The 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 are able to perform various kinds of programming for keys for cars. Certain types are more complex and require advanced tools. These tools are generally not available to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.

Other types of programming car keys are much simpler and can be done by the average person. These are done using the onboard diagnostic port, which can be accessed via a tool specifically designed for key-fob programming.

Modern cars require a key-programming method to set up their systems and to start the car. In some cases the key needs to be programmed by an auto locksmith or dealer. The key may not function properly or not start the vehicle at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be costly. This is why it's a great idea to have two keys working for a modern automobile and have the replacement key programmed if needed.

A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It is also able to clone information from an existing key which allows duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional interface for working with an immobilizer system.

There are a variety of keyprogrammers on the market. They come in all sizes, shapes and colors. Some keyprogrammers are cheap, while others may cost thousands of dollars.

Transponder Chips

If your car was manufactured in the last 20 years, then it contains a transponder chip within of it. It's the small plastic piece inside the head of the car keys cutting and programming key that has an RFID (Radio Frequency ID) chip with a code unique to your car.

When it is activated by an electro-magnetic field, the chip emits a low-level signal. The signal is then taken up by an antenna that is attached to the barrel of ignition. This allows the car's computer system to verify that the transponder chip that is in the key is the correct one for the car you have.

This prevents the vehicle from being started through hot-wiring, or by manipulating. The chip in the key also verifies that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.

Regular transponder keys are designed like regular keys and have a plastic top. The chip is located inside the plastic portion of the keys. There are various cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out a signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer inside the car recognizes the signal as correct it will turn off the car immobilizer so that the engine can start.

If the vehicle doesn't recognize the transponder signal as being the proper one, it will prevent the engine from running and will alert you by flashing its lights and sounding siren. This is designed to discourage people from trying to hack into the vehicle, but it isn't a foolproof security measure. A determined and skilled thief could still bypass this system using a special device that intercepts the signal.

As you can see there are quite number of advantages to having transponder keys. This is something that all car owners should consider if they want to safeguard their investment and minimize the risk of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also turn on the car from a distance, make chirping sounds to help locate cars or switch on the heated steering wheel. These extra features could make it difficult to locate your car keys.

Key fobs communicate with each other and with the car through radio frequencies which are transmitted via an antenna that is located in the middle of the key. The communication is encrypted, which helps prevent others from intercepting and replicating the signal.

There are a few different ways to program a key fob depending on the make and model. You may be able to do it yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.

When you press the button on a key fob the microchip transmits a signal to the receiver inside the vehicle that it is paired. The receiver then compares the data with the 'allowed signals' that are stored in the key fob, and then opens or locks the car door. If the data does not match the signals, the car will not be allowed to drive.

Once the car key cut and program is linked with a particular fob, it will only receive signals from that specific device. Other fobs won't work with the car, despite the fact that they appear similar. This is to safeguard the integrity of the vehicle's computer system and to prevent the use of unauthorized key fobs to gain control over the vehicle.

Most newer car dealerships will only deal with cars that have original fobs, or genuine replacements sold by the manufacturer. This is because the process of creating an appropriate replacement fob requires technical and security skills that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by consumers without the need of dealers.
