Rekeying locks in San Marino means working on homes built before 1940, with original mortise locksets and solid-brass hardware you won’t find at a hardware store. True Blue Locksmith has served San Marino since 2017, and we stock the parts and key blanks that century-old locks require. Most rekey jobs in the estate blocks off Huntington Drive and Euston Road involve hand-cutting keys for hardware that’s been out of production for decades, not swapping in modern cylinders. Call (877) 358-5506 for an honest quote before anyone is dispatched.
Why San Marino Homes Are Different
San Marino isn’t a tract-home city. The housing stock skews heavily toward 1910s through 1930s Spanish Colonial, Mediterranean, and Period Revival estates, many of which are locally landmarked or historically designated. That changes everything about locksmith work here. When we arrive at a 1928 Spanish Colonial on a deep lot off Huntington Drive, we’re usually looking at an original mortise lock body with a brass faceplate, ornate knobs, and a keyway that no modern blank matches. The job is preservation as much as repair.
The climate adds another layer. San Marino’s hot, dry summers and Santa Ana wind events push fine dust into gate mechanisms and lock cylinders. We regularly open locks in San Marino where the pins are fouled with grit, not broken. Seismic activity in the region also plays a role. Older homes with unreinforced masonry walls shift slightly over time, and even a quarter-inch of frame rack can cause a mortise lock’s deadbolt to bind against the strike plate. We don’t just rekey those locks; we realign the strike, file the faceplate, and make sure the bolt throws clean before we leave the driveway.
Then there’s the cultural-heritage review process. Any lock or hardware change visible from the street can trigger review by the city, which means homeowners in San Marino need a locksmith who understands when to repair versus when to replace, and who can source period-appropriate hardware rather than slapping in a modern deadbolt that would look wrong on a 1920s mahogany door.
Styles & brands we work with
Our Main San Marino Services
Most calls we take from San Marino fall into two categories: people locked out right now, and drivers who need a car key made without a tow to the dealer. Here’s what each involves here.
Car Key Replacement in San Marino
San Marino drivers tend to own vehicles that use transponder keys or push-to-start fobs, and losing the last working key on a long driveway off Euston Road is a lousy way to start the day. We cut and program replacement keys on site, including transponder and fob-style keys, without sending you to a dealership. If you’ve got one key left, we recommend getting a spare made before you need it. Full details on vehicles and key types: Car Key Replacement in San Marino.
Emergency Locksmith in San Marino
Lockouts here happen at iron gates, detached garages, and heavy front doors that close behind you. Our emergency service runs around the clock because a lockout doesn’t keep business hours. We carry the tools to open locks without destroying hardware, which matters a lot on a 1930s estate door where replacing the lock means a heritage review. See what to do if you’re locked out: Emergency Locksmith in San Marino.

Rekey Locks in San Marino
Rekeying in San Marino is often about key control on historically designated estates. When a house has passed through multiple owners, contractors, and caretakers over a century, nobody knows how many keys are floating around. The climate doesn’t help either: dust from Santa Ana winds and the occasional frame shift from seismic activity mean those old mortise locks need a locksmith who can rekey without destroying the original hardware. That’s the work we do most often here, and it’s why we stock key blanks and pins for locks most shops won’t touch. For a deeper look at the service, see Rekey Locks.
Lock Rekey
Signs you need it
You’ve bought a San Marino home with original brass mortise locks and have no idea who still holds keys to them.
What it costs in San Marino
Lock rekey service in San Marino typically runs $65 to $180 per lock, depending on whether it’s a standard cylinder or a century-old mortise body with hardened steel pins.
How we do it
We remove the lock cylinder, replace the internal pins to match a new key, reassemble the hardware, and test every key against the original door and jamb alignment.
Rekey Door Lock
Signs you need it
A door lock sticks or binds after years of San Marino dust and seismic settling, or you want one key to operate multiple original wood doors on the same estate.
What it costs in San Marino
Rekeying a door lock in San Marino typically falls between $65 and $180 for residential hardware, with high-security or commercial-grade cylinders priced higher.
How we do it
We disassemble the existing lock, inspect the cylinder and faceplate for wear, pin the cylinder to a new key, and adjust the strike plate so the deadbolt throws cleanly.
What Rekey Locks Costs in San Marino
| Item | Typical range in San Marino |
|---|---|
| Standard cylinder rekey | $65 – $120 per lock |
| Mortise lock rekey (1920s-1930s estate hardware) | $100 – $180 per lock |
| Multiple locks keyed alike | $65 – $150 per lock |
How long does a rekey take in San Marino?
Most San Marino rekey jobs take 15 to 30 minutes per lock once we’re on site. Mortise locks from the 1920s and 1930s can take longer if pins are seized or the strike plate needs realignment. Call (877) 358-5506 for a time estimate on your specific hardware.
Can you rekey locks without replacing the original hardware?
Yes, and that’s our default approach in San Marino. We pin the existing cylinder to accept a new key, leaving the original brass plate, knobs, and mortise body intact. Full replacement is only suggested when the hardware is genuinely beyond repair, which is rare.

What San Marino Customers Say
"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."
— Miguel Salazar"Does good work. Card payment was a bit of a production, so have another option handy."
— Tamika Ellison"Locked out at eleven at night with a kid asleep in the car. He was there in 25 minutes, had the door open in under two, and did not do the thing where the price goes up once he's standing in front of you."
