Today was the first day I looked kinda like I knew what I was doing!!!
A couple came in and asked me to duplicate a key for them. I had to tell them there's no use copying it because the key has a transponder in it. I've known that since I was a kid.
Okay I left out the part where I had to get help TESTING if there's a transponder... but I still recognized that there may be one so it counts. 😌
