Yale AC-KF Sync Keyfob - Sync Alarm Accessory for Disarming Alarm, Black, 200m range [Energy Class A+]

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.

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

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).

Purchased 3 of these as loved the fact they could be used as panic buttons as well as arming/disarming the alarm but I was very disappointed when they arrived.Firstly the batteries were dead so I had to go out and purchase new ones before I could even start using them. Secondly, the instructions were poor, I did not know how to activate the panic button feature (press the unlock and part lock button simultaneously). In all fairness Yale support were great and pointed me in the right direction regarding this feature.The device is all one colour (black). It was difficult for me to see which button to use to unlock it so I had to put a blob of white nail varnish on that side so I could easily distinguish it from the part arm. There is a slider switch to turn the device on and off. Again, it is completely black. It would have been useful for the inside of the button to be another colour i.e. white so you could easily see that the button was switched to the 'on' position and you don't accidentally leave it on and drain the battery (I have done this twice already!).I like that I can arm/disarm from up to 200 meters (tried it from 100 meters and it works) as I can't always connect to my home wifi from outside of my house to turn the alarm off via the app on my phone which is a pain but this device solves that. Just a shame that it is all one colour and the icons aren't prominent.I also purchased 2 panic buttons to put around the house and use velcro to move them to different places. I love these and will review them separately.

Good

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.

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.

Item works as needed even if WiFi disconnects from alarm system as mine did while on holiday . So bought so could stop alarm going off on my return again.
