It is the basic journey key. Sorry if I sound lame, but I don't push a button to start. I just put the fob in and turn. And it starts. Last night I locked it and now today...nothing. Cant lock or unlock it with fob. I want to drive to go get a battery. But I don't want the alarm to sound when I used the metal key and...with the fob not working..not be able to turn the alarm off. I hope that makes sense.
