remember we have a knee airbag standard. this question has been asked and answered many times. TOYOTA recommends the following:
(page 49 of the owner's manual)
"Do not attach any heavy, sharp or hard objects such as keys or accessories to the ignition key. The objects may restrict the SRS kneebag inflation or be thrust into the driver's seat area by the force of the depolying airbag, thus causing a danger."
my personal opinion is it'll probably be okay but why risk it....and in the event you get hurt by the "flying victorinox" in an accident, you won't be recovering any money from Toyota....they warned you.

 

^^ haha, well as long as none of the tools open up, I hope I'll be ok!

But I only keep the key, the tool/knife, and a little "upromise" card thingy on there.

This is what I have:

Should be fine. I thought maybe you had one of the huge ones like I have.(I dont have mine on it) But that isnt too heavy so I say itd be ok.

 

now that would do some damage in a front end collision. just keep it closed and you'll probably just get a gnarly bruise in an accident. (btw, i have no illusions that anyone will catch the warning and will continue to discuss what they hang from the key.)

My first wife carried a massive amount of dross on her keyring, and as expected, the ignition switch in her car mechanically failed on her. I have always had lightweight car key rings and in 28 cars have NEVER had an ignition switch failure.

(According to the mechs I've talked with, they almost always notice an excessively heavy keyring on cars where they have replaced intermittant or failed ignition switches.)

Just use common sense, OK?

Stupid comment.

 

yep, i don't burden the ignition with extra weight.

 

i have my car key, my house key, my pathmark thingie, a betty boop charm and a heart charm and it all weighs maybe half a lb total lol

 

Very true.. my father notices that on almost all failed ignition switches in his shop. When it fails, it will almost always stop turning with the key.. so no start. The less common failure is for the entire mechanism to fail.. so you can start the car with anything.. not so good either.
