How to Program Keys For Cars
Locksmiths or automotive specialists are usually the ones who re-program car keys. They could take your old key and then use a special tool to program a brand new one for your car.
This involves changing the chip inside your replacement key to ensure that it matches the current settings of your vehicle. Some manufacturers make it simple to do, while others require a locksmith or dealer.
Self-programming
As the technology of cars has advanced throughout the years, ignition keys have also evolved as well. Gone are the days of simple mechanical-only keys that were made at an hardware store for less than $10. Modern models come with computers that are enhanced anti-theft protection. The cars require a transponder chip-integrated key to be programmed by a professional locksmith car dealer or mechanic for proper operation.
Professional locksmiths can perform a variety of different types of programming for keys to cars. Some are very complex and require sophisticated tools. These tools are not generally available to the public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other types of key programming can be carried out by anyone. They are typically done using the diagnostics port on the car, which is accessible with an instrument for programming keys. This method can be done by a locksmith who is trained using an online guide or the car's owner's manual.

Key Programmers
Modern cars require a key-programming method to initialize their vehicle's systems and then start the vehicle. In some instances keys must be set up by the dealer or auto locksmith. The key may not function correctly or will not start the vehicle in any way. The reason for this is that the new key hasn't been programmed into the vehicle's system - and this can be quite costly. This is why it's a great idea to always have two keys that work for a modern car and to have the replacement key programmed if required.
Keyprogrammers can recode the transponder chip on a new mechanical key or key fob. It also can clone the data of an existing key to make duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface for working with an immobilizer system.
There are many different types of keyprogrammers available on the market. They come in all shapes, sizes and colors. Some are affordable, while others are very advanced and can cost thousands of dollars. Some are designed for specific types of cars and can provide advanced diagnostics for the electronic systems of the car.

They are cheaper than visiting a dealership but they aren't inexpensive. Make sure you research the seller before purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, then it has a transponder inside of it. This is a little piece of plastic on the back of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then amplified by the specific antenna that is fitted around the barrel that controls your ignition in your vehicle. This allows the car's computer system to verify that the transponder chip inside the key is the correct one for the car you have.
This is what stops from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key also verifies that you are the genuine owner of the vehicle. This helps to prevent the possibility of theft from your vehicle.
Transponder keys look like regular keys made of metal but have a plastic cap. The chip is inside the plastic portion of the keys. There are a variety of cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe.
A circuit inside the induction coil emits an electrical signal when the transponder is inserted into ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as valid, it will disable vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder signal as the correct one, it will stop the engine from starting and will notify you by flashing its lights and sounding siren. This feature is intended to discourage people from trying to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal may still be able to get around this system employing a device designed to detect the signal.
As you can see there are quite number of advantages to having a transponder key. Every car owner should take this into consideration when they want to safeguard their investment and decrease the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, emit chirping sounds to aid in finding 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 with the car through radio frequencies which are transmitted via an antenna that is located in the center of the key. The communication is encrypted, which helps prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in different ways based on the model and brand of your vehicle. Some cars allow you to do this by yourself. However, the majority of modern 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, the microchip inside transmits a code to the car's receiver it is paired with. The receiver compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the data doesn't match, a chirping sound is heard and the car isn't able to operate.
After the car has been associated with a particular fob, it can only receive signals from that device. In turn, other fobs will not work with the vehicle even if they look the same. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of newer dealerships will only accept cars that have original fobs, or genuine replacements sold by the manufacturer. This is because the only place that has the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of dealers.
