Attention building managers and security professionals! This 25-pack of custom proximity key fobs is exactly what you need for access control systems. These are compatible with HID systems and replace 1326, 1346, and 1386 HID Prox cards and Key Fobs - they work with standard 26 bit H10301 format at 125 kHz frequency. The best part? You get same-day customization with your specific facility code and range, making setup incredibly fast and efficient. Each fob measures 30x37x2mm - compact enough to easily attach to key rings or lanyards without being bulky. The construction feels solid and durable, built to withstand daily use and the occasional drop. While the programmed number isn't printed on the fob (for security reasons), they work seamlessly with HID-compatible readers. Whether you're managing office access, apartment building security, or any facility requiring controlled entry, this 25-pack gives you plenty of keys for your team with the convenience of bulk ordering. Important note: because these are custom-programmed items, they typically can't be returned or exchanged, so double-check your facility codes before ordering. Seriously, if you need reliable, affordable access control solutions without the HID brand price tag, these compatible fobs deliver professional performance at a fraction of the cost.
