Hi tim, had the same issue not long after picking up my 370.... My first thought was oh s#Â¥* after reading about the steering lock issue, as above check on here for up to which vin numbers are affected..I think the affected cars are up to around mid 2010.. Luckily mine turned out to be batteries needed replacing in the fobs very cheap and easy fix, there is a how to thread on here somewhere
I would try changing fob batteries first and take it from there good luck
