. If none of those options pan out, call (631) 380-4138 and our 24/7 dispatch team will get a skilled technician moving toward you right away. Do not attempt to use a credit card, a screwdriver, or any improvised tool on your lock — this risks damaging the mortise lock or deadbolt cylinder in ways that can make professional entry harder and more costly.

Once our technician is en route, stay in a well-lit area if possible, keep your ID or lease documentation accessible for ownership verification, and note any building-specific access issues such as a locked lobby, parking restrictions, or a gate code so we can advise accordingly. Chicago's 24-hour nature — the city that never truly sleeps, from the late-night foot traffic on Division Street to the early-morning deliveries in the West Loop — means lockout situations happen at every hour, and our team is genuinely staffed to respond at 3 a.m. just as effectively as at 3 p.m. An emergency locksmith call does factor into your final quote, as after-hours response involves real operational costs, and we will always communicate that clearly before we begin.
