key less remote and home links isn't working

check the battery in the key fob first

That was the first thing I checked. The home links isn't working, either, and it doesn't run off of batteries. What should I check next?

i am taking it that all fuses have been checked underhood and in passenger compt. here is a diagram of fuses to check. Also check #10 in passenger and 47 underhood. If these are all good then a computer will need to be hooked up to see if transmitter or multiplex unit is bad or a bad wire.

also check #13 fuse on passenger side fuse box.

All fuses look to be good. Guess I will take it to a mechanic to hook up to the computer, thanks.
