How Can I Unlock a Radio on a 94 Impala?

The radio installed in a 1994 Chevrolet Impala is a Theftlock radio. This type of radio has an integrated security system that, depending upon user settings, locks the radio when it loses battery power. This system is primarily designed to discourage radio theft by rendering the radio useless to a thief who doesnt know the security code. In order to unlock the radio, youll need to locate the unlock code that was included in the Impala's owner's manual. If you dont have an unlock code, you can obtain one from your local Chevrolet dealership for a small fee.

Instructions

1

Insert the key into the ignition and turn it to the ON position. Turn off the radio so that the time shows on the radio display.

2

Press buttons 1 and 4 simultaneously until the SEC reads on the radio display. If SEC does not display then you didnt press the button simultaneously.

3

Push and hold the MIN button on the radio until 000 shows on the display.

4

Release the MIN button. Press and release the MIN button repeatedly to cycle the last two digits of the code until they match your security code.

5

Press and release the HR button repeatedly until the first to digits of the code appear on the screen.

6

Press the AM/FM button. If the display reads --- then the radio is unlocked. If it reads SEC then it is still secured and youll need to repeat this process.
