This involves the reprogramming of a blank chip on your replacement key to ensure that it matches the current settings of your vehicle. Certain manufacturers make this simple however others require a locksmith or dealer.
Self-Programming
The ignition keys have evolved as has the technology of cars. The days of simple mechanical keys that could be made at the hardware store for less than $10. The newer models have computers with improved anti-theft protection. In order to work correctly, these vehicles require that a transponder chip key be programmed to the vehicle by a certified locksmith or car dealer/mechanic.
There are several kinds of car key programming that can be done by locksmiths who are professionals. Certain types are more complex and require sophisticated tools. These tools are not generally accessible to the general public and are used only by professionals. This kind 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 accomplished by the average person. They can be done by using the onboard diagnosis port, which is accessible with a special tool for key fob programming. Locksmiths can carry out this method with the help of a guide online and the owner's manual.
Locksmiths with experience can program a brand new or replacement car key fob fast and precisely. This is the best choice for a vehicle owner since they can provide a complete range of services. They also provide an affordable cost and assurance that the replacement key will work correctly.

You can be assured that the new key will function and is programmable for your car. You will have to pay the dealer for programming and replacement keys if you don't.
Key Programmers
Modern cars require a key-programming process to start the vehicle's system and start the car. In a number of cases keys must be configured by the dealer or auto locksmith. This is because the key might not function correctly, or it will not start the vehicle at all. This is because the key hasn't yet been programmed into the car's system. This can be costly. This is why it's a great idea to always have two keys that work for a modern car and have the replacement key programmed when required.
A keyprogrammer can reprogram a transponder chip on the new mechanical key or key fob. see this is also able to clone data from an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional interface to work with an immobilizer system.
There are many different types of keyprogrammers that are available on the market. They come in all sizes, shapes, and colors. Some are inexpensive, while others are very advanced and could cost thousands of dollars. Certain models are specifically designed for certain types of cars, and they can even provide advanced diagnostics for your car's electronic systems.
Refer to the owner's manual of your vehicle to learn how to program keys for your vehicle. Certain manufacturers employ proprietary technology that makes sure that the dealership is the only entity able to create new keys, but other manufacturers make it simple for anyone to do it on their own.

They are cheaper than visiting a dealer however, they aren't cheap. Before buying one do some research on the seller. Some aren't trustworthy and could cause damage to your vehicle.
Transponder Chips
If your car was built in the last 20 years, then it has a transponder inside of it. This is a little piece of plastic on the back of your key that contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When it is activated by an electro-magnetic field the chip emits a low-frequency signal. The signal is taken up by an antenna attached to the ignition barrel. The computer system in the vehicle can then verify that the key's transponder chip is the correct one for your car.
This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the key also proves that you are the legitimate owner of the vehicle. This helps to reduce the risk of theft from your car.
Regular transponder keys are designed like regular keys and have an outer layer of plastic. The chip itself is housed within the plastic part of the key and there are a few different kinds of cuts available on these keys: a regular cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal is received by the chip which sends a signal to the vehicle. If the onboard car computer detects this signal as the correct one, it will shut down the vehicle's immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder signal as being the correct one, it will keep the engine from running and will notify you by flashing its lights and sounding an alarm. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief can still get around this system by using a specific device that detects the signal.
It is evident that a transponder is a great option. This is something that all vehicle owners should think about if they want to protect their investment and decrease the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start your vehicle remotely, make chirping noises to help locate cars, or turn on the heated steering wheel. A lot of these additional features may appear convenient however they could make it difficult for you to keep track of your car keys.
Key fobs communicate with one with the car via radio frequencies which are transmitted through an antenna in the center of the key. The signal is encrypted to block other key fobs from stealing or stealing the signal.
Keyfobs can be programmed in a variety of ways depending on the model and brand of your car. Some cars allow you to do it yourself. However, most newer models require you to visit a professional locksmith or dealer for them program a replacement key fob or additional one.
When you press the button on a key fob the microchip transmits a signal to the receiver in the car that it is paired. The receiver then compares the data with the 'allowed signals' stored in the key fob and then opens or locks the car's door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't 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 identical. This ensures the security of the computer system that runs the car and prevents unauthorized key fobs gaining control over it.
The majority of newer dealerships will only accept vehicles that have original fobs, or genuine replacements supplied 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 fobs from the aftermarket typically for older models with less sophisticated systems can be programmed by customers without the need of a dealership.
