How do i turn off the lock on the oven

Depends on the radio.
General idea is this:
turn radio power off on face of radio. Clock should show.
push button such as SET / CLOCK / TIME
push other button HOUR MIN up down seek scan ff rew (one button will control hour other button will control minute)
turn radio power back on. clock should remain set.

may i have the model and make of the oven?

try turning power off at electrical main switchboard for a minute, then back on. reset clock and see how it goes.
otherwise > call the repair man.

Have you set the clock alot of ovens need the clock set so the oven will work, this is a safety thing so if you set the oven to turn off after 1 hour or at a certain time of day and say the power went out or the gas was turned off and came back on then the oven won't just start up on its own

Here is what the manual for your oven says about control lock.

Let me know if you have questions.

Control Lock
The Control Lock shuts down the control panel pads to prevent
unintended use of the oven(s). The Control Lock will remain set
after a power failure, if set before the power failure. The only time
it is not available is during the Sabbath Mode or Self-Clean cycle.
When the control is locked, only the TIMER SET · START, TIMER
CANCEL, OVEN LIGHT and CANCEL OFF, UPPER OVEN
CANCEL / OFF or LOWER OVEN CANCEL / OFF pads will
function. On double oven models, CLOCK SET · START will also
function.
The Control Lock is preset unlocked, but can be locked.
To Lock/Unlock Control: Press and hold CONTROL LOCK for
about 3 seconds, until “CONTROL LOCK” and a picture of a lock
appear on the display. Repeat to unlock and remove “CONTROL
LOCK” from the display.

i want to turn off the clock on my whirlpool stove

OK, this is not a good situation here. your Electronic Oven Control board is damaged. the logic sectors are faulty. The F-1 represents a major EOC failuer and, you will need to replace your EOC(clock) asap, if possible.

if the model has a digital clock and when the power went of it may have fried the little computor.if you dont have trip switchs in fuse box
