Key fob/ service tire pressure monitor system

[Grant Hoyt]

Hello, my key fob stopped working and light comes on cluster service tire pressure monitor system as I was trying to get in to drive  tire pressure on dash reads lf--/rf-- and so on. I can't reset tire pressure location. Ignition on, park brake on, press hold lock unlock on fob. No horn sound. What can I do?? Thanks
