Accessing to Honda key/immobilizer codes require the employee’s personal information to be entered in order to maintain accountability and ensure personal responsibility. To calculate PCM access codes for Honda vehicles (Honda Insight, Civic, Accord, Prelude, S2000, CR-V, Odyssey, Pilot, Element, Ridgeline, Fit and others…) you need to know last 5 digits of VIN (Vehicle Identification Number).

These codes are required for access security procedures with HDS (Honda Diagnostic System) and other OEM equipment
