It is recommended to have two keys that are compatible for the modern automobile so that you can program the replacement key whenever needed.
A keyprogrammer is a tool that can recode the transponder chip in a new key fob or mechanical key. It is also able to clone data from an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that allows them to communicate with the computer, and they also have an interface that works bidirectionally with the immobilizer system.

Transponder Chips
Transponder chips are likely be found in vehicles manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.
The chip emits a low-level radio signal when it is activated by an electromagnetic field. This signal then gets absorbed by the special 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 chip in the key's transponder is the correct one for your vehicle.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip in the key also proves that you are the legal owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys, but with an outer layer of plastic. The chip is located inside the plastic part of the keys. There are various cuts such as a standard cut a Laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the car's computer recognizes this signal as being the correct one, it will disable the vehicle's immobilizer and allow the engine to 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. This feature is designed to discourage people from trying to alter the vehicle, however it is not a foolproof security measure. A skilled and skilled criminal could still evade this system by using a specific device that intercepts the signal.
You can see that a transponder is a great option. This is something that all vehicle owners should consider if want to protect their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making chirping sounds to help find a car in a parking space keys of today can also activate a heated steering wheel, or open all windows with a single button click. These extra features can make it difficult for you to locate your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted by an antenna that is located in the center of the key. This signal is encrypted to stop others from stealing or stealing the signal.
Keyfobs can be programmed in various ways based on the model and brand of your vehicle. Some cars allow you to do it yourself. However, most newer 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 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 with the 'allowed' signals inside the fob, and either opens or locks the door. If the data doesn't match the signals, a chirping sound can be heard and the car isn't able to operate.
After the car has been paired with a specific fob, it will only accept signals from the device. Other fobs won't work with the car, even if they look like. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security skills that is only available in the dealer's service department. Some aftermarket fobs, usually those for older models that have less advanced systems, can be programmed without the need for a dealership.
