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

If you need Medeco car key cutting in Los Angeles, we can cut and program most Medeco automotive key blanks the same day, with the fully installed and programmed key typically landing between $85 and $220. That price depends on whether you have the original key to copy, the transponder chip generation, and your vehicle’s year, but the number you’re quoted on the phone is the number on your invoice. Most owners discover they need us when their spare Medeco key is still cut but the chip inside has drifted out of sync, or the blank they ordered online won’t turn in the ignition because it was milled on generic equipment. Kevin Yoon has seen enough of those aftermarket blanks chewed up in L.A. ignitions to know that Medeco’s tighter warding tolerances punish sloppy cutting.

Here’s what matters on this page: we cut Medeco keys that actually turn, we program chips that actually start the car, and the written price comes before anyone drives to you.

Which Medeco Models This Applies To

Medeco’s automotive key line is narrower than their residential and commercial lines, and that’s the first thing to understand. Medeco is primarily a high-security lock manufacturer; in the automotive space, you’re usually dealing with Medeco-cut keys for fleet vehicles, specialty locks, or Medeco’s XT and M3 keyways where they intersect with vehicle applications. If your key has the Medeco logo stamped on the bow and a milled groove pattern that looks more aggressive than a standard Schlage or Kwikset car blank, you’re in the right place.

The compatibility gotcha most Los Angeles owners hit is keyway depth: Medeco keys use angled cuts that standard automotive key machines can’t reproduce accurately. A flat-duplicated Medeco car key might slide into the ignition but bind on the second or third wafer, which feels like a dead battery but is actually a geometry problem. We cut Medeco blanks on equipment calibrated for their specific cut angles, and we match the blank to your ignition cylinder, not just your key’s silhouette. For OEM versus aftermarket: genuine Medeco blanks are worth the upcharge if you have a security-registered fleet key, because aftermarket copies often skip the side-milling that Medeco uses for anti-pick resistance. On basic single-sided Medeco car keys, a quality aftermarket blank with the correct shoulder length and groove spacing works, and we’ll tell you honestly when it’s fine to save the money.

Signs Your Medeco Car Key Cutting Is Failing

• The key turns hard in the ignition but works fine in the door. This usually means the key’s cuts have worn shallow on the ignition-side wafers, or the key was cut slightly off-spec and the door lock is more forgiving. Medeco’s tighter tolerances mean this shows up sooner than on a generic key.
• The key turns the ignition but the car won’t crank. The metal part is cut fine; the transponder chip has lost programming or the key was cut from a blank without the correct chip generation. Your immobilizer is reading “wrong key” and silently refusing to start.
• You ordered a key online and it won’t turn at all. This is the most common one we see. The blank was cut on a generic machine that can’t reproduce Medeco’s angled cuts, or the blank itself is the wrong keyway. Don’t force it; forcing a mis-cut Medeco key can shear a wafer inside the ignition cylinder and turn a $100 key job into a $400 cylinder replacement.
• The key works intermittently, more often when the car is cold. Southern California mornings still get cool enough to shrink the ignition cylinder slightly. If your Medeco key is marginal, it’ll be worst at 6 a.m. and fine by noon. This is wear, not weather.
• You have one working key, and the dealer quoted you $300+ for a spare. That’s the signal most Angelenos call us. Dealership pricing on Medeco-cut keys with transponder programming is routinely double to triple what an independent locksmith with the right equipment charges.

Replacement Cost & What’s Included

In Los Angeles, Medeco car key cutting and programming typically runs $85 to $220 fully installed, and the spread comes down to a few specific things. A basic non-transponder Medeco key copy starts around $85. A transponder-equipped key with chip programming runs $120 to $180 depending on the vehicle. If you need a full key rebuild because your only key is broken or worn past copying, you’re at $180 to $220, which includes decoding the lock, cutting a fresh Medeco key to factory spec, and programming the chip. We do not charge a separate call-out fee, and the price you get on the phone with Kevin or a team member is the price you pay. Every Medeco key job includes the 365-Day Done Right Promise: if the key doesn’t turn or the chip doesn’t sync, we come back and make it right at no charge.

A note on the pricing ranges above: if you have a newer vehicle with a rolling-code or encrypted immobilizer, programming can require a specific tool profile that pushes labor toward the high end. We’ll tell you the exact number before we start, in writing, per The Relay Visibility Guarantee.

DIY or Call Us?

There’s nothing dangerous about cutting a car key the way there is with a garage spring under tension. The risk is financial. Most of the Medeco keys we see that failed were cut by a kiosk or a hardware store machine that couldn’t hold Medeco’s angle, and by the time the owner limps to us, the key is too worn to copy accurately. If you have a clean, factory-cut Medeco original and just want a basic metal spare, a quality automotive locksmith with an angle-calibrated machine can do it in 15 minutes, and you’ll spend about what a kiosk would charge for worse work. What you should not do is force a key that binds, or keep using a key that’s visibly worn at the tip; once it’s too worn to read, you’re paying for a decode instead of a copy. Kevin Yoon says it best: “Real price on the phone. Same price at the door. That’s it.”
