This is why it's a great idea to always have two keys working for a modern automobile and have the replacement key programmed if necessary.
A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It can also clone information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers. They also feature a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car was built within the past 20 years, it is likely that it has a transponder inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This prevents the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the person who owns the vehicle. This helps to prevent car theft.
Transponder keys resemble regular keys made of metal but they have a plastic cap. The chip is located inside the plastic part of the keys. There are various cuts such as a standard cut a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal will then get received by the chip, causing it to transmit a signal back to the car keys cut and programmed. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle does not recognize the transponder signal as being the right one, it will prevent the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and determined thief could still evade this system with a specially designed device that detects the signal.
You can see that the transponder is an excellent option. This is something that all vehicle owners should consider if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today be more than just a way to lock and unlock doors. They can also start your vehicle remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. A lot of these features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs make use of radio frequencies to communicate with each other and the car. These frequencies are sent via a small antenna that is located inside the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal.
There are several ways to program a key fob depending on the make and model. You may be able to do it yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob.
When you hit the button on a key fob the microchip inside sends an encoded code to the car's receiver that it is paired with. The receiver compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is linked with a specific fob, it will only accept signals from that specific device. In turn, other fobs will not work with the vehicle, even though they appear similar. This ensures the security of the computer system in the car and prevents unauthorized key fobs gaining control over it.
Most newer car dealerships will only work with vehicles that have original fobs or genuine replacements offered by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
