Using a Key Programmer
Modern key fobs go beyond just keys; they communicate with vehicles to start it, open the rear hatch, and more. To do this, they need to be programmed together.
Car dealerships, your car manufacturer, and auto locksmiths can all offer key programming services. However, you can also do it yourself if you have the right equipment.
What is a key programer?
A key programmer is a tool used to recode the transponder in a car or truck fob or key. This process is necessary when a new key or fob needs to be programmed. It is also often necessary in cases where an existing key or fob has been stolen or lost. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle, and allows it to begin.
Certain vehicles come with electronic immobilizers that protect against theft by stopping the engine from starting if it is not equipped with the correct fob or key. The system checks to determine whether the fob or key is digitally signed. If it doesn't then the system will shut down. This kind of system is efficient in reducing automobile theft, and was made mandatory for a variety of models of cars by the manufacturer.
The anti-theft system can be controlled by a module installed in the vehicle's engine compartment or instrument panel, or ignition lock. In some instances, these modules require special keys that have been specifically programmed by professionals to function with the anti-theft system. This is usually carried out by a dealer or locksmith using a computer.
It is possible to reprogramme certain fobs and keys yourself but it isn't recommended until you are an experienced automotive technician. A wrongly programmed key can cause the vehicle to not start, or not to run or even break. The majority of auto makers have a specific method to program these kinds of keys.
It is advised that if you intend to offer key programming as a part of your service offering, you obtain an LSID. This credential gives you access to a database of immobilizer and key codes and details about the product. With this access, you are able to create and test new keys for customers quickly and easily. In addition, it also offers you support and documentation that can assist you in your day-to-day business operations.
How do I program the key?
Key programmer devices can be used to reprogram the keys of your car. It will read 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 functions effectively. However, the process of using a key programer can be somewhat complicated and requires some technical expertise to use. Before you attempt to program the key yourself, you must seek the advice of a professional locksmith professional for guidance.
You can also buy an online key programmer and have it professionally programmed at a much lower price than you would pay to have a dealer do the work. Be aware that not all key programmers will be compatible with your vehicle. You must confirm the compatibility of the product with your vehicle's model prior to purchasing.
Dealers usually have to reprogram your key fob. This is because the key fob will have to be reprogrammed with the specific data for your vehicle's anti-theft system. Dealers typically require the VIN number for your car to do this, and typically charge a fee for this. You can save money by providing your dealer a copy of the VIN, which you will be in a position to get from the DMV of most states.
You can also change the programming of your car's keys if you already have a working key. This method is called the master key method, and it is applicable to certain vehicles in order to program the secondary key. For instance, if you are driving a GM vehicle, simply insert your working key into the ignition and switch it on until the security light goes off. Once the security light goes out, you can remove the working key and replace it with the new one.
You can also purchase a specialized EEPROM key programmer that is more expensive, but more efficient method of programming a car key. This is the most advanced technology available, which requires you to disassemble the car and read the data from the chip inside the key. This kind of programming is best suited to professionals in the field of automotive mechanics who have years of experience in electronic repair.
