Medeco Car Key Cutting: The Los Angeles Owner’s Guide

Medeco car key cutting in Los Angeles typically runs $180-$340 installed, depending on whether your vehicle uses a standard Medeco mechanical key or the newer M3+ sidebar system with chip programming. We stock both key blanks and cutting equipment on our trucks, and most Medeco automotive keys are cut and tested while you wait. Most Los Angeles owners discover their Medeco key is failing when the ignition starts sticking in Silver Lake morning humidity or the key won’t turn smoothly after years of pocket wear along the 405 commute.

Which Medeco Models This Applies To

Medeco’s automotive line breaks into three eras, and getting the right blank matters. The classic Medeco Biaxial system, common in 1990s and early 2000s fleet vehicles, uses angled pin tumblers with a sidebar. The Medeco Original line carries the familiar angled cuts but without the sidebar mechanism. The current M3+ system layers in a slider and electronic programming for newer vehicles with immobilizer systems.

We identify your system by the bow shape, the keyway groove pattern, and whether your ignition requires a transponder chip. The Biaxial bow is wider with the Medeco logo stamped deep; M3+ keys carry a small “+” mark near the shoulder. Aftermarket blanks exist for Biaxial and Original lines, but M3+ keys require factory-authorized blanks with embedded chip programming - a compatibility gotcha that sends some Los Angeles locksmiths back to the warehouse mid-job. We stock OEM Medeco blanks for all three systems and keep a programming unit for M3+ transponder matching. Strongbox Lock & Safe Co. is an independent service provider, not affiliated with Medeco, though we have worked with their hardware since the 1980s.

Signs Your Medeco Car Key Cutting Is Failing

• The key sticks or hangs in the ignition, especially on cooler mornings. Medeco’s angled pin design is precise, but that precision means wear at the cut angles creates drag. In Los Angeles, where overnight temperature swings of 30 degrees are common from the Valley to the basin, metal expansion exaggerates the fit problem.
• You find yourself jiggling the key to find the sweet spot. This usually means the sidebar pocket in a Biaxial or M3+ key has worn oversize. The sidebar no longer seats cleanly, so the key turns only when the angles align by chance.
• The key turns but does not start the car. On M3+ systems, this points to transponder chip failure or de-synchronization after a battery replacement. The mechanical cuts still work; the electronic handshake does not.
• Visible cracking or splitting at the bow or shoulder. Medeco keys are brass alloy, and years of ring rotation weakens the metal. We see this often in older Los Angeles vehicles parked in direct sun, where dashboard heat cycling accelerates metal fatigue.
• A new duplicate works worse than the worn original. This is the classic sign of a poorly cut copy. Medeco angles are cut to 15 and 45 degrees with tight tolerances; a standard key machine without Medeco-specific jaws produces a “close enough” key that never seats right.

Replacement Cost & What’s Included

What moves the price: M3+ blanks cost more, and the programming step adds time. If your ignition cylinder itself is worn, a new key won’t fix the underlying problem - we’ll tell you before we cut. Every Medeco key job carries our 90-Day Done Right Promise, backed in writing. The price we quote on the phone is the price on the invoice. Seniors and veterans receive 5% off.

DIY or Call Us?

There is no dangerous tension or electrical hazard in key cutting itself, but the precision is unforgiving. A Medeco key cut even slightly off will damage your ignition pins over time, turning a $200 key into a $600 cylinder replacement. You can safely check: whether your key says Medeco on the bow, whether the sticking is the key or the lock (does a spare work better?), and whether your vehicle requires a chip.

Where DIY goes wrong: home key machines and big-box kiosks lack Medeco-specific angle guides. The blank looks right but never operates right. We have re-cut dozens of these in Los Angeles, and the owner always paid twice. If your Medeco key is failing, call (877) 664-8139. We’ll confirm your system over the phone, quote the exact price, and cut it properly the first time.
