We provide independent Medeco locksmith service across Crestline, and the thing that separates our Medeco work here from anywhere else is the vacation-rental key control problem. Cabin doors in Crestline get re-keyed or swapped to keypads between guests constantly, and a restricted-key Medeco system only works if that turnover is documented and handled correctly. Our techs know Medeco cylinders from the original classics to the current Maxum line, and we service them throughout the 92325 ZIP code. Call (866) 497-9415 when a Medeco lock stops behaving the way it should.
Why Crestline Residents Choose Us for Medeco Service
Most locksmiths can change a knob. Far fewer can diagnose why a Medeco Biaxial plug has seized after a winter of Crestline ice, then re-pin it to a new restricted key without losing the security the owner paid for. We also provide Lake Arrowhead Medeco service for cabins at similar elevation. We work on the lock in front of us, not just the brands we prefer, and Medeco is one we know cold.
Gil Tanner, our owner, has spent the better part of three decades working locks across the Inland Empire, from residential rekeying to commercial high-security installs. He built the business on explaining what was done and why, not just handing over an invoice. That matters when you own a Medeco system and need straight answers about whether to re-pin, replace, or retrofit. For more on how we handle Medeco sales & service across the region, that background is useful.
We’re an independent shop. We are not authorized or endorsed by Medeco, and we don’t pretend otherwise. What that means is we diagnose the lock on your door and tell you what it actually needs, rather than steering you toward a factory replacement because it’s easier for us.

Common Medeco Locksmith Problems We Solve in Crestline
- Frozen or seized Medeco cylinders in winter. At 4,600 feet, Crestline gets real cold, and ice inside a restricted Medeco keyway will stop a key from turning completely. We thaw, clean, and re-lubricate with a dry lubricant so the mechanism rotates freely again. Oil-based sprays make this worse by trapping moisture.
- Deadbolts binding on warped cabin doors. Older Crestline cabin doors warp and sag, and when the door shifts, the Medeco bolt no longer lines up with the strike plate. The lock itself may be fine. We re-align the door, adjust the strike, and often install reinforcement plates so the problem doesn’t return next season.
- Lost restricted keys from short-term guests. A guest checks out and the Medeco key walks away with them. Without the original key card, that key can’t be duplicated at a hardware store. We re-key the cylinder to a fresh restricted key and document the change so you know exactly how many keys exist for your Crestline rental.
- Sticky rotation from years of mountain moisture. Hardened Medeco pins and springs corrode over time in humid mountain air, and the key starts to stick partway in or the plug turns grudgingly. We clean and re-pin when salvageable, and we’ll tell you plainly when a cylinder has reached the point where replacement is the only way to keep the restricted-key security intact.
- Forced or damaged cylinders after a lockout attempt. We see this on Highway 18 cabin calls, where someone arriving late has tried to force a Medeco deadbolt that was iced or simply the wrong key. The hardened plug resists, but it gets damaged in the attempt. We repair or replace, then often recommend a keypad changeover for rental use.
Medeco Service in Crestline: What Local Conditions Mean for Your Equipment
Here’s something a generic Medeco page won’t tell you: because so many Crestline cabins sit vacant for weeks or months between visits, the biggest vulnerability isn’t the lock itself, it’s the key control around it. A Medeco restricted-key system is only as secure as the record of who has a key. When a cabin cycles through a half-dozen short-term rental guests in a summer, the owner often has no idea how many copies are floating around. A documented re-key between guest rotations plus a keypad changeover is the actual fix, not just cutting another dupe. We see this pattern on cabins along Highway 18 and the side roads off it every single week during peak season. The owners who handle it are the ones who treat re-keying as part of the turnover checklist, right alongside new linens and a clean fridge.
Medeco Models & Products We Service in Crestline
We service the Medeco lines actually found on Crestline doors: the Original classic cylinder, the Biaxial deadbolt, the Maxum deadbolt, and KeyMark / KeyMark SL systems. We stock genuine Medeco cylinders, pins, and restricted key blanks where the system calls for them, and we use aftermarket hardware only for non-security trim and reinforcement plates. If a cylinder is too corroded to hold a re-pin, we’ll say so and explain what replacement costs before any work happens. Genuine parts matter on high-security hardware. Aftermarket internals can undermine the restricted-key protection you paid for.
Medeco Service Pricing in Crestline
Medeco service in Crestline generally falls between $120 and $340 depending on the work. A standard service call and cylinder cleaning sits at the lower end. A full re-key to a new restricted key runs higher, and replacing a worn Maxum or Biaxial deadbolt costs more still. What drives the price is parts and cylinder condition, not your address. We quote the full price on the phone before anyone is dispatched, and that is the price on the invoice. There’s no surprise call-out fee added when we arrive. Call (866) 497-9415 and tell us what lock you have and what it’s doing, and we’ll give you a real number.

FAQs – Medeco Locksmith in Crestline
Yes, if you have the original key card that came with the system, we can cut a replacement restricted key. If the card is lost, as often happens when a cabin passes between multiple owners, we can’t duplicate the key, but we can re-key the cylinder to a new restricted set and issue you new cards. That’s usually the better move anyway, since it resets your key control. Call (866) 497-9415 and we’ll walk you through what you have.
Crestline’s winter cold and moisture get inside the restricted keyway and the cylinder plug, freezing the pins so the key won’t turn. We thaw the lock, clean out any corrosion, and re-lubricate with a dry lubricant that won’t trap moisture the way oil does. It’s a quick service call usually, and it’s far cheaper than letting someone force the lock and damage the plug.
For most Crestline vacation rentals, we recommend keeping the Medeco deadbolt and adding a keypad lock for guest entry. The same setup works for Medeco repair in Muscoy properties with similar guest turnover. The Medeco stays as the physical security layer with restricted keys that no one can casually copy, and the keypad handles the coming-and-going of guests. You change the code between stays instead of re-keying every week, and your key control stays documented. We install both and set them up so they work together.
All the time. Many Crestline cabins were built decades ago with doors that are no longer standard size or that have shifted over the years. A Medeco deadbolt on a 1970s A-frame door with a sagging frame often binds, not because the lock is failing but because the door geometry has changed. We re-align the door and adjust the strike so the bolt seats cleanly, and we’ll reinforce the frame if it needs it. A lock is only as good as the installation behind it.
No, we’re an independent locksmith. We are not authorized or endorsed by Medeco. That actually works in your favor on service calls, because our recommendation is based on what your lock needs, not on what the factory would prefer to sell you. We work on Medeco in San Bernardino county daily and use genuine Medeco parts where the system calls for them.
