Hello guys, i'm new to this forum and been reading carefully all your posts on this subject. There seems to be quite a bit of confusion here. I have the original service/technical manual cd´s from Renault and it cover´s all cars till 2004. The manual states that the procedures above and found wildly on the net is for re-sinchronising the remotes only! Is when the frequency is alredy programed in the car and the remote goes out off sync with it. It is NOT for peogramming a new remote frequency in to the car. The ONLY way to do it is with the diagnostic computer at Renault or a dealer that has one. You can onle program 2 remotes at once. As for programing the car to acept a new key (transponder chip) it can ONLY be done on the diagnostic computer too, and you can program up to 4 keys, witch is kind of dumb IMHO as if you shoud be alowed to program 4 remotes as well. So that saied you can buy a key on e-bay (will save you about £90) but you still have to spend some to get the car programmed to the key.
Resuming all of this, it is the CAR that´s programed to acept a new key (transponder signal), so the car doesn´t care if the key is new or used. What the dealer does is conect the immobilyser to the diagnostic computer and put the immob. in lerning mode to clear all the codes programed into it and then it is told to acept the new code from the key. If you have another key you have to bring it too as the immo.'s "memory" is cleared and then programed to acept the codes again.

I agree with what you mentioned. I bought a 2nd key off ebay , but when I turned up at the renault garage to get it learned into the megane they tell me its not possible. However I previously spoke direct to a coding engineer and say it is possible. Im suspecious and confused, but I will get back to an engineer and question him again

hi there unfortunatly you will be unable to use the megane card on your laguna so tell the guy on ebay to send you your money back! there are a few rules and reasons to follow when dealing with renault keys or cards,
make sure it is a virgin card
key because once programed to a car it will only work on that car.
use only the correct card for your car i.e laguna handsfree or not, 2 or 3 buttons.
other cards cannot be interchanged this it due to the fact that they signal at different levels of mhz's
ebay is a real no no for buying keys, in the long run itd be cheaper to buy new!
good luck bigshow
