This is why it's a good idea to have two working keys for a modern car and have the replacement key programmed if needed.
A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It is also able to clone information from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
Transponder chips can be found in cars that were manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the right one for your particular car.
This stops the vehicle from being started through either hot-wiring or by manipulating. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys look like normal keys, but with a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out the signal. The signal will be absorbed by the chip, causing it to transmit a signal to the car. If the computer on the car recognizes this signal as the correct one, it will shut down the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as being the proper signal, it won't start the engine and will warn you with flashing lights and siren. This is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief may still be able to get around this system employing a device designed to intercept the signal.
You can see that the transponder is a good option. Every car owner should take this into consideration if they wish to protect their investment and reduce the risk of theft.
Key Fobs

When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' stored on the key fob and then opens or locks the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once automotive key programming is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, even if they look identical. This protects the integrity of the computer system that runs the car and prevents unauthorized key fobs gaining control of it.
Most dealerships with newer cars will only accept vehicles that have original fobs or genuine replacements sold by the manufacturer. This is because the process of creating the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by customers without the need for a dealership.
