AUTOOL RE110 Auto Remote Key Frequency Tester/Infrared Test/Button Battery Test

AUTOOL RE110 is a compact auto remote key frequency tester for checking vehicle remote key frequency, infrared remote output, and CR2025 / CR2032 button battery voltage. It supports the main remote key frequency bands of 315MHz, 433MHz, 868MHz, and 902MHz, with a clear 1.9-inch display, Type-C power input, AAA battery power option, and a foldable rear bracket for convenient workbench use. RE110 combines RF frequency detection, infrared remote testing, and CR2025 / CR2032 button battery voltage testing in one compact tool for key programmers, locksmiths, auto repair shops, and daily remote key checks. RE110 uses RF, BAT, and IR modes. Keep the remote key or test object close to the correct testing area for a clearer and more accurate reading. RE110 can detect supported-frequency signals from multiple remote-control scenarios. Signals must be within the supported frequency range for normal detection. Confirm the supported frequency bands, button battery range, power supply, temperature range, and product size before ordering. Key features • Frequency Detection: Measures remote key frequency and displays the value so buyers can quickly identify the key signal band. • Infrared Test: Checks whether an infrared remote is transmitting, helping confirm remote function before deeper repair work. • Button Battery Test: Supports button battery testing so users can rule out a weak key battery during diagnosis. • Operating Voltage: 4 × 1.5V AAA batteries • Type-C Power Supply: 5V / 1A • Detection Frequency Bands: 315 / 433 / 868 / 902MHz
