What is a key programmer?
A key programmer is a tool used to reprogram the transponder on the key of a truck or car key or fob. This is required when a new fob or key needs to be programmed. This process is often required when a fob or a key is lost or stolen. The device essentially reprograms the digital signature of the chip inside the key to match the signature of the vehicle and enable it to start.
Certain vehicles come with electronic immobilizers that stop theft by preventing the engine from being started without the proper key. This is accomplished by having the car's security system check to make sure that the fob or key has the correct digital signature. The system will shut off in the event that it doesn't. This kind of system is effective in reducing theft of automobiles, and has been made compulsory for various models of automobile by the manufacturer.
The majority of these anti-theft systems are controlled by a module that is installed in the engine compartment instrument cluster, instrument cluster, or ignition lock. In certain instances they require keys that are programmed by a professional to work with the anti-theft system. This is usually carried out by a dealer or locksmith using computers.
While it is possible to reprogramme some keys and fobs at home, it is not recommended unless you are a highly experienced automotive locksmith key programming technician. This is because a wrongly programmed key can cause the vehicle to run, not start or be destroyed. The majority of auto makers have a very specific procedure for programming these types of keys.

This credential grants you access to an encrypted database of information about the product and immobilizer and key codes using the NASTF's Secure Data Release Model. This access permits you to program and test new keys for customers quickly and effortlessly. It also provides crucial documentation and support to assist you in your daily business operations.
How do I program the key?
A key programmer is an equipment that allows you to reprogram your car's keys. It reads the data from the microchip that is in your key, and then write new information to the chip. This allows you to use the key and ensure that it works correctly. However, the process of using a key programer is a bit complicated and requires some technical expertise to make use of. Before you attempt to program the key yourself, you must seek out a locksmith expert for advice.

Be aware that not all key programmers are compatible with your vehicle and you must confirm the compatibility of the product with your vehicle's model before purchasing.
In most cases, you will need to have your key fob reprogrammed by a dealer. This is because the key fob will have to be reprogrammed with the specific information required by your vehicle's anti-theft system. Dealers typically require the VIN number of your vehicle to perform this and they typically charge a fee for this. You can save money by giving your dealer a copy, which you are able to obtain from the DMV of most states.
For certain cars you may also be able to reprogram your own key if you have another working key that is compatible with your vehicle. This is known as master key method and it is a method to program a second key on certain vehicles. For instance, if own an GM vehicle, you can insert your working key into the ignition and switch it on until the security light goes off. Once that happens then you can remove your working key, and then insert the new one to program it.
You can also buy a specialized EEPROM key programmer, which is a more expensive, but more efficient way to program car keys. This is an advanced technology which requires that you take apart the car and read the information from the chip in the key. This type of programming is ideal for professional automotive technicians who have vast experience in electronic repair.
