We’re an independent Medeco locksmith serving San Marino, and the short answer is this: we service, rekey, and install Medeco cylinders and deadbolts across 91108 and 91118, and the reason our Medeco work here is different comes down to one thing. San Marino’s estates are full of original mortise bodies, design-review constraints, and restricted keyways that most locksmiths never see. If you need a Medeco cylinder fitted into a 1920s door without altering its face, call us at (866) 497-9415. We do it weekly.
Why San Marino Residents Choose Us for Medeco Service
San Marino isn’t a place where you bolt on a modern deadbolt and call it done. The homes here were built with intentions. Spanish Colonial entries off Lombardy Road, Tudor doors off Oak Knoll, Mediterranean wrought iron on Orlando Road – these are doors that deserve a technician who knows when to preserve and when to upgrade. Our owner, Gil Tanner, spent the better part of three decades working locks across Southern California, and he’ll tell you the same thing his instructor at Riverside City College told him: a locksmith is a problem-solver who happens to carry better tools. That’s what Medeco work in San Marino requires most days – problem-solving, not hardware-swapping.
We stock genuine Medeco cylinders and restricted key blanks for the models this market actually uses. We carry vintage-style cylinders for older mortise bodies. We know the difference between a cylinder that needs cleaning and one that needs replacing. And because we work on eight major lock brands, from Schlage and Kwikset up through Medeco, Mul-T-Lock, and Abloy, we’re not going to talk you into a system you don’t need. Our Medeco sales & service work is built on judgment, not a factory badge.

Common Medeco Locksmith Problems We Solve in San Marino
- Dust-clogged restricted keyways on gate and entry cylinders. Santa Ana winds push fine grit into pin chambers, and a Medeco key stops turning cleanly. Owners often think the lock is worn out when it just needs a proper cleaning and re-lubrication. We see this on gate locks along St. Albans Road every fall.
- Deadbolts binding after winter rain swells the door. San Marino’s dry summers keep doors stable, but a rare heavy rain soaks walnut and oak, the wood swells, and a Medeco deadbolt that aligned perfectly in August suddenly won’t throw. The fix is usually strike-plate adjustment, not a new lock.
- Medeco cylinders retrofitted into original solid-brass mortise bodies. The cylinder is fine; the surrounding antique hardware is what fails. Old mortise internals drag, alignment drifts, and the whole assembly feels loose. We rebuild the mortise prep and re-seat the cylinder properly.
- Lost key-control cards on estate purchases or after staff turnover. A restricted Medeco keyway can’t legally be duplicated until ownership and authorization are re-established. When a San Marino estate changes hands or a housekeeper leaves, we handle the re-verification and rekeying so the system is secure again.
- Medeco deadbolts on heavy wood doors with worn hinges. A 70-pound door on sagging hinges will grind any deadbolt into its strike. We align the door first, then the lock. It’s the only order that works.
Medeco Service in San Marino: What Local Conditions Mean for Your Equipment
Here’s the part that doesn’t show up on generic locksmith websites. San Marino’s design-review standards mean visible exterior hardware changes on estate entries often need to respect the city’s architectural expectations. So Medeco upgrades here are frequently hidden inside the original mortise prep or matched to period brass, rather than bolted onto the door face. That’s a constraint most cities don’t have. Pasadena doesn’t care if you drill a new deadbolt into a 1930s door. San Marino does. When a homeowner off Oak Knoll wanted staff-turnover rekeying plus a keypad for the housekeeper, our tech rebuilt the mortise prep, seated a Medeco high-security cylinder behind the original trim, and set a discreet keyless entry on the service door. The door face never changed. Then we walked the estate manager through the restricted key-control chart. That’s the San Marino version of a locksmith visit: estate management, not emergency repair. A lock is only as good as the installation behind it.
Medeco Models & Products We Service in San Marino
We work on the Medeco Maxum deadbolt, KeyMark and KeyMark XT cylinders, M3 and M4 high-security cylinders, and deadbolt retrofits into original mortise locksets. On restricted keyways, we fit genuine Medeco cylinders and key blanks only. An aftermarket restricted key defeats the entire point of the system, and we won’t do it. On antique mortise bodies, we source period-correct brass and vintage-style cylinders rather than forcing a modern deadbolt onto a historic door. If your cylinder is sound, we clean and re-pin it. We recommend replacement only when the plug, pins, or keyway are genuinely worn, or the door prep can no longer hold a high-security cylinder. For San Marino turnaround, we keep the common Medeco key blanks and cylinders stocked locally, which means most jobs don’t wait on a parts order.
Medeco Service Pricing in San Marino
Medeco service in San Marino runs on straightforward numbers, not vague estimates. A standard Medeco rekey on an existing cylinder typically lands between $35 and $60 per cylinder, labor included. New Medeco cylinder installation runs $120 to $250 per cylinder depending on the door prep and whether we’re working with a standard prep or a vintage mortise body. Adding a keyless entry system on an estate gate or service door generally falls between $180 and $400, and that varies with the hardware grade and whether we’re tying it into an existing access system. If you need a full mortise-body rebuild around a Medeco cylinder, expect $250 to $400 for the restoration work.
What drives the cost here? The door. A 1920s walnut door with original brass is a different job than a side door from 2005. We’ll tell you on the phone what the work involves and what it will cost. No call-out fee on top, and the price we quote is the price on the invoice. Call (866) 497-9415 for an exact figure – estimates are free.

FAQs – Medeco Locksmith in San Marino
Yes. We rebuild the mortise prep, seat the Medeco cylinder behind the original trim, and the door face stays visually identical. We do this regularly on Spanish Colonial and Tudor entries throughout San Marino. Call (866) 497-9415 and we’ll walk you through it.
Yes, but the first step is re-establishing ownership and authorization for the restricted keyway. Medeco restricted keys can’t legally be duplicated without proper documentation. We verify current ownership with the property records, then rekey the system to a new restricted keyway under your name. Bring what paperwork you have. Call (866) 497-9415 and we’ll tell you exactly what’s needed.
Summer grit from Santa Ana winds packs the keyway with dust, and winter moisture swells the wooden door so the bolt binds against the strike plate. Both are San Marino seasonal patterns, and both are fixable without replacing the lock. We clean, lubricate, and realign.
We install keyless entry on estate gates, service doors, side entries, and front doors. In San Marino, most of our keyless work is on the doors that don’t face the street: housekeeper entrances, garage service doors, and rear gate access. Call (866) 497-9415 for a written scope and a flat per-lock price.
No. We’re an independent locksmith shop, not authorized, sponsored, or endorsed by Medeco. We say that plainly because our value isn’t a factory badge. It’s the judgment to know which Medeco cylinder belongs in which door, and when a lock needs cleaning instead of replacing.
