Self-Programming
The ignition keys have developed along with the car technology. The days of simple mechanical keys you could buy from the 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.
Professional locksmiths can carry out various kinds of programming for keys to cars. Certain types are more complex and require advanced tools. These tools are not available to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other types of programming for car keys are much easier and can be performed by the average person. These are done using the onboard diagnostic port, which is accessible with a special tool for key fob programming. A locksmith can perform this method with the assistance of an online guide as well as the owner's manual.

You can be sure the new key will function and is compatible with your car. Otherwise, you will need to pay the dealership for replacement keys and programming services.
Key Programmers
Modern vehicles typically require a key programming procedure to set up the car's system and allow the car to start. In certain instances, the key will need to be programmed by an auto locksmith or dealer. This is because the key might not function correctly, or it will not start the car at all. This is because the new key hasn't been programmed into the vehicle's system - and this can be quite expensive. This is why it's a good idea to have two keys working for a modern automobile, so you can get the replacement key programmed when needed.
A keyprogrammer can recode the transponder chip on the new mechanical key or key fob. It is also able to clone data of an existing key which allows duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.
There are a myriad of types of keyprogrammers available on the market. They are available in a variety of sizes, shapes and colors. Some keyprogrammers are cheap and others can cost thousands of dollar. Certain models are specifically designed for certain kinds of vehicles and can provide advanced diagnostics for the car's electronic systems.
If you want to program an entirely new key for your vehicle, check the owner's manual for instructions on how to do it. Certain manufacturers employ proprietary technology that guarantees that the dealership is the only entity able to create new keys, however other manufacturers make it fairly easy for anyone to do it themselves.
If you are unable to program the new key by yourself and you are unable to do it, then have your dealer do it, but it'll be very costly. You can also buy an online keyprogrammer. They're less expensive than visiting a dealer but they aren't cheap. Make sure you research the seller before purchasing one - some are not reliable and can damage your vehicle.
Transponder Chips
If your car was built in the past 20 years, chances are it contains a transponder chip within of it. This is the little plastic piece in the head of your car key that contains an RFID (Radio Frequency ID) chip with a code unique to your vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is absorbed by a special antenna attached to the ignition barrel. The computer system of the vehicle is then able to verify that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started through hot-wiring or manipulating. The chip inside the key ensures that the owner is the one who is the owner of the vehicle. This can reduce car theft.
Transponder keys look like regular metal keys, but with caps made of plastic. The chip is housed in the plastic portion of the key and there are a few different kinds of cuts available on these keys: a cut, a laser cut (also called a sidewinder key) or Ford Tibbe key.
When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will be received by the chip, causing it to send a signal back to the car. If the computer in the car is able to recognize the signal as correct it will turn off the vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will warn you with flashing lights and a siren. reprogram car key is designed to deter individuals from tampering with the vehicle. However it isn't an absolute security measure. A skilled and determined thief can still get around this system with a specially designed device that intercepts the signal.
As you can see, there are quite a number of advantages to having transponder keys. This is something that all car owners should think about if they are looking to safeguard their investment and minimize 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 aid in finding the car, or turn on the heated steering wheel. A lot of these features may appear convenient but they could make it difficult for you to keep the track of your car keys.
Key fobs communicate with each other and with the car through radio frequencies that are transmitted via an antenna that is located in the middle of the key. The transmission is encrypted, which helps keep others from stealing and re-transmitting the signal.
You can program a keyfob in a variety of ways depending on the model and make of your vehicle. You can sometimes do this yourself, but most 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 an informational code to the car's radio that it is paired with. The receiver compared this information with the 'allowed' signals stored in the fob and then either opens or locks the door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't permitted to function.
After the car has been connected to a specific fob, it will only accept signals from that device. This means that other fobs won't be able to work with the vehicle, even though they appear similar. This ensures the security of the computer system in the car and blocks unauthorized key fobs gaining control over it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security knowledge that is only available in the dealer's service department. However, some aftermarket fobs -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need of dealers.
