Electric boot - what does the button above the reg plate do?

[Babu]

I have a 2010 Alphard with an electric boot. I can use the button on the roof or the button on the remote to open the boot. The boot has a rubber button where you would normally press to open it, but it doesn't do anything. What's it for? (I'm not talking about the button on the base of the door to close the door once it's opened which is to the left, I'm talking about the button just above the registration plate

It activates central locking, to lock all doors on car. 

The Handle unlocks just the boot, the small round button locks everything, so you don't need to go to the drivers door or press remote after unloading shipping and closing boot

Yes, and it's pretty much the same on all Toys'
