The latest models are equipped with computer systems that are more secure against theft. These cars require a transponder-chip integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
Professional locksmiths can carry out various kinds of programming for keys for cars. Some are complex and require specialized tools. These tools aren't generally available to the public and are utilized only by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.

Key Programmers
Modern vehicles require a key-programming procedure to start the vehicle's system and to start the car. In certain instances the key needs to be programmed by an auto locksmith or dealer. This is because the key might not work properly, or it will not start the vehicle at all. This is because the key has not yet been programmed into the car's system. This can be costly. This is why it's a great idea to always have two working keys for a modern car and have the replacement key programmed if required.
Keyprogrammers are devices that recodes the transponder chip into the form of a new key fob or mechanical key. It can also clone the information from an existing key and allow duplicate keys to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with the computer, and they also have bidirectional interfaces to work with the immobilizer system.
There are a myriad of types of keyprogrammers on the market. They come in all shapes, sizes and colors. Some are affordable while others are sophisticated and could cost thousands of dollars.

Another option is to purchase an online keyprogrammer. They are cheaper than visiting a dealer however, they aren't expensive. Make sure you investigate the seller prior to purchasing one. Some aren't reliable and could harm your vehicle.
Transponder Chips
If your car was built within the last 20 years, then it contains a transponder chip within of it. It's the tiny piece of plastic in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to the vehicle you own.
When it is activated by an electromagnetic field, the chip emits a low level signal. The signal is then absorbed by a special antenna attached to the barrel of ignition. This allows the vehicle's computer system to confirm that the transponder chip in the key is the right one for the car you have.
This is what prevents from modifying or hot-wiring the ignition system of your vehicle to turn it on. The chip inside the key verifies that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys appear like regular keys made of metal but they have a plastic cap. The chip is contained inside the plastic portion of the key and there are a few different cuts that can be found on these keys: a regular standard cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
The circuit in the induction coil will emit signals when the transponder is inserted into ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer inside the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.
If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine and alert you with flashing lights and an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.
As you can see, there are quite a number of benefits to having transponder keys. Every car owner should take this into consideration if they wish to protect their investment and decrease the chance of theft.
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 keys of today can also switch on the heated steering wheel or roll down all of the windows with a single press. These extra features could make it difficult to find your car keys.
Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent through a small antenna located inside the middle of the key. This signal is encrypted to block other key fobs from stealing or modifying the signal.
There are many ways to program a key fob, based on your vehicle's model and make. It is possible to do this yourself, however most modern automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press a key fob's button the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compares the information with the permitted signals stored on the key fob and then it opens or closes the car door. If the data does not match the fob's information, the car won't be allowed to drive.
Once the car has been connected to a specific fob, it only accepts signals from that device. Other fobs will not work with the car, even if they look similar. This helps to protect the integrity of the car's computer system and to prevent unauthorised key fobs from taking control over the vehicle.
The majority of newer dealerships will only work with cars with original fobs, or genuine replacements supplied by the manufacturer. It is because the only place with the knowledge to create the replacement fob is the service department of the dealer. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
