This is off topic, but I was in a junkyard trying to get an antenna off an w123, and the owner tried to pry it up. He couldn't, so he got a forklift. He had to lift the car about 20ft in the air for the locked trunk to pop open. Even then, the hinges wouldn't come off Take it to nearest dealer. They should jus replace the cylinder. I wouldn't mess with it cuz then u'll end up spending more $$$
