Self Programming
As the technology of cars has advanced over the years, the ignition keys have also evolved as well. The days of the basic mechanical keys you could make at a hardware shop for less than $10 are gone. The newer models have computers that have improved anti-theft security. To function properly, these cars require a transponder chip-integrated key be programmed into the vehicle by a professional locksmith or mechanic/car dealer.
Professional locksmiths can carry out various types of programming for keys for cars. Some are complex and require sophisticated tools. These tools aren't generally available to the public and are only used by professionals. This type of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other forms of programming for car keys are much simpler and can be performed by the average person. They are accomplished with the onboard diagnostic port, which is accessible with a special tool for key-fob programming. This method can be done by a trained locksmith using an online guide or an owner's manual.
Locksmiths with experience can program a brand new or replacement car key fob quickly and accurately. This is the best choice for car owners since they are able to provide a full range of services.

You'll have to pay the dealer for programming and replacement keys if you don't.
Key Programmers
Modern vehicles require a key-programming method to start the vehicle's system and to start the car. In some instances the key will have to be programmed by an auto locksmith or a dealer. This is because the key might not function correctly, or it will not start the car at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. This is why it's a great idea to have two working keys for a modern car and to have the replacement key programmed when needed.
A keyprogrammer can recode the transponder chip of the new mechanical key or key fob. It can also clone the information from an existing key, allowing duplicates to be made. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They have diagnostic software that enables them to communicate with the computer and also provide a bidirectional interface for working with the immobilizer system.
There are a number of various kinds of keyprogrammers that are available and they come in a variety of shapes and sizes. Some keyprogrammers are cheap and others can cost thousands of dollar. Some are made for specific vehicles and can provide advanced diagnostics of the vehicle's electronic system.
If you're interested in programming the new key into your vehicle, check the owner's manual to find out how to do it. Certain manufacturers employ proprietary software that allows only dealers to make new keys. Other manufacturers make it easy for anyone to do.
If you're unable to program a new key yourself You can request the dealer to do it for you, however it will cost a lot. Another option is to purchase a keyprogrammer online. They are less expensive than visiting a dealer however, they aren't inexpensive. Be sure to look up the seller before buying one. Some aren't reliable and can damage your vehicle.
Transponder Chips
If your car was manufactured within the past 20 years, it is likely that it contains a transponder chip within of it. It's a tiny plastic piece in the head of your key that houses a RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low level signal. The signal is then taken up by the antenna that is attached to the barrel that controls your ignition in your vehicle. This allows the vehicle's computer system to confirm that the transponder chip that is in the key is the correct one for your specific vehicle.
This stops the vehicle from being started by hot-wiring or tampering. The chip inside the key also proves that you are the legitimate owner of the vehicle. This will help reduce car theft.
Regular transponder keys are designed like regular metal keys with a plastic top. The chip is inside the plastic portion of these keys. There are a variety of cuts such as a standard cut Laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out an electrical signal. The signal is received by the chip which then transmits a signal to the vehicle. If the computer onboard the car recognizes the signal as being correct it will turn off the vehicle immobilizer to allow the engine start.
If the vehicle doesn't recognize the transponder as the correct signal, it will not start the engine and warn you with flashing lights and an alarm. This feature is intended to deter people from trying to alter the vehicle, but it isn't a foolproof security measure. A skilled and skilled criminal can still get around 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. This is something that all vehicle owners should consider if they want to protect their investment and minimize the risk of theft.
Key Fobs
In addition to locking and unlocking doors, starting the car remotely or making sound chirps to help locate a car in a parking space keys of today can also turn on a heated steering wheel, or roll down all of the windows with a single press. These additional features can make it difficult for you to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and the car. These frequencies are transmitted via a small antenna that is located within the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal.
Keyfobs can be programmed in different ways based on the model and brand of your car. You may be able to do it yourself, however most modern cars require that you visit an expert locksmith or dealer to program a replacement or an additional fob.
When you press the button on a key fob the microchip sends signals to the receiver inside the car with which it is linked. The receiver compared the information with the 'allowed signals' stored in the key fob and then it opens or closes the car's doors. If the data doesn't match, a chirping sound is heard and the car isn't allowed to operate.
Once the car is linked with a specific fob it will only accept signals from the device that is associated with it. This means that other fobs won't be able to work with the vehicle even if they have the same appearance. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
The majority of car dealers who are newer will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. It is because the only place that has the knowledge to create a replacement fob is in the service department of a dealer. However, car key programming from the aftermarket that are typically designed for older models with less sophisticated systems -- can be programmed by customers without the need for dealers.
