This could be costly. This is why it's a great idea to always have two keys working for a modern automobile and to have the replacement key programmed if required.
A keyprogrammer can recode the transponder chip on a new mechanical key or key fob. It also can clone information from an existing key to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.

Transponder Chips
If your car is made within the past 20 years, then it has a transponder inside of it. It's a tiny plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
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 attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip in the key is the correct one for your particular car.
This stops the vehicle from starting by hot-wiring or altering the key. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Transponder keys appear like normal keys, but with caps made of plastic. The chip is contained within the plastic part of the keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit within the induction coil emits signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer on the car recognizes this signal as being the correct one, it will turn off the vehicle's immobilizer and allow the engine to begin.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding a siren. This is designed to discourage people from trying to tamper with the vehicle, however it is not a foolproof security measure. A determined and skilled thief can still get around this system by using a specific device that detects the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners must take this into consideration when they want to safeguard their investment and minimize the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding cars, or switch on the heated steering wheel. A lot of these additional features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted through a small antenna located inside the middle of the key. The signal is encrypted to stop others from stealing or modifying the signal.
There are many ways to program a key fob, based on your vehicle's make and model. Certain models allow you to do this by yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.

When you press the button on a key fob, the microchip sends an indication to the receiver inside the vehicle with which it is linked. The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car is connected to a specific fob, it can only receive signals from the device. In turn, other fobs won't be able to work with the vehicle even though they look the same. This protects the integrity of the computer system in the car and prevents the use of unauthorized key fobs to gain control of it.
Most dealerships with newer cars will only deal with cars with original fobs or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that is only available in the dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need of a dealership.
