Rekey & Lock Change

Rekeying a lock means our technician disassembles the lock cylinder and replaces the internal pin tumblers so that every old key becomes useless while a brand-new key — cut on the spot from our mobile unit — operates the lock perfectly. The lock hardware itself stays in place. This is the right move when the hardware is in solid mechanical condition and you simply need to cut off access tied to a lost key or a previous occupant. It costs less in parts and takes less time, which is why it is the most common call we receive after a move-in day in Aberdeen.

A full lock change makes more sense when the existing hardware is worn, damaged, has been tampered with, or simply does not meet modern security standards. Upgrading from a basic builder-grade knob to a heavy-duty deadbolt, swapping an older mortise lock body for a current-grade unit, or installing a Schlage or Kwikset deadbolt where none existed before all fall under a lock change service. Our technicians carry a range of hardware grades on the van so we can complete most jobs in a single visit — no second trip required.

Mortise locks are the deep-set, rectangular lock bodies common in Aberdeen's older homes, historic commercial buildings on Union Avenue, and multi-unit properties throughout Harford County. Unlike a simple cylindrical knob or deadbolt, a mortise lock is recessed into a pocket cut into the door edge, and it integrates the latch, deadbolt, and sometimes an additional bolt into one unified mechanism. Rekeying or replacing a mortise lock incorrectly can misalign the strike plate, leave the door unable to latch, or crack an antique door edge that cannot easily be repaired — which is exactly why this work should never be a DIY experiment.

Our technicians are experienced with full mortise lock disassembly, cylinder replacement, and complete mortise lock body swaps. We carry mortise cylinders compatible with common body formats so we can rekey on-site without waiting on an order. If you are upgrading an older Aberdeen property to higher-grade hardware while preserving the door's original mortise pocket, we will measure the existing pocket, source a matching-footprint replacement, and install it with clean, damage-free technique. The result is a door that looks original from the outside while offering current security performance on the inside.

The calls we receive most often break into a handful of clear situations: a new homeowner who just settled on a property near Baker Road and wants a clean break from whoever held keys before closing; a tenant whose landlord handed over a key ring of unknown history; a resident along Bel Air Road who lost their key set and cannot be certain whether someone picked it up; a property manager turning over a rental unit in one of Aberdeen's older residential neighborhoods; and business owners along the US-40 commercial corridor who need a commercial lock change after an employee departure. Each situation carries its own urgency level, but all of them share the same underlying need — certainty about who can and cannot open the door.

We also handle less obvious scenarios: door knob lock replacements on interior doors for privacy or security room purposes, combination changes on Master Lock padlocks securing storage units or outbuildings, code resets on Defiant smart locks and Honeywell door locks after an access code has been shared too widely, and emergency locksmith calls when a damaged lock leaves a door unable to close at all. If you are in Harford County and the situation feels urgent, call (410) 267-3887 — we answer every hour of every day, including holidays.

We do not publish flat-rate tables because lock work is not one-size-fits-all. The factors that shape your final price include: the lock type and grade (a basic door knob lock rekey differs significantly from a heavy-duty commercial mortise lock change), the number of locks being serviced in a single visit, whether new hardware needs to be supplied from the van's stock, the time of day the call comes in, and the travel distance to your location within the Aberdeen and greater Harford County service area. A standard daytime rekey on a modern deadbolt is a shorter, simpler job than a late-night emergency locksmith call involving a damaged mortise lock on a commercial property.

What we guarantee regardless of circumstances: before any work begins, our technician will assess the job, explain exactly what needs to be done, and give you a confirmed price. You approve it before we pick up a tool. There is no invoice surprise at the end, no hidden fee for mileage within our service area, and no pressure to choose a higher hardware grade than your situation actually calls for. We will tell you honestly if a simple rekey solves your problem so you do not pay for a full lock change you do not need.

Because we are a fully mobile operation, our technicians carry the tools, blank key stock, and common hardware needed for most residential and commercial rekey and lock change jobs directly on the vehicle. When you call (410) 267-3887, we confirm your address, give you a realistic arrival window, and dispatch the closest available technician. For new customers or after-hours calls, we will ask you to verify ownership or tenancy before work begins — a government-issued ID, a lease agreement, a mortgage document, or a utility bill in your name at the address is typically sufficient. This is a standard and necessary step that protects you as much as it protects us.

On arrival, the technician inspects the existing hardware, discusses your options, confirms the price, and gets to work. Most residential rekeys on one to three locks are completed within 30 to 60 minutes. Mortise lock work or a multi-lock commercial job takes longer, and we will give you a realistic time estimate up front. When the job is done, we test every rekeyed or replaced lock multiple times with the new key before handing anything over. You will watch the test yourself so there is zero doubt the job is right before we leave your property.
