2004 Tahoe Keyless fobs are mixed up

When I use the keyless FOB marked 1, my car says it is for Driver 1 and when I use the fob marked 2 the car says it is driver 1. When I push the driver 1 button, my car says it is driver 1 and when I push the driver 2 button the car says it is driver 2.

It looks like the fobs are sending the wrong signal? This just started.

Any suggestions?

Try reprogramming them. The first remote programmed is recognized by the system as memory 1. The 2nd programmed will be recognized as memory 2.
