To function correctly, these vehicles require that a transponder chip key be programmed into the vehicle by a certified locksmith or car dealer/mechanic.
There are a few different types of car key programming that can be done by locksmiths who are professionals. Some are extremely complicated and require sophisticated tools. These tools aren't generally available to the public and are utilized only by professionals. This kind of programming is referred to as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.
Other types of key programming can be done by anyone. They are typically accomplished by using the diagnostics port on the car, which is accessible with a special key-fob-programming tool. A locksmith can perform this method with the assistance of an online guide as well as the owner's manual.

This is because the new key hasn't been programmed to the car's system. This can be quite costly. It is best to have two keys that are compatible for your modern car so you can program the replacement key when required.
A keyprogrammer is a tool which can reprogram the transponder chip on a new key fob or mechanical key. It is also able to copy 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 come 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 programming car key of keyprogrammers available on the market. They are available in a variety of shapes, sizes and colors.

Transponder Chips
Transponder chips can be found in cars manufactured within the last 20 years. This is a little plastic thing in the head of your key which contains an RFID (Radio Frequency Identification) chip with a unique code for your specific vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. The signal is then amplified by the specific antenna that is fitted around the ignition barrel of your vehicle. This allows the vehicle's computer system to confirm that the transponder chip in the key is the correct one for your specific vehicle.
This prevents the vehicle from starting by either hot-wiring or by manipulating. The chip in the car key confirms that the owner is the one who owns the vehicle. This will help reduce car theft.
Transponder keys look like regular keys made of metal but they have caps made of plastic. The chip is contained in the plastic portion of the key and there are different cuts that can be found on the keys: a cut laser cut (also called a sidewinder key) or Ford Tibbe key.
A circuit inside the induction coil will emit signals when the transponder is put into the ignition barrel. The signal is received by the chip which then transmits a signal the vehicle. If the computer on the car recognizes this signal as the right one, it will shut down the vehicle's immobilizer and allow the engine to start.
If the car does not recognize the transponder signal as being the correct one, it will keep the engine from starting and will alert you by flashing its lights and sounding a siren. This feature is designed to discourage people from trying to tamper with the vehicle, but it is not a foolproof security measure. A skilled and determined thief may still be able to escape this security system by employing a device designed to take over the signal.
As you can see there are quite a number of benefits to having transponder keys. All car owners should take this into consideration if they wish to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today can offer more than locking and unlock doors. They can also start the car remotely, make chirping noises to aid in finding the car, or turn on the heated steering wheel. Many of these extra features may appear convenient however they could make it more difficult to keep the track of your car keys.
Key fobs are able to communicate with each with the car via radio frequencies that are transmitted by an antenna in the center of the key. The signal is encrypted to block other key fobs from intercepting or replicating the signal.
Keyfobs can be programmed in various ways based on the make and model of your vehicle. You can sometimes do this yourself, however most modern vehicles require a locksmith shop or a professional to program a replacement or a second fob.
When you press a key fob's button, the microchip inside transmits an informational code to the car's radio that it is linked to. The receiver then compares the data with the permitted signals stored in the key fob, and then it opens or closes the car's door. If the information doesn't match, the car will not be allowed to operate.
When a car is connected with a specific fob it will only receive signals from that specific device. Other fobs won't work with the car, even though they appear like. This protects the integrity of the vehicle's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealers will only work on a car with original fobs or genuine replacements that are supplied by the manufacturer. It is because the only place that has the knowledge to create an appropriate replacement fob is a dealer's service department. Some fobs from the aftermarket, especially those for older models with less advanced systems can be programmed with out the need for a dealership.
