What should one do if the "Code" light stays on the dashboard?
If a yellow padlock or "Code" light stays lit up, the immobilizer does not recognize the secret. This might be due to a defective transponder, a damaged antenna ring around the ignition barrel, or a blown fuse. An expert diagnostic tool is needed to determine the fault.
