The owner's manual as well as the Workshop Manual both state that three consecutive incorrect attempts at disabling the anti-theft system will render the radio inoperable and that it must be replaced. This is absolutely not true! There is a very simple procedure which will restore your radio to operability. It does not involve removing the radio and requires about 30 seconds to complete.

In the past we had chosen not to publish the code. However, this information was previously released on the net by folks who really didn't think security was important. We believe that poor security is worse than no security since it may lead to a false belief that things are secure when they're far from being so. As a result, we've decided to publish this controversial, yet widely known procedure.

For most 1990 - 1996½ factory radios:

To determine if this radio has been set with an antitheft user code, remove battery power from it for at least 45 seconds. When battery power is restored with no user code set, the radio's operation is immediately restored. If a code is set "cod e" flashes in the radio's display.

When "cod e" flashes in the radio's display after battery power is restored, and you know your antitheft user code, the radio's operation can be restored by following your Owner's Manual "If Antitheft system is Activated" procedure. If you don't know your antitheft user code, or to remove one previously set, follow the same procedure three times entering an invalid 1 to 4-digit user code each time. Once an invalid 1 to 4-digit user code is entered three times, "err" flashes in the radio's display. When flashing "err" displays, the radio is now set to accept the following re-set procedure.

Press the # 1 button

Press Stop/Eject

Press Am/Fm

Press Clock Button

-- -- -- -- Will appear.

Enter code 4 9 8 9

Press F/Forward & Reverse at the same time and hold for a couple seconds.

The code should now be removed. Follow the instructions in your manual to set a new code.

For 1996½ - 1997 (has number 1273 on it)

To determine if this radio has been set with an antitheft user code, remove battery power from it for at least 10 seconds. When battery power is restored with no user code set, the radio's operation is immediately restored. If a code is set "code" flashes in the radio's display.

When "code" flashes in the radio's display after battery power is restored, and you know your antitheft user code, the radio's operation can be restored by following your Owner's Manual "System activation" procedure. If you don't know your antitheft user code, or to remove one previously set, follow the same procedure three times entering an invalid 1 to 4-digit user code each time. Once an invalid 1 to 4-digit user code is entered three times, "err" flashes in the radio's display. When flashing "err" displays, the radio is now set to accept the following reset procedure.

Press Scan

Press AM/FM

Press Prog/Auto M.

Press FForward

This should give you the "- - - -"

Enter 4 9 8 9

Press Prog/Auto M. first, then press Scan (Hold both buttons down at the same time and make sure to follow this order. If you reverse the order it will not work.)

The display should now read "Good" The radio should now work again."
