What our mag lock repair service includes

770 Doors & Windows provides mag lock repair in Nassau County ZIP 11797. 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 Nassau County ZIP 11797

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.

Check the complete door-release system

Describe whether the entrance fails to secure, refuses to release or works intermittently. Note whether the reader or intercom acknowledges an authorized request and whether the door closes fully. The assessment can include power, relay, release controls, lock mounting and door alignment. Keep the approved exit controls in use; do not bypass a faulty release system.

Check the whole entrance before replacing the magnet

We look at door alignment, the closer, mounting and contact between the lock and armature, along with the power supply and authorized release controls. A reader that accepts a credential does not by itself confirm that the lock is receiving the correct operating conditions.

Describe whether the door never locks, loses holding force or fails to release. Note whether the problem follows rain, a power interruption or other recent work. Keep the approved exit arrangement in use and have a technician assess faults; do not bypass the release controls.
