Spayed the blade with WD40 amd left it in the lock before twisting and then only twisting gradually it eventually turned without breaking, A neighbor told me  my alarm went off due to three foxes dancing on my bonnet and roof setting the alarm off and flattening the batteries, bloody foxes

In the past I used a very good independent workshop Basic service + MOT with the main service every 5 years had the car for 10 years no problem and that is the minimum you should be doing. I have no faith in my local main dealer so use an independent specialist who has many years experience with Subaru and does not work on other brands has all the correct fluids and spares. Not cheap but not as ecpencive as the main dealer. 

Try ChipsAway some of them do bigger jobs than just dents
