Service FAQ
Is automotive locksmith work still your primary specialty?
Yes. Automotive keys, programming, all-keys-lost service, and vehicle lockouts remain our primary specialty. Residential and commercial lock services are available by request after the job is assessed.
Do you have a walk-in locksmith shop?

Can you install or repair an existing door lock?
Yes, for many common residential and commercial lock situations. Send photos of the door, lock, and damaged area so the required hardware and service can be assessed before dispatch.
