Rental Car Keys are Horrible

Introduction
I've been having my car repaired, so I've found myself in a bunch of rental cars lately.

I hate the keys. They give you two keys with remote-control door locks tethered together with a big plastic tag.

But what good is having both keys if they are locked together? If you lock them in the car, they are both going to be locked in the car. If you lose them in the locker room at the pool, they are both going to be lost.

I comprehend that the rental place doesn't want to have the keys separated, because it could be hard to reunite them if you drove the car to Chicago or something. So they give you both of them.

Maybe they also figured out that bigger keys were harder to misplace.

I asked at the Enterprise rental car place and the response was, "if one of the keys stops working, you'll still have another key". Ok. I can't say that's ever happened, especially with radio-remote keys. The metal part of the key is already a backup of the remote, and vice versa.

I called Avis to find out what happens if you lose the keys to one of their rentals. They said I should get a locksmith, or they cans send roadside assistance. I'd pay for it, unless I'd purchased "roadside safety net". Their price to replace the rental car keys was $375.

It seems like a disservice to encumber me with this pointless extra key.
