Keyless remote, Keypad, or pass. side will not lock

[Parker Richards 2]

Hi all,

I have a 2001 Sport trac with keyless entry and keypad. The other day I went to lock my doors using the keypad and nothing happened, so then I tried my remote and again nothing happened. I then tried the drivers side lock/unlock button and it works fine, except the passenger side will unlock but not lock. My remote and keypad will unlock but not lock the doors. Any help would be much appreciated.

I inspected the rivets and the switches. I can hear a click under the dash. Could it be possible that is a relay that went bad? If so where would the relay be located?
