Cypress WRT-2+D2 Key Fob with 2-Bit DES Encryption and EV2 Technology, Includes Smartcard Insert with 2K Memory

Streamline secure access and monitoring with the Cypress Ranger WRT-2+D2 key fob transmitter. Designed for access control and security teams, this key fob combines long-range RF convenience with a built-in DESFire EV2 2K smartcard insert so users can unlock gates or present a proximity credential with a single device. The WRT-2+D2 supports 433 MHz button transmission with a typical range up to 200' and 13.56 MHz smartcard presentation up to 3.5"—ideal for parking barriers, turnstiles, doors, and alarm system workflows.

Beyond range, the unit emphasizes credential protection: 2-bit DES encryption and support for MIFARE DESFire EV2 protocols help secure authentication against cloning and tampering. The compact, weather-resistant polypropylene case, two-button layout, and CR2032 battery support make it practical for daily use in harsh environments. Compatible with WRR-44 and WRR-22 long-range receivers, it integrates smoothly into existing surveillance and access control deployments.
