Automotive specialists or locksmiths are typically the ones who re-program car keys. They could take your old key and then use a special tool to program a brand new one for your car.
The process involves reprogramming the chip in your replacement key to match the current settings of your vehicle. Certain manufacturers make it simple, while other require a locksmith or dealer.
Self-programming
The ignition keys have developed as has the technology of cars. There are no more simple mechanical keys that could be manufactured at an hardware store for less than $10. Newer models are equipped with computers that are enhanced 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 a few different types of car key programming that can be accomplished by locksmiths who are professionals. Certain types are extremely complex and require sophisticated tools. These tools are not 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 forms of car key programming are much easier and can be done by the average person. They can be done by with the onboard diagnostic port, which can be accessed via a tool specifically designed for key-fob programming. This procedure can be carried out by a locksmith who is trained with the help of an online guide or an owner manual.
Most professional locksmiths can program a brand new or replacement car key fob fast and precisely. This is the ideal option for car owners since they can offer a full range of services. They can provide a reasonable cost and security of knowing that the replacement key is going to function.
It is important to note that many vehicles will only accept a single key for their system. If you want to save cash, it's a good idea to buy an additional key fob that functions and then program it. This way, you can be sure that the new key has been programmed to your vehicle and that it will work. Otherwise, you will need to pay the dealership for replacement keys and programming services.
Key Programmers
Modern cars require a key-programming method to set up their systems and to start the car. In some instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key could not function properly, or it will not start the vehicle in any way. The reason for this is that the new key hasn't been programmed to the car's system - and this can be very costly. This is why it's a good idea to have two keys working for modern vehicles and to have the replacement key programmed if needed.
A keyprogrammer is a tool that recodes the transponder chip in a new mechanical or key fob key. It is also able to copy the data from an existing key programer which allows duplicate keys to be made. 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 feature a bidirectional user interface for working with an immobilizer system.
There are many various kinds of keyprogrammers that are available, and they come in all shapes and sizes. Some are affordable while others are advanced and could cost thousands of dollars. Some are made for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
Refer to the owner's manual of your vehicle to learn how to program a key for your vehicle. Some manufacturers use proprietary technology that ensures the dealership is the only entity able to create new keys. However, other manufacturers make it easy for anyone to do it themselves.
If you're not able to program a new key yourself, 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 less expensive than visiting a dealership however, they're not cheap. Before you purchase one, do some research on the seller. Some aren't reliable and may damage your vehicle.
Transponder Chips
If your car was manufactured in the last 20 years, chances are it contains a transponder chip within of it. It's a tiny plastic thing inside the head of your key which contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your specific vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets absorbed by the special antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to confirm that the transponder chip in the key is the correct one for the car you have.
This stops the vehicle from being started through hot-wiring, or by tampering. The chip in the key also verifies that you are the legal owner of the vehicle. This will help reduce car theft.
Transponder keys resemble normal keys, but with caps made of plastic. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.
A circuit inside the induction coil will emit signals when the transponder is inserted into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer in the car recognizes the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the vehicle doesn't recognize the transponder as being the proper signal, it won't start the engine and notify you via flashing lights and siren. This system is designed to deter those who would attempt to alter the vehicle. However it's not an unbreakable security measure. A skilled and determined thief could still be able to escape this security system by employing a device designed to take over the signal.
As you can see there are quite a few advantages to getting a transponder key. Every car owner should consider this if they wish to protect their investment and minimize the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also turn on the car from a distance, make chirping sounds to aid in finding a car, or switch on the heated steering wheel. These additional features can make it difficult for you to find your car keys.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted through an antenna that is located in the center of the key. The communication is encrypted, which helps to prevent others from intercepting and replicating the signal.
You can program a keyfob in different ways based on the model and make of your car. You can sometimes do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on your key fob, the microchip inside transmits a code to the car's receiver that it is paired with. 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 doesn't match the fob's information, the car key reprogram won't be allowed to operate.
After the car has been paired with a specific fob, it only accepts signals from the device. This means that other fobs will not work with the vehicle even though they have the same appearance. This protects the integrity of the vehicle's computer system and to prevent unauthorized key fobs from gaining control over the vehicle.
The majority of newer dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place with the experience to design an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for dealers.
