This is why it's a great idea to always have two working keys for modern vehicles, so you can get the replacement key programmed when needed.
Keyprogrammers can recode a transponder chip on the new mechanical key or key fob. It is also able to copy information from an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide bidirectional interfaces to work with the 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. This is a little plastic thing inside the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is taken up by an antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the car key ensures that the owner is the person who owns the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip is housed in the plastic portion of the key and there are different kinds of cuts available on these keys: a cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits signals when the transponder is inserted into ignition barrel. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm. This function is designed to discourage individuals from tampering with the vehicle. However it isn't a foolproof measure of security. A determined and skilled thief could still bypass this system using a special 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 decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding the car in a parking space Key fobs today can also activate a heated steering wheel, or roll down all windows with a single button click. These extra features can make it difficult for you to find your car keys.
Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted by a small antenna within the middle of the key. This communication is encrypted to prevent others from stealing or modifying the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. You can sometimes do this yourself, but the majority of newer automobiles require an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is linked. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
When a car is connected with a specific fob it will only accept signals from that specific device. As a result, other fobs will not work with the vehicle even though they look the same. This helps to protect the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
