98 4wd 4door blazer. key fobs quit working. put new battery in no luck. fuse infuse panal side of dash ok.key fob is good. what next? help please

 

Assuming you have two fobs and neither works, verify the receiver is still plugged in. It's attached to the plastic panEl under the driver side dash very close to the parking brake. If all looks good try programming the fob to the car again.
