Sorry to start another NATS thread all! Have had a read of everything I could find but no one seems to have had this situation arise.

So....when i purchased the wagon it came with two keys. One an original NATS key and one a knock off with chip. The knock off key has always worked until recently. The NATS chip has fallen out of the original key. Then the knock off worked perfectly for months until recently when it no longer works in the ignition barrel so back to the NATS key and the engine management light thingo flashing. Thankfully it still runs on lpg but can't change to petrol because of the factory immobliser. What I need to know is if a local locksmith can get the code off the knock off key to reprogram a clone? OR am i forced to go to Nissan because I don't have the orginal chip at all.

All help appreciated on this one.
