Toyota Sera reproduction "optional" key blank

An approximation of the optional key that could be bought when ordering a new Toyota Sera.

These are uncut and need to be cut by a locksmith.

These are made from a softer material to the original keys, so if your locks are still, consider cleaning them.   The lock itself can be cleaned with a solvent and then lubricated with either a graphite or teflon based lock lubricant (not oil or WD40).     The rods which operate the locks also may require the old grease which may have hardened with age cleaning off and re-greasing.
