Door locks
From the sound, you have electric door locks. If this is the case and the key will still lock the door, I'd let the dealer deal with it Fri. To answer the rest of your question, not you don't need the forked tool to remover the door panel, but it is easier. A screw driver will work. Just take the screws out of the inside door handle cup, then with a screw driver, start at a bottom corner and pry the cover out, when you can get a couple of fingers under the cover pull at the plastic fastners to remove. Your truck is new enough you should be able to re-use the fastners. What you don't want to do is break off the retainers that are moulded into the panel. Didn't check your location, but if it is cold, below 50 degrees F. the plastic will become brittle.

Just checked your location, think you better warm everything up before operating!
