Self-programming
As technology for cars has improved over the years, the ignition keys have evolved too. The days of basic mechanical keys you could make at the hardware shop for less than $10 are gone. Newer models are equipped with computers that are enhanced security against theft. In order to work correctly, these vehicles require that a transponder chip-integrated key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
Professional locksmiths can perform a variety of different types of programming for car keys. Some are extremely complicated and may require sophisticated tools. These tools are not accessible to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of programming for car keys are much simpler and can be done by anyone who is able to. These are done using the onboard diagnostic port, which can be accessed by a specific tool for key-fob programming. Locksmiths can carry out this procedure with the help of an online guide and the owner's manual.

Key Programmers
Modern cars require a key-programming process to start the vehicle's system and then start the vehicle. In some cases the key needs to be programmed by an auto locksmith or dealer. This is because the key could not function correctly, or it will not start the vehicle at all. This is because the new key hasn't been programmed to the automobile's system. This can be quite expensive. It's best to have two keys that work for the modern automobile so that you can program the replacement key if needed.
A keyprogrammer is a tool which can reprogram the transponder chip on a new key fob or mechanical key. It is also able to clone data from an existing key and allow duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with computers as well as a bidirectional interface for working with the immobilizer system.
There are many different kinds of keyprogrammers that are available and they come in a variety of shapes and sizes. Some keyprogrammers are cheap and others can cost thousands of dollar. Some are specifically designed for certain types of vehicles and can provide advanced diagnostics for your electronic systems of the car.

They're less expensive than going to the dealership, but they're still not cheap. Before buying one, do some research on the seller. Some aren't reliable and could cause damage to your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, then it has a transponder inside of it. This is the little plastic piece inside the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is taken up by an antenna attached to the barrel of ignition. This allows the car's computer system to confirm that the transponder chip inside the key is the correct one for your specific vehicle.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip in the key also verifies that you are the legal owner of the vehicle. car key programming will help reduce car theft.
Transponder keys resemble regular metal keys, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil will emit signals when the transponder is put into an ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer on the car detects this signal as the right one, it will turn off the vehicle immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will stop the engine from running and will notify you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an absolute security measure. A skilled and determined thief could still bypass this system by using a specific device that detects the signal.
As you can see, there are quite a number of benefits to having transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and decrease the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car from a distance, make chirping sounds to help locate a car, or switch on the heated steering wheel. These extra features can make it difficult for you to find your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via an antenna that is located in the center of the key. This signal is encrypted to stop others from stealing or stealing the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. Certain models allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or additional one.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver it is linked to. The receiver compared the information with the permitted signals stored in the key fob and then locks or opens the car's door. If the information does not match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob it will only receive signals from that device. In turn, other fobs will not work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. Some fobs from the aftermarket, especially ones for older models with less advanced systems can be programmed with out the need for a dealer.
