Self Programming
As the technology of cars has advanced over time, the ignition keys have also evolved as well. The days of simple mechanical-only keys that were made at the hardware store for less than $10. Newer models are equipped with computers that offer improved security against theft. To function correctly, these vehicles require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
There are a few different types of car key programming that can be performed by locksmiths who are professionals. Some are very complex and require sophisticated tools. These tools aren't usually available to the public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires the ability to solder, electronic skills and a lot time.
Other kinds of key programming can be carried out by anyone. These are done using the onboard diagnosis port, which can be accessed via a tool specifically designed for key fob programming. A locksmith can perform this method with the assistance of an online guide and the owner's manual.
Locksmiths with experience can program a new or replacement car key fob swiftly and accurately. This is the best option for vehicle owners as they can offer a full range of services. They can also offer an affordable cost and assurance that the replacement key will work correctly.

This way, you can ensure that the new key is programmed to your vehicle and that it will work. In the event that it doesn't, you'll need to pay the dealership for replacement keys and programming services.
Key Programmers
Modern vehicles often require a key programming process to set up the car's system and allow the vehicle to begin. In some instances keys must be programmed by the dealer or auto locksmith. The key might not function properly or not start the vehicle in any way. The reason is because the new key hasn't been programmed into the vehicle's system, and this could be very costly. It is best to have two keys that work with your current car so you can program the replacement key whenever required.
A keyprogrammer is a tool that can recode the transponder chip in an entirely new key fob or mechanical key. It is also able to copy the information from an existing key and allow duplicate keys to be made. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They come with diagnostic software, which 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 on the market. They are available in a variety of shapes, sizes and colors. Some are affordable and others are advanced and could cost thousands of dollars. Some are designed for specific kinds of vehicles, and they can even offer advanced diagnostics for the vehicle's electronic systems.
Check out the owner's manual to learn how to program the key to your vehicle. Certain manufacturers employ proprietary technology that ensures the dealership is the only entity that can make new keys, but other manufacturers make it easy for anyone to accomplish it on their own.
If you're unable to program the new key yourself and you are unable to do it, then ask your dealer to do it, but it'll cost a lot. You can also buy an online keyprogrammer. They're less expensive than visiting a dealer, but still not cheap. Be sure to look up the seller before buying one. Some aren't reliable and can damage your vehicle.
Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. This is the little piece of plastic in the head of your car key that houses an RFID (Radio Frequency ID) chip that has a unique code to your car.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is then received by a specific antenna that is attached to the barrel of ignition. The computer system in the vehicle will then confirm that the chip in the key's transponder is the correct one for your car.
This stops the vehicle from being started by hot-wiring or manipulating. The chip inside the key also verifies that you are the genuine owner of the vehicle. This can reduce car theft.
Transponder keys look like regular keys made of metal but have a plastic cap. The chip is contained within the plastic portion of the keys. There are a variety of cuts such as a standard cut laser cut (also known as a sidewinder or Ford Tibbe) and Ford Tibbe.
A circuit within the induction coil will emit an electrical signal when the transponder is placed in the the ignition barrel. The signal will then get absorbed by the chip, causing it to transmit a signal to the car. If the computer inside the car detects the signal as valid it will turn off the vehicle immobilizer, allowing the engine to start.
If the car isn't able to recognize the transponder as a valid signal, it won't start the engine and will warn you with flashing lights and siren. This feature is designed to discourage people from attempting to tamper with the vehicle, but it isn't a foolproof security measure. A skilled and committed thief may still be able to bypass this system by employing a device designed to detect the signal.
As you can see, there are quite a few advantages to getting a transponder key. Every car owner must take this into consideration in order to safeguard their investment and reduce the risk of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start your car remotely, make chirping noises to help locate the car or switch on the heated steering wheel. Many of these extra features may appear convenient, but they can also make it harder 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 in the middle of the key. This communication is encrypted to block other key fobs from stealing or modifying the signal.
There are several ways to program a key fob depending on the vehicle's model and make. It is possible to do this yourself, but the majority of newer automobiles require a locksmith shop or a professional to program a replacement or a second fob.
When you press the button on a key fob the microchip transmits signals to the receiver in the vehicle with which it is paired. The receiver compares the information with the 'allowed signals' stored in the key fob and then opens or locks the car door. If the information isn't in line the signals, a chirping sound can be heard and the car isn't able to function.
Once the car is associated with a particular fob, it will only accept signals from that device. Other fobs won't work with the car, despite the fact that they look similar. This helps to protect the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control of the vehicle.
Most dealerships with newer cars will only accept vehicles that have original fobs, or genuine replacements sold by the manufacturer. This is due to the fact that preparing a replacement fob requires technological and security knowledge that is only available in the dealer service department. Certain aftermarket fobs, typically those from older models with less advanced systems can be programmed without the need for a dealership.
