Last week, I bought the Mini ND900 and used it copy chip 46 for Nissan March 2015 Successful! I share my experience here. You can try it by yourself.
How I use Mini ND900 copied chip 46 for my Nissan March 2015?
First, I put the original ID46 transponder key into the slot of Mini ND900. After that it shows Identifying Models. (note: Don’t move the key)
Secondly, I click “COPY”. It show "Please insert the original key",
Click "ok" the Mini ND900 screen will appear success.
At last, I put the copied ID46 chip into a new transponder key, and I use the new key to turn ignition on, it works! Now I own 2 transponder keys for my Nissan March 2015.
