I bought my 2007 Ford Focus used and it came with a single key that works in the door and the ignition. Only the driver's door has a keyhole. All the locks in the car are electric, I can unlock everything from the driver's door or the passenger's door. The car came with no key fob to unlock the doors remotely. Every car I've had since 2000 that had electric locks, had a key fob to unlock them remotely. Is it "a thing" for late model cars to have electric locks but no key fob? Is it just a matter of going to the dealership and getting a key fob? Or am I going to have to do something after market to make these locks work remotely?
