As the technology of cars has advanced throughout the years, ignition keys have evolved too. The days of simple mechanical keys that you could purchase from the hardware shop for less than $10 have gone. The latest models come 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 are able to perform various types of programming for car keys. Some are complex and require sophisticated tools. These tools are usually not accessible to the general public and are used only by professionals. This type of key programming is called EEPROM Programming. It requires soldering skills, electronic knowledge and a lot of time.
Other kinds of key programming can be done by anyone. These are usually done by using the diagnostics port on the car, that can be accessed using the key-fob-programming device. This method can be done by a trained locksmith using an online guide or the vehicle's owner manual.
Professional locksmiths are able to program a replacement or a brand new car key fob quickly. This is the best choice for owners of vehicles as they can offer a full range of services. They can provide a reasonable price and assurance that the replacement key is guaranteed to work.

Key Programmers
Modern automobiles require a key-programming process to set up their systems and to start the car. In certain instances the key will have to be programmed by an auto locksmith or a dealer.

This is why it's a good idea to have two working keys for a modern automobile, so you can get the replacement key programmed when needed.
A keyprogrammer is a tool that recodes the transponder chip on the form of a new mechanical or key fob key. It also can clone the data of an existing key in order to create duplicates. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They are equipped with diagnostic software, which allows them to communicate with a computer. They also have a bidirectional user interface that works with an immobilizer system.

Transponder Chips
If your car is made in the last 20 years, then it contains a transponder chip within of it. It's the small plastic piece in the head of the car key that has an RFID (Radio Frequency ID) chip with a code unique to your car.
When it is 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. The computer system in the vehicle can then verify that the transponder chip of the key is the right one for your car.
This prevents the vehicle from starting by hot-wiring, or by altering the key. The chip inside the key also proves that you are the legitimate owner of the vehicle. This can reduce car theft.
Regular transponder keys are shaped like regular keys, but with an outer layer of plastic. The chip itself is housed within the plastic part of the key, and there are a few different cuts that can be found on these keys: a regular standard cut, a laser cut (also called a sidewinder key), or a Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil sends out the signal. The signal is received by the chip which then transmits a signal the vehicle. If the onboard car computer detects this signal as the right one, it will disable the vehicle's immobilizer and allow the engine to begin.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine and alert you with flashing lights and a siren. This feature is designed to discourage people from tampering with the vehicle. However, it is not a foolproof measure of security. A skilled and determined thief may still be able to escape this security system by using a device that can take over the signal.

Key Fobs

A lot of these features may appear convenient however they could make it more difficult to keep track of your car keys.
Key fobs make use of radio frequencies to connect with one another and with the car. The frequencies are transmitted by a small antenna in the middle of the key. This communication is encrypted, which helps to stop others from stealing and re-transmitting the signal.
Keyfobs can be programmed in various ways based on the make and model of your car. Certain models allow you to do this yourself. However, the majority of modern models require you to visit a professional locksmith or dealer in order to program a replacement key fob or additional one.
When you press the button on a key fob, the microchip transmits a signal to the receiver inside the car with which it is paired. The receiver compared the information with the 'allowed signals' stored in the key fob, and then locks or opens the car's door. If the information does not match the signals, the car will not be allowed to drive.
Once the car has been paired with a specific fob, it will only accept signals from that device. Other fobs won't work with the car, even though they look like. This protects the integrity of the vehicle's computer system and prevent unauthorized key fobs from gaining control of the vehicle.
automotive key programming near me of newer dealers will only work on cars with original fobs or genuine replacements supplied by the manufacturer. This is due to the fact that preparing the replacement fob is a process that requires technological and security expertise which can only be obtained in the dealer service department. Some fobs from the aftermarket, especially those for older models that have less sophisticated systems can be programmed with out the need for a dealership.
