GM Theftlock Lockout

candyliquor35m

I have a 97 Pontiac Trans sport minivan that the previous owner must have locked up the GM cd player possibly by trying too many codes. Nothing is displayed such as LOC or INOP but the theftlock led is blinking. I found these instructions but they didn't work. The dealer wants to charge me $44. The dealer and the manual says I have to leave the key in the on position for 1 hour but then after that I'm not sure what to do. The manual says to press 1 and 4 for 10 seconds but that didn't work. These instructions say to hold 2 and 3 for 10 seconds but that didn't work. Any ideas? Thanks.

The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode NOT in INOP mode. Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Y2K Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere).

Procedure:

01. Turn the ignition ON (The radio displays LOC)

02. Hold down the Radio Presets 2 and 3 buttons for six seconds

03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step.

04. Press the AM/FM button

05. The radio display changes to another three-digit number. Write this number to the right of the first one.

06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05

07. Call 1 800 537 5140

08. Press 1 then # (pound). You’ll hear “Invalid Code, try again”

09. Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start)

10. Enter the number from STEP 6 then * (star)

11. Listen to the four-digit number and write it down. It will be repeated twice

12. Turn the ignition ON (The radio displays LOC)

13. Use the MN and HR buttons to enter the code from STEP 11

14. Press the AM/FM button. The radio display changes to SEC Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction in your Owner’s manual. Use the code from STEP 11 instead of your personal code.

Cody,

That's what I tried but nothing ever displays, not loc or inop or any numbers. I left the ignition in the on position for 1 hour twice and nothing happened and I tried pressing 2 and 3 for 10 seconds the first time and 1 and 4 for 10 seconds the second time. still nothing.

I might do that if I didn't plan on selling it soon. I may try it a couple more times and then take it to the dealer as long as they agree to not charge me if they can't get it unlocked.

i hate those head units, give me a normal cd player anyday

exalted512

i dunno why they put that crap on there. No one is going to take the time and risk of getting caught to steal a POS factory hu...

This turned out to be a light bulb for the led. When I snapped off the front of the unit, I noticed a twist out miniture bulb and ordered one from a radio shop that the dealer recommended. $6 shipped. Installed the bulb and the led lit up. I followed Cody's instructions and got it unlocked. thanks.

Jesus Christ!

How ironic is that?

A crappy OEM head unit barely worth $50 and you have to go thru all that crap, but a $500 Alpine or Pioneer and all you get is a detatchable face!

Those OEM radios communicate with the engine's computer, and require the radio's code be sent to and recognized by the ECM to operate. A dealer may hold the answer to reprogramming it, but since GM thought people would actually be stealing those factory radios they've made your life difficult (for no reason).

You can usually find the instructions on google or yahoo or one of the automotive help forums for your particular car. Don't give up. The unlocking takes minutes to do but the dealer will probably charge you $50-$100 to do it.

In some cases depending on the model, you have to let the car sit with the key on (not running) for 1 hour before you press the designated 2 buttons.
