The ignition keys have changed as has the technology of cars. The days of the simple mechanical keys that you could make at a hardware store for less than $10 are long gone. Modern models come with computers that offer improved security against theft. These cars require a transponder-chip integrated key to be programmed by a professional locksmith, car dealer or mechanic in order to function properly.
There are many types of car key programming that can be performed by locksmiths who are professionals. Some are complex and require sophisticated tools. These tools aren't usually available to the public and are used only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a lot of time.
Other kinds of key programming can be performed by anyone. These are usually done by using the onboard diagnostics port, which can be accessed with an instrument for programming keys. Locksmiths can execute this method with the assistance of an online guide as well as the owner's manual.

Key Programmers
Modern vehicles require a key-programming procedure to start the vehicle's system and start the car. In some instances the key needs to be programmed by an auto locksmith or a dealer. This is because the key could not function 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 can be expensive. This is why it's a good idea to always have two working keys for a modern car, so you can get the replacement key programmed when required.
A keyprogrammer is a tool which can reprogram the transponder chip on the form of a new mechanical or key fob key. It also can clone data 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 are equipped with diagnostic software that allows them to communicate with a computer. They also have a bidirectional interface to work with an immobilizer system.
There are a number of different kinds of keyprogrammers on the market and they come in all shapes and sizes. Some are cheap, while others are very sophisticated and could cost thousands of dollars. Certain models are specifically designed for automobiles and provide advanced diagnostics of the car's electronic system.

Transponder Chips
If your car was built in the past 20 years, chances are it has a transponder inside of it. It's a tiny piece of plastic on the back of your key that contains an RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the barrel of ignition. The computer system in the vehicle is then able to verify that the key's transponder chip is the correct one for your car.
This is the reason why from modifying or hot-wiring the ignition system of your vehicle to start it. The chip inside the key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal, but with a plastic cap. The chip is housed inside the plastic portion of the key and there are different kinds of cuts available on these keys: a regular standard 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 a signal. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
If see here now doesn't recognize the transponder as the correct signal, it won't start the engine and will notify you via flashing lights and an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still be able to escape this security system by using a special device to detect the signal.
As you can see there are quite number of benefits to having transponder keys. All car owners should consider this in order to safeguard their investment and reduce theft risk.
Key Fobs
Key fobs today offer more than locking and unlock doors. They can also start your car remotely, make chirping noises to help locate the car, or switch on the heated steering wheel. These additional features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are many ways to program a key fob, based on the make and model. Certain models allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press the button on a key fob, the microchip transmits an indication to the receiver in the car that it is paired. The receiver then compares this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
Once the car is paired with a specific fob, it will only accept signals from that specific device. In turn, other fobs won't work with the vehicle, even though they look the same. This ensures the security of the computer system of the car and prevents unauthorised key fobs from taking control over it.
Most dealerships with newer cars will only accept cars that have original fobs, or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge which can only be obtained in the dealer service department. Certain aftermarket fobs, typically ones for older models with less advanced systems can be programmed with out the need for a dealer.
