You just got the keys to your new Richmond home — maybe a craftsman bungalow near the Pt. Richmond waterfront, a bungalow off Macdonald Avenue, or a newer build closer to the BART station. Exciting as that is, one question deserves your attention before you unpack a single box: who else has a copy of those keys? The previous owner, their relatives, a former tenant, a contractor, a housesitter — the list is longer than most buyers realize. Rekeying or replacing your locks is the single most important security step you can take on day one, and knowing which option fits your situation saves you time and money.
This guide breaks down the real difference between rekeying and full lock replacement, explains when each makes sense, touches on how to change a door lock or a keypad code, and covers the specific lock types — including mortise locks — that are common in Richmond homes. By the end, you will know exactly what to ask a locksmith and what to expect from the process.
## Rekey vs. Replace: What Actually Changes Inside a Door Knob Lock or Deadbolt
Rekeying means a locksmith disassembles the lock cylinder — the part the key slides into — and replaces the small internal pins and springs inside it. The result is a lock that works with a brand-new key and renders every previous key useless, while the hardware on your door stays exactly the same. Full replacement means removing the entire lockset — knob, deadbolt, strike plate and all — and installing new hardware from scratch. Both methods accomplish the same security goal: cutting off access for anyone who held a previous key. The difference is scope, time, and the factors that affect the final quote.
Rekeying is almost always the right call when the existing hardware is in good mechanical condition, the grade of lock meets your needs, and you simply want to sever access from prior keyholders. Full replacement makes more sense when the lock is damaged, when you are upgrading from a basic builder-grade knob to a higher-security deadbolt, or when you are switching lock brands across multiple doors so that one key operates everything. For most Richmond homeowners moving in, rekeying deadbolts and door knob locks is the practical first step — it is faster, uses fewer parts, and the locksmith can often key multiple locks alike so you carry one key for the whole house.
## Mortise Lock, Deadbolt, or Keypad? Knowing Your Lock Type Changes Everything
Richmond's housing stock spans more than a century. Older homes near the historic districts often have mortise locks — a rectangular lock body that fits into a deep pocket (mortise) cut into the door edge, combining the latch and deadbolt function in a single unit. Mortise locks are robust and repairable, but they require a locksmith with specific experience because the cylinder replacement process differs from a standard cylindrical deadbolt. If your new home has antique mortise lock hardware, do not assume a general handyman can handle the job — the tolerances are tight and a misaligned cylinder can leave you locked out. Our team services mortise locks regularly and carries compatible cylinders for the most common profiles found in Richmond properties.
Modern Richmond homes and recent renovations frequently use Schlage or Kwikset cylindrical deadbolts, which are straightforward to rekey. An increasing number of properties also have keypad door locks — electronic locksets that accept a PIN instead of (or in addition to) a physical key. If you have moved into a home with an existing keypad lock, changing the code immediately is just as important as rekeying a physical cylinder. How to change the code on a door lock varies by brand and model, but the general process involves entering the current programming code, pressing a designated button, and entering your new PIN. The owner's manual for your specific model will have the exact sequence; if the previous owner did not leave the programming code, a qualified locksmith can factory-reset most keypad models. Call us at (510) 930-3035 any time — we answer 24/7 and can walk you through your options or dispatch a technician to your door.
## How to Change a Lock the Right Way — Steps, Tools, and When to Call a Pro
For homeowners who want to understand the process before a locksmith arrives — or who are considering a DIY deadbolt swap — here is how to change a door lock in plain terms. You will need a screwdriver (usually Phillips and flathead), the replacement lockset, and potentially a hole saw if the door prep does not match the new hardware. Remove the interior and exterior knobs or levers, unscrew the latch bolt from the door edge, and lift out the deadbolt or knob assembly. Install the new latch first, thread the exterior assembly through, attach the interior rose and thumb-turn, and test the throw before closing the door. Always test the lock with the door open so you do not accidentally lock yourself out during installation.
