Stolen key and fob

[stevevaus]

Tahoe was burglarized last night. Stole key and fob. I will get it rekeyed BUT it also needs to be reprogrammed so that the stolen fob won't open it. Is that possible to do yourself without going to a dealer?

To be clear, I know I can reprogram my fob but the truck itself needs to be reprogramed ASAP

Thanks for any help.
