A key finder, that finds your lost keys anywhere in the home, or remote control, even your pet, could be a very handy and time saving thing to have. But how well do key finders really work?
Problems With Older Key Finder and Remote Finder Devices
Key locators and remote control finders have been around over 20 years and they have improved quite a bit. In the early days they used the 27 Mhz radio band, which is the same as CB radio. Your key finder would often go off when a passing semi truck was using their radio. Newer models that have come out in the past couple of years use 433.92 Mhz and are immune to false alarms. The other big problem with older key finders was that the battery life of the remote receivers, which you place on your keys, etc, was very short. Older IC chips used a lot of power, and since they are a radio receiver and always on, the batteries would only last about a month. This got pretty expensive, when lithium batteries used to cost over $10.00 for the thin cells. Now improved electronic circuits, which use much less power, have increased battery life of key finders to over six months for most models. In addition, the cost of lithium batteries has come down to just a couple of dollars.
After having one of these gadgets for a few months I can honestly say that I don’t know how I lived without it. I bought the Easy 2 Find key finder system for under forty dollars and it has paid for itself already since at one point I was about to have to call a locksmith to get into my Jeep Cherokee.
What is The Range Of Key Finders?
The range of most key finders like this one is around sixty feet. Most use 433 Mhz technology, which is a radio frequency that is good at penetrating solid walls, even concrete ones.
The Key To Using A Key Finder
It’s important that you place the main locator device in a place where it can be found. It would be kind of ridiculous not to be able to find your keys because you couldn’t find your key finder. I accomplished this by using sticky tape to attach it to a hall light switch, where it remains at all times.
Next it would be a little ridiculous if you were trying to find your keys and did not know which of the four (or six depending on the model) colored buttons goes to what keys. You would be chasing all over the house following beeps that may not be for the thing you are looking for. Add in a mobile cat or dog with one on their collar and you can see the kind of chaos I am speaking of. You will want to print up a small piece of paper or use a label maker to make a “key” for your key finder device.
Key finders really only work if you can find them and can know what devices go with the buttons on the transmitter.
Overall I have found that they work very well, provided that you take the steps above. Key finders really work, at least the brand that I bought, the Easy 2 Find key finder, and they will save you quite a lot of time if you are prone to misplacing things or have “squirrels” at home that move things of yours around without your knowledge.
