We’re Greystone Locksmith, and we provide independent Medeco service across Placentia: rekeys, repairs, deadbolt upgrades, and new high-security installations. What sets our Medeco work apart here is that we actually understand Placentia’s split housing stock – the Old Town bungalows with original mortise locks and the postwar tract homes with builder-grade cylindrical hardware. That means we know when a Medeco Maxum deadbolt needs a frame repair first, not just a swap. Call us at (866) 497-9415 for a straight answer on your lock.
Why Placentia Residents Choose Us for Medeco Service
Medeco is not a brand you want a generalist guessing at. The keyways are tighter, the pins are hardened, and the tolerances leave little room for error. Gil Tanner, our owner, has spent the better part of three decades working locks across Southern California, from Anaheim Medeco service to Placentia, and he’ll tell you that a lock is only as good as the installation behind it. That’s especially true with Medeco hardware on Placentia doors that have been swelling and shrinking for forty years.
We carry genuine Medeco cylinders, keys, and pins for when factory tolerances matter, and we’re direct about when a worn Maxum deadbolt is better replaced than re-pinned. You get an honest recommendation from someone who has done the work, not a sales pitch. If you’re in the 92870 or 92871 ZIP, we know your block, your door style, and what your lock actually needs. We work on the lock in front of us – not just the brands we prefer.

Common Medeco Locksmith Problems We Solve in Placentia
- Medeco Maxum deadbolts binding in Old Town door frames. Placentia’s hot, dry summers make wood frames swell, and the original mortise or thin door frames on early-1900s bungalows were never built for a Maxum’s throw length. The bolt drags against the strike plate or the frame itself, and forcing the key only bends the tailpiece. We realign, shim, or rebuild the frame before anything else.
- Sticky key rotation from Santa Ana grit. Exterior Medeco cylinders on homes facing the seasonal winds collect fine dust that works into the keyway. M3 and Maxum keys are precision-cut, so once grit wears the key or the pins, the plug starts binding mid-turn. We clean, inspect for wear, and rekey if the cylinder’s tolerance is shot.
- Worn Medeco keys wearing cylinders unevenly. A customer hands us a key that’s been on a ring for ten years, and the cylinder feels like it’s full of sand. Medeco’s hardened keyway means a worn key damages the pins faster than a soft one would. If the key is visibly thinned at the shoulders, we cut fresh from code rather than copy a copy.
- Strike plates loosening on builder-grade doors. A lot of Placentia’s 1960s and 1970s tract homes were drilled for standard cylindrical hardware, and the strike plate screws were only ever into drywall or a thin jamb. When someone upgrades to a Medeco deadbolt, the added weight and tighter fit can pull the strike loose within a year. We reinforce before we install.
- Lost-key rekeys on Medeco M3 and Maxum cylinders. Losing a Medeco key in Placentia isn’t a quick spin of the plug. These cylinders use angled cuts and sidebars, so the rekey requires different pins and a working knowledge of the keyway family. We do it on site, and we cut the new keys before we leave.
Medeco Service in Placentia: What Local Conditions Mean for Your Equipment
Here’s something we see in Placentia that doesn’t show up the same way in neighboring cities like Fullerton: many original Old Town bungalows still have single-cylinder deadbolts with no interior thumb-turn. That’s a violation for rentals under modern safety standards, and it means a Medeco upgrade in those homes isn’t a simple rekey job. The old bolt comes out, the door and frame get checked for decades of seasonal movement, and the new Maxum deadbolt goes in with a compliant thumb-turn on the inside. On a 1920s wood-frame bungalow, that often means repairing the door edge first, because hot summers have bowed the stiles just enough that a precise Medeco bolt won’t sit level without some work. We’ve done this exact upgrade on bungalows around the Old Town core, and the difference after the frame work is immediate – the key turns clean, the bolt throws full length, and the inspection passes. In Placentia, a Medeco job is as much about the door as it is about the cylinder.
Medeco Models & Products We Service in Placentia
We cover the Medeco lines you’re most likely to have on a Placentia door: the Maxum residential deadbolt, the M3 and M3+ high-security cylinders and keys, Maxum rim and mortise cylinders for retrofit on older homes, and the Original and BiLevel keyways still hanging around from installs done twenty or thirty years ago. We keep common Maxum and M3 cylinder parts, pins, and key blanks stocked so we’re not ordering a keyway-specific blank and making you wait. For anything unusual, we source genuine Medeco parts and finish the job when they land. Medeco sales & service is a core part of what we do, independent from the manufacturer.
Medeco Service Pricing in Placentia
Medeco work in Placentia runs higher than standard locksmith service because the parts and the labor are both more demanding. A service call to assess and repair a Maxum deadbolt typically falls between $95 and $160 before parts, and a full rekey with new Medeco keys usually lands in the $25 to $40 per cylinder range for standard keys, more for M3 restricted or high-security blanks. A new Medeco Maxum deadbolt installed generally runs from $220 to $400, depending on whether the frame needs reinforcement and what condition the door is in. We quote the full price on the phone before anyone is dispatched, and that’s the price on the invoice – no call-out surcharge added when the van shows up. Call (866) 497-9415 for an exact quote on your setup; estimates are free.

FAQs – Medeco Locksmith in Placentia
Yes. We rekey Medeco Maxum cylinders on site in Placentia, including cutting fresh keys from code rather than copying a worn one. If the cylinder itself is damaged or the key loss suggests the lock was compromised, we’ll recommend a replacement and tell you why. Call (866) 497-9415 and we’ll give you a firm quote before dispatching.
Usually yes, and it’s a common call for us in Old Town Placentia. Those old single-cylinder bolts don’t meet modern safety codes for rentals, and a Medeco Maxum deadbolt with a compliant interior thumb-turn solves the inspection issue while giving you a far more resistant lock. We’ll check the frame and door edge first, because many of those bungalow doors need repair before the new bolt seats correctly. Call (866) 497-9415 to schedule an assessment.
In Placentia’s hot, dry summers, wood doors and frames expand, and that binds the deadbolt against the strike plate or the frame itself — we see the same pattern with Medeco repair in Yorba Linda. Even a half-millimeter of movement is enough to make a Medeco Maxum plug feel tight. We realign the strike, shim the hinges, or trim the frame so the bolt throws cleanly without forcing it. Call (866) 497-9415 and we’ll diagnose it on site.
Yes, we stock genuine Medeco cylinders, pins, and key blanks for the Maxum and M3 lines, and we use them when you want the factory keyway and tolerances preserved. For older Original and BiLevel keyways, we source genuine parts when they’re available and are direct with you when a worn cylinder is better replaced than rebuilt.
Yes, and that’s a frequent request in Placentia’s mix of owner-occupied and rental properties.
