This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. This is why it's a good idea to always have two keys working for modern vehicles and to have the replacement key programmed when necessary. Keyprogrammers are devices that can recode the transponder chip in the form of a new mechanical or key fob key. It also can clone data from an existing key to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port.

Transponder Chips If your car was manufactured within the past 20 years, chances are it has a transponder chip inside of it. This is a little plastic thing in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle. When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal is then received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your car. This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key confirms that the owner is the person who is the owner of the vehicle. This helps to reduce the risk of theft from your car. Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is contained inside the plastic portion of the key, and there are a few different types of cuts on the keys: a standard cut, a laser cut (also called a sidewinder), or a Ford Tibbe key. When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer onboard the car detects the signal as correct it will turn off the car immobilizer to allow the engine start. If the car does not recognize the transponder signal as being the correct one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This system is designed to deter people from tampering with the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal could still be able to get around this system using a special device to intercept the signal. As you can see there are quite number of advantages to having transponder keys. This is something that all vehicle owners should think about if they want to safeguard their investment and reduce the chance of theft. automotive key programming near me In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find the car in a parking space, today's key fobs can also turn on a heated steering wheel or open all windows with just a single push. A lot of these features might seem useful however they could make it harder for you to keep the keys to your car. Key fobs are able to communicate with each with the car via radio frequencies that are transmitted through an antenna in the center of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal. You can program a keyfob in various ways based on the make and model of your car. Certain cars let you do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob or an additional one. When you press the button on a key fob the microchip sends signals to the receiver inside the vehicle with which it is linked. The receiver compares this information with the 'allowed' signals inside the fob, and either opens or locks the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to operate. Once the car is paired with a particular fob, it will only receive signals from that specific device. Other fobs will not work with the car, even though they look like. This ensures the security of the computer system that runs the vehicle and stops unauthorized key fobs gaining control over it. Most newer car dealerships will only work with cars with original fobs, or genuine replacements offered by the manufacturer. The reason for this is that the only place that has the experience to design 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 consumers without the need for an authorized dealer.
