Key Fobs
Key fobs allow you to consolidate several functions into one portable package. They make it possible for vehicle owners to control the door locks, ignition systems and more with the press of a button or a proximity scan. This eliminates the need for physical keys that are traditional and can reduce costs related to replacing lost or stolen keys for cars. Fobs can also be used to provide controlled entry in commercial and industrial buildings. By connecting their backend software to a central server facility administrators can program individual RFID readers and assign levels of access for employees, customers, or guests.
Despite the fact that a majority of vehicles are designed to be secure, there are some who are willing to exploit security weaknesses. Utilizing inexpensive hardware, it's possible for a few criminals to attack a vehicle's security and steal the car. Fobs have security features built-in to guard against these attacks. Specifically, they transmit passcodes that change every time the fob is activated, and then automatically expire after a specified time.
Fobs are also designed to be secure from wireless hacking. Modern key fobs are equipped with advanced encryption protocols that block hackers from intercepting codes. They also use RFID readers with an unique ID that prevents multiple fobs from having access to the same area at the same time.
Before you attempt to re-program your key fobs, consult your owner's manual to find specific instructions specific to your vehicle. The general reprogramming process is the same across most major models, but they there will be minor differences in the details. In some cases the locksmith might be required to assist you.
The first step in the reprogramming process is to take out your old fob and place it in a secure location. It is essential to have all your other fobs ready to go.

Transponder Chips
Transponder chips are found in the top part of modern smart keys, fobs and remotes. They allow your car to start whenever you make use of them. The chip transmits an identification code to the engine immobilizer in your car, letting it know that it's a valid key and not a potentially stolen one. The chip transmits the ID code by radio signal to the car's computer. If the ID code matches that in the vehicle's memories the security system will turn off immobilizers and allow the engine to start when the ID code is found to match. Once this happens the security light will go off on the dashboard.
If you've got a new car with a transponder but isn't recognizing your new key, you can contact an expert locksmith to cut and program a replacement for you. Make sure that the replacement key is an uncut one and that you buy it from an authorized locksmith. Secondhand keys cannot be recut, and those that have been

car key programmed. This is why it is so important to have a spare key you can use to stop theft of your vehicle.
