If your car is saying 'no key detected' but you have the key, there are a few potential issues to check. First, ensure the key battery isn't dead; a weak or dead battery can prevent the key from communicating with the vehicle. Next, check if the car's battery is functioning properly, as a low battery may affect the vehicle's ability to detect the key. Sometimes, interference from other devices can also cause signal disruption. If those steps don't resolve the issue, the car or key might need professional diagnostics to identify a possible malfunction.
