How to Unlock a Zenith TV

By William Pullman

Zenith televisions are designed with one or two different types of locks. The first is the child lock, which allows parents to block specific channels or types of programming they deem unsuitable for their children. The second is the key lock, which makes the buttons on the front of the television inoperable. The television locks also prevents you from watching the same channels or programming and prevents use of the buttons on the television until you unlock these features.

Child Lock

Step 1

Tune the television to a channel blocked by a child lock. The words "Enter Lock Code" will appear on the screen with four dashes underneath.

Step 2

Press the numbers on the remote control to enter the child lock pass code to unlock your Zenith television. When the code is entered correctly, the blocked channel becomes visible. The words "Enter Lock Code" remain on the screen if the password is not correct.

Step 3

Enter "0000" if you did not change the password on the television prior to enabling the child lock feature. This number is the default pass code for the child lock.

Step 4

Push "7777" if you changed the pass code for the television but no longer remember the code. This number allows you to bypass the child lock and watch the programming.

Key Lock

Step 1

Press the "Menu" button on the remote control to access the "Main Menu" screen on the television.

Step 2

Scroll to "Special" using the up or down arrow buttons and press the right arrow button to access the "Special" sub-menu.

Step 3

Push the up or down arrow button to highlight "Key Lock" and then press the right arrow button.

Step 4

Press the up or down arrow button to change "Key Lock" to "No" and then press the "Menu" button to save the setting.
