Keys repeat occasionally on Elk

Every once in a while, when I go to disarm the system, a key press will record double presses when the number is only pressed once.

The keypad is the M1KP2 and the only othe thing connected is the GE compatible wireless accessory.

Has anyone else seen this?

How old is the keypad?

6-months old

Do you have duplicate numbers in your code?
 
I haven't seen this myself, but I have had instances where I went too fast for keypads to register or they registered a duplicate number. * to clear and all is OK and I really haven't paid too much attention.
