dunno about the Clio but on the Laguna you could key in the code instead of using the remote. IIRC you had to put your foot right down on the accelerator, then put the first digit of the code in release your foot then back down on the accelerator next digit of the four number code, etc until it was complete. Once it was complete the red light would flash and off you go, the car will then start. to ky in the number you used the anonymous looking switch on the end of one of the stalks. Does your manual tell you anything about it at all?
