Newer models are equipped with computers that are enhanced anti-theft protection.

These tools aren't generally available to the public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.

This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to have two keys that work for a modern automobile and have the replacement key programmed if necessary.
A keyprogrammer is a tool that recodes the transponder chip on a new mechanical or key fob key. It can also clone the information from an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.

Transponder Chips
If your car was manufactured within the last 20 years, it is likely that it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from starting by hot-wiring or altering the key. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys appear like regular keys made of metal but they have caps made of plastic. The chip is located inside the plastic part of the keys. There are various cuts that are a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit inside the induction coil will emit a signal when the transponder is inserted into an ignition barrel. The signal will then get received by the chip, causing it to send a signal back to the car. If the car's computer recognizes this signal as the correct one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system by using a specific device that blocks the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all vehicle owners should consider if want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find the car in a parking space keys of today can also turn on a heated steering wheel or open all windows with a single press. A lot of these additional features may seem convenient, but they can also make it more difficult to keep the track of your car keys.
Key fobs use radio frequencies to communicate with one another and with the car. These frequencies are sent through a small antenna located within the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. You may be able to do it yourself, but the majority of newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press the button on a key fob, the microchip transmits signals to the receiver inside the car with which it is linked. The receiver compared the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the data does not match the fob's information, the car won't be allowed to drive.
When a car is connected with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even if they look identical. This helps to protect the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control over the vehicle.
The majority of newer dealerships will only deal with cars that have original fobs, or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. Some aftermarket fobs, usually those for older models with less sophisticated systems can be programmed without the need for a dealer.
