Door Lock – Same Look, different Durability

Mortise lock is among the most durable lock – or supposed to be. Buy a good one will last you a lifetime.

Lousy Locks (But cheap)

Out of all our locksmith services, we do come across some pretty new mortise locks that had totally broken beyond repair, without sign of abuse.

Common brands that we replace are some unknown brand (a brand that is not known by any locksmith are 95% come from China)

We do remember some that we often change/ break due to lockout, like Fuyu (China), Kasa (China), no brand (China), and Tyson (China). Average age is like 3 to 5 years.

Really Good Durable Locks (Worth every penny)

We also serviced some, really old lock that just need to top up some oil like Frascio (25 years old Italian), Yale (10 years old British), Chubb (30years old British), Kale (20 years old Turkish). 
How do you differentiate good and cheap locks? 

Ask a professional.
