The newer models have computers that have improved anti-theft security. In order to work correctly, these vehicles require that a transponder chip key be programmed into the vehicle by a professional locksmith or mechanic/car dealer.

These tools are not generally accessible to the general public and are used only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.

This way, you can ensure that the new key is programmed to your vehicle and will function. You'll need to pay the dealer for programming and replacement keys if they don't.

Key Programmers

Modern automobiles typically require a key programming process to start the system of the vehicle and allow the vehicle to start.

This is because the key hasn't yet been programmed into the car's system. This can be costly. It is best to have two keys that are compatible for your modern car so you can program the replacement key whenever needed.

A keyprogrammer is a device that recodes the transponder chip into an entirely new mechanical or key fob key. It can also clone the data from an existing key which allows duplicate keys to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software that allows them to communicate with computers. They also have a bidirectional user interface that works with an immobilizer system.

There are many different types of keyprogrammers available that are available and they are available in all shapes and sizes.

They are less expensive than visiting a dealership however, they aren't inexpensive. Be sure to research the seller before purchasing one - some are not reliable and can damage your car.

Transponder Chips

If your car was built within the past 20 years, chances are it contains a transponder chip within of it. It's a tiny piece of plastic on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.

When it is activated by an electromagnetic field the chip emits a low-level signal. The signal is then taken up by the antenna that is positioned around the ignition barrel of your car. This allows the car's computer system to determine if the transponder chip inside the key is the correct one for your specific vehicle.

This prevents the vehicle from being started through hot-wiring or tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This can help to reduce car theft.

Regular transponder keys are shaped like regular keys and have a plastic top. The chip is housed within the plastic part of the key and there are a few different types of cuts on the keys: a cut, a laser cut (also called a sidewinder) or Ford Tibbe key.

When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out an electrical 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 immobilizer and allow the engine to start.

If the car does not recognize the transponder signal as being the right one, it will keep the engine from starting and will alert you by flashing its lights and sounding an alarm. This system is designed to deter those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined criminal may still be able to get around this system employing a device designed to take over the signal.

As you can see there are quite number of benefits to having transponder keys. All car owners should consider this when they want to safeguard their investment and decrease the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car from a distance or making sound chirps to help locate a car in a parking lot, today's key fobs can also activate a heated steering wheel, or roll down all of the windows with a single press. A lot of these additional features may appear convenient, but they can also make it more difficult to keep the keys to your car.

Key fobs communicate with each other and the car using radio frequencies that are transmitted through an antenna in the center of the key. The signal is encrypted to prevent others from stealing or modifying the signal.

There are many ways to program a key fob depending on your vehicle's model and make. Certain cars let you do this yourself. However, the majority of newer models require you to visit an expert locksmith or dealer in order to program a replacement key fob or an additional one.

When you hit the button on a key fob, the microchip inside transmits an informational code to the car's receiver it is paired with. The receiver then compares the data with the permitted signals stored on the key fob and then it opens or closes the car door. If the information doesn't match an chirping sound is heard and the car isn't permitted to operate.

After the car has been paired with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they appear similar. This ensures the security of the computer system that runs the vehicle and stops the use of unauthorized key fobs to gain control of it.

The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements supplied 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. However, some aftermarket fobs that are typically designed for older models with less sophisticated systems -- can be programmed by the consumer without the need of an authorized dealer.
