Engine control unit with matching immobilizer and uncut key from a 2005 Honda Civic HX with automatic transmission. This set was tested in vehicle after programming and ran properly with no check engine light on. The case has some minor dents and wear from use, but no broken parts or corrosion. The connectors are in good condition with no damages. The circuit board has been inspected and no damage was found. This includes a pre-programmed used OEM immobilizer ring, and a new aftermarket uncut key. The pictures are of the actual items you will receive.
A new, programmed but uncut key is provided and will need to be cut to match your vehicle's ignition switch. No programming is required if the ECM is installed with the matching immobilizer ring and new key.
