In order to work properly, these cars require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or a car dealer/mechanic.
Professional locksmiths can perform a variety of different types of programming for keys to cars. Some are very complex and may require advanced tools. These tools aren't generally available to the public and are used only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic expertise and a lot of time.
Other types of key programming can be done by anyone. They can be done by using the onboard diagnostic port, which is accessible by a specific tool for key fob programming. Locksmiths can execute this method with the assistance of an online guide and the owner's manual.

Key Programmers

The key might not function properly or it may not even start the car at all. The reason is because the new key has not been programmed to the car's system - and this can be very costly. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key if required.
A keyprogrammer can recode the transponder chip on the new mechanical key or key fob. It is also able to copy the data of an existing key in order to create 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 user interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap while others could cost thousands of dollars.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured within the past 20 years. This is the little plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your car.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. The signal is taken up by an antenna attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for your particular car.
This is the reason why hot-wiring or tampering with the vehicle's ignition system to get it started. The chip inside the key also confirms that you are the legal owner of the vehicle. This can reduce car theft.
Transponder keys appear like normal keys, but with a plastic cap. The chip is contained within the plastic part of the key, and there are a few different types of cuts on these keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key.
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 absorbed by the chip, causing it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as valid, it will disable vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal can still get around this system by using a specific device that detects the signal.
As you can see, there are quite a few advantages to getting a transponder key. Every car owner should consider this if they wish to protect their investment and reduce 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 vehicle remotely, make chirping noises to help locate cars, or switch on the heated steering wheel. These additional features could make it difficult to locate your car keys.
Key fobs use radio frequencies to communicate with each other and with the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
There are a few different ways to program a key fob, based on the vehicle's model and make. You may be able to do it yourself, but the majority of newer cars require that you visit an expert locksmith or dealer to program a replacement or a second fob.
When you press the button on a key fob, the microchip sends signals to the receiver in the vehicle 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 information does not 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. Other fobs won't work with the car, even if they appear like. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control over the vehicle.
The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements supplied by the manufacturer. It is because the only place that has the expertise to prepare the replacement fob is a dealer's service department. Some fobs from the aftermarket, especially those from older models with less sophisticated systems can be programmed without the need for a dealer.
