There are moments when you do not need new locks — you need new keys. Moving into a property where you cannot account for every copy. A tenant who has moved out. A relationship that has ended. Keys that were lost somewhere they should not have been. The locks are functioning correctly. What has changed is your confidence in who holds a working key. Rekeying is the answer.
Mission Locksmith rekeyes residential locks across all of Ridgely, MD in a single mobile visit, cutting new keys on-site and permanently disabling every previous key — without touching your door hardware. It costs significantly less than replacing locks, takes ten to fifteen minutes per cylinder, and leaves your home fully secured with keys in only the hands you choose.
Every standard residential lock uses a pin tumbler mechanism. The cylinder contains shafts, each holding a key pin and a driver pin separated by a spring. The correct key pushes each key pin to a precise height, aligning every gap at the shear line simultaneously so the cylinder can rotate. Rekeying replaces the key pins with a new set of different heights matched to a new key. The old key's cut profile no longer matches. It cannot align the pins. It will never open that lock again.
The deadbolt body, the knob or lever handle, the strike plate, the door frame reinforcement, the escutcheon plates, and all visible door hardware remain completely undisturbed. The only thing that changes is the small set of key pins inside the cylinder. This is why rekeying costs significantly less than lock replacement: no new hardware to purchase, no installation into the door, no finishing or adjustment work.
The most important rekeying moment. Previous owners, estate agents, contractors, cleaners, and inspectors all held copies. You have no way of knowing how many exist. Rekeying every exterior lock immediately after taking possession costs a fraction of replacing the hardware and takes one to two hours. When done, you are the only person with a working key.
A lost key that cannot be accounted for is a security vulnerability until the lock is rekeyed. If lost in a public place where it could be connected to the property through a tag, address label, or accompanying items, the risk is real and immediate. Rekeying eliminates it completely.
They return the keys they were given. They do not return copies they may have had cut. There is no reliable way to confirm all copies were returned. Mission Locksmith treats tenant turnover rekeying as one of the most routine and important services we provide in Ridgely, MD.
When someone trusted with access is no longer trusted, the correct response is to rekey. Even if the key was returned, copies may exist. Rekeying closes the question entirely. Mission Locksmith handles these calls with discretion and can usually attend the same day.
Tradespeople, cleaners, dog walkers, pet sitters — any service provider given temporary key access represents a loose end once that relationship ends. Rekeying once the need for access has ended is the clean solution.
If entry was achieved through a copied key, a bypassed lock, or an unexplained means, rekeying is part of the security restoration. If forced entry damaged the hardware, replacement may be needed instead — Mission Locksmith technicians assess and advise honestly.
Many homes have front doors, back doors, side gates, and garage entry doors each on a different key. If the locks share a compatible keyway, Mission Locksmith can rekey all of them to operate on a single identical key in a single visit. One key instead of four.
Security professionals recommend rekeying residential locks every five to seven years. Pin stacks accumulate wear that can make the lock marginally easier to manipulate. Rekeying replaces the worn pins and gives the technician an opportunity to assess overall cylinder condition.
If your locks work smoothly, no visible rust or damage, and the door and frame are properly aligned — rekeying is almost always right when the goal is to invalidate existing keys. The security outcome is identical to replacing: no previous key works, new keys are controlled by you. Pick resistance, physical strength, and security grade are unchanged.
A stiff or failing cylinder needs replacing. Visibly corroded, cracked, or damaged hardware needs replacing. Very old or builder-grade locks worth upgrading should be replaced. Moving to a smart lock or keypad means replacement. Rekeying cannot fix mechanical wear or bridge different technologies.
Rekeying 3–4 exterior locks typically costs $100 to $200 all-in. Replacing the same locks with equivalent hardware typically costs $250 to $500 or more. For a homeowner whose locks are in sound condition, paying $100 to $200 instead of $300 to $500 for an identical security outcome is the obvious decision.
Multiple locks rekeyed to operate on a single identical key. Every lock opens with the same key, and only that key. The technical requirement is that locks must share a compatible keyway — same brand generally means same keyway. Kwikset with Kwikset, Schlage with Schlage. Mixed brands may need a cylinder swap. Mission Locksmith confirms compatibility on arrival.
Individual keys open specific locks while a single master key opens all of them. Landlords give each tenant a key for their unit while retaining a master for all units. Setting up requires engineering pin stacks so two different keys can each align the pins independently. More complex than standard rekeying — Mission Locksmith designs and installs these for residential and small commercial properties across Ridgely, MD.
