The latest models are equipped with computer systems that are more secure against theft. 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 car keys. Some are extremely complicated and may require advanced tools. These tools are generally not available to the general public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.

Key Programmers
Modern vehicles require a key-programming procedure to initialize their vehicle's 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 work correctly or will not start the car in any way. The reason for this is that the new key hasn't been programmed to the automobile's system - and this can be quite expensive. It's best to have two keys that work for your modern car so you can program the replacement key whenever needed.
A keyprogrammer can recode a transponder chip on the new mechanical key or key fob. It can also clone the data of 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 come with diagnostic software that allows them to communicate with computers as well as an interface that works bidirectionally with the immobilizer system.
There are many various kinds of keyprogrammers that are available and they are available in a variety of shapes and sizes. Some are inexpensive while others could cost thousands of dollars.

These are cheaper than visiting a dealership, but they're still expensive. Be sure to research the seller before purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, it is likely that it has a transponder inside of it. This is the little plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
When it is activated by an electromagnetic field the chip emits a low-frequency signal. This signal then gets absorbed by the special antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the transponder chip of the key is the correct one for your car.
This prevents the vehicle from starting by hot-wiring or manipulating. The chip in the car key verifies that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip is inside the plastic part of these keys. There are several different cuts: a standard cut, Laser cut (also known as a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit inside the induction coil emits signals when the transponder is inserted into the ignition barrel. The signal will be absorbed by the chip, causing it to transmit a signal back to the car. If the car's computer detects this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and siren. This feature is designed to discourage people from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief may still be able to escape this security system by using a device that can detect the signal.
As you can see there are quite few advantages to getting a transponder key. This is something that all vehicle owners should think about 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 chirping sounds to help find a car in a parking space Key fobs today can also activate the heated steering wheel or roll down all of the windows with a single button press. These additional features can make it difficult for you to locate your car keys.
Key fobs utilize radio frequencies to communicate with each other and the car. These frequencies are transmitted through a small antenna located within the middle of the key. This signal is encrypted to prevent others from stealing or stealing the signal.
You can program a keyfob in various ways based on the model and brand of your vehicle. Certain cars let you do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a new key fob, or an alternative one.
When you hit the button on a key fob, the microchip inside transmits an encoded code to the car's receiver it is linked to. The receiver then compares this information with the signals that are allowed in the fob and then either opens or locks the door. If the information isn't in line an chirping sound is heard and the car isn't able to operate.
Once the car is connected to a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle even if they appear similar. This protects the integrity of the computer system in the vehicle and stops the use of unauthorized key fobs to gain control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are sold by the manufacturer. The reason for this is that the only place that has the knowledge to create an appropriate replacement fob is a dealer's service department. Some aftermarket fobs, usually those from older models with less advanced systems, can be programmed without the need for a dealer.
