I was given a stock head unit from a friend but when i went to plug it in the display says locked. Can the dealer unlock it if i take to them? In advance thanks guys

 

what year radio? theres a series of buttons you can push on some to get a code the dealer will need to get the unlock code. Also try 0000

 

its out of an 05 and my truck is an 04. i read that i need to get the serial numbers to get the code but can only the dealer unlock it or can i do it

 

i want to know also. just tried to do the same thing... 05 radio in my 04.

thanks,
Lance

 

1fastbrick found some great info on this- i will post it up

 

1. Turn the ignition ON (The radio displays "LOC")

2. Press and hold presets buttons 2 & 3 or 1 & 4 for approximately 10 seconds. The radio display changes from "LOC" to a three-digit number. Write this number down. If you have a Saturn or GEO, see note below and skip to step 6.

3. Don�t take long, fifteen seconds max before the next step

4. Press the AM/FM button. The radio display changes to another three-digit number. Write this number to the right of the first one.

5. You now have a six-digit number, the first three digits are from STEP 2 and the last three digits are from STEP 4, so you will have a number like this ( 212 - 212 )



With your new-found 6-digit code, call 1-800-537-5140. It's just an electronic answering machine. Once the guy finishes talking, press 202108, followed by the *Asterisk* button (not pound).

He'll then tell you to enter in your 4- or 6-digit code, followed by the star/asterisk again. So, type in the numbers you got out of your radio, and hit star/asterisk.

He'll then tell you your 4-digit unlock code. Write it down.

Now you can go back out to your truck, press and release the "HR" (hour) button until it flashes, and enter in the first two digits of your 4-digit code. Then press the MIN (minute) button and enter the last two digits. When you've enteted the code, hit AM/FM. The radio should now be unlocked.

 

I put in my buddys 6 disc head unit in my truck and it was locked the dealer charged me $100 to unlock it. they had some web site they went to that gave the code to them. both trucks where 2006. hope you get it worked out let us know what you had to do, i would like to know if there is a way we can do it our selfs and save the $100 the dealer charges.

 

did you not read my post?

 

Is that proven to work?

 

I will let you know tonight when I try it
