A lot of spanish locks are hybrid, even if you had manufactures name there is no saying you would find any specific information about
that specific lock.
"TOY" locks in spain are a good example (similar to Abus/Abloy/Luma) they are widely used in spain, the association of locksmiths even has a de-coder for it, but it is still patent pending you will not find any available blue prints for it, and unless you strip it down you will not know how it operates 100%.
