APOLLO 2 button Code Hopping Remote 403Mhz

APOLLO / Sherlo 2-Button Remote ? Code-Hopping 403?MHz Benefits & Advantages Secure Code-Hopping Encryption Rolling/code-hopping technology prevents replay and cloning attacks ? stronger security than fixed-code remotes for residential and commercial gates. Reliable 403?MHz Frequency Operates around 403.55 MHz, a common local band for gate/garage automation ? good compatibility with many 403 MHz receivers and kits. Two-Button Flexibility Two independent buttons let users control two devices (e.g., main gate + pedestrian gate or gate + garage) with one compact remote. Long Range & Efficient Antenna Improved antenna and RF tuning deliver dependable range in open sites and good performance in suburban installations. Common, Easy-to-Replace Battery Uses a standard 12 V A23 / GP23A cell ? inexpensive and widely available for quick swaps without special tools. Rugged, Pocket-Friendly Design Compact keyring form factor with rubber or tactile buttons ? built for everyday handling and outdoor use. LED & Low-Battery Indicator On-button LED feedback (on many models) helps with programming and indicates low battery so users replace cells before signal weakens. Cost-Effective & Widely Supported Affordable choice used across installers and local retailers ? easy to source spares and compatible receivers if you need replacements or extras. Quick notes & compatibility Make sure your receiver supports 403 MHz code-hopping remotes before purchase (matching frequency & coding scheme is required). Expected battery life is typically long under normal use but will vary by activation frequency and temperature. For very high-security sites consider multi-factor access (e.g., remotes + PIN/keypad or phone app) in addition to code-hopping transmitters. Specs vary by manufacturer batch ? confirm frequency (403.55 MHz), battery type (A23/GP23A), and code type with your supplier.
