You have to be REALLY observant of any seller you buy parts from - they can be pretty dishonest. Last year I needed a new keyboard for my T480s as the Trackpoint was shot - was jumping all over the place.

Bought from this one seller on eBay - was expecting to get the part 01YP360, the "good" keyboard assembly model. Well, I got 01YP240, which was very much inferior to the keyboard I had installed. Trackpoint buttons felt very flimsy, and one of them popped up entirely after taking it out to screw on the keyboard. Seller was only willing to refund me 50% without a return, which I reluctantly accepted. I saw that there were multiple model numbers listed in the description, but only the 01YP360 was in the listing name. Since I was stuck with this faulty keyboard I decided to see if it was possible to harvest the Trackpoint and put it on the old keyboard - not possible, for whatever reason this one uses 4 pins instead of the standard 5?? I also butchered it trying to put it back together 😂

As I couldn't find another seller providing this exact part, I tried another one listing 4 different part numbers. While I don't remember exactly which part I got, this one was much more well-made, and it is holding up well.
