Rekey or Replace? What to Do With Your Locks After Moving in San Marino

Rekeying means a skilled locksmith removes the cylinder inside your existing lock and rearranges the tiny pin stacks inside it so that only a brand-new key will operate it. Your old keys — and every copy ever made — stop working instantly. The lock hardware itself stays exactly where it is. This works for standard deadbolts, door knob locks, and even high-security mortise lock cylinders, provided the hardware is in good working condition and is a style your locksmith can service. Rekeying is the go-to move when the lock is relatively new, functions smoothly, and you simply need to revoke access from unknown keyholders.

Full lock replacement means the entire lockset — cylinder, housing, bolt mechanism, and all — is removed and a new unit is installed. This is the right call when the existing hardware is worn, damaged, outdated, or simply not up to the security standard you want. It's also the appropriate choice when you're upgrading from a basic door knob lock to a heavy-duty mortise lock, or when you're adding a deadbolt where none existed before. A mortise lock, for context, is a recessed unit that fits into a pocket cut into the door edge rather than sitting on the surface — it's significantly more robust than a standard cylindrical lockset and is often the preferred upgrade for exterior doors on homes that want a meaningful step up in security.

If your home's locks are in solid mechanical shape — the deadbolt throws cleanly, the door knob lock turns without grinding, and the strike plate is properly aligned — rekeying is almost always the more practical first step. It accomplishes the single most important security goal: making every previously issued key useless. For a home like those along Virginia Road or near Lacy Park, where original craftsman-era hardware may still be in place and functioning well, rekeying lets you preserve quality vintage hardware while immediately securing your household against unknown keyholders.

There's another scenario worth knowing: if you've recently dealt with a situation where you were locked out of your house — maybe a contractor had a spare and you're not sure whether they returned it — rekeying addresses that concern completely. What to do if locked out of your house in the future is a separate question (check for open windows you can safely access, call a trusted neighbor who holds a spare, or contact an emergency locksmith), but rekeying right now prevents that lockout from turning into an unauthorized entry by someone else. A trained locksmith can typically rekey multiple locks in a single visit and hand you a matching set of fresh keys on the spot.

Replacement becomes the clear answer in several situations: the existing lock is visibly damaged or shows signs of attempted forced entry; the hardware is decades old and no longer holds up reliably; or you want to upgrade the security profile of the door entirely. This is especially relevant for homes with older cylindrical locksets that were never upgraded — swapping to a quality mortise lock on a primary entry door is one of the most effective physical security improvements you can make. A mortise lock's internal mechanism is more complex and tamper-resistant than surface-mounted options, and a skilled locksmith will route the mortise pocket, fit the faceplate flush, and ensure the strike box in the frame is properly reinforced.

Replacement also makes sense if you're standardizing hardware across multiple doors and want them keyed alike — something a commercial locksmith handles routinely for business properties but that residential clients appreciate too, especially in a larger home where juggling five different keys becomes genuinely frustrating. If you're moving into a property with a mix of lock types and ages, an experienced locksmith can assess each door, identify which units are worth rekeying and which should be swapped, and give you a clear, up-front price before any work begins. Factors that shape that quote include the type and brand of lock (Schlage, Kwikset, or a higher-security line), the number of doors, the time of the service call, and any parts required for a replacement.

Locksmithing is a genuine trade with distinct specialisations — residential, automotive, commercial locksmith work, safe and vault services, and emergency response. In the United States, licensing requirements vary significantly by state. California requires locksmiths to carry a valid Bureau of Security and Investigative Services (BSIS) license — you can verify any locksmith's BSIS registration on the California Department of Consumer Affairs website. In the United Kingdom, the trade is largely self-regulated, with professional bodies like the Master Locksmiths Association setting voluntary standards, though there is no single national licensing law as of this writing. Knowing this distinction matters if you're originally from the UK or another country and are used to different baseline expectations. In California, always ask to see a state license number before work begins.

A question we hear often is: 'How do I know if a locksmith is legit?' The practical checklist is straightforward. Confirm they have a verifiable California BSIS license. They should arrive in an identifiable vehicle, present ID, and be willing to provide an exact written or verbal price before touching anything. A professional will also ask you to verify ownership or occupancy — a driver's license matching the address, a lease agreement, or a closing document. If a locksmith shows up, quotes a suspiciously vague price range, and gets to work without asking any of these things, treat that as a red flag. At Huntington Dr Locksmith, every call starts with ownership verification and a confirmed up-front price — no surprises on the invoice. If you ever find yourself locked out and wondering what to do when locked out of your house, those same steps apply: a legitimate emergency locksmith will verify who you are before they do anything else. Call us any time at (626) 412-3726 — we answer 24/7 and can be on the road to you quickly.

Once you've closed on your San Marino home, here's a clean action plan. First, count every lock on every exterior door, including side gates and garage entry points if they use keyed locks. Note the brand and condition of each. Second, call a trained locksmith — ideally before or immediately after your first night — and request an assessment. A good locksmith will walk each door with you, test the hardware, and recommend rekey or replace on a door-by-door basis rather than applying a one-size-fits-all answer. Third, ask about mortise lock options for your primary entry if you're working with a basic knob-and-deadbolt setup — the upgrade conversation is worth having at least once so you can make an informed decision.

On the topic of cost: there's no single flat number that applies to every situation, and any source that quotes one without knowing your specific locks is guessing. What an emergency locksmith costs near you depends on the type of service (rekey versus replacement, standard versus mortise lock), the lock hardware involved, the time of day, and travel distance to your address. Our process is simple — we confirm the exact price before we start, with no hidden fees added at the end. One final note on tips: tipping a locksmith is never required or expected, but it's a appreciated gesture for after-hours or particularly involved jobs. If you're also wondering whether a locksmith can program a key fob for your vehicle (yes, in many cases a skilled automotive locksmith can handle transponder key and fob programming on-site), that's a separate service we offer as well — useful to know if you're juggling both a new home and a new set of car keys after a move.
