Medeco Lock Rekeying: The Maryland Owner’s Guide

Medeco lock rekeying in Maryland typically runs $145-$285 installed, depending on cylinder type and whether it’s a single deadbolt or a full set with matching keys. We stock Medeco-compatible pinning kits and key blanks on every truck, and most residential rekeys in Maryland are finished same day. Homeowners usually discover they need a rekey after a move, a lost key, or a contractor change - or when the key starts sticking because the original pins have worn out of spec after fifteen or twenty years of use.

Which Medeco Models This Applies To

Medeco has built several cylinder lines over the decades, and the rekeying approach differs for each. The original Medeco Biaxial system, still common in Maryland homes built between 1985 and 2005, uses angled pins and sidebar fingers that require a specific pinning kit - not interchangeable with standard Schlage or Kwikset tools. The newer Medeco M3 and X4 lines add a slider element, which means the rekey kit must include slider blanks as well as bottom and master pins. The Medeco Maxum deadbolts we see most often in Baltimore County and Howard County use the M3 core.

To identify what you have, check the face of the cylinder for a small stamped model code, or look at the key bow - Biaxial keys have a distinctive angled shoulder, while M3 keys carry a small dimple near the tip. We carry both OEM Medeco pinning kits and quality aftermarket equivalents from LAB and HPC. For a rekey, the aftermarket pins meet the same tolerances and cost less, but if you’re adding a cylinder to an existing master key system, we recommend OEM to guarantee bitting compatibility. One Maryland-specific gotcha: the humidity cycles here, especially near the Chesapeake, can cause corrosion in older Biaxial cylinders that makes pin chambers sticky - if we find that during disassembly, we’ll tell you before we proceed.

Signs Your Medeco Lock Rekeying Is Failing

• Key sticks or requires jiggling to turn. The original pins have worn unevenly, or accumulated grime from Maryland’s pollen-heavy springs has thickened the lubricant. A rekey replaces the worn pins and restores smooth rotation.
• Key turns but the bolt doesn’t retract fully. This often means the tailpiece or cam has worn out of alignment with the cylinder, not the pins themselves. We check this during rekeying and replace the tailpiece if needed.
• Different keys now open the same lock. Extreme pin wear can reduce the number of active shear lines, making the cylinder easier to pick or accidentally key alike. This is a security failure, not just an annoyance.
• Key breaks off in the cylinder. Medeco brass keys work-harden over decades and become brittle. The broken key extraction is separate, but the rekey gives you a fresh key with proper bevels.
• You’ve lost track of who has copies. The most common reason we get called. A rekey renders all old keys useless without replacing the hardware - the right choice when the lock body itself is sound.

Replacement Cost & What’s Included

Here’s how Medeco rekeying breaks down in Maryland:

• Single cylinder rekey (deadbolt or knob): $145-$185
• Two cylinders keyed alike: $225-$285
• Additional cylinders matched to same key: $65-$95 each
• Master key system setup (per cylinder): $185-$245

The range depends on cylinder complexity - Biaxial takes longer to pin than standard X4 - and whether we need to extract a broken key or clean corrosion first. Every rekey includes new bottom pins, top pins, springs, a new key cut to factory spec, and lubrication with Houdini Lock Lube, which holds up better in Maryland’s humidity than graphite. We quote flat on the phone before we roll. The work is covered by our 90-Day Done Right Promise - backed in writing, no arguing, no extra paperwork.

DIY or Call Us?

Medeco cylinders are not beginner-friendly. The angled pins in Biaxial and M3 systems require a follower tool and a pinning tray with specific gauges - without them, the sidebar springs launch across the room and the cylinder is ruined. We’ve had Maryland homeowners bring us cylinders in a ziplock bag after a YouTube attempt. The pins are also restricted; legitimate Medeco blanks and pinning kits require locksmith credentials to purchase.

What you can safely check: verify the key number stamped on the key bow, and confirm the cylinder face turns smoothly with the door open. If it binds only when the door is closed, the problem is likely strike alignment, not the cylinder. For everything else, call us. Tell me what you need, I’ll tell you what it costs, and we’ll get it done right.
