Just Moved In? When to Rekey vs. Replace Your Locks

Rekeying a lock means changing the internal pin configuration inside the lock cylinder so that the old keys no longer work and only brand-new keys will operate the lock. The lock body, the door hardware, and the strike plate all stay exactly as they are — only the tiny pins inside the cylinder are replaced. This is a genuinely useful distinction: the security of your door depends on those pins matching your key, not on the age or brand of the hardware itself.

A skilled locksmith — working on everything from a standard door knob lock to a heavier-duty mortise lock — can rekey a lock cylinder quickly and without damaging your existing hardware. A mortise lock, which is common in older Newport News homes and some commercial properties along Warwick Boulevard, has a more complex body than a simple knob set, but the rekeying principle is the same: new pins, new key, total peace of mind. Once the work is done, you hand out fresh keys only to the people you choose, and every previous copy becomes useless.

When a professional arrives at your home, the process of rekeying a door lock begins with removing the lock cylinder from the door. For a basic knob or deadbolt, this usually means removing a retaining clip or a set screw. For a mortise lock — the rectangular case that sits inside a mortised pocket cut into the door edge — the cylinder is extracted from the face of the lock body. The locksmith then uses a specialized plug follower tool to push out the existing key pins and springs, replaces them with a new set of pins sized to match a fresh key blank, and reassembles everything. The door is tested several times before the technician considers the job done.

Here is the part that matters most to you as a homeowner: you do not need to know how to rekey a lock yourself. Attempting a DIY rekey without the right tools — particularly on a mortise lock or a high-security cylinder — risks damaging the plug or the driver pins, which can leave you with a lock that binds or fails altogether. A trained locksmith brings the right plug followers, pinning mats, and key gauges for your specific hardware, which means the job is done correctly the first time. If you have multiple doors, a locksmith can also rekey all your locks to match a single existing key, so one key works every entry point — a process sometimes called keying alike.

Rekeying is the right choice when your lock hardware is in solid mechanical condition — meaning the deadbolt throws smoothly, the knob turns without grinding, and the strike plate is solidly anchored. If those things are true, rekeying gives you full key control at a fraction of the cost and disruption of installing new hardware. It's especially practical when you've moved into an established neighborhood like Denbigh or Hidenwood, where homes often have quality older hardware that simply needs a fresh start with new keys.

A full lock replacement makes more sense in a handful of specific situations. If the lock mechanism is worn — you feel grinding, the bolt is slow to retract, or the lock has visible damage from a past break-in attempt — replacing it solves both the security and the mechanical problem at once. Upgrading to a higher-security deadbolt, a smart lock with keypad or app access, or a commercial-grade mortise lock is also a legitimate reason to replace rather than rekey. And if you have a door knob lock without a separate deadbolt, that's a good moment to add one rather than simply rekey what's there. Your locksmith can assess the condition of each lock on-site and give you an honest recommendation — not every lock needs to be replaced, and a trustworthy professional will tell you that plainly.

One of the most common questions new homeowners ask is how long does it take to rekey a lock. For a single standard deadbolt or knob set, an experienced locksmith typically completes the job in ten to twenty minutes per lock. A mortise lock takes a bit longer given its more involved cylinder removal, and if you're having several locks rekeyed to match a single key, expect the visit to run between thirty minutes and an hour for a whole house. An emergency locksmith call in the middle of the night will obviously have different timing considerations than a scheduled morning appointment.

When it comes to what you'll pay, several factors shape the final quote: the type of lock (a basic knob lock versus a full mortise lock), the number of locks being rekeyed, whether new hardware or parts are needed, the time of day or night, and travel distance to your property.

How do I choose a reputable locksmith? It's a fair question, especially when you're new to an area and don't yet have local recommendations. Look for a mobile locksmith who operates locally — not a national call center that dispatches whoever is available — and who will confirm pricing before work starts. Ask whether they carry insurance. Ask whether they have experience with your specific lock type, whether that's a standard Schlage or Kwikset deadbolt, a Medeco high-security cylinder, or a legacy mortise lock in an older Colonial-style home. A professional who hesitates to answer those questions clearly is one worth reconsidering.
