just fixed mine now,the radio stayed on and door beep was going off. I took the barrel out and where the plunger,in the barrels sits,there was dirt that collects on the key blade and cleaned it out and works find now, I put it down to the plunger not locating fully when the key is taken out. if you look at the housing, and if you look down the housing you will see another plunger,this pushes the plunger in the barrel up,when the key is taken out
