What do you have? Year, options and such. Did you replace the switch or the lock cylinder?

I rec starting with the basics for electrical problems.
Do you have a multimeter/DVOM/probe tester? You will need a good tester and some awareness on how to use it.
I'd first check battery voltage at the battery terminals, then check for that same voltage at the grounding points.
Battery voltage should be at least 12.5v, with 12.7 even better.
Check battery cables are flexible. I would check the cables for resistance, or replace them if they looked bad. Point is to know that your basic power supply is good before troubleshooting systems.
Any mods to the truck like external lighting, winch, stereo, tow connectors/brakes?
