Question: If I were to leave my keys in my shop, does the receiver just walk around with you until you find the item, or just in the house near receiver?
Document: This product works for me and saves time. I often leave my key ring near the front door on a hook so I can find it again. Sometimes, I'm rushed or my hands are full with bags so I put my keys down elsewhere, and then it gets covered up by another item.The next time I need the keys (car keys on the ring), and usually when I am in a hurry for an appointment, I can't find my keys. I alsway keep the remote on the key ring hook, and start pushing the search button and walk around the house where I may have placed the "lost" key ring.
The flat locaters are however, a little on the big side and not quite flat enough to not add bulk to a remote or any other slim item. The range is fair, about what a car remote would be, and the volume is adequate. I have had to walk around the house a few times in order to hear one of the locaters beeping from a closet or upstairs. I bought this item more as a novelty than anything else, but it has proven to be useful, especially when I'm in a rush to leave in the morning and can't remember where I put my keys.
Have you ever wanted to call other objects you lose in the house like you call your cell phone to find it? These little receivers make it possible. They work as advertised. We're busy and distracted so we often find ourselves scrambling around the house trying to find our keys so that we can leave! This product eliminates that irritation and is well worth it.
I don't know how much time my wife and I spent looking for our keys, purse, and wallet before we purchased a key finder. It works great! No more spending up to an hour searching our house for missing keys. Now we just walk around the house pressing the find button and when we enter the room where the keys are located, we hear the beep. Now we can find our misisng items in less than 5 minutes. Thank you Key finder.
What a relief to know I no longer have to waste time looking for my keys. I tend to mindlessly leave my keys in many different places as I do work around the house. With Click'n Dig Key Finder I am able to easily retrieve my keys.
The receivers use standard CR2032 coin-cell batteries, the transmitter uses a A27 battery - the package includes a spare set of batteries.Some caveats - the antenna in the iPhone attenuates the locator signal such that a locator beacon directly adhered to the iPhone won't work. I worked around this by looping a thin wire key ring holder through the iPhone rubber protective jacket she already had ( I used a left over disposable key ring  I had from the repair shop to hold my keys after service). The important thing is to get the receiver dongle away from the body of the iPhone.
He has one receiver on his key chain, one for his work keys and one in his wallet. He was skeptical as to how it would work through walls and if it would be loud enough for him to hear, to which he found it works amazingly! This is a much safer way than continuing to make keys over and over and not know where they end up. The key finder also works very well when a smaller child is around and they hid your keys, just push a button and find the missing item with ease.
on Amazon.com. Here was the answer to my prayers. The day the package arrived, I opened it and immediately hooked it to Kitty's collar. Strangely, the cat did not seem to mind at all. Although this contraption is a good inch-and-a-half long, so long as Kitty can climb, she's happy.Now, when Kitty goes missing and ignores my "Here, Kitty" commands, I simply step outside in the fresh air, walk up the driveway around the house, and find her electronically.
It has worked OK so far. You have to make sure you always know where the main locator is and take it with you while you are searching for your lost keys or other misplaced items. You  have to keep pressing the button on the main locator while you are walking around the house, otherwise you might hear a response from the lost item, but only have a general idea of where it may be located. One time I was unable to find my wallet within 10 feet distance, because it was buried under a couple of items.
So far we have only used the two key rings and they both work well. We haven't been able to decide on how to use the two flat receivers yet. They are not quite thin enough to fit comfortable into a wallet (which is the second most misplaced item around here). The beeping is definitely loud enough without being too annoying to find what you're looking for.Missing one star because one of the batteries did not work and the distance is more around 20-30 feet so you might have to walk around with the locator to find your things.
Answer: You have to push the transmitters corresponding color button of the keys. I keep my transmitter on a hook in the kitchen until something is misplaced,  Then I walk around with it till I hear the beeps of the item(keys)  So you would have to take the transmitter to the shop to find the keys. If the keys had a red tag then you would repeat multiple time a push on  the red button until you found missing set by it 3 beep answer to the push of the red button or whatever color tag would be on the keys.  Hope this helps.
