EEPROM programming is another method that can be used to program new car keys. It is more complex and requires a deep understanding of electronic systems. This is why it's best left to a professional who has years of experience working with these kinds of systems.
Locksmiths can program a key quickly by using onboard programming. It takes as little as one minute if everything is completed correctly. If the key isn't in good working order or the procedure isn't followed exactly, the process could take up to half an hour.
There are a variety of key programmer scanners on the market that work with various vehicle models and makes.
