Home Rekeying & Lock Changes

Rekeying is the process of disassembling a lock cylinder and replacing the internal pins so that the old keys no longer work and a new key is cut to match the new pin configuration. It is typically the right call when the lock hardware itself is in solid condition — no damage, no worn cylinder, no outdated mechanism — and the only concern is who holds a working key. A skilled technician can rekey most standard Kwikset or Schlage deadbolts and door knob locks quickly and without damaging your door or frame. The result is a fully functional lock that responds only to the new key, at a fraction of the cost and disruption of a full replacement.

A full lock change, on the other hand, means removing the existing hardware entirely and installing a new deadbolt, door knob lock, or mortise lock assembly. This is the appropriate path when the lock itself has been damaged in a break-in, when the existing hardware is outdated or low-grade, when you are upgrading from a basic knob lock to a mortise lock for significantly stronger security, or when a landlord wants a fresh, documented start between tenants. Our technicians carry a range of hardware and can walk you through the options — grade ratings, keyway styles, finish — and confirm an exact up-front price before touching a single screw. No surprises on the final invoice.

The mortise lock is the gold standard of residential and light-commercial door security. Unlike a cylindrical deadbolt that sits in a drilled hole, a mortise lock is set into a rectangular pocket cut into the door edge, giving it a much larger metal-to-wood footprint and making it dramatically more resistant to kick-in attacks and forced entry. Many of Chicago's older greystone buildings and vintage two-flats — particularly those in Lincoln Square, Pilsen, and Logan Square — were originally built with mortise locks, and over decades those assemblies sometimes get swapped out for cheaper cylindrical hardware. Re-installing a quality mortise lock in those original pockets is one of the most practical security investments a Chicago homeowner can make. Our technicians are experienced with both vintage mortise formats and modern high-security mortise cylinders, and we handle the fitting and alignment to ensure smooth, damage-free operation every time.

For newer construction or doors not designed for a mortise pocket, upgrading from a basic door knob lock to a heavy-duty deadbolt — or adding a second deadbolt above the existing hardware — dramatically increases resistance to common attack methods. Door knob locks alone provide minimal protection; they are designed for privacy, not security. When we assess your entry points, we look at the strike plate depth, the door frame condition, and the hinge hardware, because a Grade 1 deadbolt installed against a weak frame is only as strong as the frame itself. That whole-door perspective is what separates a genuine home rekeying and lock changes service from simply swapping cylinders and walking away.

When you call 773-830-2610, a real person answers — not a voicemail or an automated system. We confirm your address, give you an honest estimated arrival window, and dispatch the nearest available technician. Because we are a fully mobile operation, our vans are stocked with the tools, cylinder blanks, key cutting equipment, and replacement hardware needed to handle most residential jobs on the spot. There is no secondary trip to a warehouse, no waiting on a parts order. For post-move rekeying, we systematically work through every keyed entry point — front door, back door, side gate lock, garage entry, any secondary deadbolts — and can masterkey the results so that a single new key opens everything, or set each lock to its own key based on your preference.

After a break-in, the process starts with a damage assessment before any work begins. If a door frame is split, a deadbolt foot is bent, or a mortise lock body is cracked, we document what is there and explain the repair or replacement options clearly. Our emergency locksmith response is available around the clock precisely because incidents do not follow a schedule — a 2 a.m. call from Andersonville gets the same fully equipped, insured technician as a midday call from Hyde Park or a late-afternoon call from the South Side neighborhoods along the Red Line corridor. We treat ownership verification seriously: we will ask for ID and proof of residency before beginning any work, which is standard practice for any professional, trustworthy locksmith team.

One of the most common questions we hear — especially from callers who have just moved to Chicago from out of state — is some version of: how much does a locksmith cost in Chicago, or how much does a local locksmith charge? The honest answer is that the final price depends on several real variables: the type of lock being rekeyed or replaced (a basic cylindrical deadbolt differs significantly from a high-security mortise lock), the number of entry points being serviced, the time of day (overnight and holiday calls carry different labor costs), travel distance within the metro area, and whether new hardware and parts are needed. What we commit to unconditionally is confirming an exact price before any work begins. If the scope changes — if we open a door and find hidden damage — we stop and discuss it before proceeding. That transparency is non-negotiable.

Knowing how to tell whether a locksmith is legitimate is equally important, especially in a large city where unlicensed operators do appear. Look for a company that has a real local address or service area, answers with a business name when you call, sends a clearly identified technician who shows credentials, provides a written or verbal up-front quote, and asks for ID before working on a home they cannot confirm you own. Lake View Locksmith Chicago checks every one of those boxes. Our technicians are insured, trained, and experienced specifically in Chicago residential and commercial lock systems — including the mortise lock formats common in the city's older building stock. If you ever have questions about what good locksmiths on the South Side of Chicago or anywhere else in the metro should look like in practice, we are happy to talk through it when you call. Reach us any time at 773-830-2610 — we answer 24/7 and we are always happy to explain our process before you commit to anything.

Lake View Locksmith Chicago covers far more than residential rekeying.

Chicago's housing stock is unlike almost any other American city at scale. The three-flat and two-flat greystone construction that dominates neighborhoods from Rogers Park down through Bridgeport means a huge share of the residential lock inventory involves either original mortise lock bodies dating back 60 to 100 years, or mismatched cylindrical hardware that was swapped in during a renovation without accounting for the original door prep. A technician who only works on tract-home cylindrical locks will struggle with a vintage mortise pocket or a steel security door common in South Side bungalows. Our team's Chicago experience means we recognize those situations immediately and have the right tools and hardware on the van. We know the difference between a Belmont Cragin two-flat with an original 1940s mortise pocket and a new-construction condo in the West Loop with a modern cylindrical prep — and we service both correctly.

If you have just experienced a break-in, call the Chicago Police Department first to file a report — you will need that report number for insurance purposes. Once the scene has been cleared and you are safe to re-enter, call 773-830-2610 and our emergency locksmith team will assess the damage and secure the property. Do not attempt to force a bent door lock back into operation or re-use hardware that has been visibly tampered with; compromised lock mechanisms can fail at the worst moment. Our technicians will tell you honestly what can be rekeyed, what must be replaced, and whether any door frame reinforcement is needed before a new lock will hold properly. We can also add a mortise lock or a heavy-duty deadbolt to doors that were only protected by a door knob lock — a common vulnerability our team addresses regularly in older Chicago properties.
