Small plastic box for car keyfob?

Jan 18, 2017 39 Replies

I need a box, clip shut that can contain a cuboid 70x40x20ish mm car keybob.



Can anyone think of a style of box that small and where I could buy one?


We can a real problem with the cars being left unlocked - or rather locked, then unlocked by keys being squashed in a pocket or handbag.



I'm annoyed enough that I will 3D print one if it comes to it - but if there's a box I could fit it in, not much bigger than the fob, and still hang it off a key bunch, that would be great.



We don't even need the buttons - it's a proximity system and there's buttons on the car door handles that open it.



But if I did, I'd drill 3 x 1/2" holes in so a finger could poke the putton, but accidental presses would be unlikely.


It's not just me then!!! The other "feature" (of my Skoda) is a long press of the unlock button winds down all four windows by default, why this would be useful to anyone escapes me, winding the up with the lock button is great, but not down. Fortunately the feature can be switched off in the menu.

If you don't need the buttons then take the battery out.

The immobilizer/proximity stuff doesn't usually need the battery, only the remote lock/unlock.

Thank you! That is a good choice...

Nice thinking.

In this case I think it does use the battery as the "if the battery is dead, use the manual key and holdthe fob to the ignition button" suggests it needs power.

Might not be :o just realished, those are outside dimensions. :(

Same on the model car we have, windows down and if held further sunroof opens to tilt position.

Find it very useful on a hot day to open the windows and roof from the living room, Restaurant, Hotel window etc and let some of the heat accumulated in the car to escape before we go out to it.

It literally shows having to touch the fob to the start button.

But I can certainly try removing the battery and see what gives...

They generally don't need the battery for the immobiliser: there's an RFID chip inside the key body.

If it's like my car though, it'll flag up an irritating "Key fob battery low" alert every time you start the engine. You then have to faff about to acknowledge and hide the warning.

A more elegant solution might be to buy a key fob soft cover (see

for an example) and then slide a piece of stiff but flexible material between the cover and the buttons. A bit cut out of a plastic bottle say.

Look around for smallest toy Xmas lights packaging in the sales and you might get something in that sort of size range or as the smallest of a Russian doll style nested set of food storage containers.

Touch wood never happened to me. Maybe the handbag or pocket needs a clear out to remove all the junk that pressed the unlock button?

Winding all the windows down as you approach the car is useful on those rare hot sunny summer days when the steering wheel is too hot to touch. I generally try to park in the shade though.

It will for the unlocking - and on this car, the key is not inserted into a slot in the dash. It merely has to be "inside the car". I reckon it needs a battery to work over a 2m range.

That's one idea.

Having been all over google, the nearest thing I can find is a leather wallet for a keyfob that might prevent activation.

All the sleeves and covers are designed to be operated through (so are soft).

I realised this morning this is a perfect use of either 3D printing or (easier to design) a box made out of laser cut laminated acrylic sheets (like the RPi cases).

provide it's still there by then, of course

Thing I can think of that I have here is a foam lined strong plastic box some ICs came in. Designed to withstand being posted with no additional protection.

Is this for one of those partner swapping parties where the car keys go in a bowl? And you don't want anyone to know you drive a Dacia? ;-)

My car has a merely "inside the car" key. And an "outside the car within

1 metre" to unlock it.

However, if the battery goes: a) small key hidden inside fob, and hidden keyhole in driver's door. b) place fob (with RFID chip) in designated place in the car (bottom of the console storage box) and the car will start.
