Hey, I was wondering if anybody could help me find the p/n for the correct key fob for my 2003 Trailblazer EXT LT. Thanks for the help.

They are available on Amazon - I think I paid $13 three years ago. Lately I found an OEM keyfob at the local PYP. I reprogrammed the system to accept both the chinese copy and the GM keyfob. Both work equally well.
When you find one make sure that the buttons are identical in configuration to yours and it should be OK.

And the two different part numbers are just for the case with 1 or 2 on the back. Internally, they are identical.

Okay, thanks everyone for the quick replies. I have two key fobs for my trailblazer but they don’t work to well, you have to be within 10 feet for them to work. Also they both were the same part number and had the number two on the back, so I wasn’t sure if they were the correct ones or not. Thanks again!

Have you tried replacing the battery inside them? Or have they both always been that way since you've had them?
