This is why it's a great idea to have two working keys for modern vehicles and to have the replacement key programmed if necessary.
A keyprogrammer can reprogram the transponder chip of an entirely new mechanical key or key fob. It is also able to copy the data of an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips can be found in cars that were manufactured within the past 20 years. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your vehicle.
When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle can then 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 turn it on. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce the possibility of theft from your vehicle.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key, and there are a few different cuts that can be found on these keys: a cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal will then get absorbed by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car does not 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 an alarm. This feature is designed to discourage people from attempting to tamper with the vehicle, however it isn't a foolproof security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.
You can see that the transponder is an excellent option. All car owners should consider this when they want to safeguard their investment and reduce theft risk.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate cars or switch on the heated steering wheel. These extra features can make it difficult for you to locate your car keys.
Key fobs communicate with one other and the car using radio frequencies that are transmitted via an antenna that is located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
There are many ways to program a key fob depending on the vehicle's make and model. You can sometimes do this yourself, but most newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When program car keys press the button on a key fob the microchip sends a signal to the receiver inside the car that it is paired. The receiver compares the information 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 able to operate.
Once the car is connected to a specific fob, it can only receive signals from the device. Other fobs won't work with the car, even if they look similar. This ensures the security of the computer system of the car and blocks the use of unauthorized key fobs to gain control over it.
The majority of car dealers who are newer will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by customers without the need of dealers.
