This is why it's a great idea to always have two keys that work for modern vehicles and to have the replacement key programmed when required.
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 and allow duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers.

Transponder Chips
Transponder chips are likely to be found in cars manufactured within the past 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 the vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is positioned around the barrel that controls your ignition in your car. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This is what stops hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the car key ensures that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys resemble normal keys but have caps made of plastic. The chip is housed in the plastic portion of the key, and there are different types of cuts on the keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it will not start the engine and will alert you with flashing lights and an alarm. This function is designed to discourage people from tampering with the vehicle. However it isn't an unbreakable security measure. A skilled and committed thief may still be able to bypass this system by employing a device designed to detect the signal.
As you can see, there are quite a number of advantages to having a transponder key. All car owners should consider this if they wish to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to help locate the car or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted through an antenna in the center of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your vehicle. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or an additional one.
When you press the button on a key fob, the microchip sends an indication to the receiver inside the car that it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the information does not match the fob's information, the car won't be allowed to drive.
Once the car has been connected to a specific fob, it will only accept signals from that device. Other fobs will not work with the car, even though they look identical. This protects the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models that have less advanced systems can be programmed with out the need for a dealership.
