Medeco Lock Rekeying: The New York Owner’s Guide
Medeco lock rekeying in New York typically runs $45-$85 per cylinder for residential deadbolts and knobs, with high-security rim cylinders and commercial mortise cores landing at $75-$140, all quoted in writing before we dispatch. We stock Medeco key-in-knob, deadbolt, and rim cylinder pinning kits on every service vehicle, and most residential rekeys in Manhattan, Brooklyn, and Queens are completed same day. Most owners discover their Medeco needs rekeying after a move, a lost key, or a tenant turnover, when they realize the local hardware store can’t duplicate Medeco blanks on standard key machines.
Which Medeco Models This Applies To
Medeco builds several cylinder families, and the rekeying approach differs by series. The residential line most common in New York apartment buildings is the Medeco3 (sometimes marked “M3”), identifiable by a small “M3” stamp on the face of the cylinder and a keyway with angled cuts plus a sidebar slot. Older buildings, especially pre-war co-ops on the Upper West Side and in Forest Hills, may still run original Biaxial cylinders, keyed on two angled axes with a different blank entirely. Commercial doors in Midtown and DUMBO often carry Medeco X4, a pin-tumbler hybrid that accepts conventional key blanks but retains Medeco’s restricted keyway.
We rekey all three. The critical compatibility gotcha: Biaxial and M3 cylinders use different key blanks and pinning kits. A technician who doesn’t check the face stamp can pin an M3 cylinder for Biaxial keys and leave you with a lock that won’t accept the new key. We verify the series before quoting, because the parts cost differs, and Haven Standard Clause 1 says the price on the phone is the price on the invoice.
OEM Medeco bottom pins, master pins, and springs are what we carry. Aftermarket pinning kits exist for Medeco, but the tolerances on the angled cuts and sidebar geometry are tight enough that we’ve seen third-party pins bind in humid summer conditions, which in New York means August in a pre-war building with no central air. We use factory pins and document the part numbers on your invoice.
Signs Your Medeco Lock Rekeying Is Failing

- The key turns but doesn’t retract the deadbolt. The tailpiece connector between cylinder and bolt mechanism has slipped or sheared. On Medeco deadbolts installed in doors that swell seasonally, this is common after five to seven years of summer-winter expansion cycles.
- The key works in one direction only (lock or unlock, not both). A master pin has walked out of position or a bottom pin has developed a flat spot. Medeco’s sidebar design masks this longer than standard cylinders, so by the time you notice, two or three pins are usually out of spec.
- The key requires jiggling or repeated attempts. Dirt, oxidation, or worn pin chambers are creating drag. In New York, road salt tracked into building entryways in January finds its way into cylinders by March.
- A new key copied at a non-authorized dealer doesn’t work. Medeco blanks require specific key machines; a poorly cut duplicate can damage the pins. We see this after owners try chain hardware stores that don’t stock Medeco-certified equipment.
- You’re moving into a pre-owned home or apartment and don’t know who has keys. Not a mechanical failure, but the most common trigger for rekeying. With Medeco, you cannot simply swap to a Schlage or Kwikset cylinder without changing the entire lock body, because the mounting dimensions differ.
Replacement Cost & What’s Included
Here is how Medeco rekeying is priced in New York:
| Service | Typical Range |
|---|---|
| Residential deadbolt or entry knob (M3/Biaxial) | $45 - $85 |
| High-security rim cylinder (apartment door, metal frame) | $75 - $110 |
| Commercial mortise cylinder | $85 - $140 |
| Master key system rekey (per cylinder, with master pinning) | $65 - $120 |
| Additional duplicate keys (Medeco restricted blank) | $18 - $28 each |
The range reflects cylinder accessibility (a mortise case in a commercial steel door takes longer than a standard deadbolt), whether the existing pinning is standard or master-keyed, and whether the cylinder needs extraction due to a stuck or broken key. Every quote includes disassembly, pin replacement with OEM components, key cutting on Medeco-certified equipment, reassembly, and function testing. The 365-Day Done Right Promise covers the labor and parts. You receive a written invoice, a photo record of the completed work, and a key control card noting the blank type and key code.
Haven Standard Clause 1: the price on the phone is the price on the invoice. No call-out surcharge, no “it took longer than expected” add-on at the door.
DIY or Call Us?

What you can safely check: confirm the cylinder series by reading the face stamp, verify you have all existing keys, and photograph any stuck or broken key before attempting removal. These steps save time when you call.
Where DIY goes wrong: Medeco cylinders use sidebar mechanisms and angled pin chambers that require specialized followers and pinning trays. Without them, the sidebar springs launch across the room, the bottom pins mix with master pins, and you cannot read the bitting depth by eye. Reassembly without a factory spec key gauge produces a lock that works until it doesn’t, usually at 11 PM. The pins are small, the chambers are precise, and a mis-pinned Medeco cylinder will accept a key it shouldn’t, which defeats the purpose of owning a high-security lock.
We carry Medeco pinning kits, certified key machines, and the right followers on every truck. Call (551) 214-0800 and we’ll quote the exact price for your cylinder type before anyone leaves the shop.
FAQs
How long does a Medeco rekey take?
A standard residential deadbolt or knob cylinder takes 20 to 35 minutes on site, including key cutting. Mortise cylinders in commercial doors or master-keyed systems run 45 minutes to an hour. We stock the parts, so there’s no return trip. Call (551) 214-0800 for a written quote and same-day scheduling.
Can a Medeco lock be repaired instead of rekeyed?
If the cylinder turns smoothly and the only issue is lost or unaccounted-for keys, rekeying is the correct and less expensive fix. If the cylinder binds, the sidebar is damaged, or the keyway is worn, cylinder replacement is necessary. We diagnose this before quoting, not after starting work. Call (551) 214-0800 and we’ll tell you which path applies to your lock.
How long do Medeco pins last in New York’s climate?
In normal residential use, OEM Medeco pins last 15 to 20 years. The limiting factor in New York is usually environmental: buildings without climate control see wider humidity swings, and entry doors on busy streets accumulate more grit. We’ve rekeyed Medeco cylinders in Park Slope brownstones that were original to a 1990s renovation and still functioned perfectly, and we’ve replaced pins in Midtown commercial doors after seven years of heavy traffic. The key is using the correct key, not forcing a poorly cut duplicate.
Do you stock Medeco parts, or is there a wait?
We stock Medeco3, Biaxial, and X4 pinning kits, sidebar springs, and restricted key blanks on every service vehicle. Novak Lock & Security New York is an independent service provider, not affiliated with Medeco, but we maintain factory-authorized access to their key blank distribution. Same-day rekeying is standard, not an upgrade.
