The ignition keys have developed in tandem with the advancements in car technology. Gone are the days of simple mechanical keys that could be made at an hardware store for less than $10. Modern models come with computers that offer improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith car dealer or mechanic for proper operation.
There are a few different types of car keys programming that can be done by professional locksmiths. Certain types are more complex and require sophisticated tools. These tools are usually not available to the general 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 forms of car key programming are much simpler and can be performed by the average person. They can be done by with the onboard diagnostic port, which is accessible with a special tool for key-fob programming. This method can be done by a trained locksmith using an online guide or the car's owner manual.

You can be certain that the new key will work and is programmable for your vehicle. If not, you'll have to pay the dealership for replacement keys and programming services.
Key Programmers
Modern cars require a key-programming method to initialize their vehicle's systems and to start the car. In some instances the key needs to be set up by the auto locksmith or dealer. The key may not work properly or not start the car at all. This is because the key has not yet been programmed into the car's system. This can be expensive. This is why it's a great idea to always have two keys working for a modern car, so you can get the replacement key programmed when required.
Keyprogrammers are devices that recodes the transponder chip into an entirely new key fob or mechanical key. It can also clone data from an existing key to make duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are a variety of keyprogrammers available on the market. They are available in a variety of sizes, shapes and colors. Certain keyprogrammers are affordable, while others could cost thousands of dollars. Certain models are specifically designed for vehicles and can provide advanced diagnostics of the car's electronic system.
If you want to program the new key into your vehicle, refer to the owner's manual to learn how to do it. Certain manufacturers have proprietary software that allows only dealers to create new keys. Other manufacturers make it easy for anyone to complete.
If you are unable to program the new key yourself or by yourself, you can request your dealer to do it, however it will be very costly. Another option is to purchase a keyprogrammer online. These are cheaper than visiting a dealership however they're not cheap. Before you purchase one do some research on the seller. Some aren't reliable and could damage your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, chances are it has a transponder inside of it. This is the little 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 fitted around the barrel that controls your ignition in your car. The computer system of the vehicle can then verify that the chip in the key's transponder is the correct one for your car.
This prevents the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key also proves that you are the genuine owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys and have a plastic top. The chip is housed within the plastic part of the key, and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will disable the vehicle immobilizer and allow the engine to start.
If the vehicle does not recognize the transponder signal as the proper one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is intended to discourage people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief can still get around this system with a specially designed device that detects the signal.
It is evident that the transponder is an excellent option. This is something that all vehicle owners should consider if they want to protect their investment and minimize 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 the car in a parking lot, today's key fobs can also switch on a heated steering wheel, or open all windows with a single button click. These extra features could make it difficult to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies which are transmitted via a small antenna located in the center of the key. The signal is encrypted to block other key fobs from stealing or modifying the signal.
There are a few different ways to program a key fob depending on the vehicle's make and model. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit a professional 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 an informational code to the car's receiver it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car's doors. If the information isn't in line, a chirping sound is heard and the car isn't able to function.
Once the car has been connected to a specific fob, it only accepts signals from the device. Other fobs will not work with the car, even if they appear identical. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it.
Most newer car dealers will only work on a car with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise that can only be found in the dealer service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for an authorized dealer.
