Using a Key Programmer
Modern key fobs aren't simply keys; they can communicate with a vehicle to start it or open the rear hatch, and more. To do so, they need to be programmed to work together.
All car dealerships, auto manufacturers and auto locksmiths provide key programming. You can also do it yourself, if you have the right equipment.
What is a key programer?
A key programmer is a device used to recode the transponder in a key or fob for the vehicle, truck or other vehicle. This process is necessary when a new fob or key needs to be programmed. It is also often necessary in the event that an existing key or fob has been lost or stolen. The device basically reprograms digital signature on the chip inside the key to match that of the vehicle and allow it to begin.
Some vehicles come with electronic immobilizers that protect against theft by preventing the engine from starting without the correct key or fob. This is accomplished by having the system check to make sure that the key or fob has the right digital signature. If it doesn't, the system will shut down. This type of system has been found to be effective in reducing the incidence of theft and was made mandatory for various models of vehicles by the manufacturer.
The anti-theft system can be controlled by a device that is placed in the vehicle's engine or instrument panel, or ignition lock. In certain instances they require keys that are designed by a professional to function with the anti-theft system. This is usually performed by a dealer or locksmith who uses computers.
While it is possible to reprogramme certain keys and fobs at home, it is not recommended unless you're a highly skilled automotive technician. This is because a wrongly programed key could cause the vehicle to run, not start, or even be completely destroyed. The majority of automakers have a very precise procedure for programming these keys.
It is advised that if you intend to provide key programming as part of your service you acquire an LSID. This credential gives you access to a database of immobilizer and key codes, as well as details about the product. With this access, you are able to create and test new keys for customers quickly and effortlessly. In addition, it gives you important support and documentation that can assist you in your day-to-day business operations.
How do I program an electronic key?
A key programmer can be used to reprogram the keys of your car. It reads information from the microchip in your key, and write new information onto the chip. This will allow you to use the key and ensure that it works correctly. However the process of using a key programming device can be a bit difficult and requires some technical expertise to use. Therefore, before you attempt to do this by yourself, you should first consult an expert or locksmith for directions.
You can also purchase a key programmer and have it professionally programmed online at a cheaper cost than what you would pay a dealership to do the job for you. You should be aware that not all key programmers products will work with your specific vehicle. Before purchasing a product you must make sure that the product is compatible with your model.
Most of the time, you will require your key fob reprogrammed by a dealer. The key fob needs to be reprogrammed so that it can include the specific information for your car's anti-theft system. car key reprogramming will usually need the VIN number of your car to do this, and they will charge a fee. You can save money by providing your dealer a copy, which you'll be capable of obtaining from the DMV of the majority of states.
For some cars, you can also try to reprogram your own key if you have a second working key that works on your vehicle. This method is called the master key method and it can be applied to some vehicles in order to program an additional key. For instance, if you own an GM vehicle, simply insert your working key into the ignition and switch it on until the security light goes off. After the security light goes out, you can take off the working key and replace it with the new one.
You can also buy a specialized EEPROM key programmer which is a more expensive but more effective method of programming the car key. However, this is a much more advanced technology that requires dismantling the car and reading the information from the microchip in the key. This kind of programming is best suited to skilled automotive technicians with vast experience in electronic repair.
