Here's a couple things to try, I don't know if any of them will work, but it's worth a try. Also you could call your dealer and see what they say, they should be able to do it very easily

 

"** Theftlock Bypass

 

1. Press and hold presets 2 & 3 for about 10 seconds until the first 3 digits of the display code are displayed.

 

2. Write the numbers down.

 

3. Press the AM/FM button, write down the next 3 numbers.

 

4. Call 1-800-537-5140, when asked, enter 620529, press the # button and enter the 6 digit code from the radio, you will get an unlock code, write it down.

 

5. Go back to the car, press the HR button and set the first 2 numbers, then press minute button and set the next two last numbers, press AM/FM button, SEC should be displayed, turn on radio.

 

To remove customers code, repeat step 5. you should see --- on radio face, the code is now out of the radio.

 

 

 

EDIT: Updated with new dealer code. FWIW, the old code was 202107"

 

 

Here's another site that looks like it would work

1. Press and hold presets 2 & 3 for about 10 seconds until the first 3 digits of the display code are displayed.

 

 

I don´t now what are presets 2 & 3 is, my Navigationsytem have no number buttons

 

can anybody explain ?

[700 sportsman]

I guess that would not be the correct method for your radio then, I would do some more searching online, but I do believe you will have to have your dealer program it with Tech 2

[Matze8691]

can you look for me

 

please, in germany nobody can help me................

 

And tec 2 is all free

 

I need the radio code

[700 sportsman]

I'll see what I can find, but it may be a couple days, I've been very busy.

 

Also, could you get me the model/part number of the radio, that may help too

[700 sportsman]

Also, what year is your hummer, and what year is the radio from?

[Matze8691]

The hummer is year 2004

 

the radio is 2004

 

and the serial number is: 99DWJRR232390374

[700 sportsman]

Ok, well I found to make sure the radio is compatible with your hummer, and will function properly.

 

To do this, you will nee to put the keys in the ignition, and turn it to the accessory position, and then disconnect the battery for 3 to 5 seconds, (leave the keys in the ignition while unhooking the battery).

After reconnecting the battery, the radio should function normally until the key is removed from the ignition.

 

However, this is only a temporary solution. I will see if there is a way to permanently unlock it without Tech 2 at the dealer, but I do not think it can be done

[700 sportsman]

I need the part number on the radio, not the serial number.

[Matze8691]

15204335 was the part number

 

sorry

[Matze8691]

Also when i do what do you say´s

works the radio but when I start the car.................................

 

comes Theftlock

[MS3DALE]

I never get into the radio unlock issues/codes at the dealership (I leave that to the techs.) but I'm pretty sure your going to need a Tech2.

[700 sportsman]

Thanks for chiming in Rich.

 

I hate to say it Mathias, but I think you'll have to find a dealer or someone with Tech 2, or get a different aftermarket radio without theftlock.

You need a Tech-2 and a TIS terminal to reprogram the Nav Theft.
