help with car key
I know this probably comes up a lot, my wife's car battery died a few months back, she got it changed, but by doing so her key no longer works as a remote start or for the locks, and only works when brought directly up to the steering wheel, (2013 ford focus HB titanium). We don't have a spare key and i just got one today off amazon but i was trying to pair it using Forscan and it kept saying its not a compatible key even though i matched the number prior to buying it, is there anyway i can connect it to the immobilizer so the key gets registered?
