Can you Lock a Kegerator? A Guide to Beer Security

Maybe you have an outdoor kegerator or young children, or teenage children, or mooching adult children whatever the reason you have found yourself asking, can you lock a kegerator?  The answer is Yes.

You can put a lock on any draft beer dispenser or kegerator. The easiest way to secure the beer in your kegerator is to install a slide faucet lock. A faucet lock slides over the spout of the tap system and locks the tap handle in place. Another tap beer system security option is a Kegerator door lock, these locks keep your kegerator mechanical systems secure. The final way we recommend to keep your tap system safe is to install a beer line shut off valve, these valves allow you so easily stop flow from the keg to the tapper.

What Kegerator Lock should I Get?

If you have a standard draft spout we recommend the slide faucet lock. These faucet locks are cheap, easy to use and will keep your beer secure.  To use, slide the lock over the spout of the draft dispenser and tilt up, the lock will put pressure on the tap handle. Then turn the key until it sits snugly against the handle. It is recommended to turn the key until the fastener touches the handle, then give the key a half turn to secure the lock. Test the tightness of the lock by trying to pull the tapper forward.  You want the lock to be secure, but not too tight, over tightening the lock can damage the ferrule or the bottom part of the tap handle.

I do have to mention that all locks are keyed the same, so someone can buy a key online for $20 but unless you are fighting a beer thief mastermind a simple slide lock will keep unwanted drinkers at bay.  On a positive note, a universal key allows you to use one key to tighten all locks if you have multiple tappers.

How much does a slide faucet lock cost?

Kegerator locks are not expensive, especially when you take into account the beer you are protecting and/or the people you are keeping safe with the lock. Amazon has draft beer system slide locks ranging from $30.00 to $40.00 per lock. 

Are Slide Faucet Locks universal?

Slide faucet kegerator locks are not universal. There are 5 common draft beer spouts. A standard faucet is what comes with most kegerators. A slide faucet lock will only work on a standard US spout. You will need to know what kind of spout your draft beer system has to get the correct lock.

In addition to the standard faucet there are the Perlick 500 series and Perlick 600 series, the micromatic 304 series and the stout faucets. So what if you have one of the other spouts?  You can still lock a non-standard spout, you will just need to find the appropriate lock. Check out this quick reference image to identify the spout you have and read on to learn more.

How do I Lock a Kegerator with a Perlick series spout?

The spouts on  Perlick 500 and 600 series spouts are too long for a standard slide lock to fit properly.  For this reason we recommend a wrap around tap lock. To use this lock you slide the lock around the shaft of the spout and then raise the lock end to the ferrule or the base of the handle. Next, use the key to tighten the lock so it touches the handle.  It is recommended that you turn it 180 degrees more to secure the lock. 

There are two different wrap around spout locks, the Wrap Around Perlick 500 series lock and the Wrap Around Perlick 600 series lock.  These locks are custom to each spout and are not interchangeable.
