A key programmer is a tool used to reprogram the transponder on the car or truck key or fob. This is required when the new fob or key needs to be programmed.

Certain vehicles come with electronic immobilizers which prevent theft by stopping the engine from being started without the right key. The system checks to see if the key or fob is digitally signed. The system will shut off if it doesn't. This type of system has been proved to be effective in reducing automotive theft and was made mandatory for various models of vehicles by the manufacturer.

It is possible to reprogram certain keys and fobs by yourself but it isn't recommended until you are an experienced technician in the field. The wrongly programmed key could cause the vehicle not to start, or not to run or even to be destroyed. The majority of auto makers have a particular procedure to program these kinds of keys.

This access permits you to program and test new keys for customers quickly and effortlessly. Additionally, it provides you with important assistance and documentation to assist you in your day-to-day business operations.
