It would be helpful to know what radio you have. The cars originally
came with a glovebox-sized binder which contained the ~200-page Drivers
Handbook and additional fliers on items such as the radio. If you
don’t have that, perhaps you can post a photo of your radio and someone
with your model can provide specific information.
For example, my 89 has the AJ8700 radio, which uses a 5-digit code.
When there has been a power interruption to the radio memory/code wire,
such as by disconnecting the battery, “CODE” appears on the radio
display. You must enter the 5-digit code by slowly pressing one of the
buttons on the top row, which have number labels as well as another
function label. On my model, if ANY beep occurs during code entry, the
radio did NOT recognize that last number entry as a correct element of
the code, and you MUST start over with entry of the first number.
Allow ~ one second between button presses, and fully depress each
button.
If you get a beep during code entry (incorrect entry) in three or more
attempts, the radio will “lock you out” and not accept any code entry
until the radio has been left on (key on) for ~ 1 hour. That may be
your current situation, so allow the radio to be on with the key on for
an hour, and then try to enter the code per the above.
Sometimes one of the buttons may not make proper contact, so make a not
of when any beep occurs during the entry process. If your code were
12345, and it beeped after you pressed 3, that suggest it did NOT
properly receive the preceding press of the 2 key and is accepting 3 as
the second (incorrect) digit.

That’s what I was afraid of - I have a 5-digit code. And the unit
beeps at what seems to be random points when I enter and then re-
enter the code.
I’ve searched through the forum and there seem to be lots of
threads on radio codes. I have yet to find an answer that fits my
radio.
