The key you reprogrammed needs to be matched with the exact identification number of the vehicle otherwise it won't even start the engine.

Transponder chips are a common feature of modern cars and are designed to stop car key cut and program theft. The chip is a microcircuit that emits a radio frequency signal when the ignition key is placed. The car is able to detect the signal and starts the engine only if it matches the original that was programmed into the vehicle. The car is also programmed to shut down when it detects an incorrect frequency. This makes it more difficult for thieves who aren't experienced to wire a vehicle hot and then start it.

A circuit board with an induction coil that connects the chip to the key. When the key is put in the ignition the magnetic field is generated around the transponder. This generates a signal, which is taken up by the coil before being sent to the key identification number. 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 several methods to program a transponder key, but they all involve using an appropriate tool. These tools are available on the internet or at most auto locksmith key programming locksmiths. They're not cheap, but they are crucial for programming the chip in your vehicle.
