The latest models are equipped with computers with improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, car dealer or mechanic to function properly.
There are several kinds of car key programming that can be accomplished by locksmiths who are professionals. Some are complex and require sophisticated tools. These tools aren't usually accessible 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 time.
Other kinds of programming for car keys are much simpler and can be performed by anyone who is able to. They are typically done using the onboard diagnostics port, which can be accessed with the key-fob-programming device. This method can be performed by a trained locksmith using an online guide or the vehicle's owner's manual.

Key Programmers
Modern vehicles typically require a key programming procedure to start the system of the vehicle and allow the car to begin. In some cases, the key will need to be programmed by an auto locksmith or dealer. This is because the key may not function properly or start the car in any way. This is because the key has not yet been programmed into the car's system. This can be costly. This is why it's a good idea to have two working keys for a modern car, so you can get the replacement key programmed if needed.
Keyprogrammers are devices that can recode the transponder chip on an entirely new key fob or mechanical key. It is also able to copy the data from an existing key, allowing duplicates to be created. 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 a computer. They also have a bidirectional interface to work with an immobilizer system.

Transponder Chips
If your car is made within the last 20 years, it is likely that it has a transponder inside of it. This is a little plastic thing in the head of your key that houses an RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. The signal is then taken up by the antenna that is positioned around the ignition barrel of your car. The computer system in the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This is the reason why doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip inside the car key confirms that the owner is the person who owns the vehicle. This can help to reduce car theft.
Transponder keys look like regular metal keys but they have a plastic cap. The chip is contained within the plastic part of these keys. There are car key programer that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and Ford Tibbe.
The circuit in the induction coil will emit a signal when the transponder is put into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer recognizes this signal as being the correct one, it will disable the immobilizer on the vehicle and allow the engine to start.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and will notify you via flashing lights and an alarm. This function is designed to discourage those who would attempt to alter the vehicle. However, it is not an absolute security measure. A skilled and determined criminal could still be able to get around this system employing a device designed to take over the signal.
It is evident that a transponder is a great option. This is something that all vehicle owners should think about if they are looking to safeguard their investment and reduce the chance of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making noises to aid in finding a car in a parking lot keys of today can also turn on the heated steering wheel or roll down all windows with just a single click. These additional features can make it difficult to locate your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. The frequencies are transmitted via a small antenna that is located within the middle of the key. The transmission is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
You can program a keyfob in different ways based on the make and model of your car. It is possible to do this yourself, however most modern automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you hit the button on a key fob it transmits a code to the car's receiver that it is paired with. The receiver then compares this information to the signals that are allowed in the fob and then either locks or opens the door. If the information doesn't match the signals, the car will not be allowed to run.
Once the car is paired with a specific fob it will only accept signals from that device. Other fobs will not work with the car, even if they appear like. This protects the integrity of the computer system of the car and blocks unauthorized key fobs gaining control over it.
Most newer car dealers will only work on cars with original fobs or genuine replacements sold by the manufacturer. This is because the only place that has the expertise to prepare a replacement fob is in a dealer's service department. Certain aftermarket fobs, typically those from older models that have less advanced systems can be programmed with out the need for a dealership.
