You could always tape/velcro/glue the key with the right rfid tag someplace close to the ignition. It's a major Jury rig, but it would work if nothing else, temporarily, if necessary.

I'm not sure if the system in your truck is like most, but I suspect it is. If you have 1 key, and you need a 2nd key made, the dealer has to program the thing to work. If you have 2 keys and you want to program a third to work, it's super easy and you could do it yourself. So, the general recommendation is if you have 1 key, to get 2 more keys. If you have 3, and you lose 1, then you can easily replace the third.

I did this on my Mazda and had my mother do it on her Jeep. We each got a car with 1 key. We bought 2 new keys. I'm not sure about my mom, but when I took the 2 new keys to the dealer, they charged me the standard fee to program the first key ($100) and programmed the second key for free.
