Square-keyed access points have been used in public spaces for decades as a prevention method for various resources. The most well-known is for outdoor water taps, but these recessed square locks are also used in public transit, industrial equipment cabinets, and for radiator valves. The humble sillcock key is all you need to access them. Although they have one main purpose, there are many brands and types of sillcock keys on the market.

This is where we come in. We’ve researched the best sillcock keys, tested them, and now the results are in: the overall best, an upgrade option, and a utility option. If you need to get water from a sillcock spigot, one of our suggestions is the tool for the job.

The Best Sillcock Key

4-Way Sillcock Water Key

Inexpensive, Versatile, and Durable

Turn on most commercial water faucets with a 4-way square key you can consistently rely on.

$9* at Amazon

*Price at time of publishing; check for price changes or sales.

A simple key turned out to be the best, with machined steel construction that holds up to plenty of torque. The squares are labeled so you don’t have to continuously guess and check fit.

While we swapped out the included keychain (and you should too), it is nice that it comes with an attachment point so it’s not floating freely in your kits.

Here is what you get with this steel key:

• 1/4″ square (6mm)
• 9/32″ square (7mm)
• 5/16″ square (8mm)
• 11/32″ square (9mm)
• 5.3 ounces

This simple and dependable tool gets it done every time- so it’s easy to see why the Hautmec 4-Way Sillcock Water Key is the best.

Upgrade Sillcock Key

Knipex Twin Key

Universal, German Made, and High Quality

This smart and quality manufactured key holds together with magnets and offers a whole suite of versatility.

Knipex, best known for its industrial tools and handheld cutters, puts out the highest quality and most versatile utility key available. Using the tool steel they are known for, it blows all other sillcock keys out of the water when it comes to quality.

The magnetic nesting of two separate keys is a nice German-engineered touch since it reduces the profile but doesn’t have the keys get in the way like imitation 8-way keys do. German-made does come at a German price, however, so this upgrade isn’t for everyone.

Here is how the key measures up:

• Square: 5|6mm, 7|8mm, 9|10mm, 11mm
• Triangle: 7|8mm, 9|10mm, 11|12mm
• Two-way key bit: 3-5mm
• Half-moon: 6mm
• Step-square: 6-9mm
• 6.2 ounces

If you need a quality tool for frequent use, the Knipex Twin Key is what you’re looking for.

Best Utilities Key

Willbond Utilities Key

Lightweight, Versatile, and Reliable

Grab some extra utility for triangle and keyed opening by dropping the lesser-used sillcock squares.

$5* at Amazon

*Price at time of publishing; check for price changes or sales.

A utility key may be your best option if you simply want to access most utilities rather than all of them. It is lighter weight than our other picks, as it trims out all of the lesser-used tools and only includes the high-use sillcocks, a cabinet key, and a triangle key.

It’s not going to break any records in the durability department and you may encounter a few spigots it won’t unlock, but it will add less weight to your survival kit.

Here are the full specs:

• 1/4″ (6mm) & 5/16″ (8mm) square
• 8mm triangle
• 6mm cabinet key
• 1.9 ounces

If you are looking for a reliable utility key with a lower weight than a full sillcock set, you’ll want to pick up the Willbond 4-Way Utilities Key.

The Tools We Compared

Our research narrowed the field down to a few brands and types of tools that we compared: Willbond, Knipex, Husky, Hautmec, Cobra, Grainger, and more.

You can see our full list of review criteria below in the What to Look For section, with an explanation for each.

We considered a wide range of tools but focused on portable and lighter-weight key tools. We did not go too far with meter wrenches or other larger tools since we were comparing these for mobile kits.

We’re always looking for new and better gear, so if you have a sillcock key you love, let us know in the comments. We review most of our tested gear annually so we can try to get it in the next roundup round and see if it will beat out our top picks.

What to Look For

The best sillcock keys have a few features to look for:

1. Value
2. Durability
3. Manufacturing Quality
4. Size & Weight
5. Versatility

When you get the right blend of these, you can find a water key that will access most spigots. Below, we break down what each of these features means for the sillcock keys that truly set themselves apart.

