Car Key Programming
Car key programming is a crucial step to ensure that the replacement key fob that you purchase works with your vehicle. The key will turn on the ignition, but will not start the engine or unlock doors without this.
You can easily and quickly program your new keys using locksmiths who have the right equipment. Read on to learn more about the process and the reasons why it's so important.
Self-Programming
In the years leading up to the 21st century, car keys technology started to move away from simple mechanical keys and toward the use of a combination of electronic and physical protocols to stop theft. Most of these new keys have a microchip integrated into them that must be programmed to connect the vehicle's electronic system. Professional locksmiths with the necessary equipment can reprogram your keys. Many cars, especially high-end ones, allow only the dealer to create new keys.
If you'd like to attempt this yourself, the procedure is different for each manufacturer. In general, you will need to put the spare key into the ignition and manipulate it (according to the instructions in your owner’s manual) until the car enters programming mode. You will need to move quickly, as this only lasts a few seconds before your car is out of the mode.
Once your vehicle is in programming mode, you will have to repeat the procedure for each key that you'd like to program. The instructions contained in the owner's manual must be specific to the type of key and model you are trying to program, since some models come with additional security features that have to be enabled (for instance, a passcode that is required to enter certain programming modes).
Certain models also require a code that you can only get through a dealer for a cost. This code protects against "skimming" which occurs when a thief tries to read the information on your keys through the OBD2 ports to steal your car.
This is a great way to save money on a replacement car key, but it's important to remember that if your car key isn't programmed correctly it won't be able to unlock or start the vehicle. J.C.

Key Programmers
You might wonder if it's possible to reprogram your key if you have lost them or are replacing them. It's dependent on the manufacturer, however most cars require that you collaborate with a dealer or auto locksmith to have the new key inserted into the vehicle's system. This involves reprogramming of the transponder in the new key to match the original settings of your car.
While some cars allow you to do this yourself, most require a professional or dealer to use a special 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 is compatible with the car's settings and it can be used as a regular key.
There are a variety of car key programmers, some of which work with specific makes and models of cars some are more universal and can be used on a wide variety of automobiles. Many of these devices come with an LCD display with a few buttons to enter the programming modes. After that, you can connect the device to the OBD-II port to begin reading and programming the new key.
It only takes a few minutes for a professional to program a new lock in the majority of vehicles, however some cars require longer and more complicated procedures to reprogram the keys correctly. Certain modern automobiles, for instance need a code that can only be accessible by the dealer to read the immobilizer system. In these cases it is best to leave the task to professionals in order to avoid damaging the system and resulting in a non-existent way to start the vehicle.

Key Fobs
Modern key fobs come with numerous security and convenience benefits. They can replace or supplement traditional car keys and can perform more than locking doors. They can also turn on the engine, activate alarms, and perform many other functions.
The key fob communicates with receiver in the vehicle via radio signals. When you hit a button on the key fob, it sends an encoded code to the receiver, which responds by performing the function you want. Key fobs are also a favorite among commercial building owners, who can incorporate them into the larger access control system. They can monitor who enters and exits, and block fobs which have been stolen or lost.
Key fobs, as with any other electronic device, may malfunction. As they are constantly jostled around in pockets and purses they may get damaged or lose their signal. While they can withstand some abuse however, they're not impervious to damage. In the end, they are made of plastic and metal.
If your key fobs stop working, it may be time to change the battery. Be sure to use the correct battery and refer to the owner's manual for instructions on how to replace it correctly. Also, ensure that you follow any additional steps for recalibration or reprogramming that may apply.
Simple wear and tear is a frequent cause of failing fobs. When they are constantly dropped, bumped into things and tossed around in purses and pockets, they can become worn down or even cracked. A simple and cheap fix can often be all that's needed to restore your keyfobs to working order.

Keyless Entry
Keyless entry lets you unlock your car and start it without having to insert physical keys. It uses a wireless signal to connect with the car's internal system and it can also allow you to control different functions within the vehicle 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 isn't 100% secure. Thieves could use a technique referred to as "replay attack" to send a message which is recorded by the car's receiver. Once the message is recorded an intruder device could send the same message again to the car's receiver and gain access to the secured property.
Depending on the vehicle's make and model It may be possible to program new keys on your own or you may have to hire an automotive locksmith complete the task for you. Certain car manufacturers have a special onboard programming process, while others require an advanced programming device connected to the OBD2 port.
The most common way to program new car keys is by putting the fob of the key in the ignition and engaging it multiple times in a particular order. When the car is in "programming mode," one or more buttons on the fob are pressed to transmit the digital identification code to the computer. The computer then stores this code and removes the car out of programming mode.
Certain manufacturers require that you have a special advanced programer to program key fobs. These are expensive and are difficult to use for the common person. For this reason, it's best to let a professional locksmith or dealer do the work for you.
To begin the process of programming a new keyless entry car key, get into your vehicle from the driver's side, and close all doors, excluding the driver's door. This will prevent the system from locking the doors while you are trying to program the key. Then, with the ignition key and the rest of the keys you wish to program in the vicinity, push and hold the button on the fob that you wish to activate until the hazard lights flash twice.
