The guy lost their keys for the second time…and had already programmed a new key so when they found their old key it didn’t work anymore…the key is a n101 transponder is a philips 46.
I’ve done a couple of micra k12 and qashqai standard keys with xtool x100 pad2. Done a couple of each worked ok. Reads bcm number and gives old and new pin.
1) Switch ignition off and remove key
2) Insert the 1st key and switch on for 5sec, then switch ignition off and remove key
3) If you want to add more keys, repeat same procedure until complete
