How did you check the key and receiver to determine that both were ok?
Key was checked by local Renault dealer receiver changed over with another one from a clio that was working
So the key is being recognised by the system?
Put key in ignition turn to start tries to start but immobilizer light keeps flashing . after battery went flat and I charged it up car did start for about 30 seconds conked out immobilizer light flashing
Do you have a spare key you could try?
No only have one key. Is there a immobilizer bypass that I can purchase
