This is why it's a good idea to always have two keys working for a modern automobile, so you can get the replacement key programmed when needed.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It can also clone the data of an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips
If your car was manufactured in the last 20 years, then it contains a transponder chip within of it. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna attached to the ignition barrel. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for the car you have.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with a plastic top. car key programming is inside the plastic portion of these keys. There are car key programming that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This function is designed to discourage individuals from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief may still be able to get around this system using a special device to detect the signal.
You can see that a transponder is a great option. This is something that all car owners should think about if they are looking to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making sound chirps to help locate a car in a parking lot Key fobs today can also turn on the heated steering wheel or roll down all windows with a single button press. These additional features can make it difficult for you to find your car keys.
Key fobs utilize radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. Certain models allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob, or an alternative one.
When you press the button on a key fob the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the information isn't in line an chirping sound is heard and the car isn't allowed to operate.
Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, despite the fact that they appear similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. Some aftermarket fobs, usually those from older models with less sophisticated systems can be programmed with out the need for a dealership.
