What is this? Something for a car?

I too have no idea.

It looks like there's something missing off the end.

It could be a small pen, or torch, or well anything really.

I have a draw full of crap like this.

I can't throw any of it out, because I don't know what it is.

It almost looks like a friend of mines push button for a cheaper grade remote starter.

Check and see if car has remote starter on it or add batteries and give it a try.

Could even be some kind of new age garage door opener.

Hope this is helpful.

not enough question details. the car is a Toyota. But what toyota. it depends on what car it is. But I think it's only a key chain.

It's the activation switch for the ejection seat.

I don't what it is, but obviously it is not just a keychain, but I've seen one of those in tradingpost for sale, maybe you can ask them what it is.
