Car Key Programming
It is crucial to program your car key in order to ensure that the replacement key fobs you purchase will work with your vehicle. The key will turn on the ignition but it will not turn the engine on or unlock doors without this.
You can easily and quickly program your new keys using a locksmith who has the right equipment. Read on to learn more about the process and why it's important.
Self-Programming
In the decades leading up to the 21st century the technology for car keys evolved from mechanical keys to an amalgamation of electronic and physical protocols to prevent theft. Many of these new keys are equipped with a microchip into them that needs to be programmed to connect them to your vehicle's electronic system. Professional locksmiths equipped with the required equipment can reprogram your keys. A lot of vehicles, especially high-end ones, allow only dealers to make new keys.
The procedure for doing this on your own is different from manufacturer to manufacturer. In general, you'll have to put the spare key in the ignition and manipulate it (according to the instructions in your owner’s manual) until the car enters programming mode. It is necessary to be quick, as this only lasts only a few seconds before your car exits the mode.
Once your car is in programming mode, you'll need to repeat the process for each key that you wish to program. The owner's manual should contain instructions specific to the model and key type that you want to program. Some models have extra security features that need to be turned on.
Certain models also require a specific code that you can only obtain through the dealer at a cost. This code protects you from "skimming" which happens when a thief attempts to read the data of your key through the OBD2 port in order to start the car, and then steal it.
This is a great way to save money on a new car key, but it's important to note that if your key isn't programmed correctly, it won't unlock or start the vehicle.

If you've lost your car keys, or when you're replacing them, you may wonder if it's possible to reprogram your key.

This process involves reprogramming the transponder of the new key to match the initial settings of your car.
While some cars permit this on your own, most require a dealer or professional to use a tool that is able to connect to the vehicle and read programming data from the ECU. The key is then reprogrammed to ensure that it matches the car's specifications and it can be used as a regular key.
There are numerous kinds of car key programmers, some of which use specific brands and models of cars, while others are more universal and can be used on a wide variety of vehicles. Many of these devices come with a small display and several buttons to enter programming modes. You can then connect the device to an OBD-II connector to start reading and programm the new key.
Professionals can program a new car key in just a few minutes, however certain cars require more time and complex methods to reprogram keys correctly. For example, some modern vehicles require a special code that only the car dealer has access to and uses to access the immobilizer's system. In these cases it is best to leave the task to professionals in order to ensure that the system is not damaged and ending up without a way to start the car.

Key Fobs
Modern key fobs offer a number of convenience and security benefits. They can replace or enhance traditional car keys and can manage more than just locking doors; they can start the engine, trigger the alarm, and perform other functions.
The key fob communicates with the receiver inside the vehicle by using radio signals. When you hit a button on the key fob, it sends an appropriate code to the receiver, which in turn responds by performing the function you want. Commercial building owners also use key fobs to integrate them into an overall system of access control. They can monitor who is allowed in or out, and stop fobs that have been lost or stolen.
Key fobs, as with any other electronic device, may malfunction. Because they are constantly tossed around in pockets and purses they are prone to damage or lose their signal. While they can endure a lot of abuse, they aren't indestructible. They are made of plastic and metal.
If your key fobs stop working, it may be time to change the battery. Make sure to make use of the correct battery and refer to your owner's manual to learn how to replace it correctly. Make sure you follow all other steps needed check here for reprogramming and calibration.
Another common cause of failed fobs is wear and wear and tear. Since they are frequently dropped, bumped into things, and jostled about in purses and pockets, they can become worn down or even damaged. A simple and inexpensive fix is often all you need to make your key fobs work again.

Keyless Entry
Keyless entry allows you to unlock and start your car without having to insert a physical key. It utilizes a radio signal to connect to your car's internal system. You can also control various features, such as the climate controls or the music system.
Modern keyless entry systems employ rolling code technology to protect against security breaches. It is important to keep in mind that even this technology is not perfect. By employing a technique dubbed "replay attack" thieves can use the transmitter of the key fob to transmit a message which is recorded by the car's receiver. After the message has been recorded, a malicious device can retransmit this transmission to the vehicle receiver and gain access.
Based on the model and make of your vehicle, you might be capable of programming new keys yourself, or you may have to employ an automotive locksmith to complete the task. Some car companies have an onboard programing process, while others require you to have an advanced programming device connected to the OBD2 port.
The most common way to program new car keys is to place the fob of the key in the ignition and then turning it on repeatedly in a certain sequence. This puts the car into a "programming mode," and once it is in this mode, one or more fob buttons are pressed to transmit the digital identity code to the car's computer. The computer saves the code and then removes the car from the programming mode.
Some manufacturers require that you have a special advanced software programer to program key fobs. They are costly and difficult to use by the average person. It is best to leave the task to an auto locksmith or dealer.
To start programming the keyless entry system start by entering your car from the driver's seat and close all the doors, with the exception of the driver's. This will stop the system from locking the doors while you are trying to program the key. Push and hold the button of the fob you wish to activate when the ignition is turned on and the other keys you want to program are nearby. The warning light will flash twice.
