We now have a the full set of Smart back-up options, one to get inside and another to get started if the battery in the key fob dies. The Mercedes-Benz and Geeley joint venture is now focused on electric vehicles (EVs), namely the Smart 1, Smart 3, and Smart 5 line of crossover SUVs.
Unlike the Fortwo models, the 1, 3 and 5 are keyless start.
The Smart 5, however, makes no mention of using the more conventional key fob in any way to start the car if the battery inside the fob has died. Rather, the company describes using an NFC (Near Field Communication) key that is supplied with the vehicle, essentially a key card.
We feel that key cards are too easily misplaced and recommend trying to place the key fob on the charge pad to see it it will be recognized. This option is available in models from other manufacturers.
We may never see one in the States, but will certainly test this if we get the opportunity.
And remember that Bluetooth is disabled on many cell phones when the phone’s battery is weak. We don’t recommend counting on a phone for managing any model car.
