Fabia Audio-Dance-Stuck in SAFE mode, bypass 09

My nearly 5 year old Fabia has the Dance audio system- factory fitted, which is a very sweet sounding system.Like it. I had a malfunction of the auto door locking system, where the door open warning lights came on while driving, in-spite of all doors being securely locked.This also caused the roof lamps to come on while driving. The problem also occurred while the vehicle was parked and at standstill. I analysed the probable cause to be excessive exposure to the monsoons, when the car was parked in pouring rains for long hours on consecutive days. It could also have due to the car wash guy spraying the doors vigorously during the wash.(The problem of "door open warning" has since disappeared post monsoons.) On advice from the service centre, I disconnected the battery to avoid a drain out. This resulted in the audio system being locked in the safe mode, when I re connected the battery. Also re set were the clock, and trip meters. On switching the audio the following message is displayed-"SAFE-BYPASS 09" The system does have a security code, which the system prompts at random. On entering the code, the system accepts the code and plays, only to go into SAFE mode the next time. The prompting for code does not happen every time. For the past few weeks I have been stuck with the SAFE mode, unable to enter the code and play the system.
