Car Key Programming
It is essential to program your car key to ensure that the replacement key fobs you purchase will work with your vehicle. The key will turn off the ignition but it will not start the engine, or unlock doors without this.
You can quickly and easily program your new keys by using a locksmith who has the appropriate equipment. Find out more about this procedure and why it's important.
Self-Programming
In the lead-up to the 21st century, car key technology started to move away from simple mechanical keys to the use of a combination of electronic and physical protocols to stop theft. These new keys are equipped with a microchip, which needs to be programmed to connect to the car's electronic system. Professional locksmiths with the right equipment can reprogram your keys. A lot of vehicles, especially luxurious ones, will only allow the dealer to create new keys.
The method for doing this on your own varies from manufacturer to manufacturer. In general, you will need to place the spare key in the ignition and then manipulate it (according to the directions in your owner’s manual) until the car enters programming mode. It will only last just a few seconds before the car exits the programming mode.
When your vehicle is in programming mode, you'll need to repeat the process for each key you'd like to program. The instructions in your owner's manual should be specific to the type of key and model that you want to program, as certain models come with additional security features that need to be activated (for instance a passcode required to access certain programming modes).
Some models also require a specific code that you can only obtain through the dealer for a fee. This code helps protect you from "skimming" which occurs when a thief tries to read the data on your keys through the OBD2 ports in order to steal your car.
This is a great way to save money on a replacement key, however it is important to note that if your car key isn't properly programmed it won't allow you to unlock or start the car.

Key Programmers

It's dependent on the manufacturer, however most vehicles require that you work with a dealer or auto locksmith to have the new key programmed into the vehicle's system. This requires reprogramming the new key's transponder to match the settings of the original car.
Some vehicles allow you to do it yourself, however most require a professional dealer to use a tool that can connect to the vehicle and read the programming data from the ECU. Then, the key is changed to match the car's settings and you are able to use it as an ordinary key.
There are many types of car key programmer. Certain are designed specifically for certain models and makes while others are universal and work with a wide range of automobiles. The majority of these devices have a tiny screen and a few buttons you press to enter the programming mode. After that, you can plug the device into the OBD-II port to begin reading and programming the new key.
It takes just a few minutes for a professional to program a new key in most vehicles, though certain cars may take longer and require complicated procedures to reprogram the keys correctly. Some modern vehicles, for example need a code that needs to be accessed by the car dealer to access the immobilizer system. In these instances, you should leave the task to professionals in order to avoid damaging the system and ending up without a method to start your vehicle.

Key Fobs
Modern key fobs provide a number of convenience and security advantages. They replace or supplement traditional car keys and can be used to control more than only locking doors. They can start the engine, activate 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 press a button on the key fob, it sends an appropriate code to the receiver, which in turn responds by performing the desired function. Commercial building owners also make use of key fobs as they allow them to connect them to a larger system of access control. This allows them monitor who enters and exits, and they can prevent fobs that were taken or lost.
Like all electronic devices, key fobs can fail periodically. Because they are constantly tossed around in purses and pockets they may get damaged or lose their signal. And although they are built to be able to withstand some punishment, they're not indestructible; after all, they're nothing more than metal and plastic.
If your key fob stops functioning, it could be time to change the battery. Make sure to make use of the correct battery and refer to the owner's manual to learn how to replace it properly. Also, make sure to follow any additional steps to recalibration or reprogramming that may apply.
Wear and tear is a common cause of failing fobs. As they are continually dropped, pushed into objects, and jostled about in purses and pockets they can wear down or even cracked. A simple and cheap fix can often be all you need to make your key fobs work again.

Keyless Entry
Keyless entry lets you unlock your car and start it without needing to insert physical keys. It utilizes a wireless signal to communicate with the car's system inside, and also allows you to control different features in the car like climate control or music systems.
Modern keyless entry systems use rolling code technology to guard against hacking and other security breaches. It is important to keep in mind that even this technology is not 100% secure. A thief could use the technique known as "replay attack" to send a message that is recorded by the receiver of the car. Once the message is recorded by the receiver, a rogue device could transmit the same message to the car's receiver and gain access to the secured property.
Based on the model and make, it may be possible to program new keys yourself, or you may need to hire an automotive locksmith complete the task for you. Certain car manufacturers offer an onboard program specifically designed for them, while others require that you have an advanced programmer attached to the OBD2 connector.
The most common way to program new car keys is to place the key fob in the ignition and turning it several times in a specific sequence. This puts the car in the "programming mode," and once it is, one or more fob buttons are depressed to transmit the digital identification code to the computer in the car. The computer stores the code and takes the car from the programming mode.
Certain manufacturers require you to have a special advanced programmer to program key fobs, and some of them are expensive and difficult to use for the average person. Therefore, it is generally better to let an automotive locksmith or dealer handle the task for you.
To begin the process of programming a new keyless entry car key, get into your vehicle from the driver's side and shut all the doors EXCEPT for the driver's door. This will prevent the system from locking your doors while you attempt to program the key. Press and hold the button on the fob you want to activate when the ignition is turned on and the other keys you want to program are nearby. The danger light will flash twice.
