Rekey & Lost Key Service

When a key goes missing, the instinct for many people is simply to duplicate a spare and move on. That approach leaves a critical gap: whoever has your original key — whether a stranger who found it or someone who took it deliberately — still has access to your home or business. A proper lock rekey service eliminates that risk entirely without requiring you to purchase new hardware. During a rekey, a trained technician disassembles your lock cylinder and replaces the internal pin stack with a new configuration, rendering every previously cut key useless. Your existing deadbolt, knob set, or mortise lock body stays in place; only the secret code inside it changes. It is the most cost-effective, damage-free way to reclaim control of who can open your door.

This is especially important for Miami residents in densely populated neighborhoods like Little Havana, Overtown, or the Design District, where a dropped key on a busy sidewalk could be picked up by anyone. Our mobile technicians arrive in a marked vehicle, verify property ownership before beginning any work, and complete the rekey on-site — typically within the same visit that cuts your new keys. If you have just moved into a new rental or recently purchased a home anywhere in Miami-Dade County, a rekey service is one of the smartest first calls you can make. You simply do not know how many copies of the previous key are floating around.

Mortise locks are a different beast compared to the cylindrical knob sets and deadbolts found on most newer construction. These locks are recessed into a pocket — or mortise — cut directly into the door edge, with a large rectangular case housing the latch, deadbolt, and sometimes a chain mechanism all in one unit. They are common on Miami's older Mediterranean Revival and Art Deco properties in Coconut Grove and Coral Gables, as well as on commercial storefronts throughout Downtown Miami and the historic buildings along Flagler Street. When you face a mortise lock lost key situation, the replacement process requires specialized key blanks and a technician who understands the particular cylinder profile — typically a rim or mortise cylinder — fitted to your specific lock body.

Our technicians are experienced with the full range of mortise lock configurations, including single-cylinder, double-cylinder, and lever-handle variants from major manufacturers. A mortise lock lost key call is not a job for a hardware store key kiosk — the blanks are often proprietary and the cutting tolerances are tighter. We carry a broad inventory of mortise cylinder key blanks in our mobile units and can cut and program replacements on the spot. If the cylinder itself has been compromised — jiggled, forced, or simply worn from years of Miami humidity — we can rekey or replace just the cylinder without disturbing the rest of the mortise body, keeping your existing door hardware intact and functioning.

The first question most callers ask is some variation of: how much does a locksmith cost in Miami, how much does a local locksmith charge, or what does an emergency locksmith cost? These are fair questions, and we answer them honestly. The final price for any rekey or lost key service depends on several specific factors: the type and brand of lock involved (a basic door knob lock rekey is a different scope of work than rekeying a multi-point mortise lock system), the number of locks being serviced in the same visit, the time of day (after-hours and overnight calls involve additional technician dispatch costs), your location within Miami-Dade and the associated travel distance, and whether parts — new pins, replacement cylinders, or specialty key blanks — are required. We walk through every one of these factors with you on the phone and confirm an exact price before our technician begins work. No surprise charges appear on your bill when the job is done.

To reach us any time — day or night, weekday or weekend — call 305-290-6142. Our dispatch team answers 24/7 and can typically give you a firm arrival window within minutes. Once our technician arrives, they will verify your identity and ownership of the property before proceeding, a standard step that protects both you and the integrity of our service. Whether you are calling at 2 p.m. from a Doral office park or at 2 a.m. from a Brickell apartment lobby, the process is the same: professional verification, an up-front confirmed quote, then skilled, damage-free work. If you need both a rekey and new keys cut in the same visit, we coordinate both tasks together so you leave the job with a fully secured property and working keys in hand.
