30-Day Return Policy

Products purchased directly from lndu.com may be returned within 30 calendar days of the purchase date.

For a non-defect return, the smart lock must be in good, resalable condition and include the lock, keys, mounting hardware, manuals, promotional items, and original packaging.

Installed products may be returned only if they have been removed without damage or modification and remain complete and resalable. Products that are drilled, cut, altered, damaged, incomplete, or missing original items are not eligible for a non-defect return. This does not limit rights relating to a verified defect, shipping damage, or an incorrect item.

To start a return, contact shop@lndu.com with your order number, product model, and reason for return. Do not ship a product back without LNDU return authorization.

For non-defect returns, the customer is responsible for return shipping. For incorrect items, shipping damage, or verified product defects, LNDU will provide return instructions and, where a return is required, a prepaid shipping label.

After the returned product is received and inspected, LNDU will process an approved refund within 5 business days. Your bank or payment provider may require additional time for the credit to appear.

Approved non-defect refunds cover the product price and applicable sales tax. Original shipping, expedited shipping, and other non-product charges are non-refundable unless the return is caused by LNDU's error, shipping damage, or a verified defect. Refunds are issued to the original payment method. For complete terms, review the Refund Policy.

12-Month Limited Warranty

LNDU Smart Door Locks purchased from lndu.com include a 12-month limited warranty from the date of purchase.

This warranty covers defects in materials and workmanship under normal residential use and installation in accordance with the applicable product manual.

For a warranty claim, contact shop@lndu.com with proof of purchase, your product serial number, and photos or video of the issue when requested. LNDU may also ask for reasonable troubleshooting information.

For a verified covered defect, LNDU will determine the appropriate solution in this order: troubleshooting, setup, or firmware guidance; replacement lock or a necessary manufacturer-supplied part where appropriate; then a refund only when a replacement is not reasonably available or when required by applicable law.

This warranty does not cover normal cosmetic wear; scratches or finish changes that do not affect function; batteries; improper installation; incompatible doors; unauthorized modification or repair; misuse, abuse, impact, water exposure beyond the product rating, power damage, loss, theft, or purchases from unauthorized sellers.

A warranty claim does not automatically qualify for a refund. Once a full refund is issued, the warranty for that product ends.
