Reprogramming a new fob

[Xyleff]

someone(not going say who) left purse with keys inside truck and someone decided to pop into truck the same night. Truck has been recovered but not the keys. Is it possible to have the other key fob i have in possession reprogrammed so the ones the POS stole can’t use what’s in their possession?

Yes, dealer can remove old fobs and add new ines.

Is it necessary to get new fobs or can the old fobs be reused to reprogram?

They can be if compatible.

That is a question for your dealer. Somewhere along the line, RAM used one-use FOBs, that is, they could only be married to a vehicle once. I don't know how true that is but the owner's manual for my 2022 states this as does the owner's manual for my 2015. I don't know if anyone has figured out how to reset the FOB's electronics to a v.i.r.g.i.n. (damn censorship) state.

Here is the verbiage from my 2022 owner's manual in the section titled "Programming And Requesting Additional Key Fobs".

NOTE:
Once a key fob is programmed to a vehicle, it
cannot be repurposed and reprogrammed to
another vehicle.
(what is meant by "another" vehicle)

Until you get an answer from your dealer, I wouldn't purchase any FOBs from Amazon, eBay, or other sources just yet because you don't know if it has ever been married to a vehicle.

The other question is, can one FOB be learned in addition the the FOB that is already learned? I recall on an older vehicle I had, the FOB relearn erased all FOBs and then had to relearn them one at a time.

It would be great if you would post back what you learned.

No need for new fobs unless you want extras, you reuse your old fobs. They would run the “erase all fobs” routine. That will remove all of the programmed fobs from the truck’s radio frequency hub (this doesn’t erase the fobs themselves). Then they would just need to re-program only the existing fobs that you want back to the truck. Any fobs not programmed back to the truck (lost, stolen) would be rendered useless.

OP, you might want to think about getting all the lock cylinders repinned/replaced, too, because someone has the key to the doors now.

Just spoke to dealer, they basically said what jimmy07 stated.
