Disable the Dealer Lock on a Koss DVD Player

A TechLore "Ask the Experts" Question...


I cannot open my Koss DVD player. Message says "Dealers lock is on". How do I unlock it?

The machine is one year old and has been working fine. Please help! All there Xmas dvds to watch!

Thank you.


To disable the dealer lock on any model Koss DVD player, please follow the steps below:

  1. Turn off the power to the DVD player
  2. Press and hold the stop & power buttons on the DVD player's remote simultaneously. Aim the remote at the DVD player.
  3. Press the power button on the front of the DVD player, while continuing to hold the stop and power buttons on the unit's remote.
  4. When the unit is powered on, the dealer lock will be disabled.

I tried that for about 10 minutes, got really frustrated and then tried another website which had a solution that worked. Press and hold stop on the DVD player and at the same time press power on the remote. That worked...
