I want to tell u the full story about the car
I washed the motor of the car and after getting out from the wash shop it appears a STOP sign so I stopped then the car is stopped and the engine didn't want to start up. the electrician told me that the BSI or UCH ,i don't remember, is broke down and we should replace it as it is replaced the engine is started again but the the back lights was off completely . we went to buy another plugs for the electricity in the board next to the motor.the key didn't want to work again and always shows the key sign i have told u about. that's all story I wish u can understand the point now.
