Do you carry a spare key in your wallet?

Seems like locking your keys in your car is something that happens to everyone. If you happen to have a cell phone on you, a call to a family member or a tow-truck service wouldn't be too bad. But what happens if you don't have a cell phone on you?

Several people I know carry a spare car and/or house key in their wallet. They get a copy made at the hardware store so it is flat which can fit nicely in the wallet. Then if they accidentally lock their keys in the car or if they somehow lose their keys, they can use the backup key in their wallet.

The only problem with this is that if the wallet gets stolen, the thief not only has your wallet, but also your car and/or house key. If you have identifications in your wallet like a drivers license and car insurance id, the thief will know where you live and what you drive.
