HONDA claims the CR-V's keyless entry system now incorporates a copy protection system that makes cloning the keyless entry code virtually impossible. This is achieved through the use of a random code that changes each time you lock or unlock the vehicle. The ignition key is cut to a new "wave key" design, making it difficult to copy. The key fob opens and locks all doors and a separate button opens the tailgate window. The fuel filler flap is opened via a remote lever mounted low on the driver's side kick panel.
