Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
What is the problem you are having? Thanks.
C0569 means EBCM needs to be reprogrammed and/or replaced. B3105 sets if there are no keyless entry transmitter programmed to the RCDLR and usually means the Remote Control Door Lock Receiver (RCDLR) needs to be replaced. Let me know if you have questions, thanks.
A tech2 scantool is needed which is a dealer scantool. They will charge about a hour labor to reprogram both components. I would replace the RCDLR yourself then bring to dealer for programming. Let me know if you have questions, thanks.
