There are no more simple mechanical-only keys that could be manufactured at the hardware store for less than $10. Modern models come with computers that are enhanced security against theft. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith, mechanic or dealer for proper operation. There are many types of car keys programming that can be done by locksmiths who are professionals. Some are complex and require specialized tools. These tools are generally not available to the general public and are used only by professionals. This kind of car key programming is referred to as EEPROM Programming and requires soldering, electronic skills and a lot of time. Other kinds of programming for car keys are much simpler and can be accomplished by the average person. These are done with the onboard diagnostic port, which is accessible with a special tool for key-fob programming. Locksmiths can execute this procedure with the help of an online guide as well as the owner's manual.

Key Programmers Modern automobiles require a key-programming process to start the vehicle's system and to start the car. In certain instances the key needs to be programmed by an auto locksmith or a dealer. The key may not function correctly or will not start the vehicle at all. This is because the new key hasn't been programmed to the automobile's system, and this could be quite costly. This is why it's a great idea to have two working keys for a modern car and have the replacement key programmed when needed. A keyprogrammer can recode the transponder chip on a new mechanical key or key fob. It can also clone information from an existing key to create duplicates. 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 a computer. They also have a bidirectional interface that works with an immobilizer system. There are many different types of keyprogrammers available that are available and they come in all sizes and shapes. Some are inexpensive, while others are very sophisticated and could cost thousands of dollars.

Transponder Chips Transponder chips can be found in cars manufactured in the last 20 years. It's the tiny plastic piece in the head of your car key that houses an RFID (Radio Frequency ID) chip with a unique code for your car. The chip emits an low-level radio signal once it is activated by an electromagnetic field. The signal is received by a specific antenna attached to the barrel of ignition. This allows the vehicle's computer system to verify that the transponder chip inside the key is the correct one for the car you have. This is what stops from modifying or hot-wiring the ignition system of the vehicle to get it started. The chip in the car key verifies that the owner is the one who owns the vehicle. This will help reduce car theft. Transponder keys resemble regular keys made of metal, but with caps made of plastic. The chip is inside the plastic part of the keys. There are several different cuts: a standard cut, Laser cut (also called a sidewinder or Ford Tibbe), and Ford Tibbe. When the transponder key is placed in the ignition barrel, a circuit within of the induction coil will send out the signal. The signal is received by the chip which then transmits a signal to the vehicle. If the onboard car computer recognizes this signal as the right one, it will turn off the immobilizer on the vehicle and allow the engine to begin. If the car doesn't recognize the transponder as the correct signal, it will not start the engine and will warn you with flashing lights and siren. This function is designed to discourage those who would attempt to alter the vehicle. However it's not an unbreakable security measure. car key programmer determined and skilled thief can still get around this system using a special device that blocks the signal. As you can see there are quite few advantages to getting a transponder key. This is something that all car owners should consider if want to safeguard their investment and reduce the chance of theft. Key Fobs Key fobs today offer more than locking and unlock doors. They can also start the vehicle from a distance, make chirping sounds to help locate cars, or switch on the heated steering wheel. These extra features can make it difficult to locate your car keys. Key fobs use radio frequencies to communicate with one another and the car. The frequencies are transmitted via a small antenna that is located in the middle of the key. This communication is encrypted, which helps to keep others from stealing and replicating the signal. There are a few different ways to program a key fob, based on your vehicle's make and model. Certain cars let you do it yourself. However, the majority of modern models require you to visit a professional locksmith or dealer to program a replacement key fob, or an alternative one. When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle that it is paired. The receiver compared this information with the 'allowed' signals stored on the fob and either locks or opens the door. If the data doesn't match an chirping sound is heard and the car isn't permitted to function. Once the car has been paired with a specific fob, it only accepts signals from the device. In turn, other fobs won't work with the vehicle even though they appear similar. This protects the integrity of the computer system in the car and prevents unauthorised key fobs from taking control of it. Most newer car dealers will only work on cars with original fobs or genuine replacements that are supplied by the manufacturer. The reason for this is that the only place that has the expertise to prepare an appropriate replacement fob is a dealer's service department. However, some fobs from the aftermarket -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need for dealers.
