Easy, and it makes sense!
I like the idea, But I think I will test it first with something that weighs a little more that the keys, It by chance it drops off all I lose is rocks, If not then I will put in a set of keys, I do like the idea though.
the best way to hide a key is just tape with elec. tape to a bracket under car
Take your spare key and put it in a vice and drill a little bigger hole where the ring goes. Get a slotted screw that fits your license plate and put the spare key behind the plate. Now all you need is a dime to remove the screw and get your spare key. Now you can all steal my truck but if you do please light it on fire when you are done with it so I can get a new one.
I also have a spare key in my wallet, that works much easier.
Or just never take the keys out unless you're in town and then you take them out and put them in your pocket until you return.
Of course, I don't have to worry about anyone stealing my trucks. No body wants them.
I used to do the key on the license plate screw trick.
It works alright on some cars, some it just won't work.
I find the best way is to put only the trunk key in the magnet box.
It will fit and you won't loose the box because of weight.
Then hide an ignition/door key in the trunk.
That worked when I got robbed at gun point in March.
I know, some cars just use one big heavy key for everything.
I only have older cars and trucks.
My F1 pickup has a key in the oil bath air cleaner.
Spare key somewhere in the cab of my pickup, keypad on drivers door. One of Fords better ideas!
My '13 T doesn't use a key.
Bill I totally agree
Gilbert, it should.
