Stalwart Locksmith is an independent Medeco service provider in Denton, Texas. We rekey, repair, and install Medeco high-security cylinders, deadbolts, and master-key systems across every Denton zip code from 76201 to 76204. What makes our Medeco work different here comes down to one thing: we understand what Denton’s two-university rental cycle does to restricted keyways. Call us at (877) 626-0257.

Why Denton Residents Choose Us for Medeco Service
Medeco is not a brand you hand to someone who learned locksmithing from a weekend video. The restricted keyways, the angled cuts, the hardened steel pins and the master-key math behind a workable system require a level of pinning skill that most general locksmiths never develop. Russ Thibodeau, our owner, built his foundation through the hands-on vocational program at Tarrant County College, and that training informs every Medeco cylinder that crosses our bench in Denton. We are not manufacturer-authorized, and we do not pretend otherwise. We are an independent shop that chose Medeco as a specialty because the hardware genuinely challenges us. For Medeco sales & service in Denton, we bring OEM-grade discipline without the manufacturer’s red tape. When a Medeco Maxum deadbolt or M3 cylinder needs repinning, we treat it as a precision job, not a swap-and-go.
Choosing a Medeco locksmith in Denton means choosing someone who can read a wear pattern on a ten-year-old Original cylinder and tell you whether the pin tumblers are the problem or if your door frame has shifted — the same expertise we bring to Medeco service in Corinth. That matters here, where the housing stock swings from century-old mortise work near the Courthouse Square to brand-new deadbolts in south Denton subdivisions.

Common Medeco Locksmith Problems We Solve in Denton
- Restricted keys copied before move-out. This is the big one in Denton’s student housing. A departing tenant hands off an unauthorized copy, and now the property manager has a cylinder whose key control is technically broken. The lock itself is fine. The security isn’t. We repin the affected Medeco cylinder to a fresh restricted keyway and reissue controlled keys.
- Sticking deadbolts in summer heat. North Texas clay expands and contracts through the year, and by July the shift is measurable at the strike plate. A Medeco hardened bolt that seated cleanly in January can start dragging in August, and because these bolts are so strong, they bind against the misaligned frame rather than giving. The bolt needs trimming or the frame needs adjusting, not a new lock.
- Worn pin tumblers on older Medeco Originals. Century-old doors around downtown Denton and older rentals near the universities often carry Medeco Original cylinders installed decades ago. We see keys that only work when jiggled or turned at an angle. That’s pin tumbler wear, and it is repairable in most cases.
- Master keys that no longer open every door. In master-keyed apartment buildings along the I-35 corridor, grit, heat cycling, and years of tenant key turnover chew at commercial Medeco cylinders. When a building master key stops working across all units cleanly, the pinning chart has drifted or a cylinder has worn out of tolerance. We pull and verify against the building’s chart, then repin what’s drifted.
- Lost or stolen Medeco keys. Restricted keyways mean you can’t run to a hardware store kiosk. When a Medeco key disappears in Denton, the secure response is rekeying the affected cylinder and issuing new controlled keys with fresh biting. We handle that same-day for most residential cylinder sets.
Medeco Service in Denton: What Local Conditions Mean for Your Equipment
Denton’s identity as a two-university town means locksmith work here runs on a rhythm the quiet neighboring suburbs never see. Every August, UNT and Texas Woman’s University flood the city with new renters, and the apartment managers along the I-35 corridor and around the square need batch rekeys and master-key rebuilds done before the first day of class. Every May, the same cycle runs in reverse, and departing tenants leave behind restricted Medeco keys they should not have had copied in the first place. Medeco’s whole design philosophy is key control, and Denton’s move-in/move-out cycle tests that control harder than any other city in this part of the Metroplex. A master-key system that worked perfectly last semester can be compromised by fall simply because thirty restricted keys walked out the door in May.
Last August, a student apartment manager along the I-35 corridor called us. A batch of units had Medeco M3 cylinders whose restricted keys had been copied by departing tenants, and the building’s master key no longer opened every door cleanly. We pulled each cylinder, verified the pinning against the master-key chart, repinned the affected units to fresh restricted keyways, and reissued controlled keys to management the same week. The master key turned cleanly across the whole building again before fall move-in. That kind of turnaround is only possible if you know Medeco pinning math cold and you already understand the deadline Denton landlords are working against.
Medeco Models & Products We Service in Denton
We service the full Medeco line that shows up in Denton homes, apartments, and storefronts. That includes the Medeco Maxum deadbolt, the M3 and M4 keyway cylinders, the Medeco Original classic deadbolt and keyway, and high-security commercial mortise cylinders found on downtown storefronts and master-keyed buildings along the I-35 corridor. For any restricted-keyway system, we use genuine Medeco OEM cylinders, keys, and pins so the key control stays intact. Aftermarket hardware only gets used where it belongs: non-security trim and door-prep items that don’t touch the keyway math. If a worn Medeco cylinder can be repinned or rebuilt, we’ll tell you that plainly. We only recommend full replacement when the cylinder body or keyway itself is compromised beyond repair.
Medeco Service Pricing in Denton
A standard Medeco cylinder rekey in Denton typically runs $65 to $120 per cylinder, with fresh restricted keys cut and issued at the same visit. Medeco deadbolt installation, depending on whether we are retrofitting an existing door or drilling fresh prep, runs $180 to $340 including hardware. Master-key system work is the variable: a full building audit, repinning, and new key issuance runs $500 to $1,800 depending on cylinder count and the condition of the existing system. Commercial mortise cylinder rebuilds fall between $45 and $110 per cylinder in labor when the body is salvageable. Every job gets a firm quote over the phone before dispatch, and that is the price on the invoice. There is no add-on charge when we arrive. Call (877) 626-0257 and we will price your Denton Medeco job in about ten minutes.

