Radio Code Issues?

When the battery terminals are disconnected the Engine System and internal module gets reset.So when you reconnect the Battery Again,most of the Engine system and module woks fine.But the Radio gets reset.In this cases the 4 or 5 digit Radio code is required,to make the radio work.If you don't have this code then radio will not work.So before disconnecting battery ,please note that you have radio code.


In this case you have 3 viable options:

You can try this:------
pull the stereo, get the serial number off the back, and call your local GM dealer parts department with serial number to get the unlock code.

Take vehicle by a GM dealer after repair and pay them 1/2 hour labor to use a dealer scan tool to retreive the code for you

Go to your local parts store and pay about $30 for a code saver that plugs into the OBD2 connector underneath the left side of dash before disconnecting the battery. This saves the code and automatically unlocks the stereo for you.

This details will help.
Thanks.

Can car radio code block Passkey anti theft system ?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


This both are two different systems.Its not one system.
The Passkey anti theft system and the radio theft deterrent system are completely separate systems, so the answer is no the radio code does nothing to the Passkey. Passkey is a passive system, that is to say it disarms itself and arms itself just by inserting or removing the key from the ignition and locking the door of the car either with the key or the remote. If the Passkey is the source of any problem and is not working correctly then the Security light should be flashing in the dash to indicate a problem. The most common issue with the Passkey 1 and 2 is that the reader located in the ignition switch lock cylinder goes bad, this locks out the fuel pump and the engine will not start. The system can be bypassed but it is not easy.
