Yale AC-KF Sync Keyfob - Sync Alarm Accessory for Disarming Alarm, Black, 200m range

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.

Brilliant replacement ,works a treat

This is a great addition to my Yale alarm system. 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.

You can't go wrong with Yale quality but the design is not the best with the raised set button

These keyfobs are not as good as the white kefobs that I had with an older Yale alarm system. On these keyfobs the part that has to be pressed to arm the full system protrudes, so if the alarm is part armed and the keyfob is in my pocket, often my movements cause the alarm to be fully armed, often without me knowing and causing false alarms. This also happens with other family members. The older white keyfobs had separate buttons that were flush with the body of the keyfob and this problem did not occur. I don't think that I would buy these again.

A bit bigger then I thought/would have liked but it does the job perfectly fine - it sets the alarm and disarm it with a single click, you can also part set it but the main aim for getting this was the fully arm and disarm when leaving the house/coming home so I don't have to open the app nor use the keypad (which I keep in the bedroom because of its inbuilt panic button). It also has a lock feature so that you don't press any buttons by mistake. Some buyers said they cannot disarm their alarm with it, only arm but I can confirm it works ok for me - fully arm, part arm, disarm. So far happy with it and it works as expected. Adding it to my smart home sync system was a 1minute job. Delivery and packaging was no issue as bought via Amazon Prime. All in all, 100% recommend despite its bigger size.

As per many other reviews, design is poor compared to previous fobs. And actually rarely works. - Button function icons are embossed and you have to look closely to determine which is which although once familiar you won't have to look - the Arm button stands proud of the others and of the fob itself meaning it gets accidentally pressed ALL THE TIME despite how carefully I try to put it in my pocket. Presumably the designers have recognised this and have included the lock switch on the side, to prevent this occurrence rather than designing out the problem in the first place. Never had this issue with the older white fob for my sadly now defunct previous alarm. - Most importanly it fails, a lot. Aside from the accidental arming mentioned above, when I actually want to arm the system it fails to do so. The main unit beeps so it's clearly registered some kind of press but does nothing, rather than beginning the exit countdown. And even more frequently, and possibly more importantly, disarming fails. Again I get a beep indicating it's registered something, and a light flashes on the fob, yet opening the door still triggers the countdown beeps leading to a mad dash for the keypad to enter the code. It could be argued this is actually the control unit, since it did register the press but ignored, it but either way it makes the fob pretty useless. I have seen other reviews stating you don't need the fob and to use the app instead but this, whilst more reliable, seems even MORE cumbersome requiring 1, get phone and unlock it, 2, start the app, 3, fingerprint to unlock the app, 4, enter password for the app (maybe every couple of days this seems to be required, even the banking apps don't require this, ever, if you use a fingerprint) 5, finally click to disarm. Perhaps a homescreen widget would make this easier.

The key fob works perfectly. The only issue I had was pairing the fob with the alarm system as the instructions supplied with the alarm system did not quite match up with the alarm system screen text when going through the pairing process.
