Nissan was forward thinking on their flagship the Nissan Leopard F31 back in 1986: it featured a keyless entry card! Earlier Glorias and Cedrics already featured pin-code like systems, but they keyless entry card is going way further than that!
This card has the size of a credit card and the thickness of a modern smartphone, but allows the wearer to open the doors and trunk without the use of a key!
The system was actually quite simple:
Two sensors operate this system: one in the driver side mirror and another in the rear bumper. Both sensors will unlock either the driver side door or the trunk separately from each other.The system was only available on the Ultima edition of the Nissan Leopard F31.
