The latest models are equipped with computers with improved anti-theft protection. In order to work properly, these cars require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
There are several kinds of car key programming that can be accomplished by professional locksmiths. Some are complex and require advanced tools. These tools are generally not available to the general public and are used only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.
Other kinds of car key programming are much easier and can be done by the average person. These are done with the onboard diagnostic port, which can be accessed with a special tool for key-fob programming. This procedure can be carried out by a locksmith who is trained with the help of an online guide or the vehicle's owner's manual.

Key Programmers
Modern cars require a key-programming process to start the vehicle's system and to start the car. In some instances the key needs to be programmed by an auto locksmith or a dealer. This is because the key may not work properly or start the vehicle at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. This is why it's a good idea to always have two keys that work for a modern automobile and to have the replacement key programmed when needed.
Keyprogrammers can recode a transponder chip on the new mechanical key or key fob. reprogram car key can also clone data from an existing key to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They are available in a variety of sizes, shapes and colors. Some keyprogrammers are cheap and others may cost thousands of dollars. Certain are designed for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.

They are cheaper than going to a dealership, but still not inexpensive. Be sure to look up the seller before buying one. Some aren't reliable and could harm your car.
Transponder Chips
If your car was manufactured within the last 20 years, chances are it has a transponder inside of it. This is a little plastic thing in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted 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 right one for your vehicle.
This is the reason why from modifying or hot-wiring the ignition system of your vehicle to start it. The chip in the car key confirms that the owner is the person who owns the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is housed within the plastic part of the key and there are a few different types of cuts on these keys: a regular cut laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer onboard the car recognizes the signal as correct, it will disable vehicle immobilizer so that the engine can start.
If the car does not recognize the transponder signal as the correct one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and determined thief could still be able to get around this system using a special device to intercept the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should think about if they want to protect their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also turn on a heated steering wheel or open all windows with a single push. These extra features could make it difficult to find your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent via a small antenna that is located in the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and replicating the signal.
There are several ways to program a key fob based on your vehicle's make and model. Certain cars let you do this by yourself. However, the majority of newer models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press a key fob's button the microchip inside sends a code to the car's receiver that it is linked to. The receiver then compares this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information does not match, the car will not be allowed to run.
Once the car is linked with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, even if they look similar. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control of it.
Most newer car dealerships will only accept vehicles that have original fobs, or genuine replacements offered by the manufacturer. This is because the only place that has the experience to design a replacement fob is in the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by customers without the need for dealers.
