A reprogrammed key will need to be compatible with the exact identification number of the vehicle or else it won't be able to start the engine.

Transponder chips are a standard feature of modern cars and are designed to prevent car theft. The chip is a tiny microcircuit that emits a radio frequency signal when the ignition key is inserted. The car then detects the signal and then starts the engine if it is in line with the original one that was programmed into the vehicle. The car will also shut down if a frequency is not valid. This makes it much more difficult for car thieves with no experience to wire a vehicle and then start it.

The chip and the key are connected via a circuit board that includes an induction coil. When the key is placed in the ignition it creates an electric field around the transponder. This generates a signal that is absorbed by the coil and then transmitted to the key's identification. The ID number of the key is then sent back to the vehicle and if it matches the engine will begin to run.

There are many methods to program a key transponder, but each requires the use of a specific tool. These tools are available through the internet or from many automotive locksmiths. These tools are not cheap but are essential for programming your car's chip.
