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). Accessing to Honda key/immobilizer codes require the employee’s personal information to be entered in order to maintain accountability and ensure personal responsibility.
