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.
Review: Works well but not perfect - Overall I am happy with this fob. Our keypad is by the front door so this enables me to easily set the alarm when leaving the house via the back door to walk the dog. It is also light although a touch more bulky than I anticipated, just about comfortable for going in a pocket but you certainly want it to be any bigger. As others have commented, the button design is not ideal. It isn't that easy to see the markings and the arm button is raised and fairly sensitive. In the first couple of days I managed to start arming the alarm just by sitting down with it in my pocket or when grabbing my keys from the table. You can overcome this by using the lock button which I now leave on as a matter of course but that does make the whole process slightly more fiddly. It came in the locked position so remember to unlock it before trying to pair with your hub (Yale instructions are pretty useless).
