The Nissan Path

Hello

there in finland is now -20 c. cold. yesterday works fine but on this morning its not recognice of Key, so it would not start a engine, also key lock mechanism would not turn at all.
if i try to push a central lock putton on i.key ..nothing not happened.. Car battery is a good enough.

Is that just a car how will not like cold weather ?

There is a battery in the chip that powers the cars key recognition. Maybe that went bad?

Do you have a 2nd key?
