We service and rekey Medeco high-security cylinders and deadbolts across South Pasadena, including the pre-1935 Craftsman and Spanish Colonial homes that still carry their original mortise locks. We also provide Medeco repair in Alhambra and surrounding communities. The thing that makes our Medeco work here different is that most of these cylinders have been retrofitted into hundred-year-old doors, and the fit problems that creates are a hardware-preservation issue, not a simple swap. Call (866) 497-9415 if you need a Medeco lock serviced, rekeyed, or evaluated today.
Greystone Locksmith is an independent Medeco service provider. We are not manufacturer-affiliated or authorized, and we don’t pretend to be. What we are is a shop that works on Medeco sales & service hardware weekly, from Maxum deadbolts to restricted-keyway mortise cylinders, and we know how these locks behave when they are installed in doors built before 1935.
Why South Pasadena Residents Choose Us for Medeco Service
Gil Tanner built his reputation on residential rekeying and commercial high-security installs, and he’ll tell you the same thing his instructor at Riverside City College told him decades ago: a locksmith is really just a problem-solver who happens to carry better tools. That’s how we approach Medeco work in South Pasadena. These are excellent locks, but the installation behind them matters as much as the hardware. A lock is only as good as the installation behind it.
What you get when you call us is a technician who has actually serviced Medeco cylinders in the exact doors South Pasadena is full of. We know which mortise cases from the 1920s can accept a Medeco cylinder cleanly and which ones are too far gone. We stock genuine Medeco pins and cylinders for restricted keyways, and we carry the aftermarket strikes and reinforcement plates that make sense when the original body is sound. And we show up prepared, not guessing.

Common Medeco Locksmith Problems We Solve in South Pasadena
- Summer door-swell binding on old-growth slabs. A Medeco mortise cylinder retrofitted into a 1920s Craftsman door will bind every August when the old-growth wood swells in the heat. The key turns, but the bolt drags against the strike. We service the case and re-align the strike so the lock works through the dry season without forcing the door.
- Santa Ana grit in the keyway. Those wind events drive fine dust and grit into exposed Medeco keyways on front and side doors. The result is a stiff, gritty turn that homeowners sometimes mistake for a failed lock. Usually the cylinder just needs stripped down, cleaned, and re-lubricated with the right dry lubricant, not replaced.
- West-sun oxidation on exterior cylinders. Doors facing west along Mission Street and up on Raymond Hill take direct afternoon heat. The dry climate seizes exterior Medeco cylinders through oxidation and dust accumulation far more often than salt corrosion would in a coastal city. Again, cleaning and proper lubrication usually resolves it.
- Restricted keyway with missing records. We regularly meet South Pasadena homeowners who bought a house with Medeco restricted-keyway cylinders already installed, but the prior owner never passed along the control card. Without that documentation, you have a functioning high-security lock you can’t legally get rekeyed. We can help you establish new key control through the proper channels.
- Invisible retrofit into period mortise trim. The historic district here changes the job. Owners on Diamond and Adelaine want the original skeleton-key escutcheon to stay put while a Medeco cylinder works inside it. That requires mortise cylinder work, not a standard tubular deadbolt install, and it has to look untouched from the sidewalk.
Medeco Service in South Pasadena: What Local Conditions Mean for Your Equipment
Here is the thing about South Pasadena specifically. The 91030 ZIP is dominated by pre-1935 Craftsman and Spanish Colonial homes, and many still carry their original mortise locksets. South Pasadena’s historic design review covers visible front-door hardware in the National Register district, so when a homeowner on a street like Adelaine wants a Medeco deadbolt, the retrofit has to be invisible from the sidewalk. The original period trim stays. The Medeco cylinder goes inside the existing mortise lock or gets fitted into a mortise prep that respects the door’s original lines. You cannot just bore a 2-1/8-inch hole through a 1923 front door and hang a modern tubular deadbolt on it without running afoul of the city’s design standards, and frankly, it looks wrong. That is why our Medeco work in South Pasadena is so often cylinder work, not full lock replacement, and why we service the original mortise case rather than condemning it. A strip-mall locksmith would swap the hardware. We work on the lock in front of us.
