This involves reprogramming your new key's transponder to match the settings of the original car.
Some vehicles allow you to do it yourself, but most require a professional dealer to utilize a tool that is able to connect to the vehicle and read the programming data from the ECU. Then, the key will be changed to match the car's setting and you can use it as an ordinary key.
There are numerous kinds of car key programmers, some of which use specific brands and models of vehicles some are more universal and can be used on a wide range of vehicles. The majority of these devices come with a small display and a number of buttons that you press to enter the programming mode. You can then connect the device to an OBD-II connector to read and programm the new key.
Professionals can program a new car key in just a few seconds, but certain vehicles require longer and complicated procedures to reprogram keys correctly.

Key Fobs
Modern key fobs offer many conveniences and security advantages. They can replace or supplement traditional keys for cars and perform more than locking doors. They can also turn on the engine as well as activate alarms and perform a variety of other functions.
The key fob uses radio signals to communicate with a receiver that is installed in the vehicle. When you hit a button on the key fob, it will send a code to the receiver, which then responds by performing the function you want. Key fobs are also a favorite among commercial building owners who can integrate them into a larger access control system. This lets them track who is allowed in or out, and they can block fobs which have been taken or lost.
Key fobs, like any electronic device, can malfunction. They may be damaged or lose their signal when they are lost in purses or pockets. While they are able to take many abuses however, they're not impervious to damage. They are made from metal and plastic.
If your key fobs aren't working, you may need to replace the battery. Make sure to use the correct battery, and consult your owner's manual to learn how to replace it correctly. Be sure to follow all other steps needed for reprogramming and calibration.
Another common cause of failed fobs is simply wear and wear and tear. They may crack or wear out if they are dropped, bumped into objects, and jostled around in pockets and purses. Sometimes, a quick and inexpensive fix is all that is needed to get your key fobs up and running.

Keyless Entry
Keyless entry allows you to unlock your car and begin it without the need to insert physical keys. It makes use of a wireless signal to connect with the car's internal system, and also allows you to control different functions within the vehicle, such as climate controls or music systems.
Modern keyless entry systems utilize rolling code technology to protect against hacking and other security breaches. However, it's crucial to keep in mind that even this technology has its weaknesses. A thief could use a technique known as "replay attack" to transmit a message that is recorded by the car's receiver. After the message is recorded, a rogue device could retransmit the message to the vehicle receiver and gain access.
Depending on the vehicle's make and model, it may be possible to program new keys yourself, or you may need to hire an automotive locksmith assist you. Certain car manufacturers have a special onboard programming process and others require an advanced programming device connected to the OBD2 port.
The most common method of programming new keys for cars is to insert the fob of the key in the ignition and engage it in a specific sequence. Once the car is in "programming mode," one or more buttons on the fob are pressed to send the digital identification code to the computer. The computer then saves the code and takes the car out of programming mode.
Some manufacturers require a special advanced programmer to program key fobs and some are expensive and difficult to use for a common person. It's best to leave the task to an auto locksmith or dealer.
To start programming a keyless entry car begin by stepping into your vehicle from the driver's side and close ALL the doors except the driver's. This will prevent the system from locking your doors while you try to program the key. After that, with the ignition key and the rest of the keys you want to program nearby, push and hold the button on the fob that you want to activate until the hazard lights flash twice.
