Rekey locks in San Marino usually costs between $95 and $210 for a standard job, and that’s the smart move when you’ve bought an estate, dismissed staff, or just want one key to work every door. This city’s homes lean old and ornate: 1910s through 1950s estates with solid-brass mortise locks, heavy wood doors, and hardware that doesn’t take kindly to off-the-shelf fixes. Greystone Locksmith has served San Marino since 2011, and we bring a working knowledge of Schlage, Kwikset, Medeco, and Yale hardware to every call. If you need rekeying, a car key, or an emergency unlock, call (866) 497-9415 for a straight answer first.
Why San Marino Homes Are Different
San Marino is a city of high-value, architecturally significant estates, many behind private gates and hedges with old-world hardware. A locksmith here is doing work that’s as much about preserving historic character and coordinating discreet access as it is about opening a door. The housing stock runs to Spanish Colonial, Tudor, and Mediterranean styles, with original solid-brass mortise locks, ornate entry plates, and heavy wood doors that have been swinging shut for a century. Many of these locks were built by manufacturers that no longer exist, which means replacement parts often need to be custom-milled or restored rather than pulled from a van shelf. Newer builds and remodels face a city design-review process that regulates visible exterior modifications, so swapping a lock or adding a keypad can involve matching the original ironwork or choosing hardware that reads period-correct.
The dry, warm climate and abundant mature landscaping create their own set of problems. Exterior locks and gate hardware collect dust from months without rain, and keyways clog. Sun bakes older finishes until they chalk or seize. The occasional heavy winter rain then swells wooden doors and jams locks that had been stiff for years. Seasonal lubrication, alignment checks, and keyway cleaning are routine calls for us here, and they’re cheaper than waiting for a lock to fail outright.
Styles & brands we work with
Our Main San Marino Services
Two jobs dominate our calls in San Marino: car key replacement, because losing a modern transponder key on an estate driveway is a different problem than losing one at a mall parking lot, and emergency lockouts, because gate hardware and century-old locks fail at inconvenient hours. Here’s what each involves.
Car Key Replacement in San Marino
Most San Marino drivers have at least one newer vehicle with a transponder or proximity key, and losing one means the car is stranded until a replacement is cut and programmed. We do that work in the field, at your home, without towing the car anywhere. San Marino’s long driveways and gated entries don’t slow us down; we carry the programming tools and key blanks in the van. If you’ve got a European, domestic, or Asian make that needs a key, read about Car Key Replacement in San Marino for the full picture.
Emergency Locksmith in San Marino
Estate gates, rear doors, and garage side doors are the usual emergency callouts here. Rare heavy rains swell those old wood doors, and a lock that was fine in October can refuse to turn in February. We respond ready for the lock in front of us, not just the brands we prefer. Our emergency coverage means a San Marino homeowner doesn’t wait until Monday. For the full detail on response and what to expect, see Emergency Locksmith in San Marino.

Rekey Locks in San Marino
Rekeying is often the smarter move, and we’ll tell you which is right for your situation. In San Marino, rekeying usually serves one of three moments: a household staff change, a purchase of a period estate with unknown key copies floating around, or a decision to consolidate three different keys into one. The 1910s through 1950s housing stock here means many locks are solid-brass mortise bodies that are worth keeping, not replacing. Rekeying preserves those original faceplates and escutcheons while killing every old key. Our full Rekey Locks page covers the process in depth.
Lock Rekey
Signs you need it
You’ve bought a home, dismissed a caregiver or housekeeper, or can’t account for every key that’s ever been distributed.
What it costs in San Marino
Standard lock rekeying here runs $95 to $115 per lock, including a small service call built into the total.
How we do it
We remove the cylinder, replace the pins to fit a new key, and reinstall it, leaving the lock’s original exterior finish untouched.
Rekey Door Lock
Signs you need it
Your front door key opens the back door but not a side entry, or a former resident or vendor still holds a key you’d rather not worry about.
What it costs in San Marino
Rekeying one door lock is typically $95 to $115, with additional cylinders on the same call lowering the per-lock cost.
How we do it
We match the new key to your existing hardware, and while the cylinder is out we clean and lubricate a lock that’s likely been stiff in San Marino dust.
Keyed Alike
Signs you need it
Your keyring has separate keys for front, back, garage, and side gate, and you’d rather carry one.
What it costs in San Marino
Keying multiple locks alike is generally $25 to $30 per cylinder beyond the standard $95 to $115 rekey fee, depending on how many locks we’re matching.
How we do it
We repin all selected cylinders so a single new key operates every lock in the set, and we test each one before we leave.
What Rekey Locks Costs in San Marino
| Item | Typical range in San Marino |
|---|---|
| Standard rekey (per lock) | $95 – $115 |
| Keyed alike (per additional cylinder) | $25 – $30 |
| Multiple locks, single visit | $115 – $210 |
Should I rekey or replace my old mortise locks?
Rekey when the lock body is sound and the hardware is original or high-quality. Replacement only makes sense when the lock is bent, corroded, or too worn to turn smoothly. On San Marino’s older brass mortise locks, rekeying preserves the original faceplates that a replacement would eliminate.
How long does a rekey job take in San Marino?
Most rekey jobs finish in 30 to 45 minutes when the locks are standard Schlage or Kwikset. High-security cylinders like Medeco take longer because each key cut is registered and the pinning is proprietary. Call (866) 497-9415 for an exact quote, and we’ll tell you the time window before we dispatch.
Brands We Service in San Marino
We work on the lock in front of us, not just the brands we prefer. For San Marino, that means daily familiarity with Schlage and Kwikset residential hardware, plus the high-security lines found on estate gates and wine rooms: Medeco, Mul-T-Lock, and Abloy. We keep common cylinders and finishing plates in the van, so most brand-specific work can start on the first visit. Full detail on every brand we service is on our brands page.

What San Marino Customers Say
"Told me over the phone that what I needed was a five dollar part from the hardware store, not a locksmith. I called him back a month later for real work because of that."
— Tamika Ingram"Rekeyed every lock in the house the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
— Yolanda Martinez"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Brooke Ackerman
