The latest models are equipped with computer systems that are more secure against theft. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic for proper operation.
Professional locksmiths can perform various types of programming for car keys. Certain types are extremely complex and require sophisticated tools. These tools are generally not available to the general public and are only used 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 key programming can be done by anyone. These are usually done by using the onboard diagnostics port, which can be accessed with a special key-fob-programming tool. This procedure can be carried out by a professional locksmith with the help of an online guide or an owner manual.

This is because the key might not function properly, or it will not start the vehicle in any way. This is because the new key has not been programmed to the automobile's system - and this can be quite costly. This is why it's a good idea to have two working keys for modern vehicles and to have the replacement key programmed when needed.
A keyprogrammer is a device which can reprogram the transponder chip in an entirely new mechanical or key fob key. It is also able to copy the data of an existing key to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with a computer. They also feature a bidirectional user interface that works with an immobilizer system.
There are a variety of keyprogrammers on the market. They come in all sizes, shapes, and colors. Some are inexpensive and others could cost thousands of dollars.

Transponder Chips
If your car was built in the past 20 years, chances are it has a transponder inside of it. It's the small piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal is then received by a specific antenna that is attached to the ignition barrel. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This is the reason why from modifying or hot-wiring the ignition system of the vehicle to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys appear like regular metal keys, but with caps made of plastic. The chip is contained within the plastic part of the key, and there are different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil emits a signal when the transponder is placed in the ignition barrel. The signal is absorbed by the chip, which sends a signal to the vehicle. If the computer onboard the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and will notify you via flashing lights and an alarm. This system is designed to deter people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and committed thief might be able escape this security system by using a device that can detect the signal.
programming car keys is evident that the transponder is an excellent option. This is something that all vehicle owners should consider if 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 noises to aid in finding a car in a parking lot Key fobs today can also switch on a heated steering wheel, or roll down all windows with a single press. 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. The frequencies are transmitted via a small antenna that is located within the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.
There are many ways to program a key fob, based on the vehicle's model and make. Certain models allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or additional one.
When you press the button on a key fob the microchip transmits a signal to the receiver in the car with which it is linked. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car's door. If the data does not match the fob's information, the car won't be allowed to run.
Once the car is associated with a particular fob, it will only accept signals from that device. Other fobs will not work with the car, despite the fact that they look like. This protects the integrity of the computer system in the car and blocks unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only work with vehicles that have original fobs or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security skills which can only be obtained in the dealer service department. Some aftermarket fobs, usually ones for older models with less sophisticated systems, can be programmed without the need for a dealer.
