Why Does My Vehicle Say Key Not Detected?
The car cannot see the smart key. Most often that is a flat key battery, the key being shielded by a phone, a wallet or metal, interference nearby, or a fault in one of the vehicle's antennas. Many cars have a backup position — often against the start button or in a marked slot — that will let you start once.
