2001 toyota loser cruiser ( estima )

Remote/key fob stopped working so replaced battery and still no success. Did google search and found the reprogramming instructions which i performed and it seemed it didnt work. A few hours later my wife went out and without thinking hit the button and it was working. It worked fine for 2 days and then i opened the boot door and it hasnt worked since. Tryed reprogramming with no success.

Its a single button remote and the instructions all refer to 2 button remotes as one of the steps is to push both buttons similtameously (sp?) But as above it worked regardless.

Any ideas?
