Using a Key Programmer

Modern key fobs are more than just keys programmed. They communicate with vehicles to start it or open the rear hatch, and much more. To accomplish this, they have to be programmed together.

All car dealerships, auto manufacturers and auto locksmiths provide key programming. You can do it yourself with the right equipment.

What is a key programmer?

A key programmer is used to recode a transponder on a key or fob for the vehicle truck or another vehicle. This process is required when the fob or key must be programmed. This is usually required when a key or fob is stolen or lost. The device reprograms the chip within the key to match the digital signature of the vehicle, allowing it to start.

Certain cars are equipped with electronic immobilizers that prevent theft by stopping the engine from running without the correct key. This is accomplished by having the system verify that the fob or key has the right digital signature. The system will shut off when it isn't. This kind of system has been proven to be effective in reducing automobile theft and was made mandatory for various models of vehicles by the manufacturer.

Most of these anti-theft systems are controlled by a module installed in the vehicle's engine or instrument cluster or ignition lock. In some instances the modules require special keys that have been programmed by professionals to work with the anti-theft system. This is typically done by a dealership or locksmith through computers.

While it is possible to reprogram some fobs and keys at home, it is not recommended unless you are a highly skilled technician in the field of automotive locksmith key programming. This is because a wrongly programmed key can cause the vehicle to run, not start or be destroyed. Most auto manufacturers have a specific method to program these kinds of keys.

It is advised that if you intend to provide key programming as part of your service, you obtain an LSID. This credential allows you access to an inventory of immobilizer and key codes and information about the product. This access allows you to swiftly and easily program and test new key for customers. In addition, it also 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 can be used to reprogram the keys in your car. It reads information from the microchip on the key, and write new information onto the chip. This will allow you to use the key and will ensure it is working correctly. The process of using a programer isn't easy and requires technical knowledge. Before you attempt to make this yourself, you should seek out a locksmith professional for instructions.

You can also purchase a key programmer online and have it professionally programmed for less than you would pay to have a dealer do the work for you. But, remember that not all key programmer models are compatible with your car and you must confirm the compatibility of the product with your model of car prior to purchasing.

Dealers will usually need to reprogram your key fob. This is because the key fob will need to be reprogrammed with the specific information for your car's anti-theft system. Dealers will usually need to have the VIN number for your vehicle in order to do this, and typically charge a fee to do this. You may be able to save money by giving the dealer a copy your title that you can get through the DMV in all states.

For certain cars, you can also try to reprogram your key if you already have a working key that works with your vehicle. This is known as the master key method and it can be applied to some vehicles to program the secondary key. If you have a GM car, for example, insert your key into the ignition until the security light goes out. When the security light is out, you are able to remove the working key and then insert the new one.

You can also buy an specialized EEPROM key programmer which is a more expensive but more effective method to program the car key. This is a more advanced technology, which requires that you disassemble the car key programmers and read the data from the chip in the key. This type of programming should only be carried out by professional automotive technicians with extensive experience in electronic repairs.
