You simply cannot. You have to be a dealer, then the RC company will send you the code to remove the lock. Sorry.

Is there a solution to the above problem?

sounds like you need a new motor. 2 flashes indicates left motor.

Dear dalton....Patrick here
I believe this may be impossible with normal use. Alarge magnictic force would do this. My RC-8000 had odd ball problems that it was sharing with my 5803. Once I fixed the JOY STICK all other problems went away. If it has programing issues, then Denon will have to deal with it. Use there Portland Ore. Service Center and Pay the money.
