Car Key Programming
Car key programming is a crucial step in ensuring that the replacement key fob that you purchase will work with your car. Without this key, the key will activate the ignition cylinder, but won't start the engine, or open the doors.
It is easy and quick to program your new keys using a locksmith who has the right equipment. Read on to learn more about the procedure and why it's important.
Self-Programming
In the decades leading up to the 21st Century, car key technology evolved from mechanical keys to a mix of electronic and physical protocols to guard against theft. Most of these new keys incorporate a microchip into them that needs to be programmed in order to connect it to your vehicle's electronics system. The best method to change the programming of your car keys is by contacting an experienced locksmith who has access to the appropriate equipment. Many vehicles, especially luxurious ones, require only the dealer is allowed to make new keys.
If you want to try and do this yourself, the method is different for each manufacturer. It generally involves inserting the spare key that works into the ignition and then manipulating it (in accordance with the directions in the owner's manual) until your car is in programming mode. It only takes only a few minutes before your car leaves the programming mode.
When your car is in programming mode, you will have to repeat the procedure for each key you'd like to program. The instructions contained in your owner's manual should be specific to the type of key and model that you're trying to program, since some models come with additional security features that need to be activated (for instance, a passcode that is required to access certain programming modes).
Certain models of vehicles require an additional code that must be obtained from a dealer at a cost to you. This code helps protect you from "skimming" in the event that a thief tries to read the information on your key via the OBD2 ports to steal the car.
It's a great method to save money, however when the key isn't programmed properly, it won't work to unlock or start your car. A trusted auto repair shop such as J.C.

Key Programmers
If you've lost your car keys, or when you're replacing them, you might wonder whether it's possible to reprogram your key. It's dependent on the vehicle manufacturer, but in the majority of cases you will need to collaborate with an auto locksmith or dealer to program the new key in the vehicle. This requires reprogramming the new key's transponder so that it matches the settings of the car that was originally programmed.
While some vehicles permit this by yourself, most require a professional or dealer to use a special tool that has the ability to connect with the vehicle and read programming information from the ECU. The key is then reprogrammed so that it is compatible with the car's settings, and you can use it as a regular key.
There are numerous kinds of car key programmers, some of which use specific brands and models of vehicles and others are more universal and can be used on a variety of automobiles. Most of these tools have a tiny screen and a number of buttons that you press to enter the programming mode. After that, you connect the device to the OBD-II port to begin reading and programming the new key.
Professionals can program a brand new car key in several seconds, but certain vehicles require longer and intricate procedures to reprogram keys properly. For example, some modern vehicles require a specific code that only the dealer has access to and uses to read the immobilizer's system. In these instances it is best to leave the job to professionals to ensure that the system is not damaged and resulting in a non-existent method to start your car.

Key Fobs
Modern key fobs provide many conveniences and security advantages. fob key programming replace or supplement traditional keys for cars and 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 press the key fob, it transmits an appropriate code to the receiver, which responds by performing the desired function. Commercial building owners also utilize key fobs because they can integrate them with an overall system of access control. This allows them to track who is entering and leaving and stop fobs that were stolen or lost.
Like any other electronic device key fobs are susceptible to failure periodically. They may be damaged or lose their signal if they are placed in purses and pockets. While they can withstand some abuse, they aren't indestructible. After all, they are made of plastic and metal.
If your key fobs aren't working, you may have to replace the battery. Make sure to make use of the correct battery and refer to your owner's manual for directions on how to replace it properly. Also, ensure that you follow any additional steps to recalibration or reprogramming that may apply.

Modern keyless entry systems employ rolling code technology to protect against hacking and other security breaches. However it's important to keep in mind that even this technology isn't without its flaws. Thieves could use the technique known as "replay attack" to transmit a message that is recorded by the car's receiver. Once the message is recorded an intruder device could retransmit the same transmission to the vehicle's receiver, and gain access to the property.
Depending on the model and make of your vehicle, you might be capable of programming new keys on your own or you may have to hire an automotive locksmith to complete the task. Certain car manufacturers offer an onboard programing process and others require you to have an advanced programer connected to the OBD2 port.
The most popular method of programming new keys for cars is to place the fob of the key in the ignition and then turn it on in a certain sequence. When the car is placed 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 removes the car from programming mode.
Certain manufacturers require a special advanced programmer to program key fobs, and some of them are expensive and difficult to use by a typical person. For this reason, it is generally better to let a locksmith in the automotive industry or dealer handle the task for you.
To begin the process of programming a new keyless entry car key, get into your car on the driver's side, and close all doors, excluding the driver's door. This will stop the system from locking the doors while trying to set up the key. After that, with the key in the ignition and the other keys you wish to program nearby, push and hold the button on the fob that you want to activate until the warning lights flash twice.
