What brands of locks do you install?
Tristar Locksmith works with all major residential and commercial lock brands including Schlage, Kwikset, Baldwin, Defiant, and Yale smart locks. If you have a specific brand in mind, let us know when you call and we'll confirm availability.
Can I supply my own lock and have you install it?
Yes. Many customers purchase their lock from a hardware store or online and have us install it. We charge a standard installation fee for this service and will verify the lock is properly fitted and secure before completing the job.
Do you reinforce the door frame when installing a new lock?
On request, yes. A deadbolt is only as strong as the strike plate and door frame behind it. We can install reinforced strike plates with 3-inch screws that anchor into the door stud, significantly increasing kick-in resistance for homes throughout Knoxville.
