Have bought a new unit as nothing is shifting the old lock. The breakers unit is crazily priced a new one is £50
Videos on the internet indicate that there is no need to reprogram the key to the immobiliser.
Thanks all for the help.
I did find a US video that says they fail & they have a local part that is turn for on & avoids the push in bit which apparently what causes failure.
Will post photos as I do it.
