Motor ignition problems of a kia

Good afternoon to the MDM community, I have a problem and I require your help, I have a Kia Carens II year 2007, which does not want to turn on, arrive at the house without any problem and now you do not want to turn on the engine, the engine seems or sounds as if it lacked compression. But as I commented not to fail at all, nor did it turn on the service light either suddenly. Do you have an idea what can be? Thank you very much in advance.
