Using a Key Programmer
Modern key fobs are more than just function as keys. They communicate with the vehicle to get it started, open the rear hatch, and more. To accomplish this, they have to be programmed together.
All automotive dealerships, auto manufacturers, and auto locksmiths offer key programming. You can do it yourself with the right tools.
What is a key developer?
A key programmer is used to reprogram the transponder on the fob or key for the vehicle, truck or other vehicle. This is needed when a new fob or key must be programmed. It is also necessary when an existing fob or key has been stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle and allows it to start.
Certain vehicles come with electronic immobilizers which prevent theft by stopping the engine from being started without the right key. The system checks to see if the key or fob is digitally signed. The system will turn off in the event that it doesn't. This kind of system has been found to be effective in reducing the incidence of theft and is now required for many models of cars by the manufacturer.
The anti-theft system can be controlled by a module that is installed in the vehicle’s engine, instrument panel or ignition lock. In certain instances, these modules need special keys that are programmed by experts to work with the antitheft system. This is typically done by a dealer, or locksmith using computer.
Although it is possible to reprogramme certain fobs and keys on your own, it is not recommended unless you're an skilled automotive technician. A key that is not properly programmed could cause the vehicle to not start, fail to run or even be destroyed. Most auto manufacturers have a very specific procedure to program these kinds of keys.
It is recommended that if you plan to offer key programming as a part of your service, you obtain an LSID. This credential allows you access to a secure database of product information and immobilizer and key codes using the NASTF's Secure Data Release Model. This allows you to quickly and easily program and test a new key for customers. In addition, it offers you assistance and documentation to assist you in your day-to-day business operations.
How do I program an electronic key?
A key programmer is an equipment that will help you modify the keys in your car. It will read information from the microchip in your key, and write new information onto the chip. This allows you to use the key and ensure that it works correctly. The process of using a programmer isn't easy and requires technical expertise. Therefore, before attempting to accomplish this yourself, you should first consult an expert or locksmith for instructions.
You can also purchase an electronic key programer and have it professionally programmed at a cheaper cost than what you would pay a dealership to do the work for you. Be aware that not all key programming products will work with your specific vehicle. Before purchasing a product, you should check to make sure that the product is compatible with the model you have.
Dealers typically need to reprogramme your key fob. The key fob must be reprogrammed so that it can include the specific information for your car's anti-theft system. Dealers typically require the VIN number of your vehicle to accomplish this, and will charge a fee. You can save money by giving your dealer a copy of the VIN, which you are able to obtain from the DMV of the majority of states.
For certain cars you may also be able to program your own key if you already have a working key that is compatible with your vehicle. This method is known as the master key method and it can be applied to some vehicles in order to program the secondary key. If you have a GM car, for example you can insert your key into the ignition until the security light goes off. After that then you can remove your working key, and then insert the new one to program it.
You can also buy an specialized EEPROM key programmer which is a more expensive, but more efficient way to program a car key. This is the most advanced technology available, which requires that you disassemble the car and read the information from the chip in the key. This kind of programming is best for professional automotive technicians who have vast experience in electronic repair.
