Key fob not working to unlock doors,so had to unlock car manually.
Car is supposed to be immobilised, but on turning on ignition it started ok.
Is it safe to drive with the immobiliser warning light still flashing on the dashboard, until l can get it fixed, as, only have one key.
Thanks.

take the dashboard apart then take out the warning light bulb you should not have any more problems .
l am a mechanic for renault we are always doing this.

You bought French, pay the price!!

As far as l know it is not possible to disconnect the immobiliser. The immobiliser & alarm r de activated when u unlock the car with the 'plip' button on the key. If the electronic bit of the key goes wrong u cannot start the car. If the 'plip' receiver or ecu develop a fault u cannot start the car. The immobiliser system seems to be built into the electronics of the car. The key has to be programmed to the car in order to work & Renault charge a fortune for this (approx £140 to supply & program new key) l would recommend looking for an independent 'key programming' specialist who could help. l would ignore all the people on the net who claim it is possible to program a used key yourself - l have been down that road with my own 96 Megane coupe - l have spent hours & tried a total of four different keys (all infra red keys same as original) to no avail. Renault can provide u with a four digit code which u can put in to disarm the alarm/immobiliser as a temporary measure but this only works for a limited time according to Renault (they can not tell me how long though) & is a pain to put the code in every time u start up. Hopefully mine will be sorted this week as Renault have ordered me a new key under warranty as the old one that packed up was less than a year old (just). l am glad the previous owner of my car kept the receipt for this :-) Good Luck!!!!
