Using a Key Programmer

Modern key fobs go beyond simply keys; they can communicate with vehicles to start it and open the rear hatch, and more. To accomplish this, they need to be programmed to work together.

Car dealerships, your car manufacturer and auto locksmiths provide key programming services. But you can also do it yourself, if you have the right tools.

What is a key developer?

A key programmer is a tool used to recode the transponder in the key of a truck or car key or fob. This procedure is needed when a new key or fob has to be programmed. It's also common in cases where an existing fob or key has been stolen or lost. The device basically reprograms digital signature of the chip inside the key to match that of the vehicle, and allows it to begin.

Certain vehicles come with electronic immobilizers that protect against theft by stopping the engine from running without the correct key or fob. The system checks to determine if the key or fob is digitally signed. The system will shut down when it isn't. This type of system has been found to be effective in reducing automotive theft and has been made mandatory for many models of cars by the manufacturer.

These systems can be controlled by a device that is placed in the vehicle’s engine instrument panel, instrument panel, or ignition lock. In some instances, these modules need special keys that have been designed by experts to work with the anti-theft system. This is usually done by a dealership or locksmith using the use of a computer.

It is possible to reprogram certain fobs and keys yourself but it isn't recommended until you're an experienced technician in the field. The wrongly programmed key could cause the vehicle not to begin, stop running or even break. Most auto manufacturers have a particular procedure for programming these kinds of keys.

If you are planning to add key programming to your service offerings, it is recommended that you obtain an LSID (Locksmith Service ID). This credential grants you access to an encrypted database of information about the product and keys and immobilizer codes via the NASTF's Secure Data Release Model. This access permits you to program and test new keys for customers quickly and quickly. It also provides essential documentation and support that will help you with your day-to-day business operations.