The climate adds another layer. Santa Ana events push fine grit into restricted pin chambers, and the dry heat warps old doors enough to throw off strike alignment for months at a time. A Medeco deadbolt is precise hardware. When the door moves a quarter-inch between July and January, that precision works against you unless the strike is re-aligned for the season. We have had a Craftsman on Adelaine where the original skeleton-key mortise was still in the door, and a previous owner had fitted a Medeco cylinder that bound every August. We serviced the mortise case, cleaned the restricted pin chambers after the last wind event, and re-aligned the strike so the latch engaged cleanly through the dry season. The visible hardware stayed exactly as the owner wanted it, untouched and period-correct.
Medeco Models & Products We Service in South Pasadena
We service the full residential Medeco range you are likely to find in South Pasadena homes. That includes the Medeco Maxum residential deadbolt, the Maxum EcoLuxe, the Medeco Original/Classic high-security cylinder in both rim and mortise configurations, and the Medeco KeyMark restricted-keyway cylinder. On parts, our approach is straightforward: we use genuine Medeco cylinders, pins, and keys for anything in a restricted keyway, because that is where key control actually matters. For strikes, reinforcement plates, and jamb hardware on an older door, we’ll use quality aftermarket parts where the original mortise body is still sound and the upgrade makes practical sense. If the antique mortise case is cracked or a past retrofit already butchered the door prep, we will say so plainly. Pinning a restricted cylinder into hardware that won’t hold it is a waste of your money.
We keep common Medeco pins and cylinder components stocked locally for fast turnaround across South Pasadena service area, which means less waiting on parts and more same-day rekeying when you need it.
Medeco Service Pricing in South Pasadena
San Marino Medeco service and South Pasadena pricing typically runs $140 to $310 depending on what the lock needs. A standard service call and rekey of an existing Medeco cylinder usually falls between $140 and $220. Adding a new Medeco mortise cylinder or Maxum deadbolt pushes the job into the $250 to $450 range, with the higher end reflecting period-door mortising work and invisible retrofit into original trim. If we are restoring a full antique mortise case and re-aligning the strike on a swollen Craftsman door, you are looking at $180 to $340 including labor and parts on-site.
What drives the cost is whether the mortise case is sound, whether the keyway is restricted, and how much fitting the old door requires. A free estimate tells you exactly which of those apply to your situation. Call (866) 497-9415 and we’ll quote the full price before anyone is dispatched. That is the price on the invoice.

FAQs – Medeco Locksmith in South Pasadena
In most cases, yes. The original mortise case on a 1920s Craftsman is often still mechanically sound, and a Medeco mortise cylinder can be fitted into it with the proper cam and tailpiece alignment. The original skeleton-key trim stays on the outside, so the lock looks period-correct from the sidewalk. What we need to confirm on-site is that the case itself has not cracked and the door prep has not been butchered by a prior retrofit. If the case is shot, we’ll tell you before we pin anything into it.
That is the old-growth door slab swelling in the dry heat. South Pasadena’s 1900 to 1930 doors are thick, solid wood that moves with the seasons, and when the slab swells, the bolt no longer aligns with the strike. The lock itself is usually fine. The fix is servicing the mortise case, possibly cleaning swollen edges on the strike, and re-aligning so the latch engages without forcing. We see this pattern every August on Mission Street and Raymond Hill. Call (866) 497-9415 and we’ll diagnose it before you replace a lock that never needed replacing.
If you are swapping visible front-door hardware on a property in South Pasadena’s National Register district, design review can apply. The practical way around the hassle is to keep the period trim and escutcheon in place and fit the new cylinder inside the existing mortise lock, which usually does not trigger a visible-change review. That is exactly the retrofit we do most often for Medeco owners here. We work within the district’s constraints every week, so we know what passes and what does not.
Without the original control card and key records, you cannot legally get the restricted keyway rekeyed through normal duplication. The lock still works, but you cannot produce new keys with proper key control established. We walk South Pasadena homeowners through the process of establishing new key control for the existing cylinder, which often means replacing the cylinder outright with new restricted keying and a fresh card in your name. It costs a bit more than a standard rekey, but you end up with a system you actually control. Call (866) 497-9415 for an exact quote based on your existing hardware.
Yes. We run emergency locksmith coverage for South Pasadena on weekends, and a Santa Ana-jammed Medeco keyway is the kind of call we handle. Often the cylinder just needs the grit blown out and the pins cleaned rather than a full rekey, but if you want new keys anyway after a security concern, we can rekey the same visit. Call (866) 497-9415 and we’ll sort out what the lock actually needs before quoting a price.
