2011 RAM: Key fob programming... only eight keys can be made?

I recently ordered two new key fobs, as my inherited 2011 RAM Laramie Longhorn's latest of four fob's lock and unlock buttons have bitten the dust (definitely a fob problem, not a receiver issue in the truck itself).

So far as I know, four keys have been programmed so far for this truck. The original two fobs, and then the next two replacement fobs that were programmed by Chrysler Dodge dealership six years ago. Each fob seems to last about three years, and then tanks.
I ordered an OEM fob from Keyless Canada, and also a Pro Key Box fob programmer along with an aftermarket fob compatible with the truck's ignition system. These products have arrived. While reading the instructions before using the Pro Key Box programming tool to program the two new fobs, I read the following;

"If the programmer beeps eight times after being inserted into the OBD port and will not pair the new key, it indicates that the maximum number of keys have been paired. Your vehicle only allows 8 keys to be paired."

Okay, what's up with this? I haven't actually tried to program the new keys as I want to be sure what I'm getting in to. I realize that *if* only four keys have been programmed so far, I have quite a few years left of driving, about twelve years, with any fobs that I program, but.... I can't ask the original owner, my father, if he programmed any others. He has passed away. This is how the truck has come to be mine. So if he did program other fobs, and/or I lose a fob or two, then what?

Can someone fill me in with what they know about this issue? Is there a way that you've found to get past this limitation of an eight fob programming maximum, and if so, what needs to be done? I am trying to avoid the dealership selling and programming the fobs, as they want $450 CDN per fob, while the Pro Key Box was only $125 CDN, and OEM fobs with tax are only $85

Thanks in advance for any insight that you can lend.

You can delete the old key pairs with AlfaOBD or the dealer can do it.

If you delete old key pairs will it delete all keys? Including a fob that is currently dead and only works when pressing the start button with fob?

My Og fob but the dust, only works when pressing the start button WITH the actual fob. I guess it had 3 fobs already programmed (I only had 2 but lost one) And I’ve had 4 unsuccessful fob programming’s, so now I’m at 7 total. Don’t want to try another fob that ends up not working and then be screwed.

My new fobs programmed fine then quit after first start up and drive just like outlined Here
