Newer models are equipped with computers that offer improved security against theft. To function properly, these cars require that a transponder chip key be programmed into the vehicle by a certified locksmith or mechanic/car dealer.
automotive key programming can carry out various types of programming for keys for cars. Certain types are more complex and require advanced tools. These tools are not generally accessible to the general public and are used only by professionals. This type of car key programming is known as EEPROM Programming and requires soldering, electronic skills, and a lot of time.
Other forms of car key programming are much simpler and can be done by the average person. They can be done by using the onboard diagnosis port, which is accessible by a specific tool for key fob programming.

Key Programmers
Modern cars require a key-programming procedure to start the vehicle's system and start the car. In many cases the key needs to be programmed by the auto locksmith or dealer. The key might not function properly or it may not even start the vehicle at all. This is because the key has not yet been programmed into the car's system. This could be costly. This is why it's a good idea to always have two keys that work for modern vehicles, so you can get the replacement key programmed when necessary.
A keyprogrammer can reprogram a transponder chip on a new mechanical key or key fob. It can also clone the information from an existing key, allowing duplicates to be made. These devices are handheld units that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that enables them to communicate with computers as well as bidirectional interfaces to work with the immobilizer system.
There are a number of various kinds of keyprogrammers that are available and they come in all sizes and shapes. Some are inexpensive and others are sophisticated and could cost thousands of dollars. Some are made for specific automobiles and provide advanced diagnostics of the car's electronic system.
If you want to program an entirely new key for your vehicle, refer to the owner's manual to learn the procedure. Certain manufacturers have proprietary technology that ensures the dealership is the sole entity able to create new keys. However, other manufacturers make it easy for anyone to accomplish it on their own.
If you are unable to program a new key yourself, you can ask the dealership to program it for you, however this can be expensive. Another option is to buy an online keyprogrammer. These are less expensive than visiting a dealership however they're not cheap. Be sure to look up the seller before buying one - some are not reliable and can damage your car.
Transponder Chips
If your car was built within the past 20 years, then it has a transponder chip inside of it. It's a tiny plastic thing on the back of your key that houses a RFID (Radio Frequency Identification) chip with a unique code for your particular vehicle.
When activated by an electro-magnetic field, the chip emits a low-frequency signal. The signal is then received by a specific antenna that is attached to the ignition barrel. This allows the computer in your vehicle system to determine if the transponder chip that is in the key is the right one for the car you have.
This is what prevents doing hot-wiring or altering the ignition system of your vehicle to get it started. The chip in the key also proves that you are the genuine owner of the vehicle. This can help to 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 different types of cuts on these keys: a regular cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted in the ignition barrel, a circuit within of the induction coil will send out a signal. The signal will then get taken up by the chip, causing it to transmit a signal to the car. If the computer in the car is able to recognize the signal as valid it will turn off the car immobilizer, allowing the engine to start.
If the car does not recognize the transponder signal as being the proper one, it will stop the engine from running and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from tampering with the vehicle. However it's not a foolproof measure of security. A skilled and determined criminal could still be able to escape this security system by using a special device to take over the signal.
As you can see there are quite few advantages to getting transponder keys. This is something that all vehicle owners should consider if want to protect their investment and reduce 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 the car in a parking lot Key fobs today can also activate a heated steering wheel or roll down all windows with a single push. These additional features could make it difficult to find your car keys.
Key fobs make use of radio frequencies to communicate with one another and with the car. These frequencies are sent by a small antenna within the middle of the key. This communication is encrypted to stop others from stealing or modifying the signal.
There are several ways to program a key fob based on the model and make. Some cars allow you to do this by 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 a signal to the receiver inside the car with which it is paired. The receiver compared this information to the 'allowed' signals in the fob and then either opens or closes the door. If the information doesn't match the signals, a chirping sound can be heard and the car isn't allowed to function.
Once the car is linked with a specific fob it will only receive signals from that device. Other fobs won't work with the car, even though they look similar. This is to safeguard the integrity of the vehicle's computer system, and also to stop unauthorised key fobs from taking control over the vehicle.
The majority of newer dealerships will only accept cars that have original fobs or genuine replacements offered by the manufacturer. It is because the only place with the experience to design an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by consumers without the need of an authorized dealer.
