This requires reprogramming the new key's transponder to match the settings of the car that was originally programmed.
Some cars allow you to do it yourself, however most require a professional or dealer to use a tool to connect to the vehicle and read the programming information from the ECU. Then, the key will be changed to match the car's settings and you are able to use it as an ordinary key.
There are many different types of car key programmers, some of which are designed for specific makes and models of vehicles some are more universal and can be used on a range of automobiles. The majority of these devices have an LCD display with a few buttons to switch between programming modes. After that, you can plug the device into the OBD-II port to begin reading and programming the new key.
Professionals can program a new car key in just several seconds, but some vehicles require more time and intricate methods to reprogram keys correctly.

Key Fobs
Modern-day key fobs offer numerous convenience and security benefits. They replace or supplement traditional car keys and can be used to control more than just locking doors; they can start the engine, trigger the alarm, and perform other functions.
The key fob utilizes radio signals to communicate with a receiver that is installed in the vehicle. When you hit a button on the key fob, it sends a code to the receiver, which responds by performing the desired function. Commercial building owners also utilize key fobs as they allow them to integrate them into an entire system of access control. This lets them track who enters or leaves and they can stop fobs that have been taken or lost.
Key fobs, like any electronic device, could malfunction. They can be damaged or lose their signal when they are jostled in pockets and purses. While they can withstand a lot of abuse, they aren't indestructible. After all, they are made from plastic and metal.
If your key fobs don't working, you may need to replace the battery. Make sure to use the correct battery, and refer to your owner's manual for instructions on how to replace it properly. Be sure to follow all additional steps that may be required for reprogramming and recalibration.
Simple wear and tear is a second common cause of failing fobs. When they are constantly dropped, pushed into objects, and jostled about in pocket and purses they can wear down or even cracked. A simple and affordable fix can often be all that's needed to restore your keyfobs to working order.

Keyless Entry
Keyless entry allows you to open and start your car without having to insert the physical key. It utilizes wireless signals to communicate with the car's internal system, and also allows you to control different features in the vehicle, such as climate controls or music systems.
Modern keyless entry systems utilize rolling code technology to guard against hacking and other security breaches. However, it's important to keep in mind that even this technology has its limitations. Using a technique called "replay attack," thieves can make use of the transmitter on the key fob to send a message that is recorded by the car's receiver. After the message has been recorded, a malicious device could retransmit the message to the vehicle's receiver and gain access.
Depending on the make and model of your vehicle, you may be capable of programming new keys yourself, or you may have to employ an automotive locksmith to do it. Certain car manufacturers offer an onboard program that is specifically designed for their vehicles, while others require you have a sophisticated programmer connected to the OBD2 connector.
The most commonly used method to program new keys for cars is to insert the fob of the key in the ignition and turn it on in a specific order. This puts the car in the "programming mode," and once it is activated, one or more fob buttons are pressed to transmit the digital identity code to the computer in the car. The computer stores the code and takes the car from the programming mode.
Some manufacturers require you to have an advanced programer to program key fobs, and some of them are costly and difficult to use for a common person. It is best to leave the work to an automotive locksmith or dealer.
To set up for a car with keyless entry, enter your vehicle from the driver's seat. Then close all the doors, with the exception of the driver's. This will stop the system from locking the doors while you're trying to program the key. Press and hold the button on the fob you want to activate while the ignition is on and the other keys you wish to be programmed nearby. The hazard light will flash twice.
