Self Programming
As car technology has evolved over the years, the ignition keys have also evolved as well. The days of the simple mechanical keys you could make at a hardware shop for less than $10 have gone. 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 in order to function properly.
There are a few different kinds of car key programming that can be accomplished by locksmiths who are professionals. Some are very complex and require sophisticated tools. These tools aren't usually available to the public and are utilized only by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic knowledge and a lot of time.
Other kinds of car key programming are much easier and can be done by anyone who is able to. They are typically accomplished by using the onboard diagnostics port which can be accessed with a special key-fob-programming tool. This procedure can be carried out by a locksmith who is trained with the help of an online guide or the vehicle's owner's manual.
Most professional locksmiths can program a brand new or replacement car key fob quickly and accurately. This is the best choice for owners of vehicles as they can offer a full range of services. They can also offer a competitive price and peace of mind that the replacement key will work correctly.

You will have to pay the dealer for programming and replacement keys if you do not.
Key Programmers
Modern vehicles require a key-programming procedure to start the vehicle's system and to start the car. In some cases the key will have to be programmed by an auto locksmith or dealer. The key might not function properly or not start the vehicle in any way. This is because the key has not yet been programmed into the vehicle's system. This could be costly. This is why it's a great idea to have two working keys for modern vehicles and to have the replacement key programmed if needed.
A keyprogrammer is a tool that recodes the transponder chip on a new mechanical or key fob key. It can also clone the data from an existing key and allow duplicate keys to be created. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software that allows them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.
There are many various kinds of keyprogrammers that are available, and they come in all sizes and shapes. Some are cheap while others are sophisticated and can cost thousands of dollars. Certain are designed for specific vehicles and can provide advanced diagnostics of the car's electronic system.
If you're interested in programming a new key to your vehicle, refer to the owner's manual for instructions on how. Certain manufacturers employ proprietary technology that guarantees that the dealership is the sole entity able to create new keys, however other manufacturers make it fairly easy for anyone to accomplish it on their own.
If you're not able to program a new key on your own, you can ask the dealership to do it for you, however it will cost a lot. You can also buy a keyprogrammer from the internet. These are cheaper than going to a dealer however they're not cheap. Before you purchase one make sure you research the seller. Some aren't trustworthy and could damage your vehicle.
Transponder Chips
Transponder chips can be found in cars manufactured in the last 20 years. This is a little plastic thing on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
When it is activated by an electro-magnetic field, the chip emits a low level signal. This signal is then taken up by the antenna that is fitted around the barrel that controls your ignition in your car. The computer system in the vehicle will then confirm that the key's transponder chip is the correct one for your vehicle.
This stops the vehicle from being started by either hot-wiring or by manipulating. The chip inside the car key confirms 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 appear like regular metal keys but have caps made of plastic. The chip itself is housed inside the plastic portion of the key, and there are a few different types of cuts on these programing keys: a cut laser cut (also called a sidewinder) or Ford Tibbe key.
A circuit within the induction coil will emit an electrical signal when the transponder is put into an ignition barrel. The signal will be absorbed by the chip and cause it to transmit a signal to the car. If the computer onboard the car is able to recognize the signal as valid it will turn off the car immobilizer to allow the engine start.
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 siren. This feature is intended to discourage people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and determined criminal might be able get around this system using a device that can intercept the signal.
As you can see there are quite few advantages to getting transponder keys. All reprogramme car key owners must take this into consideration in order to safeguard their investment and reduce theft risk.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the car remotely, emit chirping sounds to aid in finding cars or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it more difficult to keep track of your car keys.
Key fobs utilize radio frequencies to connect with one another and with the programmable car keys. These frequencies are sent by a small antenna in the middle of the key. This signal is encrypted to prevent others from stealing or modifying the signal.
Keyfobs can be programmed in different ways based on the model and make of your vehicle. You may be able to do it yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or additional fob.
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 compared the information with the permitted signals stored in the key fob, and then opens or locks the car's door. If the information does not match, the car will not be allowed to run.
Once the car is linked with a specific fob, it will only accept signals from the device that is associated with it. 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 blocks unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place with the expertise to prepare a replacement fob is in the service department of a dealer. However, some aftermarket fobs that are typically designed for older models that have less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
