Using a Key Programmer
Modern key fobs do more than simply function as keys. They communicate with the vehicle to turn it on, open the rear hatch, and more. To accomplish this, they have to be programmed together.
All automobile dealerships, auto makers and auto locksmiths can provide key programming. You can do it yourself using the right equipment.
What is a key programmer?
A key programmer is used to recode the transponder in a key or fob for a car or truck, or any other vehicle. This procedure is needed when a new key or fob has to be programmed. It is also necessary when an existing fob or key has been lost or stolen. 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 prevent theft by preventing the engine from running without the correct key. This is done by having the system check to make sure that the key or fob has the correct digital signature. The system will shut down if it doesn't. This kind of system has been found to be effective in reducing automobile theft and was made mandatory for many models of cars by the manufacturer.
Most anti-theft systems are controlled by a module that is installed in the vehicle's engine or instrument cluster or ignition lock. In certain instances they require keys that have been specifically programmed by an expert to function with the anti-theft system. This is typically carried out by a dealer or locksmith using computers.
It is possible to reprogramme certain keys and fobs yourself, but it is not recommended until you're an experienced technician in the field. The wrongly programmed key could cause the vehicle not to start, or not to run or even to be destroyed. The majority of auto makers have a precise process to program these keys.
It is recommended that if you plan to offer key programming as a part of your service offerings you acquire an LSID. This credential gives you access to an inventory of immobilizer and key codes along with information about the product. With this access, you are able to create and test new keys for customers quickly and effortlessly. It also provides crucial documentation and support 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 reprogram your car's keys. It reads data from the microchip in the key, and add new information to the chip. This will allow you use the key, and make sure that it functions correctly. The process of using a programer can be a bit complicated and requires technical knowledge. Before you attempt to make this yourself, seek out a locksmith expert for advice.
You can also purchase an online key programmer and get it professionally programmed for a much lower price than the cost to have a dealership do the work. However, keep in mind that not all key programmer models are compatible with your car and you must ensure the compatibility of the product with your vehicle's model prior to purchasing.
Most of the time you'll require having your key fob reprogrammed by an dealer. The key fob has to be reprogrammed to include the information specific to the anti-theft system of your vehicle. Dealers will usually need the VIN number of your vehicle to accomplish this, and they charge an amount. You may be able to save money by giving the dealer a copy your title, which you can obtain through the DMV in the majority of states.
You can also reprogram your car's keys when you already have a functioning key. This is called master key method and can be used to program a different key on certain vehicles. If you own an GM car, for example you can insert your key into the ignition until the security light goes out. Once this happens then you can remove the working key and insert the new one to program it.
You can also purchase an specialized EEPROM Key Programmer. This is more expensive, but more effective method of programming the car key. This is an advanced technology which requires you to take apart the car and read the information from the chip inside the key. This kind of programming should only be carried out by professional automotive technicians with extensive experience in electronic repairs.
