Should You Rekey or Replace Locks After Moving to Santa Monica?

Rekeying a lock means a trained locksmith disassembles the lock cylinder and replaces the internal pins so that the old key no longer works and a new key operates the lock perfectly. The hardware — the deadbolt, the strike plate, the door knob lock — all stays exactly where it is. Rekeying is the right call when your existing locks are in solid mechanical condition, less than five to seven years old, and a recognized brand like Schlage or Kwikset. It's also the answer to the common question: can you rekey a lock to match an existing key? Yes — a skilled locksmith can pin multiple locks on your new home to all operate on one key, which is enormously convenient when you have a front door, back door, and side gate to manage.

A full lock replacement makes more sense when the hardware is visibly worn, the deadbolt is a low-grade builder-grade unit with a short throw bolt, or you're upgrading to a mortise lock for significantly better security. A mortise lock is recessed into a pocket cut into the door itself, giving it far greater strength and resistance to kick-ins compared to the surface-mounted cylindrical locks most new construction uses. If your Santa Monica home has original doors — especially in older Spanish-style or mid-century properties common throughout the city — there's a real chance a mortise lock is already in place, and keeping that high-quality hardware while simply rekeying the cylinder is usually the smartest move. When the existing mortise lock is damaged or the mechanism is sluggish, full replacement ensures you're not trusting an aging mechanism to protect your home.

Homeowners often ask how do you rekey a lock, picturing a complex hour-long job. In practice, for a standard deadbolt or door knob lock, a professional can complete a rekey in roughly 15 to 30 minutes per lock. The process involves removing the cylinder from the lock body, extracting the existing driver pins and key pins using a plug follower tool, replacing the key pins with a new set sized to match the cuts of your new key, reassembling the cylinder, and confirming smooth operation. Every step is done right at your door — no lock is taken off-site.

The more important question is: can you rekey any lock? The honest answer is almost any lock can be rekeyed, with a few exceptions. Most Schlage, Kwikset, Baldwin, and similar brand cylinders are straightforward. High-security cylinders with patented keyways — the kind that come with restricted key duplication — can still be rekeyed by a qualified locksmith who works with that manufacturer's system. Mortise lock cylinders, which are common in older Santa Monica homes and in commercial locksmith work throughout the city, are equally rekeyable as long as the cylinder is in serviceable condition. The main exceptions are locks that are severely corroded, have stripped set screws, or use proprietary mechanisms that require factory servicing.

Smart locks add a layer of complexity to the move-in security question that purely mechanical locks don't. If your new home already has a smart lock installed, the previous owner's app may still have administrative access — and that's a real vulnerability. So can you rekey a smart lock? It depends on the brand and model. Many smart locks with a physical key cylinder — including a number of Yale smart lock models — do have rekeyable cylinders, and a skilled locksmith can address the physical key side of the equation. However, the digital side (PIN codes, app access, Bluetooth or Z-Wave pairing) must be independently factory reset, which is typically done through the lock's own reset procedure outlined by the manufacturer.

A question that comes up often: can you rekey a smart lock without the original key? For models with a physical cylinder, a trained locksmith can often rekey the cylinder without the original key present, using the same professional tools and techniques used for a standard lock. The digital credentials are reset separately and don't depend on physical key possession. If you're uncertain whether the smart lock in your new home has been properly reset, the safest approach is to call a professional who can assess both the physical cylinder and walk you through the manufacturer's digital reset process. For a genuinely connected home in Santa Monica, combining a properly reset smart lock with rekeyed or replaced conventional deadbolts on secondary doors gives you the most comprehensive coverage. If you'd like help assessing what you're working with before move-in day, call (310) 356-9461 — we answer 24/7 and can advise over the phone before you even schedule a visit.

Pricing for locksmith services depends on several concrete factors, and any trustworthy locksmith will confirm an exact up-front price before beginning any work. The variables that shape the final cost include the type of lock — a standard door knob lock or deadbolt costs less to rekey than a complex mortise lock with a multi-point mechanism; the number of locks you need serviced; whether parts (new cylinders, strike plates, lock sets) are required; the time of day, since emergency locksmith calls outside normal business hours carry a service premium; and travel distance within the Santa Monica area. A straightforward rekey of two or three standard locks on a move-in afternoon will look different on a quote than an emergency locksmith visit at 2 a.m. to replace a damaged mortise lock on a commercial property. The important thing is that you should never feel surprised by the final number — a professional will tell you exactly what the job costs before a single screw is turned.

As for how much should a locksmith charge to change a lock — the answer is genuinely: it depends on the lock. Swapping a basic interior door knob lock is a quicker job with fewer parts than replacing a heavy-duty mortise lock that requires precise fitting to an older door frame. What does the average locksmith charge per hour? Some locksmiths bill hourly; others quote flat rates per job or per lock. We quote per job so you know the complete cost upfront, without wondering how long the clock is running. For a commercial locksmith job — a multi-unit property manager rekeying an entire building's locks, for instance, or upgrading access hardware on a retail space near the Santa Monica Pier — volume and hardware complexity both factor into the quote, and we're happy to assess in person before committing you to anything.

Here's a practical sequence to follow the day you get the keys. First, do a full walk-through and count every exterior entry point: front door, back door, any side gates with keyed locks, garage entry doors, and any sliding doors with supplemental keyed locks. Second, test every lock with the keys you received — any lock that sticks, turns stiffly, or shows visible wear is a candidate for immediate replacement rather than rekeying. Third, note whether any locks are mortise locks (recessed into the door edge with a large rectangular faceplate) versus cylindrical locks (the more common round-faced deadbolt), since this affects how a locksmith will approach the job. Fourth, check whether any smart locks are present and whether the previous owner has provided reset instructions.

Once you have that picture, call a mobile locksmith who serves Santa Monica and ask for a same-day move-in security assessment. A skilled locksmith will inspect every lock, give you an honest recommendation on what can be rekeyed versus what should be replaced, and complete the work in a single visit so you can sleep in your new home with genuine confidence. If you find yourself locked out during the chaos of move-in day — it happens more than people expect — that's an emergency locksmith situation, and the answer to where can I find an emergency locksmith in Santa Monica is simple: call (310) 356-9461 and we'll dispatch a mobile technician to you immediately, any hour of the day or night.
