With this Idea, you need not remember
anymore. Imagine a key fob that can tell if
you actually locked your car. When you press
the lock button, it then waits for a signal
from the car that tells it that it is locked. It
then remembers that locked/unlocked state,
and displays it onto a
small LCD which says
"LOCKED 10:44AM" or "UNLOCKED 12:32PM".
It displays the locked/unlocked state of the
car, as well as when that state was updated.

Truly marvellous and easily worth a bun. I can't believe this doesn't already exist. I want one for my house too. |
|

I suppose this will never come into being as the future of car locking lies in there being a 'card' in your pocket, and the car is simply unlocked when you are nearby or locked otherwise. Once this filters down to cheaper cars, your idea will no longer be needed. |

What a missed opportunity... |
|
| |
Had a friend looking for something like this for his garage door. Never could remember if it was left up or down. [+] |
|
| |
My mother in law could use this; "did I shut the curling iron off?" is a constant fear. |
|
| |
Super simple, way smart. There needs to be a confirmation signal from the car that tells the fob what the car actually is, not just the fob remembering which button was pressed last. |
|
| |
I want one, and I want it right now. Could have used it just this weekend. |
|
| |
Every thing is redundant with new tech.
Everything. With exception of some crazy
whacked-out things coming out of HERE. |

Father: "Jimmy did you take the car out
with Dana last night?" |
|
| |
Jimmy: "No dad I was studying." |
|
| |
Father:"You're busted kid." |

People actually lock their cars? |
|
| |
On my street, I lock the car even If i'm just
stepping in for 1/2 a minute. |
|
| |
A definite +
The number of times I have gone back outside to make sure I locked the car, because I couldn't remember... |
|
| |
This is one of those "Why didn't I think of that?" ideas. |
|
| |
<edit> Instead of the time, two LEDs: Red = locked, Green = unlocked? |
|
| |
If I had a hat, I would be removing it in your honour. |

Awesome idea. OCD'ers rejoice! [+] |
|
| |
Volvo just took this one. Score one for me. |
|
| |
Nice! [+] Maybe it can also be programmed to display what the key is for, such as "parents' house". This would help forgetful people. (I threw away 2 keys this weekend... I have no idea what locks they went with) |
|
| |
As with any status system, it wouldn't tell you the
reality of the situation just the last reference. |
|
| |
'Locked 7:45am' at 12:00pm doesn't show that your
divorced
wife/husband has taken back the car. |

OCD'ers can now simply repeatedly check that the indicated time is actually the same as the time they locked the car, then that the device is actually working (by returning to the car to verify that it really is locked) etc.
OCD will find a way - more things = more things to check. |
