Key Programmers Modern cars require a key-programming procedure to set up their systems and to start the car. In a number of cases the key needs to be programmed by the auto locksmith or dealer. The key may not function properly or not start the car at all. This is because the new key hasn't been programmed to the automobile's system – and this can be very costly. This is why it's a good idea to always have two keys working for a modern car and have the replacement key programmed when needed. Keyprogrammers are devices that can recode the transponder chip into an entirely new mechanical or key fob key. It is also able to copy the data from an existing key which allows duplicate keys to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped 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 that are available and they are available in all shapes and sizes. Some are inexpensive, while others may cost thousands of dollars.

Transponder Chips Transponder chips are likely be found in cars manufactured within the past 20 years. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for the vehicle you own. The chip emits a low-level radio signal when it is activated by an electromagnetic field. The signal is then absorbed by a special antenna 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 prevents the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key confirms that the owner is the one who owns the vehicle. This helps to prevent car theft. Transponder keys look like regular metal keys but have a plastic cap. The chip is inside the plastic part of the keys. There are a variety of cuts: a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and a Ford Tibbe. A circuit within the induction coil emits a signal when the transponder is put into an ignition barrel. The signal will then get received by the chip and cause it to transmit a signal back to the car. If the computer inside the car is able to recognize the signal as being correct, it will disable vehicle immobilizer to allow the engine start. If the vehicle doesn't recognize the transponder as being the proper signal, it will not start the engine, and will warn you with flashing lights and siren. This is designed to discourage people from trying to tamper with the vehicle, but it is not a foolproof security measure. A determined and skilled thief could still evade this system with a specially designed device that blocks the signal. It is evident that a transponder is a great option. This is something that all vehicle owners should consider if want to protect their investment and reduce 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 a car in a parking lot Key fobs today can also activate the heated steering wheel or roll down all of the windows with a single button push. A lot of these features may appear convenient however they could make it difficult for you to keep track of your car keys. Key fobs communicate with each with the car via radio frequencies which are transmitted through an antenna in the center of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal. There are a few different ways to program a key fob depending on the vehicle's model and make. It is possible to do this yourself, but the majority of newer vehicles require an expert locksmith or dealer to program a replacement or an additional fob. When you press the button on a key fob the microchip transmits an indication to the receiver inside the vehicle with which it is paired. The receiver compares this information with the signals that are allowed on the fob and either opens or locks the door. If the information doesn't match, a chirping sound is heard and the car isn't permitted to function. Once the car is connected to a specific fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle even though they have the same appearance. This safeguards the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control over it. The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer's service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems can be programmed by the consumer without the need of an authorized dealer.
