Lock button not working on 1 of my Key Fobs

[ScottyDontNZ 7]

We have 2 fobs, 1 works completely fine and the other won't lock the car but opens the boot and unlocks fine. 

It was the first time using the fob today and my wife reports that when she pressed the lock button the car would make a noise as if it were trying to lock. I have now tested it myself and I don't hear any noise at all now. 

Car model is 2007 525i and there is no model listed on the fob.
