Ignition not turning off

[Hytsep]

My wife has an 2015 Audi A1. 
Got the call last night when she got to work that she’s took the key out but radio and dashboard stays on. 
I got to it and confirmed. 
 

- Parked vehicle. Turn key, engine turns off and blower stops. 
- removing the key, radio stays on and sterling lock does not engage, dashboard also stays lit up. 
- opening door has no change. 
 

What I’ve done so far: sprayed some silicone lubricant in to the barrel to see if it’s a sticking mechanism. 
I found that a few taps to the barrel and fast inserting and removal of the key will make a latch or mechanism in the barrel release. 
 

Wondering if there was any known issues or things I could look for in replacing it?

Just to update. 
appears lubrication with the spray has solved this.
