Functioning perfectly at Blaupunkt CAR 300 - fast delivery

I wanted to expand the factory radio (Blaupunkt, Car300) in my old Astra. I've only the 4 Allen Schraubem unscrewed and then the release button with 4 long nails trying to solve. Did not work really.
On Monday evening I then ordered this Entriegelungschlüssel and on Thursday morning they were there. Key reingesteckt the radio. Both keys pressed slightly outwards - as I slipped the radio also answer already. I was from a "cheap tool" never surprised so positively. Perfect Deal!
