Key Gauge

By Factory Brands LTD, LLC

Open iTunes to buy and download apps.


Backup your keys! Key Gauge from Factory Brands helps you determine the key number from Schlage™ and Kwikset™ keys with your iPhone 4 and iPhone 4S. Using the iPhone's high-resolution Retina Display, Key Gauge will show you actual size images of popular keys. You can dial in the key bitting and the image on your iPhone screen will change to match that of your key. The image shown can also be flipped over to show the back of the key.

After the image on the screen matches that of your key, you can record the key number, any stamping notation that it may have and any notes. The table of key numbers, key stamps and notes can be emailed out of the application as a CSV file at any time.

Use Key Gauge to record your key numbers for your home, office and those keys at the back of your junk drawer.

Keys images currently supported are:

Schlage™ - C 5 Pin, C 6 Pin, C123, E 5 Pin, E 6 Pin
Kwikset™ - #5 and #6

This app is designed for iPhone 4 and iPhone 4s screens.

What's New in Version 1.26.0

More minor bug fixes. Proper initialize of key stamp strings and notes field in both record creation and table editing.

Customer Reviews

Great app

Works great when I see a customer out and about and they need a key cut. I just copy it to my phone then cut it later. But it needs more blanks! Looking forward to update.


Not worth 1.99. The app does not work well at all. The key pictures are not the same size as in reality. And their rendition of the Kwikset. #6 is missing a pin as it is the Titan/ultramax locks and are 6 pin.

Not as good as it sounds

From the description, you'd expect this app to be better than it is. It's not that great.

It doesn't use the iPhone's camera at all. You can't take a picture of your key and work from that.

Instead, you must manually guess the key code, enter that into a dialog box, and visually compare the synthetic image on the screen against your actual key. But it's hard to compare the image on the screen against your the actual key, so it's hard to decide whether your guess is right. (This is especially true for Schlage keys, which are manufactured to fairly tight tolerances. It's very hard to distinguish between, say, codes 65483 and 65493.)

Worse, you must be careful to not touch the screen while you're doing this, because you're likely to cause the app to switch to a different image, forgetting everything in the process.