That said, there are several situations where professional help is the smarter call. If your door has a mortise lock, the cylinder removal requires a spanner wrench and knowledge of set-screw locations that vary by manufacturer. If you are rekeying multiple locks to a single key, you need a rekeying kit matched to the specific brand — Schlage pins are not interchangeable with Kwikset pins. And if you are dealing with a damaged lock, a misaligned strike plate, or a door that does not close squarely (common in older Richmond homes that have settled over the years), the underlying issue needs to be addressed alongside the lock work. A skilled locksmith will spot those problems immediately; a rushed DIY job can leave gaps in both security and weatherproofing.

## Trusted Help When You're Locked Out in Richmond, CA — and What to Expect From the Call
A lockout — whether from your new home, your car in a Richmond parking lot, or your business after hours — is stressful. Knowing what to expect when you call an emergency locksmith makes the situation easier to manage. When you reach us at (510) 930-3035, we will ask for your location, a description of the lock or vehicle, and confirmation that you are the owner or authorized occupant. That verification step is not bureaucratic friction — it is how responsible locksmiths operate. We confirm an exact, up-front price before any work begins, so there are no surprises on the invoice. The factors that determine your quote include the type of lock or vehicle, the service required, the time of day, travel distance to your location, and whether any parts — cylinders, keys, or electronic components — need to be replaced.
For homeowners who have just moved into Richmond and want to handle everything in one visit, we can rekey all exterior locks, cut new keys, assess any mortise lock hardware, reset keypad codes, and check that deadbolts and strike plates are properly aligned — all in sequence, on the same trip. If you want to upgrade to a smart lock or a higher-security mortise lock while we are there, we can discuss the options and add that work to the same appointment. Whether it is a routine rekey at noon or an emergency lockout at 2 a.m. on a Tuesday, San Pablo Locksmith is available. Call (510) 930-3035 — we answer 24/7 and can usually have a technician on the way within the hour.
Frequently asked questions
How much does a local locksmith charge for rekeying or replacing locks?+
There is no single flat answer because the final quote depends on several factors: the type and brand of lock (a standard Kwikset deadbolt differs from a vintage mortise lock), the number of locks being serviced, whether new keys need to be cut, the time of day, and travel distance to your location. What we can promise is that we confirm an exact, up-front price with you before any work begins — no surprise fees after the job is done. Call (510) 930-3035 for a straight answer based on your specific situation.
Can a locksmith make a new key from a lock — even if I have no existing key?+
Yes. A trained locksmith can decode a lock cylinder by disassembling it and reading the pin heights, then cut a new key to match — a process sometimes called impressioning or decoding. This is particularly useful for mortise locks on older Richmond homes where original keys were lost long ago, and for car locks where a key was never provided with the vehicle. The same visit can include rekeying the lock if you want to ensure no other copies of the decoded key are floating around.
What should I ask a locksmith before hiring them for a move-in rekey?+
Good questions to ask: Are you insured? (We are.) Will you give me a firm price before starting work? (We will.) Do you carry cylinders and pins for my lock brand on the truck? (We stock common Schlage, Kwikset, and mortise lock components.) Can you key multiple locks alike in a single visit so I only need one key? (Yes, as long as the locks are compatible brands.) And can you check whether my deadbolts and strike plates are properly installed — not just rekeyed? (Absolutely — proper strike plate depth is as important as the lock itself for real security.) These questions weed out technicians who are not prepared to do thorough work.
How do I change the code on a keypad door lock myself, and when should I call a locksmith instead?+
Most keypad door locks follow a similar process: enter the existing master or programming code, press a dedicated program button (often marked with a gear or key icon), then enter your new PIN twice to confirm. The exact button sequence varies by model, so your owner's manual is the authoritative source. You should call a locksmith when the previous owner's programming code is unknown (a factory reset requires specific steps that vary by brand and can lock out the unit if done incorrectly), when the keypad is unresponsive or showing error codes, or when you want to add a physical key cylinder alongside the electronic entry. We handle keypad resets and smart lock programming regularly — call (510) 930-3035 any time.
