Remote and my keypad remote both stopped working as of today

Yesterday my remote and my keypad remote were both working perfectly. Today neither are working. The wall switch opens and closes the garage door, but the remote and keyless pad don't. What should I do?

CHECK TO SEE IF THE LED ON THE WALL BUTTON IS BLINKING - IF IT IS SOMEONE HAS PUSHED THE VACATION LOCK BUTTON.
PRESS THE LOCK BUTTON TO MAKE THE LED STAY CONSTANT AND IT IS FIXED.
HOPE THIS HELPS