Locks sharing a compatible keyway. Kwikset with Kwikset, Schlage with Schlage. Kwikset and Schlage use different keyways and cannot be keyed alike without replacing one set of cylinders. Mission Locksmith assesses compatibility at the start of every keyed alike job.
The vast majority of residential deadbolts and knob locks in Ridgely, MD. Includes most locks from Kwikset, Schlage, Yale, Weiser, Baldwin, and comparable brands. If your lock takes a standard residential key and is in reasonable working condition, it can almost certainly be rekeyed.
Wafer locks use flat metal wafers instead of pin stacks and cannot be rekeyed using standard techniques — they are usually replaced at low cost. High-security locks (Medeco, Mul-T-Lock, ASSA Abloy) can generally be rekeyed but require brand-specific tools and pinning components.
Some smart locks have a physical key cylinder that can be rekeyed like any standard pin tumbler. Others use proprietary digital key systems with no physical pins — access control is managed digitally by deleting old codes. Kwikset SmartKey locks use a proprietary self-rekeying mechanism. Mission Locksmith confirms options for your specific model.
The technician examines each lock — confirming brand, keyway, and cylinder condition. If any cylinder shows wear or damage making rekeying inadvisable, the technician says so and explains options before proceeding. Takes a few minutes per lock.
Using the existing key and professional follower tools, the technician removes the cylinder plug without dismounting hardware from the door. Existing key pins are emptied. New pins matched to the new key are seated. The plug is reinstalled and the old key is tested to confirm it no longer operates.
Once all cylinders are rekeyed, the technician cuts the required number of new keys on-site. Standard residential keys for all major brands are stocked on the vehicle.
New key tested in each lock from both sides. Old key tested to confirm non-operation. If any lock does not pass, it is opened and inspected before the technician leaves.

Yes, when the existing hardware is in good condition. Rekeying replaces only the key pins — the components that determine which key operates the lock. The physical strength of the deadbolt, the pick resistance of the cylinder, and the security grade are unchanged. A rekeyed lock in good condition provides identical security to a brand-new lock of the same model.
A single standard residential lock takes ten to fifteen minutes. A full home of four to six exterior locks is completed in one to two hours in a single visit, including new key cutting. No dismounting of hardware, no plastering, no finishing work. Mission Locksmith technicians arrive with all pin kits and key stock needed.
Yes, though it costs slightly more. The technician picks the lock open before rekeying it — typically under ten minutes for a standard residential pin tumbler. This adds $50 to $100 per lock. If calling Mission Locksmith for rekeying without the original key, mention this when booking for an accurate estimate.
Rekeying is almost always right when moving in, provided the hardware is in reasonable condition. The goal is to invalidate all previous keys — rekeying achieves that completely at a fraction of replacement cost. You keep the existing hardware, get new keys, and no previous key will ever work again. Replace only if locks are worn, damaged, or builder-grade worth upgrading.
Yes, if the locks share a compatible keyway. Same brand generally means same keyway. Kwikset with Kwikset, Schlage with Schlage. Kwikset and Schlage use different keyways and cannot be keyed alike without replacing one set of cylinders. Mission Locksmith assesses compatibility on arrival and advises on the options.
Most standard residential deadbolts and knob locks with a pin tumbler cylinder can be rekeyed. If your lock takes a standard residential key and is in working condition, it almost certainly can. Wafer locks — common on cabinets, filing cabinets, and some older knobs — cannot be rekeyed and are usually replaced. Some smart locks have a rekeyable physical cylinder; others do not. Describe your lock to the dispatcher and we will confirm.
It depends on how the break-in occurred. Forced entry with damaged hardware may need replacement first. Entry through a copied key, a bypassed lock, or unexplained means — rekey every exterior cylinder. Mission Locksmith technicians assess each lock individually and advise on whether rekeying or replacement is appropriate.
Standard rekeying produces one key that operates a specific lock. A master key system is an engineered arrangement where two different keys both operate the same lock: an individual change key for that specific lock and a master key that opens all locks in the system. More complex pin engineering — designed and installed by Mission Locksmith as a purpose-built access control arrangement.
Yes. They return the keys they were given but not copies that may have been made. There is no way to confirm all copies are accounted for.
