Modern models come with computers that have improved anti-theft protection. These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer to function properly.
There are a few different kinds of car key programming that can be performed by locksmiths who are professionals. Certain are complicated and require sophisticated tools. These tools are generally not accessible to the general public and are used only by professionals. This kind of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other types of key programming can be carried out by anyone. They are typically done using the onboard diagnostics port which is accessible with a special key-fob-programming tool. This method can be done by a trained locksmith with the help of an online guide or an owner's manual.

Modern cars typically require a key programming process to set up the car's system and allow the car to begin. In some instances the key needs to be programmed by an auto locksmith or dealer. The key may not function correctly or will not start the vehicle at all. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to have two working keys for a modern car and to have the replacement key programmed if required.
A keyprogrammer can reprogram the transponder chip on an entirely new mechanical key or key fob. It also can clone information from an existing key in order 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 the computer, and they also have an interface that works bidirectionally with the immobilizer system.
There are a number of different kinds of keyprogrammers that are available and they come in all shapes and sizes.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the small piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets amplified by the specific antenna that is attached to the ignition barrel of your vehicle. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from starting by either hot-wiring or by altering the key. The chip in the key also verifies that you are the legitimate owner of the vehicle. This can help to reduce the possibility of theft from your vehicle.
Regular transponder keys are designed like regular keys, but with a plastic top. The chip itself is housed inside the plastic portion of the key, and there are a few different types of cuts on these keys: a regular cut laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted 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 to the vehicle. If the computer inside the car is able to recognize the signal as being correct, it will disable vehicle immobilizer so that the engine can start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and notify you via flashing lights and siren. This feature is designed to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief might be able bypass this system by using a device that can detect the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if want to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking lot keys of today can also turn on a heated steering wheel or roll down all windows with a single button push. These extra features can make it difficult to locate your car keys.
Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are transmitted by a small antenna inside the middle of the key. The communication is encrypted, which helps stop others from stealing and retransmitting the signal.
Keyfobs can be programmed in different ways based on the make and model of your vehicle. You may be able to do it yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits a signal to the receiver inside the vehicle that it is paired. The receiver then compares the data with the permitted signals stored on the key fob and then opens or locks the car's door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car has been associated with a particular fob, it can only receive signals from the device. Other fobs won't work with the car, even if they look like. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by consumers without the need for dealers.
