Using a Key Programmer
Modern key fobs aren't just keys. They communicate with a vehicle to start it, open the rear hatch, and so on. To do this, they must be programmed.
All car dealerships, auto manufacturers, and auto locksmiths offer key programming. But you can do it yourself if you have the proper equipment.
What is a key-programmer?
A key programmer is a device used to recode the transponder on a key or fob for the vehicle, truck or other vehicle. This process is necessary when the new fob or key needs to be programmed. This process is typically required when a key or fob is stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle, allowing it to start.
Some vehicles come with electronic immobilizer systems that prevent theft by stopping the engine from starting if it is not equipped with the correct fob or key. The system checks whether the fob or key is digitally signed. The system will turn off in the event that it doesn't. This kind of system has been proven to be effective in reducing automotive theft and is now required for various models of vehicles by the manufacturer.
These systems can be controlled by a module that is installed in the vehicle’s engine instrument panel, instrument panel or ignition lock. In some cases these systems require specific keys that have been programmed by professionals to work with the anti-theft system. This is usually done by a dealership or locksmith through a computer.
Although it is possible to reprogramme certain fobs and keys by yourself however, it is not recommended unless you are a highly experienced automotive technician. This is because a wrongly programmed key could cause the vehicle to fail to run, not start or be destroyed. The majority of auto makers have a particular procedure to program these kinds of keys.
It is recommended that if you plan to offer key programming as part of your service offerings, you obtain an LSID. This credential allows you access to an encrypted database of product information as well as keys and immobilizer codes via the NASTF's Secure Data Release Model. This allows you to swiftly and easily program and test a new keys for customers. Additionally, it offers you assistance and documentation to assist you in your day-to-day business operations.
How do I program the key?
Key programmer is an equipment that will help you change the key codes in your car. It reads the information from the microchip that is in your key, and then write new data to the chip. This will allow you to use the key, and make sure that it works correctly. However, the process of using a key programer is a bit complicated and requires some technical know-how to make use of. Before you attempt to program the key yourself, you should seek out a locksmith professional for guidance.
You can also purchase an electronic key programer and have it professionally programmed online at a cost that is lower than the cost you would pay a dealership to do the work for you. It is important to know that not all key programmer products are compatible with your vehicle. Before you purchase you must make sure that the product is compatible with your model.
Dealers typically need to reprogramme your key fob. This is because the key fob needs to be reprogrammed with the specific information required by your vehicle's anti-theft system. Dealers typically require the VIN number of your car to do this, and usually charge a fee for it. You can save money by providing your dealer a copy of the VIN, which you are able to obtain from the DMV of most states.
For some cars, you can also try to program your own key if you have a second working key that works with your vehicle. This is called a master key method and it can be used to program a different key on some vehicles. For example, if you are driving an GM vehicle, insert your working key into the ignition and switch it on until the security light goes off. Once that happens then you can remove the working key and insert the new one to program it.
You can also purchase a specialized EEPROM Key Programmer. This is more expensive, but more effective method of programming the car key. This is an advanced technology which requires that you remove the car from its frame and read the data from the chip in the key. This type of programming is best for professional automotive technicians who have vast experience in electronic repair.
