How Medeco Products Fail – and How We Fix Them

• Medeco M3 and Biaxial cylinders with worn key pins. Medeco keys operate by lifting and rotating pins, so when pins wear, keys start feeling gritty or refuse to turn at all. We see this a lot in older Los Angeles office buildings where the same keys have been in daily use for a decade. Our fix is a full pin replacement using factory-cut Medeco pins, then re-cutting keys to match, so the lock returns to factory tolerances instead of limping along.
• Medeco X4 and M3 mortise cylinders that seize up in coastal air. Buildings within a few miles of the ocean get salt and moisture inside the cylinder body, especially on storefront doors that face the street. The symptom is a key that inserts fine but won’t rotate smoothly. We disassemble, clean, and re-lubricate with a dry graphite-based lubricant that doesn’t attract the fine dust that wet oils collect. In severe cases, we replace the cylinder core and preserve the existing Medeco keyway so your keys still work.
• Broken or bent Medeco keys in high-turnover properties. Medeco keys are solid brass and harder than standard hardware store keys, but they still snap when forced. We cut replacement Medeco keys on-site from the original key code or by decoding an existing key, then verify the new key operates every cylinder in the system before we leave. A snapped key extraction from a Medeco cylinder is a routine job for us.
• Panic bars with Medeco rim cylinders that no longer retract the latch. On commercial exit devices, the weak point is typically the tailpiece connecting the Medeco rim cylinder to the panic bar mechanism. When the tailpiece rounds off, the key turns but nothing releases. We replace the tailpiece and clock the cylinder correctly so the key throw matches the exit device’s throw. This is a parts-specific repair, and we keep common tailpieces in the truck.
• Master key systems that have drifted after years of ad-hoc rekeys. If your Los Angeles property has been rekeyed by several different locksmiths over the years, odds are your master key no longer operates every door it’s supposed to. We audit the system, chart what each key currently opens, and restore the hierarchy with a documented pinning chart. When we’re done, you get a written record of which keys open which doors, and every cylinder’s pinning is mapped for future rekeys.

Our Medeco Commercial Locksmith Process

1. 1
   You call, a person answers. You describe the Medeco issue. We ask for the model line if you know it (M3, Biaxial, X4), plus the door type and whether it’s an office door, storefront, or exit device. If you don’t know, a photo over text settles it in seconds.
2. 2
   We quote a written price range on the phone. You’ll get a specific dollar range for your Medeco repair before we dispatch. The full price is confirmed in writing before any work starts. No exceptions.
3. 3
   A background-checked, uniformed technician arrives. You get a live trackable arrival time, so you’re not standing around a four-hour window. The tech who shows up is the same person whose arrival you watched on the tracking link.
4. 4
   Diagnosis and parts decision. We open the Medeco lock and show you what failed. If replacement parts are needed, we use OEM Medeco components when they’re available and when they’re the right call for the job. If a quality equivalent part makes more sense for your specific lock, we tell you why and confirm the price before proceeding.
5. 5
   Repair, test, and document. We repair or replace the damaged component, then test the lock with every key that should operate it. Before we leave, you get before-and-after photos and a written guarantee on the repair.
6. 6
   Digital invoice with a pay link. You pay the exact price we quoted. The invoice lands on your phone. If the repair fails within a year, we come back free under the 365-Day Done Right Promise.

What Medeco Commercial Locksmith Costs in Los Angeles

Medeco commercial work in Los Angeles runs the full range depending on what failed. Here’s what you can expect:

• Medeco cylinder rekey: $35 – $75 per cylinder, depending on whether we’re doing a simple pin swap or restoring a drifted master key system. Includes new keys.
• Broken key extraction from a Medeco cylinder: $75 – $150, assuming the cylinder itself isn’t damaged. If the key snapped because the pins were seizing, the cylinder may need a rebuild, which adds $25 – $50.
• Medeco mortise cylinder replacement: $120 – $220 installed, depending on cylinder type and finish. We keep common Medeco mortise cylinders in stock in our Los Angeles trucks.
• Panic bar repair with Medeco rim cylinder: $180 – $350, depending on whether we’re replacing the rim cylinder, the tailpiece, or rebuilding the exit device’s latch assembly.
• Master key system audit and re-pin: $200 – $600 for a small to mid-size Los Angeles property, depending on cylinder count and how far the system has drifted. Includes full documentation.

What moves the price: cylinder type (mortise vs. rim vs. KIK), whether we’re preserving an existing master key structure, and whether OEM Medeco parts are required. You’ll know the exact number before we start. Call (409) 405-4485 for a free estimate on your specific Medeco job.
