How to lock fob in car

Hi folks. I'm new here - just bought a 2013 Titanium hatch and still figuring it out. All in all, very happy with my new car.

I've know this was discussed before, but I've never seen a good answer. What I want to do is lock the fob inside the car and leave the emergency key in a magnetic holder somewhere on the undercarriage. That way I can canoe down the Colorado, trek the Himalayas, or go diving in Bimini without worrying my fob will be damaged, lost, or stolen.

I know I can lock it inside using the second fob, but that doesn't help me much. I could disable the fob by opening it. That works ok, but is kind of a hassle, because then when I unlock the car with the emergency key, I have to find and reassemble it really fast or the car alarm goes off. Plus, I'm afraid that the fob wasn't made to be opened and closed alot and might break.

I have tried wrapping the fob in aluminum foil, and this actually seems to work, but I'm worried that after time enough radio signal will leak out to open the doors.

Any other ideas?

I was going to suggest aluminum foil though never tried it.

Would be nice for cycling and running though.

Do they sell lead foil? Or how about a kid's metal lunchbox made in China? Surely its full of lead.

Any solid metal box will block the signal. A little mints tin.
There are all sorts of small decorative boxes which will work.
Just need one where all metal parts overlap, no holes or gaps in the metal.

why not just put the fob in a small plastic baggie for protection and hide it under the car as well.

Elizabeth, I tried an Altoids box and it didn't work. Too thin? Maybe a lunch pail is the ticket. Billp1, you're right, I could remove the battery, but I'm worried I'll damage the thing trying to reassemble it quick before the alarm starts. Vernl, the problem is that the doors won't lock if the fob is within 3 feet of the car.

The quest continues...

i had to lock keys in someone's explorer today. i put the key in the glovebox and hit the lock button. closed the door and the horn sounded and unlocked the doors. luckily, the explorer still had the push rods on the doors to manually lock the doors. i pushed them down and was golden from there.

Does the Mk3 not have the keypad on the driver's door like every other Ford?

I have the same keyless fob as you.If i place my fob under the front or back bumper, the doors dont unlock/lock.You should be able to lock the door, hide the fob and leave.The 3 ft you mention is from the sensor in the door.Try it.

I carried a spare in my suitcase that was wrapped in aluminum foil. It worked fine but only had it in there for a few hours.
I would think that the foil either works or does not and would have not considered that radio signal could leak out if it was wrapped in foil.
Maybe you could test that theory by leaving a key wrapped in foil in the car overnight.
