This is why it's a great idea to always have two working keys for a modern car and to have the replacement key programmed when required.
Keyprogrammers can recode the transponder chip of an entirely new mechanical key or key fob. It also can clone 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 allows them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car was built within the past 20 years, chances are it contains a transponder chip within of it. This is a little plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your vehicle.
This is what prevents hot-wiring or tampering with the vehicle's ignition system to start it. The chip inside the key ensures that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is inside the plastic portion of the keys. There are several different cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and 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 will then get taken up by the chip and cause it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as being correct it will turn off the car immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the correct 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 those who would attempt to alter the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief could still evade this system using a special device that blocks the signal.
As you can see there are quite number of benefits to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking lot, today's key fobs can also switch on a heated steering wheel or roll down all windows with a single press. These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps keep others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the make and model of your car. Certain cars let you do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a new key fob or additional one.
When you press the button on your key fob the microchip inside sends an encoded code to the
car key programing's receiver it is linked to. The receiver compared this information with the 'allowed' signals on the fob and either opens or closes the door. If the information isn't in line, a chirping sound is heard and the car isn't permitted to operate.
Once the car is linked 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, even though they look similar.
