I suppose this can be fixed assuming the chip in the key is still good...

Wifey ran out for some groceries.
Upon opening the door, alarm sounded....keyfob works but no crank.
Headed out there with our bad key (it starts car but remote funtions dead), and it cranks the car just fine.

Figuered maybe the EWS might reset itself bearing a good start. Headed home together and after a couple tried, the good key *that has working remote*, just won't turnover the car...

I suppose buying a new key is FINALLY in order.....as it's probably going to be cheaper than tech time, if the key can be synched back to the EWS...

I held off buying a replacement as the X is sorta on a 1 year'ish countdown to being sold.
