The latest models are equipped with computers with improved anti-theft protection. These cars require a transponder-chip integrated key to be programmed by a professional locksmith, car dealer or mechanic for proper operation.
There are several types of car key programming that can be done by professional locksmiths. Certain types are more complex and require sophisticated tools. These tools are not accessible to the general public and are used only by professionals. This type of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic knowledge and a significant amount of time.

They are accomplished with the onboard diagnostic port, which is accessible by a specific tool for key-fob programming.

Key Programmers
Modern vehicles require a key-programming process to initialize their vehicle's systems and to start the car. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key may not work correctly or will not start the car in any way. This is because the key has not yet been programmed into the vehicle's system. This can be costly. It is best to have two keys that work for the modern automobile so that you can program the replacement key if needed.
A keyprogrammer can recode a transponder chip on an entirely new mechanical key or key fob. It can also 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 interface to work with an immobilizer system.
There are many different kinds of keyprogrammers on the market, and they come in a variety of sizes and shapes. Some are cheap, while others are very sophisticated and can cost thousands of dollars. Certain models are specifically designed for certain types of cars, and they can even provide advanced diagnostics for the electronic systems of the car.

They are less expensive than going to a dealership but they aren't inexpensive. Before you purchase one make sure you research the seller. Some aren't trustworthy and could cause damage to your vehicle.
Transponder Chips
Transponder chips can be found in cars manufactured in the last 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This prevents the vehicle from being started by hot-wiring or altering the key. The chip in 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 keys, but with a plastic top. The chip is inside the plastic part of these keys. There are several different cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and Ford Tibbe.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer onboard the car is able to recognize the signal as being correct it will turn off the car immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from running and will alert you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it isn't an absolute security measure. A determined and skilled thief could still bypass this system with a specially designed device that blocks the signal.
As you can see, there are quite a few advantages to getting a transponder key. This is something that all car owners should consider if are looking to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding the car, or switch on the heated steering wheel. These extra features could make it difficult to find your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted by an antenna that is located in the middle of the key. The transmission is encrypted, which helps to stop others from stealing and replicating the signal.
You can program a keyfob in different ways based on the make and model of your vehicle. Some cars allow you to do this yourself. However, the majority of modern models require you to visit an expert locksmith or dealer for them program a replacement key fob or additional one.
When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then opens or locks the car's door. If the information doesn't match, the car will not be allowed to operate.
After the car has been connected to a specific fob, it will only accept signals from that device. This means that other fobs won't work with the vehicle even though they appear similar. This ensures the security of the computer system that runs the vehicle and stops unauthorized key fobs gaining control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security expertise which can only be obtained in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
