Kangoo 99 1.4l does not start after 5 days of service life

I don’t know what to do anymore. Short to the problem: Renault Kangoo just bought it the other day, wanted to rebuild it to transport scooters in it. Vehicle was supposedly running smoothly. Since the day before yesterday it no longer starts. Both keys tried out. Nix. Red lock lamp also goes off, shortly after switching on the ignition. So no mistake. My brother drives nen Twingo. After a tip from the forum I changed the OT-Geber, so from the Twingo into my Kangoo and around Nix. Twingo runs with both OT-donors and the Kangoo with none. Of course also cleaned plugs. Start pilot during the start process also did not bring any success. Also press the CRASH switch, did not bring anything. Bridging of course also not. Also checked all fuses… I unscrewed the spark plug on the first cylinder, plugged it in and held it against the cylinder. Then started, But he DOESN’T TELL!!! I don’t know if he gets fuel, but without ignition it works anyway. Does anyone have a COUNCIL??? Thank you
