How to Open Maytag Dryer Locks Without Keys
The only lock function that Maytag dryers have are control locks. When the control lock is activated, the buttons on the control panel will not change the dryer's settings. You do not need keys to turn off the control lock. As long as you know which button to push, you can turn off the control lock using the control panel.
Locate the "Cycle Signal" button on the control panel.
Press and hold the button for three seconds.
Release the button. The control panel now is unlocked.
