2008 XK Keyless Entry

Both my keys operate correctly on all buttons but the keyless entry doesn’t work. The keys both have brand new Panasonic batteries. The car will start with the key anywhere in the car.

I have the electrical guide and from that, I’m guessing the keyless entry is a separately programmable feature of the key. Can anyone confirm that this is the case? It may be that the PO got this disabled by the dealer but I like it and want to enable it. I have successfully programmed my XK8 keys with WDS version 118.5 but I’m not sure if this version works with X150. Does anyone know for sure?

Thanks for any info.
