Went to start truck (43,000 miles) with key fob, did not start. Started with key but check engine light stayed on. Drove to work (70 miles total) with no problem. Check engine light still on. Any ideas? Going to put a code reader on when it warms up.

Welcome to the site.

 

Thinking your main question is concerning your CEL.

Your key fob problem is a safety feature caused by the CEL being on.

 

How is the truck running, is the CEL steady, or flashing?

Steady...

Have you had any strange electrical issues before it came on?

Will update when fixed. 
Cool deal. Drive it for a while 10+ on/off cycles to insure the code Doesn't pop up again. When a vac leak is present theres a good bit of possible leaks. Hoses leading back to evap canister and solenoid the charcoal canister itself and oddly fitting at the fuel pump or rotted fuel pump. Also a solenoid (forget the name atm) next to the throttle body with evap hose connected. Its a run around but easily solved via smoke test[which i suggest to save you cost and down time] that you'd need to specifically ask for should you have a vac leak. Cheers to your resolve![emoji482]

Awesome! I wasn't aware of one above the tank. Glad they are taking care of it for you!
