GM DELCO THEFTLOCK RADIO UNLOCK CODE:
1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down.
2. After doing step one and writing down the code, immediately press
the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over).
3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if
you're
calling for Chevy, Pontiac, Cadillac, etc... When you here him tell
you
to press "2" for Pontiac, press 206010 and hit the # key. He'll ask
you
for the 6 digit code that you've written down. Enter that and press
the
* key. He will then give you a code, and the option to get additional
4
digit codes, but one should be sufficient.
4. Follow the normal procedure in your owners manual for unlocking the
radio with your new code...press the hour set button on your radio
until
you get the first two numbers of the code, then press the minute set
button until you've entered the last two numbers. Immediately press
the
AM/FM button once the correct code is entered and the code SEC or
"secured" will be displayed on the display screen. Now, just turn the
radio on, and your ready to roll.
There is an additional step you can take to remove all codes from the
radio and start from scratch by entering your own personalized 4 digit
code so that it won't get you in a pickle again! Just repeat step 4
and
you should get a display screen that reads ---. This means the code is
out, and you can now program your own code. Of course, once you
receive
the 4 digit code from the GM recorded message, just keep it in a safe
place, because you can use that same code again and again should you
have any more problems with it in the future. Good luck, and yes, it
does work.

i found it best to remove radiator first before trying to tackle the alternator... once that is removed then you can easily get to it to unloosen bolt and swap

SOURCE: replacing fuel pump on 1995 oldsmobile aurora

The GM 1995 Aurora repair manual, says to use the access hole under the carpet in the back right corner of the trunk. You are best to buy a new fuel sender locking nut or ring at the dealer for about $8.


Forgot to add this - to relieve the fuel pressure, just use the press the center of valve on the fuel rail (for pressure testing) and a rag to catch the dribble. Really no big deal.

Make sure disconnect the battery cables too

What is the security code?


Your SECURITY light lit on the instrument cluster ? or you disconnected the battery an now the radio is locked ?
The theft deterrent system on this vehicle is comprised of the vehicle theft deterrent (VTD) system. VTD prevents drive away theft by preventing the vehicle from starting.
SECURITY Indicator The SECURITY indicator on the instrument cluster is controlled by the VTD system. The SECURITY indicator is located inside the instrument cluster. The SECURITY indicator is controlled by the body control module through the class 2 data line. The VTD system contained in the BCM commands the instrument cluster to control the SECURITY indicator only when the ignition switch is ON. The VTD system uses the indicator as a malfunction indicator.
Theft Deterrent
The "Theftlock" theft deterrent system is a feature on all base and uplevel radios. There is no need to program a security code into the radio as in past model years. The theft deterrent system now utilizes class 2 serial data to determine if the radio is in the appropriate vehicle. Each time the radio receives the "run" power mode message, it compares the VIN information it has stored to the VIN information received from a module on the class 2 serial data circuit responsible for transmitting that information. If a mis-match occurs, the radio display will indicate to the user the radio is locked. Once this takes place, a DTC will set, the radio will not respond to any button presses and become inoperative. The two scenarios able to cause this condition are:
?€¢
A radio is installed from another vehicle.


?€¢
A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle.

The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.
So what problem are you having ?

I NEED TO UNLOCK MY STERO IN A 2004 TAHOE


There is no actual "security code" in the radio as in past model years. The newer theft deterrent system utilizes the class 2 serial data to determine if the radio is in the appropriate vehicle...in other words it compares the VIN it has stored in it's memory with the VIN of the other modules (body control and PCM) in the vehicle to "check" to see that it's in the correct vehicle.

Each time the radio receives the "run" power mode message, it compares the VIN information it has stored to the VIN information received from a module on the class 2 serial data circuit responsible for transmitting that information. If a mis-match occurs, the radio display will indicate to the user the radio is locked. Once this takes place the radio will not respond to any buttons/commands and becomes inoperative. But the dealer can reestablish the radio into a different vehicle with a scanner.

There are 2 types of GM Theftlock, Theftlock I and Theftlock II. The Theftlock I is found in pre 2000 vehicles, and Theftlock II is in the later models.


Theftlock I - Uses a volatile user settable code that is input through the key pad on the front of the Radio. If the power is lost (dead battery etc.) the code is gone and must be re-entered for the radio to work. But with the correct procedure the owner can unlock it.

Theftlock II - Uses an EPROM (erasable/programmable read only memory) or a PROM (the difference is you can not alter the prom once it is programmed).

In either case the code is burned in and holds even when the power is lost. With Theftlock II the radio is married to the vehicle by way of the VIN. When the vehicle is started the computer compares the number in the radio with the VIN in the body control module. If they match, the radio works, if not the radio displays LOC and you are finished, there is no easy way around it. The radio will not work until you make a trip to the dealer.

The dealer will use a TECH 2 scanner to change the VIN stored in the radio. The radio does not need to be removed (for the serial number or any other nonsense). The technician just plugs into the computer and resets the VIN in the radio.

Thank you for using fixya and good luck. you might get luck by removing the fuse toy our radio for 5 min and reinstalling it, this will reset the radio to default and all you need to do is reset the clock and radio presets.

if you bought the car new then there should be writen in the manual the code for the theft lock system on the radio. if pre-owned then it might ,might not be in there. or if you dont have one at all. go to your nearest GM dealer and have them fix it by finding the code. make sure to have them write it down for you incase this happens again.
