Good to know
High-security locks add resistance to picking, bumping and drilling, and their keys are restricted, so a shop cannot copy them without your authorization. They are most valuable when key control is the concern, for example a landlord or a business. Because most forced entries attack the frame, we always check that the door and strike are up to the job.
When this is not the right fix
A weak door or frame will undermine any lock. We may recommend repairs first.
Frequently Asked Questions
What makes a lock high-security?
A more complex cylinder that resists picking and bumping, hardened parts that resist drilling, and a restricted key.
Will a high-security lock stop a break-in?
It protects the lock. Most forced entries attack the door frame, so we also check the strike and frame.
Can I still get spare keys?
Yes, through us with proof of ownership. That is the point of a restricted key.
