Renault Twingo built in 1995

Hello, I have a problem and it would be nice if someone could help me. My Twingo doesn’t start this morning. My friend thinks it’s the immobilizer. Now I’ve read everywhere how to turn it off and everywhere the central locking is mentioned. But I don’t have a central locking but still have to open the doors with the key. Now my question. Does my car actually have a throttle lock? If so, what can I do to deak this? LG C. Engel
