Ignition by MagicSmith
Ignition is a key that can penetrate any borrowed object - a bill, a sugar packet, even a spectator's sleeve. Yet, when you rip the key out, there's no hole, no rip and no damage! You can pass the key and the borrowed object IMMEDIATELY for examination - there's only one key. They won't find anything because Ignition is a REAL CAR KEY that can withstand the closest inspection - even by a locksmith!
