Iam looking to buy a snap ethos code reader and have noticed that some come with the keys and some without. What is the purpose of the keys??i have a cheap code reader that you just plug in to read the code, can you still use a ethos tool without the keys.

Ive got a Solus Pro, the keys just allow access to the cars systems. With later software updates you get rid of the keys altogether

Depending on the system you want to access or the manufacturer, yes. I have a Verus with about 35 personality chips, and only generally use 4!
But there are times when the others are needed for slightly unusual systems

Back in the nineties there was some legal battles over manufacturers all adopting a single acces port for diagnostics which they all agreed on the common obd port , what they didn't agree to was how they were wired so the keys are mainly to steer the can hi lo data to the correct pins in the scanner lead .
