# Silicone Keypad for Smart Door Lock Doorbell
Produced by 橡楚（湖北）橡胶有限公司
---
The Silicone Keypad for Smart Door Lock Doorbell is a custom-molded Liquid Silicone Rubber (LSR) component designed specifically for residential and commercial smart access control systems. As a core functional and user-interaction part of integrated smart door lock and doorbell units, this keypad provides reliable tactile feedback, weather resistance, and long-term durability for daily high-frequency use.
Manufactured by 橡楚（湖北）橡胶有限公司 at our facility in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, this product is produced using food-grade, high-purity LSR raw material with precision compression molding processes. We control every production step from raw material mixing to final surface treatment to ensure consistent performance across all production batches. Unlike generic rubber keypads, our LSR keypads are engineered to meet the specific environmental and mechanical requirements of outdoor-facing smart door access systems, balancing flexibility, wear resistance, and design compatibility with standard smart lock form factors.
Core selling points of our product include: custom mold design to match unique product dimensions, low outgassing, resistance to extreme temperature and UV exposure, compliant tactile force for comfortable user input, and compatibility with both conductive coating and metal dome actuation designs.
This LSR keypad exhibits stable performance across a wide range of operating conditions. The operating temperature range is -40°C to 150°C, making it suitable for outdoor installations in both cold northern climates and hot subtropical regions. UV aging resistance (1000h exposure) results in ≤ 5% hardness change and no visible cracking or discoloration, per ISO 4892-2 testing. Water and dust ingress resistance meets IP65 requirements when properly assembled into a lock housing, preventing performance degradation from rain, dew, or household cleaning liquids.
Tactile performance is consistent over the product lifecycle: the initial actuation force per key ranges from 0.8N to 2.5N (customizable per client requirement), with less than 10% actuation force change after 1 million press cycles.
Unlike general-purpose rubber or thermoplastic elastomer keypads, our addition-cure LSR formulation resists compression set, which is the primary cause of stuck or unresponsive keys after extended use. The material retains its elasticity and tactile properties even after millions of press cycles, extending the service life of the entire smart door lock doorbell unit and reducing after-sales maintenance costs.
LSR inherently resists UV radiation, ozone, temperature cycling, and moisture exposure, unlike many organic rubber alternatives that crack, harden, or discolor after months of outdoor exposure. Our silicone keypads maintain consistent performance and appearance in all common residential outdoor environments, from coastal areas with high humidity to arid regions with intense sun exposure.
We support full custom mold development to match your unique smart lock doorbell form factor, including custom key shapes, legends, hardness, and surface finishes. Our engineering team can adapt the keypad design to fit your chosen actuation method, whether you use printed carbon contacts, pre-assembled metal domes, or standalone conductive rubber actuators. This flexibility makes our product suitable for everything from compact residential smart locks to large commercial access control doorbells.
All our LSR raw materials are non-toxic, odorless, and RoHS-compliant, meeting global safety standards for consumer electronics. The material does not release volatile organic compounds (VOCs) during use, so it will not create unpleasant odors near entryways or cause irritation for users with sensitive skin.
As a specialized LSR manufacturer based in 湖北省鄂州市鄂城区, we maintain strict process control from raw material incoming inspection to final product testing. All batches are tested for hardness, dimension accuracy, and actuation consistency before shipment, ensuring that every keypad meets the agreed specification regardless of order volume.
This Silicone Keypad is purpose-engineered for integration into smart door lock and doorbell combined systems for residential and light commercial use, including:
Its environmental resistance also makes it suitable for other outdoor access control keypad applications, including gate entry keypads, parking access control buttons, and home security system outdoor panels.
We recommend choosing hardness based on your desired tactile feel and actuation design:
We produce custom-sized keypads to match your existing lock housing design. The standard maximum dimension for a single keypad is 150mm × 80mm, which accommodates most 4–12 digit smart lock doorbell designs. For larger commercial access panels, we can produce custom-sized keypads per your drawing requirements. All key dimensions, pitch, and protrusion height are customized to match your product design.
We offer two standard material grades to match different application requirements:
橡楚（湖北）橡胶有限公司 operates a quality management system certified to ISO 9001, with standardized quality control procedures applied to every production batch of silicone keypads. Our quality control process includes:
All our products are produced in our facility at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, with full traceability for every production batch.
