Car Key Programming
It is important to program your car key in order to ensure that the key fob replacement you purchase will work with your vehicle. The key will turn the ignition, but will not start the engine or unlock doors without this.
It is easy and quick to program your new keys by using a locksmith who has the appropriate equipment. Learn more about this process and why it's important.
Self-Programming
In the decades leading up to the 21st century, car key technology evolved from mechanical keys and became an amalgamation of physical and electronic protocols to prevent theft. These new keys are equipped with a microchip which must be programmed to connect to the car's electronic system. Professional locksmiths equipped with the required equipment can reprogram your keys. Many vehicles, particularly high-end ones, allow only dealers to create new keys.
If you want to try this yourself, the procedure differs by manufacturer. It typically involves inserting the spare key that works into the ignition, and manipulating it (in accordance with the instructions in your owner's manual) until your car enters programming mode. It is necessary to be quick, as this only lasts only a few seconds before your car is out of the mode.
When your car is in programming mode, you'll need to repeat the process for each key that you wish to program. The instructions contained in the owner's manual must be specific to the key type and model that you're trying to program, as certain models have additional security features that need to be turned on (for instance a passcode required to enter certain programming modes).
Certain models of vehicles require an additional code that can only be obtained through the dealership for a fee to you. This code guards against "skimming" which occurs when a thief tries to read the information on your key via the OBD2 ports to steal your vehicle.
It's a great method to save money, but if the key isn't set up correctly, it won't be able to unlock or start your vehicle. A trusted auto repair shop such as J.C. Automotive Service, Inc. is equipped to perform computer programming as well as key reprogramming, ensuring that your vehicle is always secure. Contact us today to get started.
Key Programmers
If you've lost your car keys, or in the event that you're replacing them you might wonder whether it's possible to reprogram your key. It's dependent on the manufacturer, but most cars require that you work with a dealer or auto locksmith to have the new key inserted into the vehicle's system. This requires reprogramming the new key's transponder so that it matches the settings of the car that was originally programmed.
Some cars allow you to do it yourself, however most require a professional dealer to utilize a tool that is able to connect to the vehicle and read the programming information from the ECU. Then, the key is reprogrammed to match the car's setting and you can use it as a normal key.
There are a variety of car key programmer. Some are specific to certain makes and models, while others are universal and work with a wide variety of vehicles. Most of these tools feature a small display and several buttons to enter the programming modes. After that, you can plug the device into the OBD-II port to begin reading and programming the new key.
Professionals can program a new car key in a few minutes, however certain vehicles require longer and intricate procedures to reprogram keys correctly. For instance, some modern vehicles require a specific code that only the dealer has access to and uses to access the immobilizer's systems. In these instances you should delegate the job to professionals to avoid damaging the system and not having a method to start your vehicle.

Key Fobs
Modern-day key fobs offer many security and convenience benefits. They can be used to replace or enhance traditional car keys and be more than just a lock for doors. They can also turn on the engine or activate alarms and perform a variety of other functions.
The key fob communicates with the receiver in the vehicle using radio signals. When you press the key fob, it transmits an encoded code to the receiver, which then responds by performing the function you want. Key fobs are also very popular with commercial building owners who can integrate them into an access control system. They can monitor who enters and exits, and also prevent fobs that were taken or lost.
Like any other electronic device keys can fail at times. They can break or lose their signal if they're lost in purses or pockets. While they can take many abuses, they aren't indestructible. After all, they are made from plastic and metal.
If your key fobs are not functioning, 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. Also, be sure to follow any additional steps to reprogramming or recalibration that might apply.
Simple wear and tear is another frequent cause of failing fobs. When they are constantly being thrown around, smashed into objects, and jostled about in purses and pockets they may wear down or even cracked. Oftentimes automotive key programming is a simple and affordable fix is all that is required to get your key fobs functioning.

Keyless Entry
Keyless entry lets you unlock your car and begin it without having to insert a physical key. It uses a wireless signal to communicate with the car's system inside, and it can also allow you to control various features in the car like climate control or music systems.
Modern keyless entry systems employ rolling code technology to guard against security breaches. However, it's important to remember that even this technology has its weaknesses. Thieves could use a technique known as "replay attack" to transmit a message that is recorded by the car's receiver. Once this message is recorded by the receiver, a rogue device could retransmit the same transmission to the vehicle's receiver and gain access to the protected property.
Based on the model and make of your car, you might be able to program new keys by yourself or you may have to hire an automotive locksmith to do it. Certain car manufacturers have an onboard program specifically designed for them and others require you have an advanced programmer attached to the OBD2 connector.
The most commonly used method to program new car keys is by putting the key fob in the ignition and then turning it on repeatedly in a certain order. Once 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 saves the code and takes the car out of programming mode.
Certain manufacturers require you to have a special advanced programmer to program key fobs. These are expensive and hard to use by the average person. For this reason, it's best to let an automotive locksmith or dealer handle the task for you.
To start programming the keyless entry system begin by stepping into your vehicle from the driver's seat and close ALL the doors except the driver's. This will prevent the system from locking the doors while trying to program the key. Push and hold the button on the fob you wish to activate while the ignition is on and the other keys you want to program are nearby. The hazard light will flash twice.
