To function properly, these cars require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.

Professional locksmiths are able to perform various types of programming for keys for cars. Some are very complex and may require sophisticated tools. These tools are not accessible to the general public and are used only by professionals. This kind of car key programming is known as EEPROM Programming and requires soldering, electronic expertise, and a lot of time.

Key Programmers

Modern cars require a key-programming process to set up their systems and then start the vehicle. In some instances, the key will need to be programmed by an auto locksmith or a dealer. The key may not function properly or it may not even start the car at all. This is because the key has not yet been programmed into the vehicle's system. This could be costly. It is best to have two keys that work for your modern car so you can program the replacement key if needed.

Keyprogrammers are devices that can recode the transponder chip into an entirely new mechanical or key fob key. It is also able to copy information from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with computers. They also feature a bidirectional user interface to work with an immobilizer system.

Transponder Chips

If your car is made in the last 20 years, then it has a transponder chip inside of it. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a unique code for your vehicle.

The chip sends out a low-level radio signal when it is activated by an electromagnetic field. The signal is then taken up by the antenna that is fitted around 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 vehicle.

This stops the vehicle from starting by hot-wiring or manipulating. The chip inside the car key confirms that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is inside the plastic part of the keys. There are a variety of cuts that are a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe.

A circuit within the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is received by the chip which sends a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will disable the vehicle's immobilizer and allow the engine to start.

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 an alarm. This feature is designed to deter people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief can still get around this system with a specially designed device that detects the signal.

As you can see there are quite few advantages to getting a transponder key. This is something that all vehicle owners should consider if they want to protect their investment and reduce the chance of theft.

Key Fobs

In addition to locking and unlocking doors, launching the car remotely or making sound chirps to help locate the car in a parking space, today's key fobs can also activate a heated steering wheel or open all windows with just a single push. These extra features can make it difficult for you to locate your car keys.

Key fobs are able to communicate with each with the car via radio frequencies that are transmitted via an antenna that is located in the center of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.

Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. It is possible to do this yourself, but most newer cars require that you visit a locksmith shop or a professional to program a replacement or an additional fob.

When you press the button on your key fob, the microchip inside transmits an informational code to the car's receiver it is linked to. The receiver then compares the data with the 'allowed signals' that are stored on the key fob and then locks or opens the car's door. If the data does not match the signals, the car will not be allowed to drive.

Once the car key reprogram is linked with a particular fob, it will only accept signals from that device. As a result, other fobs will not work with the vehicle, even though they appear similar. This safeguards the integrity of the computer system that runs the car and blocks unauthorized key fobs gaining control of it.

The majority of newer dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security skills which can only be obtained in the dealer service department. However, some fobs from the aftermarket typically for older models that have less sophisticated systems -- can be programmed by the consumer without the need of dealers.
