Smart Key System Not Beeping

folks! Haven't been on in quite a while, but have problem and need your help. I had a minor collision involving the L front fender and bumper and grille a few weeks ago. All is fixed, except the beeping that used to occur when I would use the smart key system to lock or unlock the car, etc. It was working fine when I got into the car, but no longer worked after the collision. One dealership had said there is some type of part located in the fender that might be the problem, but the body shop could not find it. Then, the local dealer also could not find anything wrong; in fact, they told me it isn't supposed to beep! They tried their manual, my manual, another '05 Prius, and the Toyota Tech Line. Now, I am not crazy or on drugs and neither is my spouse; we both remember the beep system. Besides, there was a group of wires that went into a plastic piece (connector, adaptor, or something) that was on the ground after the crash, (of course, I threw it away--silly me) and I KNOW I saw more wires with another or the other half of the plastic piece still hanging from the car in the fender area. The body shop doesn't remember seeing this???!!

Can someone please help me with some information that I can take to the dealer tomorrow. I am going to another dealer further away from home, as they said they would be open all day tomorrow and will give me a loaner car and assured me that they have very good Prius techs to figure this thing out. But I want to be armed with info in case they have the same trouble. And proof that I'm not crazy!!!

Thanks!
