There are no more simple mechanical-only keys that could be manufactured at a hardware store for under $10. Modern models come with computers that offer improved security against theft. These cars require a transponder-chip integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly. Professional locksmiths can perform various kinds of programming for keys for cars. Some are complex and require sophisticated tools. These tools aren't generally accessible to the general public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires the ability to solder, electronic skills and a lot of time. Other kinds of programming car keys are much simpler and can be performed by the average person. They are typically done using the onboard diagnostics port which is accessible with the key-fob-programming device. This method can be performed by a locksmith who is trained using an online guide or the vehicle's owner's manual.

This way, you will ensure that the new key is programmed to your vehicle and that it will work. If not, you'll have to pay the dealer for replacement keys and programming services. Key Programmers Modern cars require a key-programming method to initialize their vehicle's systems and to start the car. In some cases the key needs to be programmed by an auto locksmith or dealer. This is because the key may not function properly 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. This is why it's a good idea to always have two working keys for modern vehicles and to have the replacement key programmed if required. A keyprogrammer can reprogram the transponder chip on the new mechanical key or key fob. It is also able to copy the information from an existing key and allow duplicate keys to be made. 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, and they also have an interface that works bidirectionally with the immobilizer system. There are many different types of keyprogrammers available on the market. They come in all sizes, shapes, and colors. Some are cheap and others are advanced and can cost thousands of dollars. Some are specifically designed for certain types of vehicles and can provide advanced diagnostics for the vehicle's electronic systems. Consult your owner's guide to learn how to program the key to your vehicle. Some manufacturers use proprietary technology that makes sure that the dealership is the only entity that can make new keys. However, other manufacturers make it simple for anyone to do it on their own. If you're not able to program a new key yourself, you can ask the dealership to do it for you, but it will cost a lot. You can also buy an online keyprogrammer. They're less expensive than going to a dealership, but still not inexpensive. Make sure you look up the seller before buying one. Some aren't reliable and could harm your vehicle. Transponder Chips Transponder chips are likely to be found in cars that were manufactured within the past 20 years. It's the small plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to the vehicle you own. When it is activated by an electro-magnetic field the chip emits a low level signal. The signal is received by a specific antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the key's transponder chip is the correct one for your car. This is the reason why doing hot-wiring or altering the vehicle's ignition system to start it. The chip in the key also confirms that you are the legal owner of the vehicle. This can reduce car theft. Transponder keys look like regular metal keys but they have a plastic cap. The chip is contained within the plastic portion of the keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe. A circuit inside the induction coil emits a signal when the transponder is put into the ignition barrel. The signal will then get absorbed by the chip and cause it to transmit a signal back to the car. If the computer onboard the car is able to recognize the signal as correct, it will disable vehicle immobilizer, allowing the engine to start. If the vehicle does not recognize the transponder signal as being the right one, it will stop the engine from starting and will alert you by flashing its lights and sounding an alarm. This feature is intended to discourage people from attempting to tamper with the vehicle, however it is not a foolproof security measure. A determined and skilled thief could still evade this system using a special device that blocks the signal. As you can see, there are quite a number of advantages to having a transponder key. All car owners must take this into consideration if they wish to protect their investment and decrease the chance of theft. Key Fobs In addition to locking and unlocking doors, launching the car from a distance or making chirping sounds to help find a car in a parking lot keys of today can also activate the heated steering wheel or roll down all of the windows with a single press. These extra features could make it difficult to locate your car keys. Key fobs are able to communicate with each other and with the car through radio frequencies that are transmitted via an antenna that is located in the center of the key. This communication is encrypted to block other key fobs from intercepting or replicating the signal. You can program a keyfob in different ways based on the model and make of your vehicle. Certain models allow you to do it yourself. However, the majority of modern models require you to visit an expert locksmith or dealer to program a replacement key fob or an additional one. When you hit the button on a key fob, the microchip inside transmits a code to the car's radio that it is paired with. 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 data does not match the signals, the car will not be allowed to operate. Once the car is paired with a specific fob, it will only receive signals from the device that is associated with it. Other fobs will not work with the car, despite the fact that they appear similar. This protects the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle. Most newer car dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because preparing the replacement fob is a process that requires technological and security knowledge that can only be found 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 of a dealership.
