Key duplication costs in St. Louis vary by key type and complexity.

Professional Key Cutting Process

Keyway & Blank Identification

We measure your original key's bitting depth and keyway profile using calipers and gauges. Your key might use Schlage SC1, Kwikset KW1, Weiser WR5, or one of 200+ residential/commercial blanks we stock. Unusual keyways (like Medeco high-security or vintage mortise keys) may need ordering, adding 1-2 days.

Cutting Methods (1-3 Minutes Per Key)

For standard keys, we use computerized code cutters that read your original optically, then mill each cut to 0.003" tolerance—sharper and more accurate than manual machines. For worn keys, we decode depths manually to cut fresh copies that work better than your original. Car keys with transponder chips get cut mechanically, then chip-cloned separately via our key fob programming service.

Deburring & Lock Testing

Every cut leaves tiny metal burrs that can jam pins inside your lock. We deburr each key with wire wheels and test it in a practice cylinder that matches your lock type. If it binds even slightly, we recut or file it until it slides smoothly with zero resistance—critical for deadbolts that stick when keys aren't perfect. If your key snapped off inside the lock, our broken key extraction service can remove it before we cut a fresh duplicate.

Bulk Discounts & Labeling

Need multiple copies? We offer volume pricing: first key $5-8, additional keys $3-5 each while you wait. We can color-code keys with rubber caps (great for landlords with multiple properties) or engrave labels—anything except "Do Not Duplicate" since that has no legal weight and we'll copy any key you own.
