No, there is no single "universal" key that opens all doors everywhere, but a Master Key can open all locks within a specifically designed system, and skeleton keys can open many older warded locks.

No key is truly impossible to copy, but some are extremely difficult due to high security, special equipment, or legal restrictions, like patented, registered keys (e.g., Medeco, Abloy, Mul-T-Lock) used in master key systems, which require authorization and special blanks, or complex electronic/laser-cut car keys (transponder, VAT).
