What locks can locksmiths not open?

While locksmiths can open most domestic locks, there are some exceptions. Understanding these helps York homeowners know what to expect during lockouts or security upgrades.

Locks that resist non-destructive entry

Standard locks such as Yale night latches, euro cylinders, and mortice locks can usually be opened without damage by a skilled locksmith. However, high-security locks with advanced anti-pick, anti-drill, or anti-snap features may need to be drilled and replaced.

These locks are designed to prevent manipulation, so damaging entry doesn’t mean the locksmith lacks skill — it means the lock is doing its job.

Smart locks and specialist systems

Smart locks, digital keypads, and biometric systems can be more complex. Access often depends on the manufacturer and proof of ownership. Safe locks and commercial-grade systems usually require specialist engineers rather than domestic locksmiths.

If you’re unsure what type of lock you have, a local expert such as Towergate Locksmiths in York can advise you before work begins.
