Locked infinity rsd radio in 2002 chevy venture

Check the fuses. If they are good then you need to pull the radio and check the 2 power wires and 1 ground with a test light. If they are intact then your radio is bad

Look for smaller coolant lines coming off the back of the block or going into the firewall pretty sure it's in the dash

Take it to the dealership, they can unlock it there.

I’m happy to help further over the phone at https://www.6ya.com/expert/michael_195f36f311cb10df

trying to unhook the battery for 24 hours should work then

You will have to contact your Chevy dealer.

Dont know if this will help but try www.radio-code.com good luck, if not its a trip to the dealership.

I had that exact code a couple weeks ago. Mine needed new oxygen sensors. They(there are 2, only one was throwing a code, but I had both replaced) cost a little over $100 to have replaced.

check for an open door ( all doors ) , defective courtesy light door switch, or short in interior light electrical circuitry.

Take it by a GM dealer, they can get the unlock code for you!
it's a security feature in the radio.

Please rate well! Thanks!

the dealer is fulla **** sorry ,the radio is locked but not tied with the vin
and if u take your battery lead off then put back on it will ask you for the code and same if u take it out
the way to get the code is in your manual for the car
or ring the company who made the radio
so what the dealer is saying if it cant be unlocked when u replace the battery it will need a code what do u do ? of course u can unlock it
just do what i said above and u will have your code usaually 4 or 5 digits
