Yeah thats probably the best option, glue should have enough strength to get the key out.
Basically to quickly explain what im doing, you can see my wheel is turned (start of video) and then i engage steering lock (So im slamming on the left and right side), what you need to do is centerise (Which is slowly do like half way in) and your key should be free of any stiff lock from the steering lock.
Like i said though, if you get a picture on we can directly advise you of what you should do! then it'l be sorted in no time (Y)
