Single button remote Key programming

Hi All Am trying to work out how to program a Single side button Original key!
I have found the threads on here but they seem to be for twin button keys!

I have gotten to the programming stage procedure where the locks cycle
key in
key out
lock>unlock 5 times
close door
open door
lock>unlock 5 times
key in > ignition on> ignition off > remove key
Cycles 3 times

Then??
Thanks
