Self-programming
As car technology has evolved over time, the ignition keys have developed as well. The days of basic mechanical keys you could make at a hardware store for less than $10 are gone. Modern models come with computers that have improved anti-theft protection. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
There are many types of car key programming that can be done by professional locksmiths. Certain are complicated and require advanced tools. These tools are not generally accessible to the general public and are utilized only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.
Other forms of programming for car keys are much easier and can be accomplished by anyone who is able to. They are typically accomplished by using the onboard diagnostics port that can be accessed using the key-fob-programming device. This method can be performed by a locksmith who is trained with the help of an online guide or the car's owner manual.

You can be certain that the new key will work and is compatible with your car. In the event that it doesn't, you'll need to pay the dealer for replacement keys and programming services.
Key Programmers
Modern vehicles require a key-programming process to initialize their vehicle's systems and to start the car. In some cases the key will have to be programmed by an 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 vehicle's system. This can be costly. This is why it's a great idea to always have two working keys for modern vehicles and to have the replacement key programmed if needed.
Keyprogrammers can recode a transponder chip on an entirely new mechanical key or key fob. It can also clone information from an existing key to make duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors. Some keyprogrammers are cheap, while others may cost thousands of dollars. Certain models are specifically designed for certain types of cars and can provide advanced diagnostics for your car's electronic systems.
Consult your owner's guide to learn how to program the key to your vehicle. Certain manufacturers have proprietary technology that ensures the dealership is the only entity that can create new keys, but other manufacturers make it easy for anyone to accomplish it themselves.
If you're unable to program a new key yourself or ask the dealership to program it for you, however it will cost a lot. You can also buy a keyprogrammer from the internet. These are less expensive than going to a dealer, but they're still expensive. Make sure you investigate the seller prior to purchasing one. Some aren't reliable and could damage your vehicle.
Transponder Chips
If your car is made within the past 20 years, it is likely that it has a transponder inside of it. It's a small plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then absorbed by a special antenna that is attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip inside the key is the right one for the car you have.
This is what prevents from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the key also confirms that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are different types of cuts on these keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit inside of the induction coil sends out an electrical signal. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer inside the car recognizes the signal as being correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the right one, it will stop the engine from running and will notify you by flashing its lights and sounding a siren. This feature is designed to deter people from trying to hack into the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system by using a specific device that intercepts the signal.
As you can see, there are quite a number of benefits to having transponder keys. All car owners must take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate the car in a parking lot, today's key fobs can also turn on the heated steering wheel or open all windows with a single button click. Many of these extra features may appear convenient, but they can also make it harder for you to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with one another and with the car. These frequencies are sent by a small antenna inside the middle of the key. This communication is encrypted, which helps keep others from stealing and replicating the signal.
You can program a keyfob in different ways based on the model and make of your vehicle. Some cars allow you to do this yourself. However, the majority of newer models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one.
When you press a key fob's button the microchip inside sends an informational code to the car's receiver it is paired with. The receiver compares this information to the 'allowed' signals stored inside the fob, and either opens or closes the door. If the data does not match, the car will not be allowed to run.
Once the car is associated with a particular fob, it will only accept signals from that device. This means that 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 car and blocks unauthorized key fobs gaining control of it.
programming car keys of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. The reason for this is that the only place that has the experience to design a replacement fob is in the service department of a dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
