Should You Rekey or Replace Your Locks After Moving to Memphis?

Rekeying and replacing a lock are two completely different operations, even though they achieve the same end goal — making old keys useless. When a skilled locksmith rekeys a lock, they disassemble the lock cylinder and swap out the small metal pins inside (called key pins or driver pins) to match a new key cut. The existing hardware — the deadbolt, the latch, the strike plate, the entire lock body — stays exactly where it is. Only the internal pin configuration changes, so your old key no longer turns the cylinder. It's precise, mechanical work that requires professional training to do correctly without damaging the cylinder.

Full lock replacement means removing the entire lock assembly and installing a brand-new unit. The door prep (the bored holes in the door) stays the same, but every component you see and touch is new. Replacement makes sense when the existing hardware is worn, damaged, outdated, or simply not up to the security standard you want. Many Memphis homeowners moving into older properties along corridors like Summer Avenue or into craftsman bungalows in Cooper-Young discover older mortise lock systems — a style of lock that sits in a deep rectangular pocket cut into the door edge rather than a cylindrical bore. Mortise locks are extremely robust and worth preserving when they're in good shape; an experienced locksmith can rekey a mortise lock cylinder just as readily as a standard deadbolt, keeping that quality hardware working for another decade.

The professional process for rekeying a door lock follows a precise sequence. A trained locksmith removes the lock cylinder from the door using the appropriate tools, uses a key decoder to read the current pin configuration, removes the existing key pins, and installs new pins that correspond to a freshly cut key. The cylinder is then reassembled, tested, and reinstalled. The whole process on a standard deadbolt or door knob lock typically takes just a few minutes per cylinder once the locksmith is on-site — and the result is a lock that is just as secure as it was before, with zero keys from the previous owner working.

Can you rekey any lock? The honest answer is: most residential locks, yes — but not all. Standard Kwikset and Schlage deadbolts, knob locks, lever locks, and most mortise lock cylinders are all designed to be rekeyable. However, certain low-cost builder-grade locks use non-standard pin chambers that make rekeying impractical, and some novelty or very old lock designs simply don't have replacement pin kits available. A professional locksmith can assess your specific hardware in seconds and tell you whether rekeying is viable before any work begins. One particularly useful capability worth knowing: you can rekey a lock to match an existing key, so that multiple locks on your home all operate on a single key — a service called master keying or key consolidation that saves enormous daily inconvenience.

Not every lock on your front door is the same, and the rekeying approach varies by type. Mortise locks, common in older Memphis homes and in commercial properties, have a multi-function lock body recessed into the door. They typically contain a separate cylinder that a commercial locksmith or residential locksmith can extract and rekey independently. Because mortise lock hardware is often high quality and expensive to replace outright, rekeying is almost always the preferred first step unless the lock body itself is failing. If you're moving into a property — residential or commercial — with mortise lock hardware, have a professional inspect the cylinder condition before deciding to replace the whole assembly.

Smart locks add a layer of complexity to the rekeying conversation. Can you rekey a smart lock? It depends entirely on the specific model. Some smart locks include a traditional keyed cylinder as a backup, and that cylinder can be rekeyed just like any standard lock. Others are keypad- or app-only with no physical key cylinder at all — in that case, 'rekeying' means resetting the access codes and removing old user credentials, which is just as important. Can you rekey a smart lock without the original key? For models with a physical cylinder, a trained locksmith can often rekey without the original key, though it may require additional steps to disassemble the cylinder. Can you rekey a Yale smart lock specifically? Yale's residential smart lock line generally includes a rekeyable cylinder, so yes — though confirming the exact model matters.

Door knob locks — the round, spring-latch style common on interior and secondary exterior doors — are among the easiest locks to rekey and among the most overlooked. Many Memphis homeowners rekey the front deadbolt and forget entirely about the knob lock directly below it, which may accept the same old key. Rekeying both simultaneously, and setting them to match a single new key, is the smart and complete solution.

There are specific scenarios where rekeying simply isn't enough, and a full lock replacement is the correct answer. First: visible damage. If a lock shows signs of forced entry — a bent deadbolt, scarred strike plate, or a cylinder that spins without catching — rekeying doesn't fix the structural compromise. Second: outdated security grade. Many homes in Memphis's older neighborhoods were built with Grade 3 builder locks that offer minimal protection. Upgrading to a Grade 1 or Grade 2 deadbolt with a reinforced strike plate and 3-inch screws is a meaningful security improvement that rekeying alone can't provide. Third: worn internal components. A lock cylinder that's been used for 20 years may have worn springs and driver pins that cause intermittent failures — rekeying a worn-out cylinder just gives you a new key for an unreliable lock.

Fourth, and less obvious: the previous owner made unauthorized modifications. Homeowners sometimes install non-standard pins, add a secondary lock cylinder, or use a lock that was previously picked or bumped and never properly serviced. An experienced locksmith can spot these situations quickly. When our team arrives at a property, we assess the condition of every lock on the exterior — front door deadbolt, door knob lock, side-entry, garage entry, and any mortise lock on French doors or older entry systems — and give you a straight, honest recommendation for each one before any work starts. The factors that determine your final quote include the lock type and hardware brand, how many cylinders need service, your location within the Memphis metro area, and whether any parts need to be sourced. We confirm an exact up-front price before we begin, so there are no surprises.

Before you call a locksmith, a quick walk-through of your property answers most of the questions for you. Start at the front door: is the deadbolt a name-brand lock in good physical condition with no visible damage? Rekeying is likely sufficient. Is the lock a generic builder-grade unit, more than 15 years old, or showing wear? Replacement makes more sense. Check the door knob lock directly below it — if it's keyed, it needs attention too. Move to every keyed exterior entry point: garage entry door, back door, any French doors with mortise lock hardware, and any secondary deadbolts. Note the condition and brand of each.

If the home has a security system, coordinate the lock decision with the system reset — you want both completed before you sleep in the house the first night. If the property includes a detached garage, workshop, or rental unit, those locks need the same scrutiny. For homeowners taking over a commercial space or mixed-use property in Memphis, a commercial locksmith assessment of the full master key system is worth scheduling as a separate appointment. Moving day is chaotic enough — if you can schedule your locksmith appointment for the morning of or the evening before move-in, you'll have peace of mind from the first night. Our team is available around the clock across the Memphis area, so the timing works around your schedule, not the other way around. Call 901-676-8875 any time — we answer 24/7 and we'll confirm your exact service options and price before anyone picks up a tool.
