The Doosan Daewoo D300 Master Key – The Heavy Excavator Essential

Got a Daewoo or Doosan excavator that needs to get back to work? If your key is stamped D300, you've found the perfect replacement. This key is the industry standard for the legendary Solar series and modern DX excavators. It's a rugged, all-metal key designed to withstand the brutal vibrations and dust of a civil construction site.

Why You Need This (Aside from Avoiding a Stalled Site)

• Precision OEM Fit: Specifically cut for the D300 ignition profile found in Doosan, Daewoo, and Terex heavy machinery.
• Broad Compatibility: One key starts a massive range of excavators, from 14-tonners up to the massive 50-ton beasts.
• Durable Construction: High-quality alloy that won't bend or snap when you're turning over a cold diesel engine on a winter morning.

Compatible Equipment

The D300 key is a confirmed fit for a wide range of heavy equipment, including:

• Doosan/Daewoo DX Series: DX140, DX210, DX225, DX300, DX340, DX420, DX480, DX520.
• Daewoo Solar Series: Solar 140LC-V, 175LC-V, 210W-V, 225LC-V, 300LC-V, 340LC-V, 420LC-V.
• Terex Excavators: Various heavy Terex models (often manufactured by Daewoo).
• Other Machinery: Fits selected Bobcat E-series excavators that share the Doosan platform.

• Stamp Code: D300
