Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to get it started, open the rear hatch, and more. To do this, they need to be programmed.
Car dealerships, your car manufacturer and auto locksmiths all provide key programming services. But you can also do it yourself if you have the right tools.
What is a key-programmer?
Key programmer is a device used to recode the transponder in a car or truck key or fob. This procedure is needed when a new key or fob has to be programmed. This is usually required when a fob or key is stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle which allows it to begin.
Certain vehicles come with electronic immobilizers that protect against theft by preventing the engine from starting without the correct key or fob. This is done by having the car's system verify that the fob or key has the right digital signature. If it doesn't then the system will shut down. This kind of system has been proved 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 installed in the vehicle’s engine instrument panel, instrument panel or ignition lock. In certain instances these systems require specific keys that have been designed by experts to work with the antitheft system. This is typically done by a dealer or locksmith using a computer.
It is possible to reprogram certain keys and fobs yourself but it isn't recommended until you are an experienced automotive technician. A key that is not properly programmed could cause the vehicle not to start, fail to run or even break. Most auto manufacturers have a particular procedure for programming these kinds of keys.
If you are planning to include key programming in your service offerings, it is recommended that you acquire an LSID (Locksmith Service ID). This credential gives you access to a secure database of information about the product and key and immobilizer codes through the NASTF's Secure Data Release Model. This access permits you to program and test new keys for customers quickly and quickly. It also provides crucial documentation and support that can assist you in your daily business operations.
How do I program a key?
A key programmer can be used to reprogram the keys in your car. It reads the information from the microchip inside your key and then write new information to the chip. This will allow you use the key and ensure that it works correctly. The process of using a programer can be a bit difficult and requires technical expertise. So, before you try to do this by yourself you should first talk to an expert locksmith or locksmith for directions.
You can also purchase an online key programmer and get it professionally programmed for less than what you would pay to have a dealership do the work. Be aware that not all key programmer products will work with your car. Before you purchase it is important to determine if the item is compatible with your model.
Dealers will usually need to reprogram your key fob. This is because the key fob needs to be reprogrammed with specific data for your vehicle's anti-theft system. A dealer will typically need to have the VIN number of your car to do this, and usually charge a fee for this. You can save money by providing your dealer a copy which you will be in a position to get from the DMV of the majority of states.
For certain cars, you can also try to reprogram your key if you have a second working key that is compatible with your car. This method is known as the master key method and it can be applied to certain vehicles to program a secondary key. For instance, if you are driving a GM vehicle, insert your working key into the ignition and switch it on until the security light turns off. Once that happens then you can remove your working key, and then insert the new one to program it.
You can also purchase an specialized EEPROM key programmer which is a more expensive, but more efficient method of programming car keys. This is the most advanced technology available, which requires that you take apart the car and read the information from the chip inside the key. This type of programming is best for professional automotive technicians who have years of experience in electronic repair.
