To protect customer rights, after purchasing a Lockin product, please complete product warranty registration on this website and properly retain the official purchase receipt and warranty card for verification when warranty service is provided in the future.
1. Limited Product Warranty
- Products purchased through Lockin official or authorized sales channels are eligible for a 2-year limited product warranty service. The warranty period starts from the date of the official sales invoice.
- If a valid purchase receipt, warranty card, or other valid proof of purchase cannot be provided, Lockin reserves the right to determine the warranty period based on the product serial number, production date, or other relevant information.
- Warranty services are only applicable to Hong Kong and Macau. Additional charges may apply for remote or designated areas. Please refer to the "Installation Service" and "Repair Service" arrangements for details.
2. Installation and Free Warranty Eligibility
- Products purchased through Lockin official or authorized sales channels must be installed by Lockin, an authorized technician, or a designated authorized service provider to be eligible for free warranty services.
- If customers install the product themselves, or if the installation is performed by individuals, companies, or service providers not authorized by Lockin, Lockin reserves the right to refuse free warranty services.
- Damage or malfunctions caused by improper installation, installation environments that do not meet product requirements, alterations to the original door body or electrical system, and other unauthorized installations by Lockin are not covered by the free warranty.
- The installation of smart locks must comply with product specifications, instruction manuals, and on-site installation conditions. If the product fails to operate normally due to door body structure, power supply system, network environment, or other on-site factors, separate charges may apply for relevant handling.
3. On-site Repair Service for Smart Locks
- Smart locks installed by a Lockin authorized technician or authorized service provider are eligible for one year of free on-site repair service, including labor costs and designated parts costs due to product malfunctions.
- During the second year of the warranty period, if on-site inspection or repair is required, the following fees will be charged at Lockin's discretion:
- On-site service fee: HKD 650;
- Parts cost: Calculated based on actual replacement parts and repair situation;
- Remote area surcharge: Charged separately based on the actual service location.
- If the smart lock was not installed by a Lockin authorized technician or authorized service provider, even if the product is still within the 2-year warranty period, customers will be charged HKD 650 for each on-site inspection or repair request, and parts costs will be charged separately as needed.
- After the repair personnel complete the inspection, if the cause of the malfunction is found to be among the situations not covered by the warranty as listed in these terms, the customer shall bear the relevant on-site fee, inspection fee, labor fee, parts fee, and other necessary expenses.
- Customers must ensure that someone is available at the site during the scheduled appointment. If repair personnel arrive and cannot enter the site, a short waiting period will be granted at Lockin's discretion; if the waiting period is exceeded, it will be considered a temporary reschedule. Customers must make a new appointment and pay an administration fee of HKD 300.
- To change an appointment date or time, customers must submit a request at least two working days in advance. Requests made after this period will be considered a temporary reschedule, and customers must make a new appointment and pay an administration fee of HKD 300.
- If an appointment needs to be changed for reasons not attributable to Lockin, including but not limited to the customer failing to arrange for personnel to be present, inability to enter the site, or installation conditions not meeting requirements, it will also be handled as a temporary reschedule, and an administration fee of HKD 300 will be charged.
