About North Side Locksmith

Being a mobile locksmith means our workshop travels with us. Every van we dispatch is stocked with a working inventory of lock hardware — including mortise lock bodies, cylinders, deadbolts, door knob lock sets, and keyway blanks for a wide range of vehicle makes — so that the large majority of jobs can be completed in a single visit. We do not drive out, assess the situation, and then ask you to wait a second day for parts. We plan our inventory based on the real-world mix of jobs we see in this area, which means we arrive ready.

When you call (847) 200-3477, the process starts immediately. We ask a few focused questions — your location, the type of lock or vehicle involved, and the nature of the problem — so we can dispatch the right technician with the right equipment. We give you a realistic arrival window before we hang up, and we confirm an exact quoted price based on the specifics of your job before any work begins. There are no add-ons invented after the fact, and there is no pressure to approve additional services you did not ask about.

On arrival, the technician introduces themselves, takes a brief look at the situation, and walks you through what they plan to do and why. If anything changes once the work is underway — for example, if a lock cylinder is more damaged than it appeared — we stop, explain the change, and get your approval before proceeding. You stay informed at every step.

The first principle we work from is non-destructive entry. When someone is locked out — whether from their home, apartment, or vehicle — drilling or forcing a lock is almost never the correct first move. Experienced locksmiths have a set of legitimate, professional techniques for manipulating locks without causing damage, and we exhaust those options before any more invasive approach is considered. This protects your hardware, keeps replacement costs lower, and reflects what a qualified technician actually knows how to do.

On pricing, we believe the quote should come before the work, full stop. The factors that go into what a job costs include the type of lock involved (a standard door knob lock is a different scope than a full mortise lock installation), the vehicle make and year for automotive jobs, the time of day, travel distance to your location, and whatever parts are needed. We assess all of those factors on the call and on arrival, and we give you a confirmed number before we start. We do not use vague estimates that balloon once the work is done.

We also believe in leaving a job site the way we found it. Shavings from a re-pin, packaging from a new lock, worn parts we removed — all of that gets cleaned up before we leave. Your door frame, your car interior, your storefront — none of it should look like a work crew came through.

Most customers contact us in one of three situations: they are locked out right now and need immediate help, they have a lock that is not functioning correctly and want it repaired or replaced, or they are proactively upgrading security — rekeying after a move, for example, or switching worn door knob lock hardware for a more robust mortise lock setup. Each situation follows the same basic flow, even if the specific work differs.

You call (847) 200-3477, describe what is going on, and we gather the details we need. For a lockout, that means your exact address and the type of entry point. For a lock replacement or rekeying job, it means the lock brand, door type, and whether you have a preference for new hardware. We give you an arrival window and a price range right on that call, and we confirm the final exact quote on arrival after a quick assessment. Work begins only after you say yes to that confirmed number.

On-site, we work methodically. A residential lockout might involve picking or impressioning the existing lock so nothing is damaged. A mortise lock installation requires removing the old lock body, carefully chiseling or checking the mortise pocket dimensions, fitting and aligning the new mechanism, and verifying smooth operation of the latch, deadbolt, and any thumb turn before we consider the job complete. A rekey involves disassembling the cylinder, repinning it to match a new key, reassembling, and testing multiple times. We do not rush any step — a lock that fails a week later is not a completed job.

Emergency calls are a core part of what we do, and our 24/7 availability is not a marketing phrase — it is the literal structure of how we operate. A lockout at midnight on a Sunday is treated with the same urgency and professionalism as a call at noon on a Tuesday. For residential lockouts, we always approach the situation by first asking about spare keys or secondary entry points, verifying that the person calling has a legitimate connection to the property, and then proceeding with non-destructive entry whenever possible. Lockout services in Skokie are one of the most common calls we receive, and our familiarity with the area means we know where we are going.

Automotive lockout work requires a different skill set and a specific set of tools designed for vehicle entry without damage to door seals, window channels, or locking mechanisms. We work with a wide range of domestic and foreign makes and handle transponder key issues, key fobs, and high-security keys for many modern vehicles. Commercial emergency work — a broken lock on a storefront, a failed mortise lock on an office door, a compromised access point after a break-in — is equally time-sensitive, and we treat after-hours commercial calls as priority dispatches.

Below is a representative picture of the specific services we handle day to day. This is not an exhaustive list, but it reflects the real scope of work our technicians are equipped and trained to manage: residential door lockouts, apartment lockouts, house lock rekeying, deadbolt installation, mortise lock installation and repair, door knob lock replacement, smart lock installation, mailbox lock replacement, lock rekeying after a move or tenant change, sliding door lock repair, window lock installation, garage side door lock installation, car lockouts, car key duplication, transponder key programming, broken car key extraction, car door lock cylinder replacement, ignition cylinder repair, high-security key cutting, commercial door lock installation, commercial mortise lock installation, master key system setup, office rekey services, keypad and electronic lock installation, padlock and hasp installation, storefront door lock repair, and post-break-in security assessment and re-securing.

Commercial locksmith work is its own discipline. Business locks — particularly mortise lock systems — are engineered differently than residential hardware. A mortise lock body sits inside a precisely cut pocket in the door edge and integrates the latch, deadbolt, and often a cylinder on both faces into one unified mechanism. Installed correctly, a mortise lock is exceptionally durable and secure. Installed carelessly, it will bind, fail to latch fully, or wear out prematurely. Our technicians take the alignment, backset measurement, and strike plate positioning seriously because a commercial door that does not lock reliably is a liability.

We also design and install master key systems for property managers, office buildings, and multi-unit residential properties along corridors like Oakton Street and the commercial stretches near Old Orchard. A master key system requires careful planning of the key hierarchy before any cutting begins — which doors each key level opens, how the cylinders are pinned, and how the system scales if new doors are added later. We work through that planning with the property owner or manager before we touch any hardware.

Post-break-in re-securing is another service we provide for businesses. After a forced entry, the immediate priority is making the building secure again — replacing a compromised mortise lock, reinforcing a door frame, or installing higher-grade hardware than what was bypassed. We assess the entry point, explain what failed and why, and present options that make sense for that specific door and risk level.

Residential locksmith work covers a wide range of situations, and two of the most common — and most important — are lock rekeying and lock replacement installation. Rekeying is the process of reconfiguring the pin tumblers inside an existing lock cylinder so that the old key no longer works and a new key does. It is the right move when you have moved into a new home, ended a tenancy, lost a key, or simply want to know that only the keys you personally control will open your doors. Rekeying is generally less disruptive than full replacement because the lock hardware stays in place.

Lock replacement installation makes sense when the existing hardware is worn, damaged, or simply not up to the level of security you want. For front doors, we frequently upgrade from a basic door knob lock — which offers limited resistance to forced entry — to a properly fitted mortise lock or a high-grade deadbolt with a reinforced strike plate and longer throw bolt. For interior doors, the hardware needs are different, and we help homeowners choose appropriately. We install a range of hardware including Schlage, Kwikset, and other quality manufacturers, and we make sure every installation is tested fully before we consider the job done.

Skokie is a dense, walkable community, and many of its homes — particularly in the neighborhoods north of Dempster Street — have older doors with legacy hardware that may not reflect current security standards. We are familiar with the housing stock in this area, and we can assess whether existing hardware is adequate or whether an upgrade makes practical sense, without pushing unnecessary work.
