It is also able to copy the data of an existing key, allowing duplicates to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that enables them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
Transponder chips are likely to be found in vehicles manufactured in the last 20 years. It's the tiny plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is attached to the ignition barrel of your vehicle. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the right one for your car.
This prevents the vehicle from being started by hot-wiring or manipulating. The chip in the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is contained within the plastic portion of these keys. There are several different cuts: a standard cut, Laser cut (also known as 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 will be taken up by the chip and cause it to transmit a signal back to the car. If the car's computer recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as the correct signal, it won't start the engine and will warn you with flashing lights and siren. This is designed to discourage people from attempting to alter the vehicle, but it isn't a foolproof security measure. A skilled and determined criminal could still be able to get around this system using a device that can intercept the signal.
As you can see there are quite a number of advantages to having a transponder key. This is something that all car owners should consider if they want to protect their investment and decrease the chance of theft.

A lot of these features may seem convenient however they could make it more difficult to keep the keys to your car.
Key fobs make use of radio frequencies to connect with one another and the car. These frequencies are sent through a small antenna located within the middle of the key. The transmission is encrypted, which helps to keep others from stealing and replicating the signal.
There are a few different ways to program a key fob, based on the model and make. Some cars allow you to do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press a key fob's button it transmits an encoded code to the car's receiver that it is linked to. The receiver compared the information with the permitted signals stored on the key fob and then locks or opens the car's door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car is linked with a specific fob it will only receive signals from the device that is associated with it. In turn, other fobs won't be able to work with the vehicle even though they look the same. This helps to protect the integrity of the car's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. This is because the only place that has the expertise to prepare a replacement fob is in the service department of a dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems can be programmed by customers without the need of an authorized dealer.
