COMMON LOCK PROBLEMS
When the Handle Moves but the Door Will Not Lock
A handle that lifts without engaging the lock, a key that turns without securing the door, or hardware that works only when the door is open gives us useful clues. We assess the handle, cylinder, mechanism, and latch engagement together. That helps distinguish a worn component from a locking system that is struggling to line up with the frame.

04
Locks that work only with the door open

REPAIR OR REPLACEMENT
Repair the Fault or Replace the Hardware That Has Failed
The right service depends on what is worn, damaged, or unavailable. An adjustment, replacement cylinder, or compatible component may address the problem. A failed mechanism can require a broader replacement. We explain what the assessment shows, the parts needed, and the available options before work begins.

KEYS AND ACCESS
Change Who Has a Key to Your French Doors

01
Compatible cylinder rekeying
02
Sticking cylinder assessment
03
Lost-key access changes
04
Replacement cylinder options
When the lock works but access needs to change, rekeying may be possible without replacing the complete system. Compatibility depends on the cylinder and existing keyway. We can also assess a cylinder that sticks or is difficult to operate, so the service addresses both access control and everyday use.
SPECIALTY HARDWARE
Identify the System Before Ordering Replacement Parts

01
Handle and cylinder details
02
Lock-edge markings
03
Standard and multipoint arrangements
04
Compatible replacement components
A Pella, Andersen, or Marvin door name alone does not identify the lock fitted to it. Share visible markings and photos of the handle, cylinder, and lock edge so we can review the actual hardware and confirm the service scope. French doors may use standard or multipoint arrangements, and replacement parts must match the installed system. We check those details before explaining the available options. For Hoppe systems, see Hoppe multipoint lock service.

Find answers about commercial hardware, home locks, french door, multipoint systems, and mobile locksmith service across the Denver metro.
Yes. ML Locksmith provides commercial locksmith services for offices, storefronts, businesses, and managed properties, including rekeying, lock changes, lock installation, lock repair, master key systems, high-security locks, door closers, and panic/exit hardware. We also help with office and business lockouts.
We diagnose, repair, and replace French door locks and multipoint locking hardware, including three-point mechanisms and Hoppe systems. We also service patio and sliding-door locks.
Repair or replacement depends on the mechanism’s condition and compatible parts. When you call, describe the symptoms and any brand markings on the hardware.
Many home locks can be rekeyed when the existing hardware is in good condition, allowing you to change which key works without replacing the entire lock. We also repair and replace residential locks and install compatible smart and keypad locks.
For electronic locks, changing access codes is separate from rekeying a keyed cylinder. Pricing depends on the hardware, work, and location; call to discuss the service and cost before work begins.
