Here is a case study I have just completed. This is a smart key system failure where 2 OE keys failed to program. I hope this helps.

Personally for me this was one of your best videos yet. I haven't had to diagnose one of these systems yet but knew that I would at the minimum need something to test the keys and antenna responses. Great to see that a scope can be used to see the antenna pulses while they hunt for the key.

Spiro Each manufacture has there own way to implement these systems. But the basic idea of testing these system is the same.

Thank you for the great video Bernie! If I may ask, what key fob tester were you using, and where can I get a copy of the book that had the different pictures of key fobs in it?

After the correct fobs were supplied, did you need to program them to the vehicle? I assume so, but didn't see any mention of that.

Thanks, great video. We have had 3 Prius's in in the last few months with either AKL on one and adding a fob to the other 2 where they will start the vehicle, but none of the wireless features function. Customers did not want any further work done, but we have a number of Prius loaners, pulling one in and use the scope technique and check the system. Thanks again.

Hi Bernie! Great job explaining the diagnostics procedure! I really like the detail you presented to everyone and the strategy behind it. Not to mention the tools which compliment the diagnostic procedures. The only thing I would have liked to have seen is the Proximity Smart key tester comparison between the two passive key fobs. The before and after affect if you wish. I have the proximity…
