Using a Key Programmer
Modern key fobs do more than just act as keys. program car keys communicate with the vehicle to turn it on and open the rear hatch and more. To do this, they have to be programmed together.
Car dealerships, your automobile manufacturer, and auto locksmiths can provide key programming services. You can do it yourself using the right tools.
What is a key-programmer?
A key programmer is used to recode the transponder on a key or fob for the vehicle or truck, or any another vehicle. This procedure is necessary when a new fob or key has to be programmed. This process is often required when a fob or key is stolen or lost. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and allow it to start.
Some vehicles are equipped with electronic immobilizers which prevent theft by preventing the engine from being started without the right key. This is done by having the system check to make sure that the fob or key has the right digital signature. The system will shut off in the event that it doesn't. This kind of system has been proved to be effective in reducing automotive theft and was made mandatory for many models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the engine compartment instrument cluster, instrument cluster, or ignition lock. In some cases these systems require specific keys that are programmed by experts to work with the antitheft system. This is typically carried out by a dealer or locksmith through a computer.
While it is possible to reprogram some keys and fobs by yourself but it is not advised unless you're an skilled automotive technician. The reason is that a poorly programmed key can cause the vehicle to start, run or even be destroyed. The majority of auto makers have a particular procedure for programming these kinds of keys.
It is advised that if you intend to provide key programming as part of your service offerings you get an LSID. This credential gives 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 new key for customers. In addition, it also gives you important support and documentation that will aid you in your day-today business operations.
How do I program an electronic key?
Key programmer devices can be used to modify the keys of your car. It reads data from the microchip in your key, and then write new information to the chip. This will permit you to use the key and will ensure that it functions correctly. The process of using a programer isn't easy and requires technical knowledge. Before you attempt to make this yourself, you should seek out a locksmith professional for guidance.
You can also buy an online key programmer and get it professionally programmed at a much lower price than the cost to have a dealership complete the job for you. However, keep in mind that not all key programmer models will work with your car and you must ensure the product's compatibility with the model of your car prior to purchasing.
Dealers typically need 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. A dealer will typically require the VIN number of your vehicle to perform this, and will usually charge a fee for it. You can save money by providing your dealer a copy which you are capable of obtaining from the DMV of most states.
You can also reprogramme your key on some cars in the event that you already have a working key. This method is called the master key method and it can be applied to certain vehicles to program the secondary key. If you own a GM vehicle, for instance put your key in the ignition until the security light goes out. Once the security light is out, you are able to remove the working key and insert the new one.
You can also buy an specialized EEPROM Key Programmer. This is more expensive but more efficient method of programming the car key. However this is a more advanced technology that requires removing the car and reading the data from the microchip in the key. This type of programming should only be carried out by professional automotive technicians with vast experience in electronic repairs.
