Hello Thanks for any advice in advance Car is a Nissan Micra 1.0 litre 1999 on an S reg used as a cheap runabout. I got in the car last Friday and tried to start the car and the car started for 2 seconds then stopped with the check engine light flashing on the dash which after digging round the internet discovered it was a NATS problem. After repeated retries I gave up and tried the other key with the same problem. I called my Auto-Electrician guy who took a look and promptly discovered the immobiliser had lost its codes for the keys. He reprogrammed it with the key codes and we were back in business. The electrician also checked all fuses and relays and said they were sound and couldn=92t see a problem with rusty fuses that sometimes causes problems with the NATS according to him He was unsure as to why the immobiliser lost the key codes and I=92m a bit wary now and question if it could happen again. Fortunately this time it was on the driveway but what about if it happens again! Can anyone explain why this would have happened ? The only thing that has been done recently is the battery was changed in March but this is 3 monthes ago surely that cant have affected it ???
Hope someone can shed light on this or has come across something like this before?
