Key Programmers

The reason for this is that the new key has not been programmed to the car's system - and this can be very costly. It is best to have two keys that work for the modern automobile so that you can program the replacement key when required.
A keyprogrammer can reprogram the transponder chip on an entirely new mechanical key or key fob. It can also clone information from an existing key in order to create duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface for working with an immobilizer system.

Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. It's a tiny plastic piece in the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal is then taken up by the antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This stops the vehicle from being started by either hot-wiring or by altering the key. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys look like regular keys made of metal but have caps made of plastic. The chip itself is housed inside the plastic portion of the key and there are a few different types of cuts on the keys: a standard cut and program car key, a laser cut and program car keys (also called a sidewinder), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car is able to recognize the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the right one, it will prevent the engine from running and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from attempting to hack into the vehicle, however it isn't a foolproof security measure. A skilled and determined thief could still be able to bypass this system by using a special device to intercept the signal.
As you can see, there are quite a number of advantages to having transponder keys. This is something that all vehicle owners should think about if they are looking to safeguard their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car keys programmer from a distance or making noises to aid in finding 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 press. Many of these extra features may seem convenient, but they can also make it harder for you to keep track of your car keys.
Key fobs communicate with each other and the car using radio frequencies that are transmitted via a small antenna located in the center of the key. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob based on your vehicle's model and make. Some cars allow you to do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or additional one.
When you hit the button on a key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver compares this information to the signals that are allowed inside the fob, and either opens or locks the door. If the information does not match the signals, the car will not be allowed to operate.
Once the car has been associated with a particular fob, it can only receive signals from the device. This means that other fobs will not 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 of the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place with the knowledge to create a replacement fob is in the service department of the dealer. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for an authorized dealer.
