(FYI) Helpful Hints: 

To unlock a Dynamic Shark joystick, you will need to hit the horn button twice in rapid succession immediately after turning the joystick on. You'll know the joystick is locked if the battery level lights go from green to red (right to left). If you are seeing a flashing wrench symbol, that would indicate there's another issue at hand rather than the joystick being locked.
