Unlimited Key Mode

WARNING: This page is about a different variant/trim than selected.

PATS  contains a feature called unlimited key mode and uses the PID UNL_KEY_MODE. This feature allows a customer to program more than 8 keys to their vehicle if they request it. Each vehicle in unlimited key mode is set up with a special unlimited transponder security key code. This allows all the customer vehicles to share the same mechanically cut keys, but no other keys from outside can be used to operate the vehicles. When in the unlimited key mode, the N_KEYCODE PID always reads 2, no matter how many keys are programmed to the vehicle (after the first 2 keys have been programmed). For an individual customer, any randomly selected security key that has been previously mechanically cut and electronically programmed to the vehicle is acceptable. Refer to SPARE KEY PROGRAMMING - UNLIMITED KEY MODE  in this service information.
