Using a Key Programmer
Modern key fobs do more than just function as keys. They communicate with the vehicle to turn it on and open the rear hatch and more. To do this, they need to be programmed.
Car dealerships, your automobile manufacturer, and auto locksmiths can all offer key programming services. However, you can also do it yourself if you have the proper equipment.
What is a key developer?
A key programmer is a device used to recode a transponder on the fob or key of a car or truck, or any other vehicle. This procedure is needed when a new key or fob has to be programmed. It is also necessary in the event that an existing key or fob has been lost or stolen. The device reprograms the chip within the key to match the digital signature of the vehicle which allows it to begin.
Certain cars are equipped with electronic immobilizers that stop theft by preventing the engine from being started without the proper key. The system checks to see if the key or fob is digitally signed. The system will shut off when it isn't. This kind of system is efficient in reducing car theft and has been made compulsory for many models of car by the manufacturer.
Most of these anti-theft systems are controlled by a module that is installed in the engine compartment or instrument cluster or ignition lock. In certain instances the modules require specific keys that have been specifically created by a professional to work with the anti-theft system. This is typically performed by a dealership or locksmith through computers.
Although it is possible to reprogram some fobs and keys on your own, it is not recommended unless you're an skilled technician in the field of automotive. A key that is not properly programmed could cause the vehicle to not start, or not to run or even be destroyed. The majority of auto makers have a very specific procedure to program these kinds of keys.
It is recommended that if you plan to offer key programming as part of your service you acquire an LSID. This credential grants you access to an encrypted database of product information as well as keys and immobilizer codes via the NASTF's Secure Data Release Model. Having automotive key programming allows you to create and test new keys for customers quickly and effortlessly. In addition, it also offers you support and documentation that will assist you in your day-to-day business operations.
How do I program an electronic key?
Key programmer devices can be used to reprogram the keys in your car. It reads the information from the microchip inside your key, and then write new data to the chip. This will allow you to use your key and will ensure it is working properly. The process of using a programer can be a bit complicated and requires technical expertise. Therefore, before attempting to complete this task yourself it is recommended to first consult an expert or locksmith for guidance.
You can also purchase a key programmer and have it professionally programmed at a cheaper cost than what you would have to pay an auto dealer to do the work for you. However, keep in mind that not all key programmer models are compatible with your car and you must ensure the product's compatibility with the model of your car before making a purchase.
Dealers typically need to reprogramme your key fob. This is because the key fob needs to be programmed with the specific information required by your vehicle's anti-theft system. Dealers will usually need the VIN number of the car to accomplish this, and they charge an amount. You might be able to reduce the cost by providing the dealer a copy of your title, which you can obtain through the DMV in most states.
You can also change the programming of your key on some cars in the event that you already have a functioning key. This method is known as the master key method, and it can be applied to certain vehicles to program an additional key. If you have an GM car, for example put your key in the ignition until the security light turns off. When the security light is out, you can take off the working key and then insert the new one.
You can also buy a specially designed EEPROM key programmer, which is a costlier but more effective way to program the car key. This is an advanced technology which requires you to remove the car from its frame and read the data from the chip inside the key. This type of programming is best suited to skilled automotive technicians with vast experience in electronic repair.
