As technology for cars has improved throughout the years, ignition keys have evolved as well. Gone are the days of simple mechanical-only keys that could be manufactured at an hardware store for less than $10. The latest models are equipped with computers with improved anti-theft protection. To function properly, these cars require that a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
There are a few different types of car keys programming that can be accomplished by professional locksmiths. Certain types are extremely complex and require sophisticated tools. These tools are not generally available to the public and are only used by professionals. This kind of programming for car keys is referred to as EEPROM Programming and requires soldering, electronic knowledge and a significant amount of time.
Other types of programming car keys are much simpler and can be accomplished by anyone who is able to. These are done using the onboard diagnostic port, which is accessible by a specific tool for key fob programming.

You can be certain that the new key will work and is programmed for your car. If not, you'll have to pay the dealership for replacement keys and programming services.
Key Programmers
Modern vehicles frequently require a key programming procedure to set up the car's system and allow the vehicle to start. In certain instances the key needs to be programmed by an auto locksmith or a dealer. This is because the key might not work properly or start the vehicle in any way. The reason is because the new key hasn't been programmed to the car's system. This can be very costly. It's best to have two keys that are compatible with your current car so you can program the replacement key if needed.
A keyprogrammer is a tool which can reprogram the transponder chip into a new mechanical or key fob key. It is also able to clone information from an existing key, allowing duplicates to be created. These are handheld devices that connect to the car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer and also provide bidirectional interfaces to work with the immobilizer system.
There are many different types of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Some are inexpensive, while others are very advanced and could cost thousands of dollars. Some are designed for specific types of vehicles, and they can even provide advanced diagnostics for your electronic systems of the car.
Refer to the owner's manual of your vehicle to learn how to program a key for your vehicle. Certain manufacturers employ proprietary technology that ensures the dealership is the only entity able to create new keys, but other manufacturers make it simple for anyone to do it themselves.

They're less expensive than visiting a dealer however, they aren't inexpensive. Make sure you look up the seller before buying one. Some aren't reliable and can damage your car.
Transponder Chips
If your car is made within the last 20 years, chances are it has a transponder chip inside of it. It's a tiny plastic piece inside the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When activated by an electro-magnetic field, the chip emits a low level signal. This signal then gets absorbed by the special antenna that is positioned around the ignition barrel of your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the correct one for your particular car.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the genuine owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular keys, but with a plastic top. The chip itself is housed inside the plastic portion of the key and there are different types of cuts on the keys: a cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will then get absorbed by the chip and cause it to transmit a signal to the car. If the computer on the car detects this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to begin.
If the vehicle does not recognize the transponder signal as the correct one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to deter people from trying to alter the vehicle, however it isn't a foolproof security measure. A skilled and determined thief can still get around this system using a special device that detects the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all car owners should think about if they want to protect their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding a car in a parking lot, today's key fobs can also switch on a heated steering wheel or roll down all windows with just a single press. Many of these extra features might seem useful but they could make it harder for you to keep the track of your car keys.
Key fobs utilize radio frequencies to communicate with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. This communication is encrypted to stop others from intercepting or replicating the signal.
You can program a keyfob in a variety of ways depending on the model and brand of your car. Certain cars let you do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob or additional one.
When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then opens or locks the car's door. If the information does not match the fob's information, the car won't be allowed to drive.
Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. As a result, other fobs will not work with the vehicle even though they have the same appearance. This is to safeguard the integrity of the car's computer system, and also to stop the use of unauthorized key fobs to gain control of the vehicle.
Most dealerships with newer cars will only accept cars with original fobs or genuine replacements supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise 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 consumers without the need for a dealership.
