• 🔑 Two Keys Included - 549-00110A ignition switch comes with 2 matching keys. The lock cylinder and key set are direct replacement for Daewoo Doosan excavators. Keep one key on your equipment key ring and store the spare in the tool box on your DH220-2. A lost key requires complete switch replacement.
• 📋 Part Number Verification - 2549-1152 ignition switch replaces for Daewoo Doosan numbers 549-00110A and 2549-1152. The ignition switch with 2 keys is original equipment on DH-5 and DH-7 series excavators. Verify your old switch matches one of these numbers before ordering this 549-00110A replacement.
• 🚜 For Daewoo Doosan Excavator Compatibility - 549-00110A ignition switch fits for Daewoo Doosan DH220-2, DH220-3, DH220-5, DH55-5, DH130-5, DH60-7, DH80-7, and DH150-7 excavators. The key switch mounts on the control panel. Compatible with both Dash-5 and Dash-7 series models.

A failed 549-00110A switch on your DH220-5 causes no-start, engine shutdown while running, or dead electrical system.
• 🔧 Installation Note - Installing 549-00110A ignition switch requires basic electrical knowledge. Disconnect battery before working for Daewoo DH60-7. Label wires before disconnecting from old switch. Transfer wires to same terminals on new 2549-1152 switch. Mount switch with included hardware.
