If the car was running pre the broken key then why should anything else but mismatching key be the problem ?....
Several pitfalls when starting to mess with this system
On a year 2000 the Immobiliser is handled by the BII unit in the floor along with most of the car input and output controls. The BII is configurated for your car only on both immobiliser, engine type and more. You cannot swap from another vehicle unless you swap everything (instrument panel, BII, keys and injection computer).
BII unit recieves the data from chip inside key via an aerial around ignition lock. If BII accepts the key, it sends a code to the injection computer unlocking it so you can start.
Also, Remote reciever is located in the instrumentpanel and key recognition is programmed in both the instrument panel and BII unit in the floor - this means no other than your original key or a replacement key from Renault will work on the remote control either.
Only way (that i can share anyhow) you can bypass the immobiliser is if you have the 4 digit security code, then entering it each time you are starting the car.
You will never get it started normally with the wrong key!
