The blade and the chip are separate problems
A correctly cut blade that is not programmed will not start the car. A programmed chip on a badly cut blade will not turn the cylinder cleanly and can damage the ignition.
Both have to be right. That is the whole job.
Cloning vs adding a key in the module
On some older systems a chip can be cloned from a working key. On many later systems the module has to be taught the new key with a diagnostic tool.
Cloning is not a universal shortcut. If someone already sold you a “clone this” key that the vehicle will not accept, the next step is identifying the actual system — not trying a second clone.
Questions people actually ask
My key turns but the car will not start. Is that the transponder?
It is a common symptom of a transponder the vehicle does not recognize, a failed chip, or an immobilizer issue. It is also a symptom of unrelated no-start problems. Diagnosis starts with the year, make, model, and whether a second key exists.
