The cars require a transponder chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic in order to function properly. Professional locksmiths can perform various kinds of programming for keys for cars. Certain types are more complex and require sophisticated tools. These tools aren't generally available to the public and are used only by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time. Other kinds of key programming can be done by anyone. These are done using the onboard diagnosis port, which is accessible via a tool specifically designed for key-fob programming. This method can be performed by a professional locksmith using an online guide or the vehicle's owner manual.

Key Programmers Modern vehicles require a key-programming method to initialize their vehicle's systems and start the car. In some instances the key will have to be programmed by an auto locksmith or dealer. The key might not function properly or it may not even start the car in any way. The reason for this is that the new key has not been programmed to the car's system – and this can be quite costly. It is best to have two keys that are compatible with your current car so you can program the replacement key whenever required. Keyprogrammers can recode the transponder chip on an entirely new mechanical key or key fob. It can also clone the data from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that enables them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system. There are many different kinds of keyprogrammers on the market and they come in all shapes and sizes. Certain keyprogrammers are affordable while others could cost thousands of dollars. Certain models are specifically designed for certain kinds of vehicles and can offer advanced diagnostics for the car's electronic systems. If you're interested in programming an entirely new key for your vehicle, check the owner's manual for instructions on the procedure. Some manufacturers use proprietary technology that ensures the dealership is the only entity that can make new keys. However, other manufacturers make it easy for anyone to do it on their own. If you are unable to program a new key on your own or ask the dealership to program it for you, but this can be expensive. You can also buy an online keyprogrammer. They are cheaper than going to a dealership however, they aren't cheap. Make sure you look up the seller before buying one – some are not reliable and could damage your vehicle. Transponder Chips Transponder chips are likely to be found in cars manufactured within the last 20 years. It's a small piece of plastic on the back of your key which contains an 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. The signal is absorbed by a special antenna that is attached to the barrel of ignition. The computer system in the vehicle can then verify that the chip in the key's transponder is the correct one for your vehicle. This is the reason why doing hot-wiring or altering the ignition system of the vehicle to start it. The chip in the car key confirms that the owner is the person who is the owner of the vehicle. This can help to reduce car theft. Regular transponder keys are designed like regular keys and have a plastic top. The chip is inside the plastic portion of these keys. There are several different cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe. When the transponder key is inserted into the ignition barrel, a circuit within 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 back to the car. If the computer in the car detects the signal as correct, it will disable vehicle immobilizer so that the engine can start. If the car doesn't recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and a siren. G28 is designed to discourage individuals from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and committed thief may still be able to get around this system employing a device designed to take over the signal. As you can see there are quite a number of benefits to having transponder keys. This is something that all vehicle owners should consider if they are looking to safeguard their investment and decrease the risk of theft. Key Fobs In addition to locking and unlocking doors, launching the car remotely, or making chirping sounds to help find a car in a parking lot, today's key fobs can also turn on a heated steering wheel or roll down all windows with a single button push. A lot of these additional features may appear 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. The frequencies are transmitted through a small antenna located within the middle of the key. The transmission is encrypted, which helps to stop others from stealing and re-transmitting the signal. You can program a keyfob in different ways based on the model and make of your vehicle. You can sometimes do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or an additional fob. When you press a key fob's button the microchip inside sends an informational code to the car's radio that it is linked to. The receiver compares this information to the signals that are allowed in the fob and then either opens or closes the door. If the information doesn't match the fob's information, the car won't be allowed to run. Once the car has been associated with a particular fob, it can only receive signals from the device. As a result, other fobs won't work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it. Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements sold by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems can be programmed by consumers without the need of an authorized dealer.
