Chevy Silverado key fob lost on beach across from The Ashcroft

I was on the beach in early July across from The Ashworth Hotel. I had my keys wrapped in my t-shirt bc I'd gone into the water for a quick dip and when I came out I grabbed my t-shirt and went back down to rinse off my flip flops, bending over forgetting that my keys were wrapped up in my shirt. They must have fallen out either when I was bent over rinsing my flip flops off or walking to my truck in the parking lot. I didn't realize that they weren't in my shirt until I got to my truck. I then asked the meter reader if I could use his cellphone to call my wife so she could bring my spare key bc my phone was locked in the truck. On order to have a spare key fob made, it's going to cost me $400. Until then, I only have one key fob for my truck.
