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

Professional locksmiths can perform a variety of different types of programming for car keys. Some are extremely complicated and require sophisticated tools. These tools aren't generally accessible to the general public and are used only by professionals. This type of programming for car keys is known as EEPROM Programming and requires soldering, electronic expertise and a significant amount of time.

This is why it's a good idea to have two keys that work for a modern automobile, so you can get the replacement key programmed when required.

A keyprogrammer is a tool that can recode the transponder chip on a new mechanical or key fob key. It can also clone information from an existing key in order to create duplicates. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with the computer, and they also have a bidirectional interface for working with the immobilizer system.

Transponder Chips

If your car is made within the past 20 years, chances are it contains a transponder key programmer chip within of it. It's the small plastic piece inside the head of your car key that houses an RFID (Radio Frequency ID) chip with a code unique to your car.

When it is activated by an electromagnetic field the chip emits a low-level signal. This signal is then absorbed by a special antenna that is attached to the barrel of ignition. The computer system of the vehicle is then able to verify that the transponder chip of the key is the right one for your vehicle.

This is what prevents from modifying or hot-wiring the ignition system of your vehicle to get it started. The chip inside the key verifies that the owner is the person who is the owner of the vehicle. This will help reduce car theft.

Transponder keys resemble normal keys but they have caps made of plastic. The chip is contained within the plastic part of the key, and there are a few different cuts that can be found on these keys: a standard cut laser cut (also called a sidewinder key), or a Ford Tibbe key.

A circuit inside the induction coil emits a signal when the transponder is placed in the an ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the onboard car computer recognizes this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to start.

If the car does not recognize the transponder signal as the right one, it will stop the engine from running and will alert you by flashing its lights and sounding an alarm. This is designed to discourage people from attempting to tamper with the vehicle, but it is not a foolproof security measure. A skilled and committed thief may still be able to escape this security system by using a special device to take over the signal.

It is evident that a transponder is a great option. Every car owner should consider this if they wish to protect their investment and minimize theft risk.

Key Fobs

Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, emit chirping sounds to help locate cars, or switch on the heated steering wheel. These extra features can make it difficult to locate your car keys.

Key fobs make use of radio frequencies to communicate with each other and with the car. These frequencies are transmitted by a small antenna inside the middle of the key. This communication is encrypted to prevent others from stealing or stealing the signal.

There are several ways to program a key fob depending on the vehicle's make and model. It is possible to do this yourself, but most newer vehicles require an expert locksmith or dealer to program a replacement or a second fob.

When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle with which it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob and then opens or locks the car door. If the information doesn't match, the car will not be allowed to run.

After the car has been connected to a specific fob, it can only receive signals from the device. Other fobs will not work with the car, even though they look identical. This safeguards the integrity of the computer system in the car and blocks the use of unauthorized key fobs to gain control over it.

Most newer car dealerships will only work 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 knowledge 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 customers without the need for dealers.
