This can be costly. This is why it's a good idea to have two working keys for a modern automobile and have the replacement key programmed if required.
A keyprogrammer is a tool which can reprogram the transponder chip on a new key fob or mechanical key. It is also able to copy the data of an existing key which allows duplicate keys to be created. 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 can be found in cars manufactured in the last 20 years. It's a small plastic piece inside the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by an antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the right one for the car you have.
This is the reason why from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the key also verifies that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys appear like regular metal keys but they have a plastic cap. The chip is contained in the plastic portion of the key, and there are different cuts that can be found on these keys: a standard cut laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit within the induction coil will emit a signal when the transponder is inserted into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the car doesn't recognize the transponder as being the proper signal, it won't start the engine and warn you with flashing lights and an alarm. This is designed to discourage people from trying to alter the vehicle, but it's not a 100% security measure. A skilled and committed thief could still be able to get around this system using a device that can take over the signal.

A lot of these features might seem useful however they could make it more difficult to keep the keys to your car.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your vehicle. It is possible to do this yourself, however most modern automobiles require 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 a signal to the receiver in the car that it is paired. The receiver then compares the data with the 'allowed signals' stored in the key fob, and then opens or locks the car door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to function.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even though they look the same. This helps to protect the integrity of the car's computer system and prevent unauthorised key fobs from taking control of 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 the only place that has the experience to design a replacement fob is in a dealer's service department. Some aftermarket fobs, usually those from older models with less sophisticated systems can be programmed with out the need for a dealer.
