Self Programming
The ignition keys have evolved as has the technology of cars. Gone are the days of simple mechanical keys that could be made at an hardware store for less than $10. The latest models come 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.
There are many types of car key programming that can be performed by professional locksmiths. Certain are complicated and require sophisticated tools. These tools are not accessible to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other types of programming for car keys are a lot simpler and can be performed by the average person. These are done using the onboard diagnostic port, which is accessible via a tool specifically designed for key-fob programming. A locksmith can perform this method with the assistance of an online guide as well as the owner's manual.
Professional locksmiths are able to program a replacement or new car key fob swiftly. This is the ideal option for vehicle owners as they can provide a complete range of services. They also can provide a competitive price and peace of mind that the new key will work properly.

Key Programmers
Modern vehicles require a key-programming procedure to initialize their vehicle's systems and start the car. In certain instances the key needs to be programmed by an auto locksmith or dealer. The key might not function properly or not start the car in any way. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. It is best to have two keys that work with your current car so you can program the replacement key when required.
A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to copy data 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 allows them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.
There are reprogram car key of keyprogrammers that are available, and they come in all shapes and sizes. Some are inexpensive while others are sophisticated and could cost thousands of dollars. Certain are designed for specific automobiles and offer advanced diagnostics of the vehicle's electronic system.
If you want to program the new key into your vehicle, refer to the owner's manual to find out how to do it. Certain manufacturers employ proprietary technology that guarantees that the dealership is the only entity that can create new keys. However, other manufacturers make it easy for anyone to do it themselves.

They are less expensive than visiting a dealer but they aren't cheap. Before buying one do some research on the seller. Some aren't trustworthy and may damage your vehicle.
Transponder Chips
If your car is made in the last 20 years, chances are it has a transponder inside of it. This is a little piece of plastic in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
The chip emits an low-level radio signal once it is activated by an electromagnetic field. This signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the transponder chip of the key is the correct one for your car.
This stops the vehicle from starting by hot-wiring, or by tampering. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip is inside the plastic portion of these keys. There are various cuts: a standard cut, a Laser cut (also known as a sidewinder or Ford Tibbe), and the Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is put into ignition barrel. The signal is absorbed by the chip, which then transmits a signal the vehicle. If the computer inside the car is able to recognize the signal as being correct it will turn off the vehicle immobilizer, allowing 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 will notify you via flashing lights and an alarm. This is designed to discourage people from attempting to hack into the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal can still get around this system by using a specific device that detects the signal.
As you can see, there are quite a few advantages to getting transponder keys. Every car owner should take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
In addition to locking and unlocking doors, starting the car from a distance or making chirping sounds to help find a car in a parking lot, today's key fobs can also switch on a heated steering wheel or roll down all windows with a single click. A lot of these additional features may seem convenient, but they can also make it difficult for you to keep the keys to your car.
Key fobs utilize radio frequencies to communicate with each other and with the car. These frequencies are sent by a small antenna in the middle of the key. This signal is encrypted to stop others from intercepting or replicating the signal.
There are a few different ways to program a key fob, based on the vehicle's make and model. Certain models allow you to do this 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 press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is linked to. The receiver compares the information with the 'allowed signals' stored in the key fob, and then it opens or closes the car's doors. If the information does not match the signals, the car will not be allowed to operate.
Once the car has been associated with a particular fob, it only accepts signals from the device. Other fobs will not work with the car, even though they appear like. This ensures the security of the computer system that runs the car and prevents unauthorised key fobs from taking control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge that can only be found in the dealer service department. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems can be programmed by the consumer without the need of a dealership.
