Lost keys for your Komatsu? Don't worry, Plant Keys has you covered.


NOTE: This is the master key for Komatsu models which was the main key used to both unlock and start machines. Recently this key has been superseded and only unlocks the door but won't start the ignition. Year models around 2021 onwards use a different key for the ignition. Please check your key prior.


This key suits a Komatsu 787 excavator and operates the following machines:
  • Komatsu Excavators
  • Komatsu Graders
  • Komatsu Dozers
  • Komatsu Rollers
  • Komatsu Skidsteers
  • Komatsu Backhoes


We also have key for Kobelco, Hitachi, Kubota, Komatsu, & many more!
