Clear Help for Lock Repair
A deadbolt that will not turn may be loaded against the strike rather than broken. A key that sticks may be worn while the cylinder is still usable. Diagnosis separates a minor alignment problem from a failing lock body.
Repair should end with repeated tests while the door is open and closed. That confirms the bolt, latch, strike, key, thumb turn, and door movement work together.
Before work starts: confirm the estimated scope, service-call terms, labor, parts or programming, and what could change the final price. The technician requests proof of ownership or authorization when access is involved.
