Modern models come with computers that are enhanced security against theft. These cars require a transponder-chip integrated key to be programmed by a professional locksmith, car dealer or mechanic in order to function properly.
Professional locksmiths can perform various kinds of programming for car keys. Some are very complex and may require sophisticated tools. These tools are usually not available to the general public and are only used by professionals. This kind of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a significant amount of time.

Transponder Chips
Transponder chips are likely be found in cars that were manufactured within the last 20 years. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When activated by an electro-magnetic field the chip emits a low-frequency signal. This signal is then absorbed by the special antenna that is positioned around the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your car.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip inside the key also verifies that you are the legal owner of the vehicle. This can help to reduce car theft.
Regular transponder keys are designed like regular keys and have a plastic top. The chip itself is housed inside the plastic portion of the key, and there are different cuts that can be found on these keys: a cut laser cut (also called a sidewinder key), or a Ford Tibbe key.
A circuit inside the induction coil emits signals when the transponder is put into the ignition barrel. The signal is absorbed by the chip, which then transmits a signal to the vehicle. If the computer in the car recognizes the signal as correct, it will disable vehicle immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as the correct one, it will keep the engine from starting and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage those who would attempt to alter the vehicle. However it isn't an unbreakable security measure. A skilled and committed thief may still be able to get around this system using a device that can intercept the signal.
You can see that a transponder is a great option. This is something that all car owners should consider if are looking to safeguard their investment and minimize the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making noises to aid in finding the car in a parking space, today's key fobs can also activate a heated steering wheel or roll down all of the windows with just a single click. Many of these extra features may seem convenient but they could make it harder for you to keep the track of your car keys.
Key fobs use radio frequencies to communicate with each other and the car. The frequencies are transmitted by a small antenna within the middle of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
There are several ways to program a key fob based on the model and make. Some cars allow you to do it yourself. However, the majority of newer models require you to visit a professional locksmith or dealer for them program a replacement key fob, or an alternative one.
When you press a key fob's button it transmits a code to the car's radio that it is paired with. The receiver compared this information to the signals that are allowed in the fob and then either locks or opens the door. If the information does not match the fob's information, the car won't be allowed to run.
Once the car has been associated with a particular fob, it can only receive signals from that device. As a result, other fobs will not work with the vehicle even if they look the same. This safeguards the integrity of the computer system that runs the vehicle and stops unauthorised key fobs from taking control of it.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
