Newer models are equipped with computers that have improved anti-theft protection. To function correctly, these vehicles require that a transponder chip key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.

Professional locksmiths can perform various kinds of programming for keys to cars. Some are complex and require specialized tools. These tools aren't usually available to the public and are utilized only by professionals. This kind of programming for car keys is known as EEPROM Programming and requires soldering, electronic skills and a lot of time.

Other forms of car key programming are a lot simpler and can be done by anyone who is able to. They are typically done 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.

Key Programmers

Modern vehicles typically require a key programming procedure to initialize the vehicle's system and allow the car to start. In a number of cases keys must be programmed by the auto locksmith or dealer. The key might not function correctly or will not start the vehicle at all. The reason for this is that the new key hasn't been programmed to the car's system, and this could be quite 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 required.

Keyprogrammers are devices that recodes the transponder chip into an entirely new mechanical or key fob key. It can also clone the data of an existing key and allow duplicate keys to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers. They also have a bidirectional interface to work with an immobilizer system.

There are many various kinds of keyprogrammers on the market and they are available in a variety of shapes and sizes. Some are cheap, while others are very sophisticated and can cost thousands of dollars. Certain models are specifically designed for vehicles and can provide advanced diagnostics of the vehicle's electronic system.

If you're interested in programming a new key to your vehicle, check the owner's manual to learn how to do it. 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 do it themselves.

If you are unable to program a new key on your own or ask the dealership to program it for you, but this will be very expensive. Another option is to purchase an online keyprogrammer. They're less expensive than going to a dealership but they aren't expensive. Make sure you investigate the seller prior to purchasing one - some are not reliable and can damage your car.

Transponder Chips

If your car is made within the last 20 years, it is likely that it has a transponder chip inside of it. It's a small piece of plastic in the head of your key which contains an 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 is then absorbed by a special antenna attached to the barrel of ignition. This allows the computer in your vehicle system to determine if the transponder chip in the key is the right one for your specific vehicle.

This is what stops doing hot-wiring or altering the ignition system of your vehicle to start it. The chip in the key also confirms that you are the genuine owner of the vehicle. This can reduce car theft.

Regular transponder keys are shaped like regular keys and have an outer layer of plastic. The chip is located inside the plastic portion of the keys. There are a variety of cuts that are a standard cut, a Laser cut (also called a sidewinder or Ford Tibbe) and the Ford Tibbe.

The circuit in the induction coil emits a signal when the transponder is placed in the the ignition barrel. The signal is taken up by the chip, which then transmits a signal the vehicle. If the computer on the car detects this signal as the right one, it will disable the immobilizer on the vehicle and allow the engine to start.

If the car does not recognize the transponder signal as the proper one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This is designed to discourage people from attempting to hack into the vehicle, but it's not a 100% security measure. A skilled and determined criminal may still be able to escape this security system by using a device that can intercept the signal.

As you can see there are quite a few advantages to getting a transponder key. All car key programming and cutting owners must take this into consideration when they want to safeguard their investment and reduce the chance of theft.

Key Fobs

Key fobs today can be more than just a way to lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to help locate cars or turn on the heated steering wheel. A lot of these additional features might seem useful however they could make it difficult for you to keep the keys to your car.

Key fobs communicate with one with the car via radio frequencies which are transmitted by an antenna that is located in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and retransmitting the signal.

There are a few different ways to program a key fob, based on your vehicle's make and model. Some cars allow you to do this by yourself. However, the majority of newer models require you to visit an expert locksmith or dealer to program a new key fob or an additional one.

When you hit the button on a key fob it transmits a code to the car's radio that it is linked to. The receiver compares this information to the 'allowed' signals on the fob and either opens or closes the door. If the information does not match, the car will not be allowed to drive.

Once the car has been associated with a particular fob, it only accepts signals from that device. Other fobs will not work with the car, despite the fact that they look identical. This protects the integrity of the computer system of the car and blocks the use of unauthorized key fobs to gain control of it.

The majority of newer dealerships will only deal with vehicles that have original fobs or genuine replacements offered by the manufacturer. The reason for this is that the only place with the expertise to prepare an appropriate replacement fob is the service department of a dealer. However, some fobs from the aftermarket that are typically designed for older models that have less sophisticated systems -- can be programmed by consumers without the need for a dealership.
