I can only speak of my situation (it may differ for you), but my car's getting a new set of keycards (3 in total), plus they will be programmed to the ecu (which I would presume will get a 'new' coding to render the old ones obsolete. The emergency lock on the passenger door (under the cover at the handle) is also getting replaced and will match up with the emergency keys in the new keycards. This will mean that no opportunist will be able to open the car or start it up using the keycard or key that was lost.

All in all, I would reckon that this is costing a good few hundred (that's me had a week's car hire so far, and the car's still away). So the final bill may be closer to a grand - but not for me.


This job should never be complete - the day I think I've done it all, is the day I resign.

Just had 3 quotes from Renault as I require a spare.
Keycard costs 64.02 + Vat which is obtained from Renault (France) presumably with my cars info programmed in. The vehicle then must be taken to a local Renault dealer who will programme it to the ECU at a cost of 40 (cheapest)
What a racket.

I remember reading somewhere that new codes will be programmed so the old one would not work anymore.
Based on VelSatisfied's situation I suspect not!
As I understand it, the coding works two ways:
1) The card is programmed to match the serial number in the car's various computers.
2) The car's ECU is programmed to recognise the unique and separate serial number in the card.

The first point is the reason why second hand cards are useless. The cards can only ever be programmed with one computer system's serial number - it's a one-shot programming system.

The second point can effectively be used to disable lost/stolen cards. The car will only recognise the cards that were present at the most recent programming. Any cards that were not taught to the car on that occasion will no longer be recognised, even if the car had been programmed to accept them in the past.

So your lost or stolen card should be doubly useless now. It can't be programmed for use on another car, and your car will be programmed not to recognise it when it's paired up with your new and existing keycards.
