Ignition

Hello friends, I turned on the ignition of the car today. In the first half of the ignition, everything was normal in the ignition, the car did not work, the car did not work in the second attempt, it did not work the same way in the second try. When I turned off the ignition and tried again, this time it worked. Has anyone experienced anything like this and has any information about the problem? Do you need to show it to the service?

The immobilizer may not have read it. I have c3 and there is no problem when it is running, but when it is stopped, for example, I turn it once and the contact turns completely. that is, there is a very boneless structure, it rotates in two stages when starting, but the vehicle turns off the ignition when stopping.... Is this a problem?
