Start driving with keyless go with the emergency key?

My Rio is a 1.4 Spirit from 2014. This one has Keyless-Go and this morning the following happened to me: I went to the car at 5:00 a.m. because I had to go to work. I usually have the key in my work bag. When I pressed the unlock button on the door handle nothing happened. Look and no key in the bag. I then looked for the key but did not find it right away. No problem thought i ch me, I just take the second key. I am then with this to the car and still could not open my car, neither via Keyless nor by pressing the key key open. I then used the emergency key and opened my car with it. Door opened and first of all scared because the alarm went on. The start stop button pressed and nothing happened. Alarm system also made nice further noise. Since I unfortunately did not get any further with the second key I moved the With this key everything went back to normal. Now two questions ask me. 1: Is there no more old-fashioned ignition lock in which I can start the car with the emergency key? 2: Why could I not unlock my car with the second key?
