What our mag lock repair service includes

770 Doors & Windows provides mag lock repair in NYC, Long Island. We repair magnetic locks that do not hold securely, fail to release or do not re-engage after closing. We check the magnet and armature contact, mounting, door movement, power and release controls before deciding whether adjustment or replacement is needed.

How we complete the work

  1. Observe whether the fault affects holding, release or relocking.
  2. Inspect magnet contact, mounting, door alignment and the power/control path before choosing a repair.
  3. Check the repaired entrance with its authorized entry and exit controls, then confirm closing and re-engagement.

Choosing the right scope

We identify the failed function first. Adjustment or replacement of a compatible part may be sufficient; replacement of the full system is considered when condition, support or compatibility makes repair unsuitable.

Prepare your request in NYC, Long Island

Send the magnet and armature photos, the full entrance and a description of which release controls still work.

Mounting condition, door alignment, power faults and compatibility of replacement hardware affect the estimate.

Repair before replacement

The goal is to identify the failed part before replacing equipment. Many access-control problems come from alignment, power, relay output, wiring or settings rather than the visible reader alone.

No prices listed online.Scope depends on the door, hardware and system condition.

Make a recurring magnetic lock fault easier to diagnose

Record when the door fails to hold, fails to release or behaves differently after a power interruption. Note whether the reader, intercom and exit button show the same problem or only one control is affected.

Report visible misalignment and any change in normal closing. The assessment should separate the physical opening from the release command, power and connection problems before unrelated components are replaced.

Prepare for a useful repair visit

  • Identify the exact entrance and the control used when the fault occurs.
  • Provide photos from both sides and any visible model label.
  • Coordinate access to equipment locations with the property manager.
  • Check the original symptom and ordinary door operation after the agreed work.
