Comfort Access Key Placement

When going on a road trip I like to carry my second key with me in case of a mishap with my first key. I read the manual about leaving the second key and he it does not activate if locked with first etc... My question is where is a good place to 'hide' my second key so it s safe and does not interfere with settings and trunk closure etc.... Thanks

if you want to hide the key, I'd say simply pop the battery and switch ti upside down... should be deactivated and easy to reactivate when needed.

Could leaving the battery out for a length of time cause the key to become inactive?

I seem to recall reading in the tech doc that if a second key is in the car when the primary key locks the car, the car ignores that second key. if youi look for the pdf on comfort access, here or over on xoutpost, or google, yoiu will see this common occurnace has been designed into the system. Again, my recollection. Okay, Okay... i found it... http://www.bmwmotorsports.org/pdf/e7...t%20Access.pdf

page 17

Now, if you wanted to prevent the key from interfering, place it in a metal tin. Like an empty mint box or something.

From my personal experience, if the 2nd key is in the car (say in the middle box in between the front seats...what's that called?) and you lock the car with the 1st key, it ignores the 2nd key. Sometimes this is a real pain in the butt but I think the problem is more that hubby leaves his key in there.

Assuming your concern is losing your first key, what good is locking the second key inside the car going to do?

Good point.

I'm assuming perhaps a remote unlock via assist?

When traveling, if something happens to the first key like getting lost or broken, it is nice to have a second one. Most tow truck drivers can get you into the car...
Now if the second key gets deactivated when locked with the first, will that second key even work if the first key used to lock the door even work???
Around town I would just leave the key at home.
