I have searched the forum and found similar posts but haven't found an answer specific to my car and key type. Can anyone point this newby in the right direction please. Can any matching Renault Clio, Megane or Laguna 'Scrapyard' key sort this?
I'm travelling abroad soon so don't want to rely on one key only!!
Ok so nobody knew anything... well now i do!! Don't buy a secondhand single button Radio frequency key as it won't work
for 2 reasons! A) The keys are individually coded to the cars central locking, unless you have the correct individually coded key for your car you CANNOT follow the proceedures posted elsewhere for re-synching the key to your car. A local scrap dealer charged me £23.50 for a key just so i could find this info out....
B) The key also has a coded transponder that deactivates the immobiliser. It is a close range device that only works when the key is in the ignition. In a scrapyard key this will have the wrong code for your car and won't work.
So.... what do you do? Well if you have lost the keys and don't have the codes in the servicing manual to order a new one from renault....... you are seriously stuffed!! New keys, injection module and immobiliser are all probably required and are likely to cost more than the car is worth unless you can source the correct ones from scrap (all from the same car so they match don't ask me how as this would be a speciallist job and i'm not a specialist!!)
If you have the cars original servicing manual then the key number and code should be written in it. A new key can be ordered from Renault using the codes (10 days wait plus £150 ouch!!) the same info should be inside the original key if you have it and it's bust. If you don't have the service document check the cars history, if it has been owned by a lease company or similar they are likely to still have records of the car which just might stretch to the key numbers if you are lucky!! Anyhow i just need a spare key incase my original is lost i have the codes and a working key so could go to Renault ....but don't want to spend £150. The solution is found through a local locksmith. He has a transponder reader / programming device and can cut a key from the existing one. This gives me entry to the car via the physical key, the transponder will switch off the imobiliser and i can drive off. Ok so it doesn't have the central locking working via the plip but i now have a 'spare' key to get me out of trouble! If the main key is ever lost i can bite the bullet and buy an original from the dealers. The local locksmith wants £21 for his services in cutting a key and programming up a transponder which is a lot more affordable.
I hope this saves someone else the hassle and time that i have gone through to find this out. Chris
