After much trepidation out of sheer embarassment, I decided to post my experience for the benefit of the forum. Leaving the gym this evening, I placed my keys in my bag and hurried to my NAH. I popped the trunk and without thinking, placed the bag (and keys) in the trunk and closed it. Instead of the car beeping at me (as it usually does to prevent accidental lock-in) it accepted the bag and locked me out. The trunk usually refuses to engage its lock if this situation occurs. This time, it failed to open and I was left stranded peering hopelessly into the cabin. I first wanted to know if this is a fluke thing or if other owners have experienced something similar.
With my new-found time waiting for my wife to save me with the spare, I figured out a solution to prevent future mishaps and thought I'd share. I took the spare valet key (not fob, just the key) and placed this in a magnetic hidden compartment carrier. I attached it to the metal framing underneath the vehicle. This time, if I do this again, I'll at least be able to gain access to the cabin (and ultimately the trunk) with the key and my wife can still hang onto the fob for additional access. Hope I save someone from future headaches.
Kind regards to everyone.
