SS/SE Problem!!

A buddy and I were taking off from San Diego to southern Utah for a Prius ride and photo adventure in the stunning national parks/monuments in that area. Since we'd be tent camping and moving a lot I decided it would be prudent to give him a fob to carry in case I lost mine or it went "belly up". I gave him one and kept the other one in my pocket when I picked him up. During the day, whenever we stopped for whatever it seemed like the se/ss system was kind of erratic and I became kind of concerned. We were going to some pretty remote parts of the country and a long way from any dealership help.... Late in the afternoon we were coming out of a restaurant and I got to the car before he did and the car wouldn't unlock for me. I became upset until he walked up, then magically, the car opened up. We got in and drove away, me still worried about the erratic operation. I finally decided the fob battery must be the problem so I pull it out of my pocket and take a look. Turns out that I had the remote from my Tundra............. What a knucklehead!! All worked out beautifully on the rest of my trip, once I had "his" fob in my pocket............

The bottom line was that I had a "non-fob" in my pocket most of the first day, a "regular remote" for my Tundra. I wasn't catching on that it didn't work as a real Prius fob, the car only noticed when my buddy was around. I was just wondering if other Prius owners have found that malfunctions turn out to be synapse lapses of the driver. As I said, the joke was on me............ go in peace.
