Modern models come with computers that offer improved security against theft. The 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 keys programming that can be performed by professional locksmiths. Certain types are extremely complex and may require advanced tools. These tools are not accessible to the general public and are used only by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic skills and a significant amount of time.

Key Programmers
Modern vehicles frequently require a key programming procedure to initialize the vehicle's system and allow the car to start. In certain instances the key will have to be programmed by an auto locksmith or dealer. This is because the key could not work properly, or it will not start the vehicle in any way. This is because the key hasn't yet been programmed into the car's system. This could be costly. This is why it's a good idea to have two keys working for modern vehicles and have the replacement key programmed if necessary.
A keyprogrammer is a device that recodes the transponder chip into a new key fob or mechanical key. It can also clone the data from an existing key and allow duplicate keys to be created. 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 a computer. They also have a bidirectional interface for working with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They come in all sizes, shapes, and colors. Certain keyprogrammers are affordable, while others can cost thousands of dollar. Certain are designed for specific automobiles and provide advanced diagnostics of the car's electronic system.
If you want to program a new key to your vehicle, refer to the owner's manual to find out how to do it. Certain manufacturers have proprietary technology that guarantees that the dealership is the sole entity able to create new keys, however other manufacturers make it fairly easy for anyone to accomplish it themselves.
If you're not able to program a new key by yourself You can request the dealer to do it for you, but this can be expensive. You can also purchase a keyprogrammer from the internet. They're less expensive than visiting a dealership, but still not expensive. Make sure you research the seller before purchasing one - some are not reliable and could damage your car.
Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to determine if the transponder chip in the key is the right one for your specific vehicle.
This is what stops from modifying or hot-wiring the vehicle's ignition system to turn it on. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This helps to prevent car theft.
Transponder keys resemble normal keys but they have a plastic cap. The chip itself is housed within the plastic part of the key, and there are a few different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal to the vehicle. If the car's computer recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine, and will alert you with flashing lights and siren. This feature is designed to discourage people from trying to hack into the vehicle, but it is not a foolproof security measure. A skilled and determined thief could still evade this system with a specially designed device that intercepts the signal.
As you can see, there are quite a number of benefits to having a transponder key. All car owners should take this into consideration when they want to safeguard their investment and reduce theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding the car in a parking space, today's key fobs can also turn on the heated steering wheel or open all windows with just a single press. A lot of these features may seem convenient however they could make it harder for you to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are many ways to program a key fob depending on the make and model. It is possible to do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or a second fob.
When you hit the button on a key fob it transmits an informational code to the car's receiver that it is linked to. The receiver compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information does not match the signals, the car will not be allowed to run.
When a car is connected with a specific fob it will only receive signals from that device. As a result, other fobs will not work with the vehicle even though they look the same. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most dealerships with newer cars will only work with cars with original fobs, or genuine replacements offered by the manufacturer. It is because the only place with the knowledge to create a replacement fob is in the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need for a dealership.
