Self-Programming
The ignition keys have developed along with the car technology. The days of the simple mechanical keys that you could make at a hardware shop for less than $10 are gone. The latest models come with computers with improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
Professional locksmiths are able to perform various types of programming for keys to cars. Some are extremely complicated and may require sophisticated tools. These tools aren't generally accessible to the general public and are utilized only by professionals. This type of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a lot of time.
Other types of car key programming are much simpler and can be performed by anyone who is able to. They are accomplished using the onboard diagnostic port, which is accessible with a special tool for key-fob programming. This procedure can be carried out by a professional locksmith using an online guide or the car's owner's manual.

Key Programmers
Modern cars often require a key programming procedure to start the system of the vehicle and allow the car to start. In certain instances the key needs to be programmed by an auto locksmith or dealer. This is because the key might not function properly, or it will not start the car at all. The reason for this is that the new key has not been programmed to the car's system. This can be quite expensive. This is why it's a good idea to have two keys working for a modern automobile, so you can get the replacement key programmed if required.
A keyprogrammer is a tool which can reprogram the transponder chip in an entirely new key fob or mechanical key. It can also clone the data of an existing key which allows duplicate keys to be created. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They come with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional interface that works with an immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They come in all shapes, sizes and colors. Some are cheap while others are sophisticated and could cost thousands of dollars. Certain models are specifically designed for automobiles and provide advanced diagnostics of the car's electronic system.
Check out the owner's manual to learn how to program a key for your vehicle. Certain manufacturers employ proprietary technology that ensures the dealership is the sole entity that can make new keys, however other manufacturers make it simple for anyone to do it on their own.

They are cheaper than going to a dealership but they aren't inexpensive. Make sure you look up the seller before buying one - some are not reliable and could damage your car.
Transponder Chips
If your car is made within the past 20 years, chances are it has a transponder chip inside of it. This is the little plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal is then amplified by the specific antenna that is attached to the ignition barrel of your vehicle. programming car key of the vehicle will then confirm that the transponder chip of the key is the right one for your car.
This prevents the vehicle from being started through hot-wiring, or by tampering. The chip in the car key verifies that the owner is the one who is the owner of the vehicle. This helps to reduce the risk of theft from your car.
Transponder keys look like regular keys made of metal, but with caps made of plastic. The chip is contained within the plastic portion of these keys. There are a variety of cuts such as a standard cut laser cut (also called a sidewinder or Ford Tibbe), and a Ford Tibbe.
A circuit within the induction coil will emit a signal when the transponder is inserted into ignition barrel. The signal will then get received by the chip, causing it to transmit a signal to the car. If the car's computer recognizes this signal as the right one, it will shut down the vehicle immobilizer and allow the engine to start.
If the car isn't able to recognize the transponder as the correct signal, it won't start the engine and notify you via flashing lights and an alarm. This is designed to discourage people from trying to alter the vehicle, however it's not a 100% security measure. A skilled and determined thief could still bypass this system with a specially designed device that intercepts the signal.
As you can see there are quite a few advantages to getting transponder keys. Every car owner should consider this in order to safeguard their investment and reduce the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely, or making sound chirps to help locate a car in a parking lot, today's key fobs can also turn on the heated steering wheel or roll down all windows with just a single press. These additional features could make it difficult to find your car keys.
Key fobs communicate with one other and with the car through radio frequencies that are transmitted through an antenna in the middle of the key. This communication is encrypted, which helps stop others from stealing and retransmitting the signal.
There are many ways to program a key fob based on the make and model. Certain models allow you to do this by yourself. However, most newer models require you to visit an expert locksmith or dealer in order for them program a replacement key fob, or an alternative one.
When you press a key fob's button the microchip inside sends an encoded code to the car's radio that it is paired with. The receiver compares the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's door. If the data doesn't match, a chirping sound is heard and the car isn't permitted to operate.
Once the car is paired with a particular fob, it will only receive signals from that specific device. Other fobs will not work with the car, even if they look like. This protects the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only deal with cars that have original fobs or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. Certain aftermarket fobs, typically those for older models with less advanced systems, can be programmed without the need for a dealership.
