Keyless locking and alarm setting problem

My 2000 Rodeo just started this today.:banghead:

I have a problem with my remote locking and alarm setting. The lock buttons on the door work intermentantly. When I can lock it from the door buttons, I can set the alarm with the fob. I cannot lock the doors or set the alarm with the fob. I can unlock from the fob no problem. I hear the relay click on the drivers side door when I push the lock button, and unlock it from the fob. Is there seperate sensors fro the lock and unlock from the fob. Any suggestions.

Thanks in advance for any help

Might seem obvious... but replace the battery in the fob... worked for me!

I changed the battery in both fobs. No luck. Thanks for trying.......
