What is a key-programmer?
A key programmer is a tool used to change the transponder code in the car or truck fob or key. This procedure is needed when a new key or fob needs to be programmed. This process is often required when a key or fob is lost or stolen. The device basically reprograms digital signature of the chip inside the key to match the signature of the vehicle and enable it to start.
Some vehicles are equipped with electronic immobilizers which prevent theft by preventing the engine from starting without the correct key. The system checks to determine whether the fob or key is digitally signed. The system will turn off when it isn't. This kind of system is very effective in reducing theft of automobiles, and has been made compulsory for a variety of models of cars by the manufacturer.
These systems can be controlled by a module that is installed in the vehicle’s engine, instrument panel, or ignition lock. In some instances, these modules require special keys that have been specifically created by professionals to work with the anti-theft system. This is usually done by a dealer or locksmith using computers.
It is possible to reprogram certain keys and fobs yourself but it isn't recommended until you are an experienced technician in the field. This is because the wrong programmed key could cause the vehicle to fail to run, not start or even be destroyed. The majority of auto makers have a particular procedure to program these kinds of keys.
If you want to include key programming in your offerings It is recommended that you obtain an LSID (Locksmith Service ID). This credential allows you access to an encrypted database of product information and keys and immobilizer codes via the NASTF's Secure Data Release Model. Having this access allows you to create and test new keys for customers quickly and easily. In addition, it gives you important support and documentation that will aid you in your day-today business operations.
How do I program my key?
A key programmer is a piece of equipment that will help you reprogram your car's keys. It reads data from the microchip inside your key, and add new information to the chip. This will allow you use the key, and ensure that it is functioning properly. However, the procedure of using a key programer can be a bit difficult and requires some technical knowledge to utilize. So, before you try to do this by yourself you should first talk to an expert locksmith or locksmith for guidance.
You can purchase a key programer and have it professionally programmed at a cheaper cost than what you would pay a dealership to do the job for you. Be aware that not all key programmers are compatible with your car and you should make sure to check the compatibility of the product with your model of car key cut and programed before purchasing.
Most of the time you'll need to have your key fob key programming reset by a dealer. This is because the key fob will have to be reprogrammed with specific data for your vehicle's anti-theft system. Dealers typically require the VIN number of your vehicle to do this, and they charge fees. You can save money by providing your dealer a copy which you will be able to obtain from the DMV of the majority of states.
For certain cars, you can also try to program your own key if you have a second working key that is compatible with your car. This is known as the master key method and it is applicable to certain vehicles to program an additional key. If you own an GM vehicle, for instance, insert your key into the ignition until the security light turns off. After that, you can remove the working key and insert the new one to program it.
You can also purchase an specialized EEPROM key programmer, which is a costlier but more effective method of programming car keys. This is the most advanced technology available, which requires that you take apart the car and read the data from the chip inside the key. This kind of programming is best suited to skilled automotive technicians with extensive experience in electronic repair.
