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 needed. A keyprogrammer can reprogram the transponder chip of a new mechanical key or key fob. It is also able to copy information from an existing key to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which allows them to communicate with computers.

Transponder Chips If your car is made in the last 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle. When it is activated by an electromagnetic field, the chip emits a low level signal. This signal then gets amplified by the specific antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle will then confirm that the transponder chip of the key is the right one for your car. This prevents the vehicle from being started by hot-wiring or manipulating. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft. Transponder keys look like normal keys, but with a plastic cap. The chip is contained in the plastic portion of the key and there are different types of cuts on these keys: a standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key. A circuit within the induction coil emits an electrical signal when the transponder is placed in the the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to start. If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it's not a 100% security measure. A determined and skilled thief can still get around this system by using a specific device that blocks the signal. It is evident that a transponder is a great option. This is something that all car owners should consider if are looking to safeguard their investment and decrease 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 car remotely, make chirping noises to help locate a car or switch on the heated steering wheel. A lot of these additional features may appear convenient but they could make it harder for you to keep track of your car keys. Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are transmitted through a small antenna located in the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal. Keyfobs can be programmed in different ways based on the model and make of your vehicle. You can sometimes do this yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on a key fob the microchip sends signals to the receiver inside the car that it is paired. The receiver then compares this information with the signals that are allowed in the fob and then either opens or locks the door. If the information does not match the fob's information, the car won't be allowed to run. Once the car is linked 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, despite the fact that they look like. This ensures the security of the computer system that runs the car and blocks unauthorised key fobs from taking control of it. Most newer car dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is because preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Some aftermarket fobs, usually those from older models that have less advanced systems can be programmed without the need for a dealer.
