From what I have heard about the key card on Lagunas/Megans etc. is that everytime you put them into the ignition slot they are recoded through the card reader from the ECU (which controls the whole thing, electronically speaking anyway). as such if you battery has gone flat etc. hopefully you shouldn't have a problem with it needing to be recoded manually.

Let us know how you get on.
