If you have two old sentry keys and they still start the truck, you can program your own keys from the comfort of the driver's seat. The key programming instructions are on page 17 of the owner's manual.
I bought an extra blank sentry key on Ebay, took it to the local hardware store and had them cut it (they weren't too happy that I didn't pay their new key price, but they did it anyway saying "no guarantee") and then I programmed it myself using the instructions in the OM.
No lube required, if you have two working keys. (the fob buttons don't have to work, the key just needs to be able to start the engine)
