Ok, got to the beeps and blinking. I have the correct fob, all numbers match. I understand the process I believe; for 313 I click "lock lock lock", "unlock" ,"lock" "unlock" "lock lock lock" "unlock"
After typing my number the audible and blinking lights CONTINUE but no new sounds. Am I stupid? I just hate this stupid key! It's so obtrusive and hurts in my pocket at work all day!
