The latest models come with computer systems that are more secure against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic for proper operation.
Professional locksmiths can carry out various types of programming for keys to cars. automotive key programming are complex and require advanced tools. These tools are usually not accessible to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other types of programming for car keys are much simpler and can be done by anyone who is able to. They are typically accomplished by using the onboard diagnostics port that can be accessed using an instrument for programming keys.

Key Programmers
Modern vehicles often require a key programming process to initialize the vehicle's system and allow the car to start. In some instances the key needs to be programmed by an auto locksmith or a dealer. This is because the key might not function correctly, or it will not start the vehicle at all. The reason for this is that the new key has not been programmed into the vehicle's system - and this can be quite costly. It's best to have two keys that work for the modern automobile so that you can program the replacement key when needed.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It is also able to copy the information from an existing key and allow duplicate keys to be made. 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 a computer. They also have a bidirectional user interface to work with an immobilizer system.
There are a number of different types of keyprogrammers available that are available and they are available in all shapes and sizes.

These are cheaper than going to a dealer, but they're still not cheap. Before purchasing one do some research on the seller. Some aren't reliable and could damage your vehicle.
Transponder Chips
If your car was built within the past 20 years, it is likely that it has a transponder chip inside of it. This is a little plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your car.
This stops the vehicle from being started by hot-wiring or altering the key. The chip in the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have a plastic top. The chip itself is housed within the plastic part of the key, and there are a few different cuts that can be found on these keys: a regular cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine, and will warn you with flashing lights and siren. This feature is intended to discourage people from trying to hack into the vehicle, however it's not a 100% security measure. A skilled and skilled criminal could still evade this system by using a specific device that blocks the signal.
As you can see there are quite a number of benefits to having a transponder key. This is something that all car owners should think about if they want to protect their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also activate a heated steering wheel, or roll down all of the windows with a single push. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with each with the car via radio frequencies which are transmitted by a small antenna located in the middle of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. It is possible to do this yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
When you press a key fob's button, the microchip inside transmits an encoded code to the car's radio that it is paired with. 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 information does not match, the car will not be allowed to operate.
When a car is connected with a specific 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 is to safeguard the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need of a dealership.
