Home Rekey Service

Rekeying is a mechanical process: a trained technician removes the lock cylinder, rearranges the internal pins and springs to a new configuration, and reassembles everything so only new keys operate the lock. The lock body, strike plate, and door hardware stay exactly where they are. For homeowners with quality Schlage or Kwikset deadbolts already installed, this is an efficient way to get new-key security without spending on full hardware replacement. For buildings with legacy mortise lock systems — a hallmark of Chicago's pre-war and mid-century construction — our technicians are specifically skilled in mortise lock disassembly and rekeying, which requires more nuanced work than a standard cylindrical lock and is a core part of what we do every day.

Our mobile setup means we carry a full assortment of key blanks, pin kits, and cylinder tools on every service vehicle. When we arrive at your address, we verify your ownership or tenancy before touching anything — that verification step matters and we take it seriously. The work is performed on-site, typically without removing doors from hinges, and we aim for a completely damage-free process on every call. Once the rekey is complete, we test each new key in every lock we've serviced and hand you the working set before we leave.

The clearest trigger for a residential rekey is a change in who has held a key: moving into a new or previously rented property, ending a relationship with a roommate or partner, losing a key in a public place like the CTA, or completing a home renovation where contractors had access. Chicago renters and buyers sometimes underestimate how many key copies circulate over the life of a building — in dense neighborhoods like Andersonville, Rogers Park, or Edgewater, multi-unit buildings can go decades with the same lock cylinders and dozens of duplicate keys unaccounted for. A rekey closes that gap immediately.

On the other hand, if a lock is physically damaged — corroded, forced, or simply worn past smooth operation — a full lock replacement makes more sense than a rekey. Our technicians will tell you honestly which route fits your situation during the assessment, and we confirm an exact up-front price before any work begins. Factors that shape the final quote include the type of lock (a standard door knob lock versus a complex mortise lock assembly), the number of locks being rekeyed, time of day, travel distance to your location, and whether any parts such as new cylinders or keys need to be sourced.

Chicago's architectural history means a large share of homes in Andersonville and surrounding North Side neighborhoods still have original or period-correct mortise locks — the rectangular, pocket-set assemblies mortised directly into the door edge, often with ornate faceplates. These locks are durable and can last generations, but rekeying them requires a different skill set than working on modern cylindrical locks. Our technicians are experienced with mortise lock cylinder extraction, pin configuration, and reassembly across a wide range of manufacturers and configurations. We treat this as a core residential locksmith service, not a specialty add-on.

Beyond mortise locks, our home rekey service covers single-cylinder deadbolts, double-cylinder deadbolts, door knob lock sets, lever-handle locks, sliding patio door locks, keyed window locks, mailbox locks, garage side-door locks, padlocks, and master-key system rekeying for landlords managing multiple units. If you want every exterior lock on your property to operate from a single new key — a convenience called key consolidation — we can rekey the cylinders to match across compatible hardware. We also handle smart lock cylinder rekeying for hybrid models that retain a physical key backup alongside their electronic access. Whatever lock is on your door, call 773-900-5921 and we'll confirm we can service it before dispatching a technician.

Chicago doesn't slow down at night, and neither do the situations that make a rekey urgent. A late-night key loss on the way home from a shift, a weekend move-in where the building manager hands over keys that clearly aren't freshly cut, a broken-in door that the emergency locksmith just secured with a new lock — all of these call for same-day or same-night rekeying. Our team operates around the clock, every day of the year, and we answer live when you call 773-900-5921. There's no answering service, no next-morning callback window, and no after-hours surcharge surprise — pricing factors are explained and an exact price is confirmed before work starts, regardless of when you call.

Being a mobile residential locksmith means the entire service comes to you. We've rekeyed locks at courtyard apartment buildings off Bryn Mawr Avenue, coach houses tucked behind two-flats on Farwell, and vintage single-family homes along Catalpa. If your situation also touches on automotive locksmith needs — for example, a car key was lost along with your house keys — our technicians are equipped to handle vehicle lock work as well, since we carry automotive tools on every van. And for property owners who manage both a home and a business, our commercial locksmith capabilities extend the same rekeying and master-key services to office doors, storefront locks, and commercial-grade hardware. One call, one team, all covered.
