Multiple car keys is what allows this family to work! I'm just griping. Because I can. We have three keys for the one the college kids drive and it's fabulous -originally 2, but one was broken and then lost so we paid the $100+ to get a new second key.... then we found the lost one this summer. So either of them can use the car without having to locate the other for the key, and I have one too. You know for if I need to pick it up to take it to the repair shop :/ I'm happy to do it because they are spending their time wisely and will keep me in my old age
