Ignition key stuck, won't key off or release key - fix - Vauxhall / Opel Astra Auto

Описание: Car would not let the ignition key fully turn off, or release the key from the ignition barrel.
On a 2016 Vauxhall Open Astra.
Key released by removing a the connector from the ignition barrel solenoid that is locking the key in.
Video shows how to remove this connector to release key.
Cause of fault on my car (I think) is the microswitch in the gear selector that detects the shifter is in 'Park' is intermittent. this micro switch can not be replaced, so work around is needed by disconnecting the locking solenoid in the ignition barrel.
Any automatic car with this same issue might be resolved with this fix.
