How to Program Keys For Cars
Reprogramming the car key typically is the responsibility of a locksmith or automotive specialist. They can take your old working key and use a special tool to program a new key for your car.

Self-Programming
The ignition keys have developed along with the car technology. The days of the simple mechanical keys you could make at a hardware shop for less than $10 have gone. Modern models come with computers that offer improved security against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith, mechanic or dealer to function properly.
Professional locksmiths can perform various kinds of programming for keys to cars. Certain types are more 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 referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other kinds of programming car keys are much simpler and can be performed by anyone who is able to. They are typically accomplished by using the diagnostics port on the car, which can be accessed with the key-fob-programming device. Locksmiths can carry out this procedure with the help of an online guide and the owner's manual.
Professional locksmiths can program a new or replacement car key fob in a short time. This is the best option for car owners since they can provide a complete range of services. They can offer a competitive cost and peace of mind knowing that the replacement key is guaranteed to work.

You can be sure the new key works and is programmable for your vehicle. You'll need to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern cars require a key-programming process to initialize their vehicle's systems and start the car. In many cases the key needs to be programmed by the dealer or an auto locksmith. This is because the key might not function correctly or start the car in any way. This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key when needed.
A keyprogrammer can recode a transponder chip on an entirely new mechanical key or key fob. It is also able to clone information from an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers, and they also have a bidirectional interface for working with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes, and colors. Some are inexpensive, while others could cost thousands of dollars. Certain are designed for specific automobiles and provide advanced diagnostics of the car's electronic system.
If you're looking to program a new key to your vehicle, consult the owner's manual to find out the procedure. Certain manufacturers employ proprietary software that allows only dealers to create new keys. Other manufacturers make it simple for anyone to do.
If you are not able to program the new key by yourself or by yourself, you can ask your dealer to do it, however it will cost you a lot. Another option is to buy a keyprogrammer online. These are less expensive than going to a dealer however, they're not cheap. Be sure to investigate the seller prior to purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured in the past 20 years, it is likely that it contains a transponder chip within of it. This is a little plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with an individual code for your specific vehicle.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets taken up by the antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to determine if the transponder chip that is in the key is the correct one for your specific vehicle.
This is what stops doing hot-wiring or altering the vehicle's ignition system to turn it on. The chip in the key also proves that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is housed inside the plastic portion of the key and there are different kinds of cuts available on these keys: a regular cut, a laser cut (also called a sidewinder) or 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 onboard car computer recognizes this signal as the correct one, it will turn off the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as a valid signal, it won't start the engine and warn you with flashing lights and siren. This feature is intended to deter people from trying to hack into the vehicle, but it's not a 100% security measure. A skilled and determined thief could still be able to escape this security system by using a special device to take over the signal.
As you can see, there are quite a number of benefits to having a transponder key. This is something that all car owners should consider if want to protect their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making noises to aid in finding the car in a parking space, today's key fobs can also switch on a heated steering wheel or open all windows with a single press. Many of these extra features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs use radio frequencies to connect with one another and the car. These frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps prevent others from intercepting and retransmitting the signal.
There are car key programming to program a key fob depending on the model and make. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or additional fob.
When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle with which it is paired. The receiver compared this information to the 'allowed' signals stored on the fob and either opens or closes the door. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
After the car has been connected to a specific fob, it will only accept signals from that device. As a result, other fobs won't be able to work with the vehicle even if they look the same. This is to safeguard the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
The majority of newer dealers will only work on a car with original fobs or genuine replacements sold by the manufacturer. It is because the only place with the expertise to prepare an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems can be programmed by consumers without the need for dealers.
