This is why it's a great idea to have two working keys for a modern automobile and have the replacement key programmed if needed.
Keyprogrammers are devices which can reprogram the transponder chip on a new mechanical or key fob key. It is also able to clone information from an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port.

Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder chip inside of it. It's a small piece of plastic inside the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then taken up by an antenna attached to the ignition barrel. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for the car you have.
This prevents the vehicle from being started by either hot-wiring or by manipulating. The chip in the key also verifies that you are the genuine owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is housed inside the plastic portion of the key, and there are a few different kinds of cuts available on these keys: a standard cut laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the car's computer detects this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will notify you via flashing lights and a siren. This feature is intended to discourage people from attempting to hack into the vehicle, but it is not a foolproof security measure. A skilled and committed thief may still be able to get around this system employing a device designed to intercept the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should consider if they are looking to safeguard their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate the car in a parking lot, today's key fobs can also activate a heated steering wheel or roll down all windows with a single press. Many of these extra features may appear convenient, but they can also make it more difficult to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are transmitted through a small antenna located within the middle of the key. The transmission is encrypted, which helps prevent others from intercepting and retransmitting the signal.
You can program a keyfob in different ways based on the model and brand of your vehicle. It is possible to do this yourself, but most newer cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob, the microchip transmits a signal to the receiver in the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the information isn't in line, a chirping sound is heard and the car isn't able to operate.
Once the car is linked with a particular fob, it will only accept signals from the device that is associated with it. Other fobs won't work with the car, even if they appear similar. This safeguards the integrity of the computer system in the car and prevents unauthorised key fobs from taking control over it.
Most newer car dealerships will only deal with vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise which can only be obtained in the dealer's service department. Some fobs from the aftermarket, especially those for older models with less advanced systems can be programmed without the need for a dealer.