FAQs – Medeco Locksmith in Denton
Yes, and we do it constantly during Denton’s May move-out and August move-in windows. We remove the existing cylinder, repin it to a fresh restricted keyway, cut new controlled keys, and verify every door in the unit opens cleanly. The old key becomes useless immediately. This is the single most common Medeco job we run in student housing along the I-35 corridor and around the universities. Call (877) 626-0257 if you are staring down an August 1 move-in with keys that may have walked.
The heat itself is rarely the direct cause. North Texas expansive clay soil shifts through the year, and by summer your door frame or strike plate has moved enough that the hardened Medeco bolt binds instead of throwing cleanly. The bolt is strong enough to resist the misalignment, which is why the lock feels stuck rather than loose. We correct the frame alignment or adjust the strike plate, and the deadbolt works like new. It’s a door problem, not a Medeco problem, most of the time.
Not on the same key, no. A skeleton-key mortise lock and a Medeco cylinder use entirely different key profiles and pinning systems, so a single key cannot operate both. What we can do is install your Medeco cylinder into fresh hardware that sits alongside the skeleton lock, or key the Medeco to its own controlled key while preserving the antique front hardware as-is. If having one key across both matters more than keeping the original hardware, we’ll walk you through the replacement options. The lock either works or it doesn’t, so let’s make sure it works.
Yes. We decode each existing cylinder against its pinning chart, measure current pin stacks, and rebuild the system from what is actually installed in the doors rather than from paper records. We see Denton apartment complexes whose original charts were lost two property managers ago, and the system can usually be salvaged if the cylinders are still physically sound. We’ll tell you honestly whether a rebuild makes sense or whether you are better off starting fresh on new restricted keyways.
No. Stalwart Locksmith is an independent Medeco service provider. We are not a Medeco dealer, not manufacturer-authorized, and not manufacturer-affiliated. We choose to work on Medeco hardware because restricted keyways and master-key systems demand a level of pinning discipline we respect. Our parts are genuine Medeco OEM for anything touching the keyway. Your warranty through an authorized Medeco dealer is separate from our independent labor.
