None of the remotes shown are 2 button type and for Focus, your method is the correct procedure for programming. You could have a fault with the control unit but give the folowing a try. They are different methods.
Instead of the 4 times in 6 seconds, try :
a) 4 times within 3 seconds,
b) 5 times within 10 seconds,
c) 8 times within 10 seconds.
The time limit is important but do not rush. You might need to repeat the procedure more than once. During the turning on and off, you should hear the horn to indicate you are in programming mode.
