FAQs About BEST Lock Service
What is an interchangeable core?
It is a keyed core that can be removed from the lock with a control key and replaced with a differently keyed core, so access can be changed in minutes without taking the lock apart.
Can you rekey BEST cores?
Yes. We rekey BEST cores or swap in new ones and keep your key system organized.
Do you need the control key to change a BEST core?
The control key makes it quick. If it has been lost, we can still remove and replace cores and set up a new control key.
Do you repair BEST locks as well as cores?
Yes. We repair BEST cylindrical and mortise lock bodies, not just the cores.
Are you a BEST authorized dealer?
No. 911 Locksmith is an independent local locksmith. We install and service BEST locks, but we are not affiliated with or endorsed by BEST or its parent company.
