Can you cycle the central locking using the buttons on the fob?

Would a 2007 model have two batteries? It probably has the main battery that powers the starter plus an auxiliary battery that handles the electronics.

I think that the auxiliary batteries came in when the Stop-Start did.
I was wondering if the key needs resetting to the car EIS?
