Do you often forget your keys? Probably not. But for the elderly, it can be weekly or even daily affair. The increased frequency of my aged father forgetting his keys and left them dangling from the keyhole outside our house, has prompted me to seek an effective solution.
Using traditional ways such as pasting reminders were all in vain. It was a simple electronic gadget that I purchased for about S$9 that saved the day.
The alarm consists of a sender (which I’ve secured to my father’s keychain) and a receiver (that is placed in his wallet). Once the receiver is out of the sender’s range, it will start to vibrate and an alarm will go off. See how it works in the following video.
Now The Cons
Basically the alarm does not work very well at longer ranges. It works perfectly only when set at the lowest range. This means the sender and receiver cannot be apart for more than a couple of centimetres.
Additionally, the setup instructions are badly written but I’ve created this video to help you set it up easily.
