Magnetic Spare Car Key Holder

[RSDonovan]

Hi

I recently lost my remote control car key and had a very long and expensive journey to fetch the copy. To avoid this happenin in the future I would like to get a robust magnetic key holder to attach to the underside of the car. The only one I can find that looks solid and robust enough would not fit my key (reviewers have said that car keys don't fit), and my key fob (Keyless entry, Focus 2011), seems deeper than other fobs, no doubt due to the electronic wizardry inside.

Has anyone found a reliable holder that would fit a large fob, and not fall off at the first pothole?

Thanks in advance

I wonder if it's wise to have a keyless entry keyfob stuck to the outside of the car. Would the car not "see" the key and allow the car to be opened.

Could you get a metal tin, - I'm thinking an old-fashioned tobacco tin, and attach it with a heavy duty magnet?
I take bhg's point though.

Another worry is that a magnetic key box might upset the workings of the key.
A third worry; I used to keep a spare key in a magnetic box under the car in the days when keys were just that ie, no fancy electronics. When I came to sell the car, about 5 years later, the key was very corroded. I wonder how an "electronic" key would cope with that.

My spare key is just that: a key. I keep it in my wallet.

Thanks all, think I'll take Stuey's advice and keep spare in my wallet!

My car is a Volvo with keyless entry. The remote/key has a conventional key within it which can be used to open the door if the remote battery has gone flat ie, the key part is pulled out of the remote and used in a keyhole. If I do this then I have to put the remote into a slot in the dashboard as quickly as possible to stop the alarm going off. If your system works on the same principle (Ford owned Volvo when my car was made) then carrying just a key is a waste of time because you won't be able to disarm the alarm. The only way I can see for you to get around the problem is to have a key on your person and the rest of the remote, with its batteries removed, somewhere inside the car where you can get to it quickly.
