Using a Key Programmer
Modern key fobs are more than just function as keys. They communicate with the vehicle to get it started, open the rear hatch and more. To do so they must be programmed to work with each other.
All car dealerships, auto manufacturers, and auto locksmiths offer key programming. You can do it yourself using the right tools.
What is a key programmer?
Key programmer is a device used to change the transponder code in a car or truck key or fob. This is needed when a new fob or key has to be programmed. This process is typically required when a fob or a key is stolen or lost. The device basically reprograms the digital signature of the chip inside the key to match the signature of the vehicle, and allows it to start.
Certain vehicles come with electronic immobilizers that protect against theft by preventing the engine from starting without the correct fob or key. This is accomplished by having the car's system check to make sure that the key or fob has the right digital signature. If it does not then the system will shut down. This kind of system is very effective in reducing automobile theft, and was made mandatory for a variety of models of cars by the manufacturer.
Most of these anti-theft systems are controlled by a module installed in the vehicle's engine instrument cluster, instrument cluster, or ignition lock. In certain instances the modules require specific keys that have been specifically programmed by professionals to work with the anti-theft system. This is typically performed by a dealer or locksmith with computers.
Although it is possible to reprogram some keys and fobs on your own but it is not advised unless you are a highly experienced automotive technician. A key that is not properly programmed could cause the vehicle not to start, fail to run or even break. The majority of auto makers have a very specific procedure to program 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 an inventory of immobilizer and key codes and details about the product. This access allows you to quickly and easily program and test a new key for customers. In addition, it provides you with important assistance and documentation to help you with your day-to-day business operations.
How do I program the key?
A key programmer is an equipment that allows you to modify the keys in your car. It reads the data from the microchip inside your key and then write new data to the chip. This will allow you use the key and ensure that it functions correctly. However, the process of using a key programer can be somewhat complicated and requires some technical knowledge to make use of. Before you attempt to program the key yourself, you should consult a professional locksmith or professional for instructions.
You can also purchase a key programer online and have it professionally programmed at a much lower price than you would pay to have a dealer do the job for you. Be aware that not all key programmers will work with your car and you should make sure to check the compatibility of the product with your vehicle's model prior to purchasing.
Most of the time, you will require having your key fob reprogrammed by an dealer. The key fob must be reprogrammed to include the specific information for your car's anti-theft system. Dealers typically need to have the VIN number of your vehicle to perform this and they usually charge a fee for this. You may be able to save this cost by giving the dealer a copy of your title which is available through the DMV in all states.
You can also reprogram your key on some cars when you already have a working key. This is known as master key method and can be used to program a different key on some vehicles. For instance, if you own an GM vehicle, insert your working key into the ignition and turn it on until the security light goes off. After that then you can remove your working key, and then insert the new one to program it.
You can also buy an specialized EEPROM Key Programmer. This is a more costly 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 performed by trained automotive technicians who have extensive experience in electronic repairs.
