My 2016 Foton Tunland is not recognising the key

It sounds very much like the vehicle thinks it has an issue with the key. Modern ignition keys send a coded, electronic message to the car’s computer telling it’s okay to start the engine. Without this communication, it’s possible the car won’t start. The background to this is to prevent the car being hotwired and stolen without the key.

The problem could be as simple as a flat battery on the ignition key. Again, a flat battery means no message to the computer and no start. If the battery is not the problem, then you need to dig deeper to see if the car’s body computer is controlling the security system correctly.
