Self-programming
The ignition keys have changed as has the technology of cars. Gone are the days of simple mechanical keys that were made at the hardware store for less than $10. The latest models come with computer systems that are more secure 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 key programming that can be performed by locksmiths who are professionals. Certain types are extremely 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 car key programming is referred to as EEPROM Programming and requires soldering, electronic skills, and a lot of time.
Other types of key programming can be performed by anyone. These are done using the onboard diagnosis port, which is accessible by a specific tool for key-fob programming. This method can be done by a trained locksmith with the help of an online guide or the car's owner's manual.

You can be certain that the new key will function and is programmed for your car. You'll need to pay the dealer for programming and replacement keys if you don't.
Key Programmers
Modern vehicles often require a key programming process to start the system of the vehicle and allow the vehicle to begin. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key might not function properly or it may not even start the vehicle in any way. This is because the key has not yet been programmed into the car's system. This could be costly. It's best to have two keys that work for your modern car so you can program the replacement key when required.
A keyprogrammer can reprogram the transponder chip on a new mechanical key or key fob. It also can clone the data of an existing key to make duplicates. These are handheld devices that connect to a car's On Board Diagnostics (OBD port). They have diagnostic software that enables them to communicate with computers, and they also have an interface that works bidirectionally with the immobilizer system.
There are a myriad of types of keyprogrammers that are available on the market. They are available in a variety of shapes, sizes and colors. Certain keyprogrammers are affordable while others could cost thousands of dollars. Some are specifically designed for certain types of vehicles and can offer advanced diagnostics for the car's electronic systems.
Consult your owner's guide to learn how to program a key for your vehicle. Certain manufacturers have proprietary software that only permits dealers to create new keys. Other manufacturers make it simple for anyone to complete.
If you're not able to program a new key on your own, you can request the dealer to do it for you, however this will be very expensive. Another option is to purchase an online keyprogrammer. They are less expensive than visiting a dealer but they aren't expensive. Before purchasing automotive key programming do some research on the seller. Some aren't trustworthy and may damage your vehicle.
Transponder Chips
Transponder chips are likely to be found in cars that were manufactured within the past 20 years. It's a tiny piece of plastic on the back of your key that houses an RFID (Radio Frequency Identification) chip with a unique code for the specific vehicle you own.
The chip sends out an unintentional radio signal when it is activated by an electromagnetic field. The signal is received by a specific antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to confirm that the transponder chip that is in the key is the correct one for your particular car.
This is the reason why doing hot-wiring or altering the vehicle's ignition system to get it started. The chip inside the key ensures that the owner is the one who is the owner of the vehicle. This helps to prevent car theft.
Regular transponder keys are designed like regular metal keys with an outer layer of plastic. The chip itself is housed inside the plastic portion of the key and there are different kinds of cuts available on the keys: a standard cut, a laser cut (also known as a sidewinder key), or a Ford Tibbe key.
The circuit in the induction coil emits signals when the transponder is put into the ignition barrel. The signal is taken up by the chip, which sends a signal to the vehicle. If the computer on the car recognizes this signal as the correct one, it will shut down the vehicle immobilizer and allow the engine to begin.
If the vehicle doesn't recognize the transponder as a valid signal, it will not start the engine and will alert you with flashing lights and a siren. This function is designed to discourage individuals from tampering with the vehicle. However, it is not a foolproof measure of security. A determined and skilled thief could still evade this system using a special device that blocks the signal.
As you can see there are quite a number of advantages to having transponder keys. This is something that all vehicle owners should consider if they want to protect their investment and decrease the risk of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start your vehicle from a distance, make chirping sounds to help locate cars or turn on the heated steering wheel. Many of these extra features might seem useful but they could make it more difficult to keep the keys to your car.
Key fobs are able to communicate with each with the car via radio frequencies which are transmitted via an antenna in the middle of the key. This communication is encrypted, which helps to prevent others from intercepting and re-transmitting the signal.
Keyfobs can be programmed in a variety of ways depending on the make and model of your vehicle. Certain cars let you do it yourself. However, programming car key require you to visit a professional locksmith or dealer to program a replacement key fob or an additional one.
When you press a key fob's button it transmits an encoded code to the car's radio that it is linked to. The receiver compared this information with the signals that are allowed inside the fob, and either locks or opens the door. If the information doesn't match the fob's information, the car won't be allowed to run.
After the car has been paired with a specific fob, it can only receive signals from that device. In turn, other fobs won't be able to work with the vehicle, even though they look the same. This ensures the security of the computer system of the vehicle and stops unauthorised key fobs from taking control of it.
Most newer car dealerships will only work with cars that have original fobs or genuine replacements sold by the manufacturer. It is because the only place that has the experience to design an appropriate replacement fob is the service department of a dealer. However, some aftermarket fobs -- usually those for older models that have less sophisticated systems -- can be programmed by consumers without the need for an authorized dealer.
