This is why it's a good idea to have two keys that work for a modern car, so you can get the replacement key programmed if needed.
A keyprogrammer can reprogram a transponder chip on an entirely new mechanical key or key fob. It is also able to copy information from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. This is a little piece of plastic in the head of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. This signal is then absorbed by a special antenna that is attached to the ignition barrel. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started by hot-wiring, or by altering the key. The chip inside the key also proves that you are the legal owner of the vehicle. transponder key programming will help reduce car theft.
Transponder keys resemble normal keys, but with caps made of plastic. The chip is housed within the plastic part of the key and there are a few different cuts that can be found on these keys: a standard cut, a 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 a signal. The signal is received by the chip which sends a signal to the vehicle. If the computer inside the car detects the signal as being correct it will turn off the car immobilizer so that the engine can start.
If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal could still evade this system using a special device that intercepts the signal.
You can see that the transponder is a good option. This is something that all car owners should think about if they want to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking lot, today's key fobs can also turn on a heated steering wheel, or roll down all windows with a single press. A lot of these features may appear convenient, but they can also make it more difficult to keep the keys to your car.
Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted by a small antenna located in the center of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your car. Some cars allow you to do this by yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or an additional one.
When you press the button on a key fob the microchip transmits an indication to the receiver in the car with which it is paired. The receiver then compares this information to the 'allowed' signals on the fob and either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a specific fob it will only receive signals from that device. Other fobs won't work with the car, despite the fact that they appear similar. This protects the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most newer car dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place that has the experience to design a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by customers without the need for dealers.
