Having problems with your 1998 Pontiac Grand Prix ?
How do I put in a radio lock code for a 98 Pontiac Grand Prix?
The radio comes with a preassigned lock code that must be obtained from Pontiac. They will need you to follow these steps to retrieve two sets of numbers for them to call GM and obtain the assign lock code for your radio. STEP ONE: Press number 2 and number 3 simultaneously. Hold until the first set of numbers appear. Then press the AM/FM button on the radio for the last set of numbers to appear. Give those numbers to Pontiac, and they will call for the radio lock code. They will also provide you the steps to enter that code to unlock your radio.