Value: Cost vs. Benefit

The amount of money you spend on something as simple as a tool shouldn’t blow out your entire budget. Unless your budget is really strapped, they shouldn’t set you back much. There is a wide range of prices associated with quality (like most tools), so you can pick based on how much you plan to use it.

You never want to spend too much money on one tool when it comes to survival kits. It’s better to diversify your spending to make sure you are covered for a wide range of scenarios.

Durability

When you are torquing your key on a stubborn faucet, the last thing you need is for it to shatter on you. Whether it weakens over time, can’t stand abuse, or is shipped to your door with manufacturing defects- you don’t want to deal with durability concerns.

Manufacturing Quality

Manufacturing quality can influence not just durability, but also how effective your tool is by the precision of the fit.

If your tool isn’t a precise fit, you could even strip the faucet- which would be far from ideal. One of the reasons we suggested a sillcock key to begin with was due to a bad experience trying to turn a sillcock with a multitool plier.

Get the right tool for the job, and make sure that the right tool is a good tool for what it’s advertised for.

Size & Weight

The weight of sillcock keys can be a major drawback to including them in carried kits. Many people opt to keep them in their trucks or larger kits since they can add close to half a pound of weight in some cases.

Luckily, their profile is still small, so it’s not quite the same as toting a crowbar or other long tool around.

You’ll need to look at your situation and kits specifically to determine your needs and how much size and weight you can accommodate.

Versatility

The versatility of a sillcock key is typically a function of how many tools you have on the key itself. We reviewed a few of the single-size square keys, and they just didn’t cover the bases when it came to versatility.

The best sillcock key will access at least most of the public utility keyed resources in your area (if not all of them). Additionally, you could use a sillcock key as a hammer or other tool in a pinch, but hopefully, you have better tools in your kit for anything outside of a keyed utility.

How to Use a Sillcock Key

The main use of a sillcock key is to access a faucet in public. These public faucets don’t have a traditional handle on top but instead have square-keyed openings that you use a sillcock key to turn.

Some of them don’t always have running water, and many of them can be stubborn from not much use or getting painted over. Having them keyed is meant to prevent public access, but as you’ve already seen- the keys are widely available and not restricted.

For survival purposes, access to secure water sources has plenty of uses- especially if you are mobile.

Cliff, an all-around good guy, shows just how many of these sillcock faucets you can find in urban areas:

Who Needs a Sillcock Key?

Sillcock keys aren’t just for building managers- they are available for anyone to buy. They are a great tool to have handy if you need to access a public water source or other utility locked down with a square keyhole.

Because of their weight and niche use in public areas, we don’t consider them essential for any type of survival kit. But we have found them useful for a variety of kits and suggest one for this kit:

• Bug Out Vehicles

The rest of the kits we include as a consideration, based on your weight allowance and how frequently you see public faucets day-to-day:

• Car Survival Kit
• Bug Out Bag
• Get Home Bag
• INCH Bag

Personally, I keep one in my car survival kit and bug out vehicle because there is very little drawback to having a key if you aren’t actually carrying the ounces with you.

Sources and References

All of our experience and the testing we do to determine the best sillcock key are useless without listing our research sources and references. We leaned on these for the book knowledge that we paired with our hands-on testing and practical survival experience:

The Final Word

Believe it or not, I used to be a naysayer about sillcock keys. I figured I could just turn the key with a multitool when I needed to. Then when I actually tried that, it was much harder than it sounded. Having the right tool for the job, especially when it is so cheap, is just common sense and can help torque those stubborn faucets that haven’t been accessed in a while.

We presented quite a lot of information, but as always: if you have any questions let us know and we would be happy to help. Our research and testing found the 4-Way Sillcock Water Key to be the best option given its value, durability, manufacturing quality, size/weight, and versatility.

Keep exploring, stay prepared, and be safe.
