These cars require a transponder-chip integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.

Professional locksmiths can perform various kinds of programming for keys to cars. Certain types are extremely complex and may require advanced tools. These tools are usually not available to the general public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.

Other types of car key programming are a lot simpler and can be performed by anyone who is able to.

It is best to have two keys that work for your modern car so you can program the replacement key whenever required.

A keyprogrammer is a device that recodes the transponder chip into a new key fob or mechanical key. It is also able to clone data of an existing key and allow duplicate keys to be created. 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 a computer. They also have a bidirectional user interface to work with an immobilizer system.

Transponder Chips

If your car was built in the past 20 years, chances are it contains a transponder chip within of it. It's a small plastic thing inside the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.

When it is activated by an electromagnetic field, the chip emits a low level signal. This signal is then received by a specific antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for your particular car.

This stops the vehicle from starting by hot-wiring, or by manipulating. The chip in 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 look like regular metal keys but they have a plastic cap. The chip is located inside the plastic part of these keys. There are several different cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.

The circuit in the induction coil will emit an electrical signal when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer, allowing the engine to start.

If the car does not recognize the transponder signal as being the proper one, it will prevent the engine from starting and will notify you by flashing its lights and sounding siren. This feature is designed to deter people from trying to alter the vehicle, but it is not a foolproof security measure. A skilled and skilled criminal could still bypass this system with a specially designed device that detects the signal.

As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should consider if they are looking to safeguard their investment and minimize the chance of theft.

Key Fobs

Key fobs today can do more than just lock and unlock doors. They can also start the car key programmer remotely, make chirping noises to help locate the car, or switch on the heated steering wheel. These additional features can make it difficult to locate your car keys.

Key fobs use radio frequencies to connect with one another and with the car. These frequencies are sent via a small antenna that is located inside the middle of the key. The transmission is encrypted, which helps keep others from stealing and retransmitting the signal.

There are several ways to program a key fob depending on the vehicle's model and make. It is possible to do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.

When you press a key fob's button the microchip inside sends an informational code to the car's receiver that it is paired with. The receiver compared the information with the 'allowed signals' stored in the key fob, and then opens or locks the car's door. If the data does not match, the car will not be allowed to operate.

When a car is connected with a specific fob it will only accept signals from that specific device. In turn, other fobs won't work with the vehicle, even though they have the same appearance. This safeguards the integrity of the computer system in the car and prevents unauthorized key fobs gaining control over it.

Most dealerships with newer cars will only accept cars with original fobs or genuine replacements sold by the manufacturer. This is because the process of creating a replacement fob requires technological and security expertise that can only be found in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems -- can be programmed by consumers without the need for a dealership.
