Using a Key Programmer
Modern key fobs go beyond just keys; they communicate with a vehicle to start it or open the rear hatch, and more. To accomplish this, they need to be programmed to work in conjunction.
All car dealerships, auto manufacturers and auto locksmiths can provide key programming. You can do it yourself if you have the right tools.
What is a key programmer?
A key programmer is a device used to recode a transponder on the fob or key of an automobile truck or other vehicle. This is required when a new key or fob needs to be programmed. It is also often necessary in cases where an existing fob or key is stolen or lost. The device reprograms the chip in the key to match the digital signature of the vehicle and allows it to start.
Certain vehicles come with electronic immobilizers that stop theft by stopping the engine from being started without the correct key. The system checks if the key or fob is digitally signed. If it doesn't then the system will shut down. This kind of system has been proven to be effective in reducing automobile theft and has been made mandatory for a variety of models of cars by the manufacturer.
Most anti-theft systems are controlled by a module that is installed in the engine compartment or instrument cluster or ignition lock. In certain instances they require keys that have been specifically created by an expert to function with the anti-theft system. This is usually done by a dealership or locksmith using a computer.
While it is possible to reprogram some keys and fobs at home but it is not advised unless you're a highly experienced automotive technician. A key that is not properly programmed could cause the vehicle to not start, fail to run or even break. Most auto manufacturers have a very specific procedure to program these kinds of keys.
If you want to include key programming into your offerings it is recommended you acquire an LSID (Locksmith Service ID). This credential gives you access to an inventory of key and immobilizer codes, as well as information about the product. This access lets you quickly and easily program and test new key for customers. In addition, it also provides you with important support and documentation that can help you with your day-to-day business operations.
How do I program an electronic key?
A key programmer is an equipment that allows you to reprogram your car's keys. It reads information from the microchip on your key, and add new information to the chip. This will allow you use the key, and ensure that it functions properly. However, the process of using a key programmer can be somewhat complicated and requires some technical know-how to make use of. Therefore, before attempting to complete this task yourself it is recommended to first consult a professional or a locksmith for instructions.
You can purchase an electronic key programer and have it professionally programmed online at a lower cost than what you would have to pay an auto dealer to do the work for you. However, keep in mind that not all key programmers will work with your vehicle and you should make sure to check the compatibility of the product with your model of car prior to purchasing.
Most of the time, you will need to have your key fob reset by a dealer. The key fob must be reprogrammed in order to include the information specific to the anti-theft system of your vehicle. Dealers typically require the VIN number of your vehicle to accomplish this, and will charge fees. You can save money by providing your dealer a copy of the VIN, which you'll be capable of obtaining from the DMV of all states.
You can also reprogram your car's key if you already have a functioning key. This is called master key method, and can be used to program a second key for certain vehicles. For instance, if you are driving an GM vehicle, simply insert your working key into the ignition and switch it on until the security light turns off. After that then programming car key can remove your working key and then insert the new one to program it.
You can also purchase an specialized EEPROM key programmer that is more expensive but more effective method of programming the car key. However it is a more advanced technology that requires removing the car and reading the information from the microchip within the key. This type of programming should only be done by trained automotive technicians who have years of experience in electronic repairs.
