The process involves reprogramming the blank chip inside the replacement key to match the current settings of your vehicle. Certain manufacturers make this process simple but others require a dealer or locksmith.
Self-Programming
As car technology has evolved over the years, the ignition keys have developed as well. Gone are the days of simple mechanical keys that could be manufactured at the hardware store for less than $10. Modern models come with computers that offer improved anti-theft protection. These cars require a transponder-chip-integrated key to be programmed by a professional locksmith car dealer or mechanic for proper operation.
Professional locksmiths can perform various types of programming for keys to cars. Some are very complex and may require advanced tools. These tools are usually not available to the general public and are only used by professionals. This kind of programming is referred to as EEPROM Programming. It requires soldering skills, electronic knowledge and a significant amount of time.
Other types of key programming can be performed by anyone. They are typically done using the onboard diagnostics port that can be accessed using an instrument for programming keys. This procedure can be carried out by a professional locksmith using an online guide or an owner manual.
Professional locksmiths can program a replacement or new car key fob quickly. This is the best choice for car owners since they are able to provide a wide range of services. They can provide a reasonable rate and the assurance that the replacement key is guaranteed to function.

This way, you will ensure that the new key is programmed for your vehicle and that it will work. Otherwise, you will need to pay the dealer for replacement keys and programming services.
Key Programmers
Modern vehicles frequently require a key programming process to start the system of the vehicle and allow the car to begin. In some cases, the key will need to be programmed by an auto locksmith or dealer. The key might not function properly or it may not even start the car in any way. This is because the key hasn't yet been programmed into the car's system. This could be costly. It is best to have two keys that are compatible for the modern automobile so that you can program the replacement key whenever needed.
A keyprogrammer is a tool that can recode the transponder chip into an entirely new key fob or mechanical key. It can also clone the data of an existing key in order to create duplicates. These are handheld devices that connect to the 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 interface that works with an immobilizer system.
There are many different types of keyprogrammers on the market. They come in all shapes, sizes and colors. Some keyprogrammers are cheap while others can cost thousands of dollar. Certain are designed for specific automobiles and offer advanced diagnostics of the car's electronic system.
If you want to program a new key to your vehicle, refer to the owner's manual for instructions on how to do it. Some manufacturers use proprietary software that only allows the dealership to create new keys. Other manufacturers make it easy for anyone to do.
If you're not able to program a new key by yourself, you can request the dealer to program it for you, but this will be very expensive. Another option is to buy a keyprogrammer online. They're less expensive than visiting a dealer, but still not inexpensive. Make sure you research the seller before purchasing one - some are not reliable and could damage your vehicle.
Transponder Chips
Transponder chips are likely be found in cars manufactured in the last 20 years. It's the small plastic piece inside the head of your car key that contains an RFID (Radio Frequency ID) chip with a unique code for your vehicle.
When it is activated by an electro-magnetic field, the chip emits a low-level signal. This signal then gets taken up by the antenna that is positioned around the ignition barrel of your car. The computer system of the vehicle will then confirm that the key's transponder chip is the right one for your car.
This is what prevents doing hot-wiring or altering the ignition system of the vehicle to start it. The chip inside the key also confirms that you are the legitimate owner of the vehicle. This will help reduce car theft.
Transponder keys resemble regular keys made of metal but they have caps made of plastic. The chip is inside the plastic portion of these keys. There are various cuts that are a standard cut, laser cut (also known as a sidewinder or Ford Tibbe) and the Ford Tibbe.
The circuit in the induction coil will emit signals when the transponder is placed in the ignition barrel. The signal will then get absorbed by the chip and cause it to send a signal back to the car. If the computer inside the car is able to recognize the signal as correct it will turn off the car immobilizer to allow the engine start.
If the car doesn't recognize the transponder as the correct signal, it won't start the engine, and will warn you with flashing lights and siren. This system is designed to deter people from tampering with the vehicle. However, it is not an unbreakable security measure. A determined and skilled thief can still get around this system using a special device that blocks the signal.
It is evident that the transponder is an excellent option. This is something that all car owners should consider if want to protect their investment and decrease the chance of theft.
Key Fobs
In addition to locking and unlocking doors, launching the car from a distance or making noises to aid in finding a car in a parking lot Key fobs today can also switch on a heated steering wheel or open all windows with a single button click. These extra 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. The signal is encrypted to prevent others from intercepting or replicating the signal.
There are many ways to program a key fob based on your vehicle's model and make. Certain models allow you to do it 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 an additional one.
When you press the button on a key fob, the microchip sends signals to the receiver inside the car with which it is paired. The receiver compares this information with the 'allowed' signals stored inside the fob, and either locks or opens the door. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car is associated with a particular fob, it will only accept signals from that device. This means that other fobs won't be able to work with the vehicle even if they appear similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorized key fobs from gaining control over the vehicle.
Most dealerships with newer cars will only work with vehicles that have original fobs, or genuine replacements supplied by the manufacturer. This is because the process of creating a replacement fob requires technological and security knowledge that can only be found in the dealer's service department. However, key programmer -- usually those for older models with less sophisticated systems can be programmed by the consumer without the need of a dealership.
