This involves changing the chip inside your replacement key to ensure that it matches the current settings on your vehicle. Some manufacturers make it easy, while other require an expert locksmith or dealer.
Self-programming
As the technology of cars has advanced over time, the ignition keys have developed too. The days of simple mechanical keys that you could purchase from the hardware shop for less than $10 are gone. Modern models come with computers that are enhanced security against theft. The cars require a transponder chip-integrated key to be programmed by a professional locksmith mechanic or dealer in order to function properly.
Professional locksmiths can perform a variety of different types of programming for keys to cars. Some are extremely complicated and require sophisticated tools. These tools are generally not available to the general public and are used only by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other types of programming for car keys are much simpler and can be accomplished by the average person. These are done using the onboard diagnostic port, which can be accessed with a special tool for key-fob programming. This method can be done by a locksmith who is trained with the help of an online guide or an owner's manual.
Locksmiths with experience can program a new or replacement car key fob quickly and precisely. This is the best option for car owners as they can offer a wide range of services. They can provide a competitive cost and security of knowing that the replacement key will continue to work.

If you want to save some money, it's a great idea to get a spare key fob that is functional and have it programmed. You can be sure the new key works and is programmed for your car. You'll need to pay the dealer for programming and replacement keys if they don't.
Key Programmers
Modern vehicles require a key-programming process to initialize their vehicle's systems and start the car. In many cases, the key must be set up by the dealer or auto locksmith. This is because the key might not function correctly or start the car at all. The reason is because the new key hasn't been programmed into the vehicle's system, and this could be quite costly. It is best to have two keys that are compatible with your current car so you can program the replacement key if required.
A keyprogrammer is a device which can reprogram the transponder chip into a new key fob or mechanical key. It also can clone data from an existing key in order to create duplicates. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with the computer as well as an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of shapes, sizes and colors. Some are inexpensive and others may cost thousands of dollars. Some are made for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
Check out the owner's manual to learn how to program the key to your vehicle. Some manufacturers use proprietary technology that ensures the dealership is the sole entity that can make new keys. However, other manufacturers make it easy for anyone to do it on their own.
If his explanation are unable to program the new key on your own, then you can request your dealer to do it, however it will be very costly. You can also buy a keyprogrammer on the internet. They're less expensive than going to the dealership however, they're not cheap. Make sure you look up the seller before buying one - some are not reliable and can damage your car.
Transponder Chips
Transponder chips are likely to be found in cars manufactured within the last 20 years. This is a little piece of plastic on the back of your key that contains a RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is positioned around the barrel that controls your ignition in your vehicle. The computer system of the vehicle is then able to verify that the key's transponder chip is the right one for your car.
This stops the vehicle from being started by hot-wiring, or by manipulating. The chip inside the key also verifies that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys with an outer layer of plastic. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a regular cut, a laser cut (also known as a sidewinder key) or Ford Tibbe key.
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 computer on the car recognizes this signal as the right one, it will turn off the vehicle's immobilizer and allow the engine to start.
If the vehicle doesn't recognize the transponder signal as the proper one, it will prevent the engine from running and will notify you by flashing its lights and sounding a siren. This system is designed to deter individuals from tampering with the vehicle. However it's not an absolute security measure. A skilled and determined thief could still be able to bypass this system by employing a device designed to intercept the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all car owners should think about if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the vehicle remotely, make chirping noises to help locate 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 communicate with one other and the car using radio frequencies which are transmitted via an antenna in the center of the key. The transmission is encrypted, which helps stop others from stealing and replicating the signal.
Keyfobs can be programmed in different ways based on the make and model of your car. You can sometimes do this yourself, but most newer vehicles require a locksmith shop or a professional to program a replacement or an additional fob.
When you press the button on a key fob the microchip transmits an indication to the receiver in the vehicle with which it is linked. The receiver compared the information with the 'allowed signals' that are stored in the key fob, and then it opens or closes the car door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't permitted to operate.
Once the car has been paired with a specific fob, it will only accept signals from that device. This means that other fobs will not work with the vehicle, even though they look the same. This helps to protect the integrity of the car's computer system and prevent unauthorised key fobs from taking control of the vehicle.
The majority of newer dealerships will only accept cars that have original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security expertise which can only be obtained in the dealer's service department. However, some aftermarket fobs typically for older models with less sophisticated systems can be programmed by customers without the need for dealers.
