This is why it's a good idea to have two keys that work for a modern automobile and to have the replacement key programmed when needed.
Keyprogrammers are devices that recodes the transponder chip on the form of a new key fob or mechanical key. It also can clone data from an existing key to create duplicates. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with computers. They also have a bidirectional user interface that works with an immobilizer system.

If your car was built within the past 20 years, chances are it has a transponder inside of it. It's the tiny plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electro-magnetic field the chip emits a low-level signal. The signal is then amplified by the specific antenna that is fitted around the ignition barrel of your car. This allows the car's computer system to verify that the transponder chip that is in the key is the right one for your particular car.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to start it. The chip inside the key also confirms that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys that are regular in shape like regular keys, but with an outer layer of plastic. The chip itself is housed within the plastic part of the key, and there are a few different kinds of cuts available on these keys: a regular standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
A circuit inside the induction coil will emit a signal when the transponder is placed in the ignition barrel. The signal will then get absorbed by the chip, causing it to send a signal back to the car. If the computer inside the car is able to recognize the signal as correct it will turn off the car immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and will warn you with flashing lights and siren. This feature is designed to discourage individuals from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still evade this system by using a specific device that blocks the signal.
You can see that the transponder is a good option. This is something that all car owners should consider if they want to safeguard their investment and decrease the chance of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start your car from a distance, make chirping sounds to aid in finding the car, or turn on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are a few different ways to program a key fob depending on the vehicle's make and model. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a replacement key fob, or an alternative 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 compares this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the data does not match, the car will not be allowed to run.
After the car has been paired with a specific fob, it can only receive signals from the device. As a result, other fobs won't work with the vehicle even if they look the same. This helps to protect the integrity of the vehicle's computer system and prevent the use of unauthorized key fobs to gain control of the vehicle.
Most dealerships with newer cars will only deal with vehicles that have original fobs, or genuine replacements supplied 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 aftermarket fobs, usually those from older models with less sophisticated systems can be programmed without the need for a dealership.
