Visit the store View our legal and compliance information Review: Handy Addition to My Yale Alarm System - Packaging: The fob arrived quickly, was very well packaged, and appeared to be a genuine Yale product right out of the box. Design: Compact and practical keyfob that fits easily on a keyring; looks and feels like a genuine Yale accessory. It features a lock button intended to prevent accidental activation or deactivation of the alarm, but I’ve found this lock button itself is quite easy to trigger accidentally, especially when the fob is in a pocket or bag. Functionality: Works well for arming and disarming the alarm, with an impressive range (easily over 100m, not tested at full 200m). Occasionally requires a double-click to lock or unlock, but otherwise reliable. If you forget to use the lock button, or if it gets pressed by mistake, it’s possible to trigger the alarm or disarm it unintentionally. Set Up: Very easy to set up-just a few clicks in the Yale Home app and it was ready to use within minutes. Straightforward instructions and quick pairing. Overall: A genuine, easy-to-use accessory that adds a lot of convenience to the Yale Sync alarm system. The lock button is a useful feature, but because it’s easy to trigger, you need to be mindful of accidental presses. Minor issue with needing to double-click sometimes, but not a dealbreaker. Highly recommended for Yale Sync users.

I would give it 5* but I find it difficult to see the right button to arm/part-arm/disable the system. I simply put a dab of paint on the disarm button. ## Frequently Bought Together - Yale AC-KF Sync Keyfob - Sync Alarm Accessory for Disarming Alarm, Black, 200m range - Yale AC-DC Sync Alarm Door/Window Contact - Sync Smart Home Alarm - 200m range - Yale IA-320 Sync Smart Home Alarm 6 piece kit.
