The newer models have computers that have improved anti-theft security. To function properly, these cars require a transponder chip-integrated key be programmed to the vehicle by a certified locksmith or mechanic/car dealer.
Professional locksmiths can perform various types of programming for keys for cars. Certain types are extremely complex and require sophisticated tools. These tools are generally not available to the general public and are only used by professionals. This type of programming is known as EEPROM Programming. It requires expertise in soldering, electronic knowledge and a lot time.
Other kinds of programming car keys are a lot simpler and can be accomplished by anyone who is able to. They are accomplished with the onboard diagnostic port, which is accessible by a specific tool for key fob programming.

This is because the key may not work properly, or it will not start the vehicle at all. This is because the key hasn't yet been programmed into the vehicle's system. This can be expensive. It is recommended to have two keys that work with your current car so you can program the replacement key when needed.
A keyprogrammer is a device that recodes the transponder chip on a new key fob or mechanical key. It can also clone the information from an existing key, allowing duplicates to be created. These are handheld devices that connect to the car's On-Board Diagnostics (OBD) port. They are equipped with diagnostic software that allows them to communicate with computers and also provide a bidirectional interface for working with the immobilizer system.

Transponder Chips
If your car was built within the past 20 years, it is likely that it contains a transponder chip within of it. It's a small piece of plastic inside the head of your key which contains an RFID (Radio Frequency Identification) chip with an individual code for your particular vehicle.
The chip sends out an low-level radio signal once it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of 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 prevents the vehicle from being started through hot-wiring, or by altering the key. The chip inside the key ensures that the owner is the person who is the owner of the vehicle. This can reduce car theft.
Transponder keys appear like normal keys but they have caps made of plastic. The chip is located inside the plastic part of the keys. There are various cuts that are a standard cut, laser cut (also called a sidewinder or Ford Tibbe) and a Ford Tibbe.
When the transponder key is placed in the ignition barrel, a circuit inside of the induction coil will send out the signal. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer onboard the car detects the signal as valid, it will disable vehicle immobilizer so that the engine can start.
If the car doesn't recognize the transponder as being the proper signal, it will not start the engine and will warn you with flashing lights and an alarm. This feature is designed to discourage individuals from tampering with the vehicle. However automotive key programming near me 's not a foolproof measure of security. A skilled and determined criminal may still be able to get around this system using a device that can intercept the signal.
As you can see, there are quite a few advantages to getting a transponder key. All car owners must take this into consideration if they wish to protect their investment and minimize theft risk.
Key Fobs
Key fobs today can do more than just lock and unlock doors. They can also turn on the vehicle remotely, emit chirping sounds to aid in finding a car or switch on the heated steering wheel. These additional features can make it difficult to find your car keys.
Key fobs are able to communicate with each other and with the car through radio frequencies which are transmitted through an antenna in the center of the key. This communication is encrypted, which helps keep others from stealing and retransmitting the signal.
There are a few different ways to program a key fob, based on your vehicle's model and make. It is possible to do this yourself, however most modern automobiles require a dealer or professional locksmith to program a replacement or a second fob.
When you press the button on your key fob, the microchip inside transmits an encoded code to the car's radio that it is linked to. The receiver compares the information with the 'allowed signals' that are stored on the key fob and then it opens or closes the car's doors. If the information doesn't match an chirping sound is heard and the car isn't able to operate.
Once the car has been associated with a particular fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle even though they have the same appearance. This ensures the security of the computer system that runs the car and prevents the use of unauthorized key fobs to gain control of it.
Most newer car dealerships will only work with cars with original fobs or genuine replacements offered by the manufacturer. This is because preparing an appropriate replacement fob requires technical and security skills that is only available in the dealer's service department. Some aftermarket fobs, usually those from older models with less advanced systems can be programmed without the need for a dealer.
