Product Warranty

MZE stands behind the quality of its products and warrants them against manufacturing defects under normal use. Unless otherwise specified, all MZE products carry a 3-year limited warranty from the date of purchase.

This warranty applies only to products used in normal operating conditions and excludes failures caused by:

  • Improper installation

  • Misuse or abuse

  • Vandalism or accidents

  • Improper storage or handling

  • Force majeure (e.g., fire, flood, lightning)

  • Custom-built or special-order switches

MZE is not responsible for labor costs related to product removal or reinstallation, nor any incidental or consequential damages. Upon inspection, MZE will repair, replace, or issue credit for products deemed defective due to manufacturing issues.

Return Material Authorization (RMA)

1. Activation Devices, Locks, and Switches

All returns must be pre-approved with an RMA number. Customers must provide proof of original purchase (invoice or PO number). MZE will then issue a unique RMA number and send a confirmation by email. Returns without an RMA will be refused.

2. Access Control Panels

When purchased through an authorized MZE distributor, system panels must be returned with an RMA number issued by MZE. The RMA document must be enclosed with the return. Failure to follow this process may result in rejection of the claim.

Advance Replacement

At MZE’s discretion, a replacement product may be shipped before receiving the defective unit. The replacement will be invoiced at the standard price, and full credit will be applied upon inspection and confirmation of a valid warranty issue.

How to Request an RMA

Contact MZE Customer Service:

RMA numbers are valid for 60 days from the issue date. Items returned after this period may not be accepted or credited.
