This is going to sound extremely daft, because right now I feel daft.

 

I have the 5 button key style for the 10 plate Vellfire. It has the Start/Stop button as well.

 

You can pull the key out from inside the key fob itself as well.

 

I cannot for the life of me see an ignition slot for the key around the steering wheel.

 

Just curious if I ever lost the fob part and only had the key, would the car still start with the button?

 

On a separate note, say I want to sit in my car and put the windows down, or turn on the radio, I can't seem to do this unless I turn my engine on, is this the normal way? 

 

Would prefer if I could at least put my windows down without having to turn over the engine. 

Ok ignore my question about the windows, turns out I can press the start/stop button without the foot on the brake pedal and it allows electrics and radio to function without the engine turning over.

 

If anyone has any advice on the ignition situation with a key would be much appreciated.

The immobiliser transponder is part of the remote. It is "impossible" to start the vehicle without the remote part.
The key only operates the mechanical door lock encase of flat battery etc.

The steering lock mechanism is entirely electronic, there is no mechanical key override functionality.

Thanks @threepot at least now I know the situation with it

Also, if your battery on fob dies, the fob is able to still work if you touch it to the start button, like wireless charging
