Hi all. I have a 2009 XF. I have 2 key fobs for it. One of the fobs works perfectly, will lock the car using the buttons on the fob and also allows me to lock and unlock using the keyless entry system. The second fob will not allow me to lock using the buttons, nor will it allow me to use the keyless entry system, however, it will allow me to start the car when I have the fob on me in the vehicle. I have put new batteries in it but still no good. 2he. I try to use the keyless locking system using this fob I get two audible beeps. Can anyone help please? Thanks
