I know they got the wrong keyless pad initially and even struggled slightly with set up (Forscan) but here are the P/N s i ended up with. Part of the Ford part number is identical to the part # you called out above. Cost me $100 for the pad and about a hour labor.
Also the 2021 Ford accessory catalog shows the pad available for the E350.
I appreciate the details. I googled your part number and it appears to be the previous version of the keypad I have, which is why they share most of the part number. On the Amazon listing for your keypad there was a comment that the new version (my keypad) has 2 communication protocols and if it doesn't work with one, you need to switch it to the other. I found a PDF with the instructions to change the communication protocol on a Transit forum. It appears they also have issues with the newer version of the keypad. I attempted to make the change, but I'm not 100% confident I was able to make the correct change. My keypad responds differently than the instructions say it should.
So it's not a full solution, but it feels like a step in the right direction. I'll keep exploring and see what I can find.
Unfortunately, on the Transit forum there were hundreds of posts and most said that their Dealers were zero help. That echos my experiences where I can't even get basic help ordering parts from the dealer. I ordered brakes from one dealer online and after a week of no update I called and was told "not to order online because I don't know how to get the correct parts", a few minutes later I got an email that my order was canceled and would be refunded. So I tried another dealer and their parts department was unable to do anything with out a VIN. I told him I had a Quigley with a solid front axle and he said "That's not possible on a E series".
So I'm not going to rush out and give either of them any money at this point.
