Tip & How-To about 2000 Chevrolet Blazer

Need a radio code for your vehicle?

F you ever remove the battery or radio from most vehicles and upon reinstalling what was removed the radio will not work at all until the code is installed back into the radio
This pertains to disconectiong the battery and or the radio
You can have this code installed at the dealer that sold this car when new or you can go the the website I have posted below
The charge to obtain the needed code is far much less to pay from the posted website I have posted
Any dealer will charge you at least one hour book time to perform this installation
Most labor book hours are well over $100 these days
This website has an average charge of $20, some can be more depending on the vehicle
This information is explained in a well worded manner to understand
Here is the website

Turned radio off then battery died, got vehicle fixed but no power to factory radio, all fuses check as good. Is there a trick to getting the radio to turn on again?


when the battery dies or is removed , the anti-theft code of the radio kicks in and the unit will not work again until a special code for that radio is reinstalled
the code could be in the user manual in the radio use section ,or there are sites on the net that may have the code for you

Replaced factory radio and then put factory back in. Screen read locked, Removed chip and now states call truck will not start. New alternator and battery. Whats up?


the radio once it is removed from a power source will automatically go into theft mode and will not power back on until the code is reinstalled
that has nothing to do with the chip
If you have interfered with the chip in the ECM then you will need to reset the CPU program in the ECM using a scan tool
what you have stated indicates that you need a workshop manual to read what not to do with a vehicle
