Is it true that there is a master key to all TLs? A friend of mine told me that his friend had his '02 stolen and found it later without having the ignition or door locks broken. Another friend told me that his car was broken into and they took some stuff out of it, but no damages to the keyhole. Strange thing was that he remembers that he locked the car, but it was unlocked when he got back.
