That will thwart the crooks with the fishing rod but it won't stop the guys who break into your house for the keys. The only thing worse than waking up in the morning to find your car has been stolen is to be woken up in the middle of the night by some crackhead with a knife demanding your keys. It happens, there were a few of these stories in the mk5 board...
That was my thinking too...
If some lunatic wants to break into a secure and alarmed house to get my car keys - any car keys, it doesn't matter - they can have them.,..and I'd rather them not come upstairs and threaten me/my family in order to get them.
Cars are insured, and can be replaced.
My keys sit in a drawer, in the kitchen...anyone that seriously breaks in with the intent on taking a car will find them...and hopefully leave us well alone.
