The latest models come with computers with improved anti-theft protection. These cars require a transponder-chip integrated key to be programmed by a professional locksmith car dealer or mechanic to function properly.
Professional locksmiths can perform a variety of different types of programming for keys for cars. Some are extremely complicated and may require advanced tools. These tools are usually not accessible to the general public and are only used by professionals. This kind of key programming is called EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot of time.

Key Programmers
Modern automobiles frequently require a key programming process to start the system of the vehicle and allow the car to begin. In certain instances the key will have to be programmed by an auto locksmith or a dealer. The key may not work properly or it may not even start the vehicle in any way. This is because the key has not yet been programmed into the vehicle's system. This can be expensive. This is why it's a good idea to have two keys that work for a modern car and to have the replacement key programmed if required.
A keyprogrammer is a tool that can recode the transponder chip on an entirely new key fob or mechanical key. reprogram car key is also able to copy the data of an existing key which allows duplicate keys to be made. These are handheld devices connected to a car's On Board Diagnostics (OBD port). They come with diagnostic software that allows them to communicate with the computer as well as a bidirectional interface for working with the immobilizer system.

Certain models are specifically designed for certain types of vehicles and provide advanced diagnostics for your vehicle's electronic systems.

They are less expensive than visiting a dealer but they aren't expensive. Before purchasing one do some research on the seller. Some are not reliable and may damage your vehicle.
Transponder Chips
If your car is made in the past 20 years, it is likely that it has a transponder chip inside of it. It's a small plastic thing in the head of your key that contains a RFID (Radio Frequency Identification) chip with a unique code that is specific to your particular vehicle.
When it is activated by an electromagnetic field, the chip emits a low-level signal. This signal then gets absorbed by the special antenna that is fitted around the barrel that controls your ignition in your car. This allows the vehicle's computer system to determine if the transponder chip inside the key is the right one for your specific vehicle.
This is the reason why hot-wiring or tampering with the ignition system of your vehicle to start it. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This will help reduce car theft.
Regular transponder keys are shaped like regular metal keys with a plastic top. The chip is housed in the plastic portion of the key, and there are different cuts that can be found on these keys: a standard cut, a laser cut (also called a sidewinder) or Ford Tibbe key.
When the transponder key is inserted into the ignition barrel, a circuit inside of the induction coil will send out the signal. automotive key programming is received by the chip which then transmits a signal the vehicle. If the computer in the car detects the signal as valid it will turn off the vehicle immobilizer to allow the engine start.
If the car does not recognize the transponder signal as being the correct one, it will stop the engine from running and will notify 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 an unbreakable security measure. programming car key and determined 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. This is something that all car owners should consider if they want to protect their investment and reduce the chance of theft.
Key Fobs
Key fobs today do more than just lock and unlock doors. They can also start the vehicle from a distance, make chirping sounds to help locate cars or turn on the heated steering wheel. A lot of these features may appear convenient, but they can also make it more difficult to keep the track of your car keys.
Key fobs are able to communicate with each other and the car using radio frequencies that are transmitted by an antenna that is located in the center of the key. This signal is encrypted to block other key fobs from intercepting or replicating the signal.
You can program a keyfob in various ways based on the model and brand of your vehicle. You can sometimes do this yourself, but most newer automobiles require an expert locksmith or dealer to program a replacement or an additional fob.
When you hit the button on a key fob the microchip inside sends an informational code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' that are stored in the key fob, and then locks or opens the car's doors. If the information does not match the signals, the car will not be allowed to drive.
Once the car is linked with a specific fob it will only accept signals from that specific device. Other fobs won't work with the car, despite the fact that they appear similar. This protects the integrity of the computer system that runs the car and prevents unauthorised key fobs from taking control of it.
The majority of newer dealers will only work on cars with original fobs or genuine replacements that are offered by the manufacturer. This is due to the fact that preparing an appropriate replacement fob requires technical and security knowledge which can only be obtained in the dealer service department. Some aftermarket fobs, usually ones for older models that have less advanced systems, can be programmed without the need for a dealer.
