Remove programmed FOB from truck memory?

[ThePaintPirate]

So I've just programmed my second newer style fob to replace my two older style ones which I plan to get rid of. If I wanted to program a third newer style one and the truck has hit it's max of 4 fobs total, would I need to remove the old style fobs from the trucks memory before hand?

It says he has a 2017 which came with a different style fob. He is changing to the fob you both have:





I don't have an answer for the OPs question though. I can't remember for sure, but I'm thinking you have to delete all the keys and start over. .. it's not possible to delete individual keys.
