Using a Key Programmer
Modern key fobs aren't just keys. They communicate with vehicles to start it, open the rear hatch, and so on. To do so they must be programmed to work together.
Car dealerships, your vehicle manufacturer and auto locksmiths provide key programming services. However, you can also do it yourself if you have the right equipment.
What is a key programmer?
Key programmer is a device used to change the transponder code in the car or truck key or fob. This is needed when the fob or key needs to be programmed. This process is typically required when a fob or key is lost or stolen. The device reprograms the chip in the key to match the digital signature of the vehicle and allows it to start.
Some vehicles have electronic immobilizers that protect against theft by stopping the engine from starting if it is not equipped with the correct key or fob. This is accomplished by having the car's security system verify that the key or fob has the correct digital signature. If it doesn't then the system will shut down. This type of system is effective in reducing theft of automobiles, and was made mandatory for various models of automobile by the manufacturer.
Most anti-theft systems are controlled by a module installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In some cases the modules require special keys that have been designed by experts to function with the anti-theft system. This is typically carried out by a dealer or locksmith via computers.
It is possible to reprogram certain keys and fobs by yourself, but it is not recommended until you are an experienced technician in the field. The reason is that a poorly programed key could cause the vehicle to fail to start, run or even be destroyed. Most auto manufacturers have a specific method for programming these types of keys.
It is recommended that if you plan to offer key programming as a part of your service offering you get an LSID. This credential gives you access to an inventory of immobilizer and key codes along with product information. This access lets you quickly and easily program and test a new key for customers. In addition, it gives you important assistance and documentation to help you with your day-to-day business operations.
How do I program an electronic key?
Key programmer is a piece equipment that allows you to reprogram your car's keys. It will read the information from the microchip in your key, and then write new information to the chip. This will permit you to use your key and will ensure it is working effectively. The process of using a programmer isn't easy and requires technical knowledge. Therefore, before you attempt to do this by yourself, you should first consult a professional or a locksmith for guidance.
You can also purchase an online key programmer and have it professionally programmed for a much lower price than the cost to have a dealership complete the job for you. You should be aware that not all key programming products will work with your specific vehicle. Before making a purchase, you should check to make sure that the product is compatible with your vehicle.
Dealers usually have to reprogram your key fob. The key fob has to be reprogrammed so that it can include the specific information needed for your car's anti theft system. A dealer will typically require the VIN number for your vehicle in order to do this, and will typically charge a fee for this. You may be able to save money by giving the dealer a copy of your title which is available through the DMV in all states.
For certain vehicles you can also try to reprogram your own key if you have another working key that is compatible with your car. This is referred to as master key method and can be used to program a second key for certain vehicles. For example, if you have an GM vehicle, insert your working key into the ignition and switch it on until the security light turns off. After that you can take out your working key, and then insert the new one to program it.
You can also purchase a specially designed EEPROM key programmer which is a more expensive, but more efficient method to program car key s. This is the most advanced technology available, which requires you to remove the car from its frame and read the data from the chip inside the key. This type of programming is best suited to skilled automotive technicians with years of experience in electronic repair.
