It's best to have two keys that are compatible for the modern automobile so that you can program the replacement key whenever required.
A keyprogrammer can reprogram a transponder chip on a new mechanical key or key fob. It can also clone the data of an existing key which allows duplicate keys to be created. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that enables them to communicate with computers as well as a bidirectional interface for working with the immobilizer system.
There are a number of different types of keyprogrammers available that are available, and they come in a variety of sizes and shapes.

Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. It's a small plastic piece on the back of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to the specific vehicle you own.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is taken up by an antenna attached to the barrel of ignition. The computer system of the vehicle can then verify that the transponder chip of the key is the right one for your car.
This stops the vehicle from starting by either hot-wiring or by manipulating. The chip inside the car key verifies that the owner is the person who owns the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are a few different cuts that can be found on the keys: a standard cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
A circuit within the induction coil emits signals when the transponder is placed in the ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer on the car detects this signal as the right one, it will disable the vehicle immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and will notify you via flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However, it is not an unbreakable security measure. A determined and skilled thief could still evade this system using a special device that blocks 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 think about if they are looking to safeguard their investment and decrease the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making sound chirps to help locate the car in a parking space keys of today can also activate a heated steering wheel or roll down all of the windows with just a single press. Many of these extra features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through a small antenna located in the middle of the key. The communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.
You can program a keyfob in various ways based on the model and make of your vehicle. You may be able to do it yourself, but the majority of newer cars require that you visit a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on your key fob the microchip inside sends a code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then locks or opens the car door. If the information does not match, the car will not be allowed to drive.
When a car is connected with a specific fob, it will only receive signals from the device that is associated with it. Other fobs won't work with the car, even if they appear similar. This protects the integrity of the computer system of the car and blocks unauthorised key fobs from taking control of it.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place that has the knowledge to create a replacement fob is in the service department of the dealer. Certain aftermarket fobs, typically ones for older models that have less sophisticated systems can be programmed without the need for a dealer.
