Self-programming
The ignition keys have developed as has the technology of cars. The days of simple mechanical-only keys that were made at the hardware store for less than $10. The newer models have computer systems that are more secure against theft. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, mechanic or dealer for proper operation.
Professional locksmiths are able to perform a variety of different types of programming for keys to cars. Some are very complex and may require sophisticated tools. These tools are not accessible to the general public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot time.
Other forms of programming car key s are much easier and can be performed by the average person. These are usually done by using the onboard diagnostics port which is accessible with an instrument for programming keys. A locksmith can perform this method with the help of a guide online and the owner's manual.

Key Programmers

Modern vehicles often require a key programming process to set up the car'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 might not work properly or start the vehicle in any way. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. It's best to have two keys that are compatible with your current car so you can program the replacement key if required.
Keyprogrammers are devices that can recode the transponder chip in an entirely new key fob or mechanical key. It can also clone the data of an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.
There are many different types of keyprogrammers on the market. They come in all sizes, shapes, and colors. Certain keyprogrammers are affordable, while others can cost thousands of dollar. Some are designed for specific types of vehicles and can provide advanced diagnostics for the car's electronic systems.
Check out the owner's manual to learn how to program the key to your vehicle. Certain manufacturers have proprietary technology that guarantees that the dealership is the only entity able to create new keys. However, other manufacturers make it fairly easy for anyone to accomplish it themselves.
If you're unable to program the new key on your own and you are unable to do it, then request your dealer to do it, however it will be very costly. You can also purchase a keyprogrammer from the internet. They are less expensive than going to a dealership, but still not expensive. Make sure you investigate the seller prior to purchasing one - some are not reliable and could damage your vehicle.
Transponder Chips
If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. It's the tiny piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own.
The chip emits an unintentional radio signal when it is activated by an electromagnetic field. The signal is absorbed by a special antenna that is attached to the barrel of ignition. This allows the computer in your vehicle system to verify that the transponder chip in the key is the right one for the car you have.
This is what stops doing hot-wiring or altering the ignition system of the vehicle to turn it on. The chip inside the car key confirms that the owner is the one who owns the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys resemble normal keys but they have caps made of plastic. The chip is contained within the plastic part of the key, and there are a few different kinds of cuts available on the keys: a cut laser cut (also called a sidewinder), or a Ford Tibbe key.
The circuit in the induction coil emits a signal when the transponder is put into ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as the right one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This feature is intended to discourage people from attempting to hack into the vehicle, however it is not a foolproof security measure. A skilled and committed thief might be able escape this security system by using a device that can take over the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all vehicle owners should think about if they want to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also start the vehicle remotely, emit chirping sounds to help locate cars or switch on the heated steering wheel. Many of these extra features might seem useful, but they can also make it more difficult to keep the keys to your car.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted by an antenna in the center of the key. The transmission is encrypted, which helps to keep others from stealing and re-transmitting the signal.
You can program a keyfob in various ways based on the model and make of your vehicle. You can sometimes do this yourself, however most modern cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press a key fob's button, the microchip inside transmits an encoded code to the car's radio that it is paired with. The receiver compared this information to the 'allowed' signals stored in the fob and then either locks or opens the door. If the information does not match, the car will not be allowed to run.
Once the car is linked with a particular fob, it will only receive signals from the device that is associated with it. As a result, other fobs won't be able to work with the vehicle even if they appear similar. This protects the integrity of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that can only be found in the dealer's service department. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
