Self-programming
As the technology of cars has advanced throughout the years, ignition keys have developed too. Gone are the days of simple mechanical keys that could be made at a hardware store for under $10. Newer models are equipped with computers that are enhanced anti-theft protection. In order to work properly, these cars require that a transponder chip key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
There are several types of car keys programming that can be performed by professional locksmiths. Certain are complicated and require specialized tools. 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 significant amount of time.
Other types of car key programming are much simpler and can be done by the average person. They are accomplished using the onboard diagnosis port, which can be accessed via a tool specifically designed for key-fob programming. This method can be done by a trained locksmith with the help of an online guide or the car's owner's manual.

Key Programmers
Modern vehicles frequently require a key programming procedure to start the system of the vehicle and allow the car to begin.

This is because the key hasn't yet been programmed into the vehicle's system. This could be costly. It's best to have two keys that are compatible for your modern car so you can program the replacement key whenever needed.
A keyprogrammer can recode the transponder chip on a new mechanical key or key fob. It can also clone the data of an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They come in all shapes, sizes and colors. Some are cheap, while others are very advanced and can cost thousands of dollars.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the past 20 years. It's a small plastic piece in 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 electro-magnetic field, the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is positioned around the ignition barrel of your vehicle. The computer system in the vehicle can then verify that the transponder chip of the key is the correct one for your vehicle.
This prevents the vehicle from being started through hot-wiring, or by tampering. The chip in the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys that are regular in shape like regular keys and have an outer layer of plastic. The chip is inside the plastic portion 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.
When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil will send out an electrical signal. The signal will be taken up by the chip, causing it to transmit a signal back to the car. If the onboard car computer recognizes this signal as being the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will notify you via flashing lights and a siren. This is designed to discourage people from attempting to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief could still evade 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. All car owners should consider this when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can be more than just a way to lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to aid in finding a car or turn on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna that is located in the middle of the key. This signal is encrypted to stop others from stealing or modifying the signal.
There are a few different ways to program a key fob based on your vehicle's make and model. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on your key fob it transmits a code to the car's radio that it is paired with. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then it opens or closes the car door. If the data does not match, the car will not be allowed to operate.
Once the car is linked with a specific fob it will only receive signals from that device. In i loved this , other fobs will not work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
Most newer car dealerships will only work with cars that have original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge which can only be obtained in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems -- can be programmed by customers without the need for an authorized dealer.
