Post Revisited - How To Repair Door Closers

This post originally appeared in May 2009. It has become one of the most widely viewed posts on our website.

Repairing door closers is not too difficult, even if you are only slightly mechanically inclined.


Blogging often involves many labor intense hours of writing and researching, especially if you are composing your own original works.

I try to acknowledge the source of my reference in most if not all articles written here.

This next post is actually by well respected Author and Locksmith Tom Rubenoff and the source of this article is from Hubpages.

Door Closers

This article is primarily about surface mounted door closers, but the ideas herein can be applied to other kinds of door closers as well.

Door closer adjustment is an art that requires knowledge, patience, and an ability to climb up and down a ladder several times, but with these attributes and the appropriate wrench, hex key or screwdriver, you can do it yourself.

Most of the adjustments are implemented through the opening or closing of hydraulic valves. When it comes to turning the screws that operate these valves, a little goes a long way. A turn of 5 degrees can significantly increase or decrease closing speed.

CAUTION: DO NOT COMPLETELY UNSCREW DOOR CLOSER HYDRAULIC ADJUSTMENT SCREWS OR YOU WILL RUIN THE CLOSER AND VOID THE WARRANTEE.

Also, hydraulic fluid will leak out of the closer and make a mess. This will make you unpopular.

A door closer is a mechanical device designed to close a door slowly, but firmly enough to latch. It accomplishes this by using spring tension modulated by hydraulic fluid. As the user opens the door, hydraulic fluid passes from one reservoir to another, and as the spring pushes the door closed again, the hydraulic fluid passes back to the previous reservoir through a series of valves that control the speed.

The illustration at right shows the effects of the common hydraulic adjustment controls available on most commercial grade door closers. Controls for swing speed and latching speed control how fast the door closes, and many closers also feature a hydraulic control for back check that controls the last few inches of the opening the door so as to prevent the door from being slammed into an adjacent wall.

• Swing speed adjustment controls how fast the door closes from fully open to within about 5 degrees of closed
• Latching speed adjustment controls how fast the door closes for those last few inches
• Back check adjustment controls the amount of resistance to opening the door past a selectable point

The illustration below shows the various hydraulic control valves. These might be located in many configurations, but you will usually see the back check control located somewhat away from the latch speed and swing speed controls.

There are also door closers equipped with an additonal valve for Delayed Action. Delayed action closers hold the door open for a longer period of time to allow persons with disabilities more time to get through the door.

Also notice the Spring Tension Adjustment in the illustration above. Spring tension controls the "size" of a closer. The term is misleading, because it does not actually have anything to do with the physical dimensions of the closer. Size is determined by the width of a door. "Sized" closers, that is, closers that have a factory pre-determined spring tension for a particular door width, have no spring tension adjustment. Many door closers today are "non-sized", indicating that spring tension can be field adjusted to fit the size of the door.

It is tempting to use the spring tension adjustment to solve problems, for example, in positive pressure situations where air flow is preventing the door from closing properly. However, the tighter you make the spring, the harder it will be to open the door. It is possible to tighten the spring tension to the point that some people will not be able to open the door.

Adjusting the Door Closer

To adjust the door closer, bring a step ladder tall enough so that you can easily reach the door closer from the second or third highest step. Climb the ladder and examine the closer. If you can't see adjustment screws, chances are the closer has a cover. Usually the cover is plastic, but it could also be metal. If you see no fasteners holding the cover on, that means the cover is held on by tension. Pull it off. If you do see fasteners, usually you can loosen, but not remove, the fasteners and the cover will slide off.

If you find that there is oil in the cover or oil on or leaking from the closer body, you can stop right now. You need a new door closer. If, however, it is not leaking, you can proceed.

Now that you have the cover off, you should be able to see the adjustment screws. If you are lucky, they will be marked on the closer body as to what they are or there will be a diagram inside the cover. If not, you may have to experiment a little to see which is which. Remember, when it comes to turning door closer adjustment screws, a little goes a long way. Start with no more than 1/8 of a turn. Turn the adjustment screw clockwise to slow the door closer down, counter-clockwise to speed it up. then get down off the ladder and observe the effect.

Open the door and watch it close. If it closes right the first time, check it 10 more times. If it closes correctly every time, you're done. If not, go back up the ladder and make another adjustment, etc., until the closer is doing what you want it to do. When it closes the way you want it to 10 times in a row, it will probably continue to do so.

Ideally a non-delayed action door closer will close and latch the door in 7 to 8 seconds.

Problems

If you expect a door closer to consistantly close the door, as a prerequisite the door must close properly. If there is a hinge problem, a warped door, or the door must swing uphill to close, a door closer will only go so far in solving the problem. Sometimes a door must be repaired before it will close and lock automatically with a door closer.

In vestibule conditions, where you have an exterior door, a small space, and then an interior door, the trapped air between the inside and outside door can be a factor. You may have to adjust both closers to get both to work correctly. Wherever air pressure is a factor, including negative or positive pressure situations, I have have gotten door closers to close and latch the door consistantly by adjusting them to a slow swing speed and a somewhat fast latch speed. The slow swing speed seems to give the air a chance to get out of the way and the fast latch speed gives it a very slight slam at the end to make sure it latches.

Trouble Shooting

• If oil is leaking from your door closer, throw it away and buy a new one.
• If your door closer is slamming the door and cannot be adjusted to do otherwise, either the fluid has leaked out or the valve seals are worn out. Either way, your best option is to replace it.
• If the closer stops closing the door before it's closed all the way, or actually spings back when you try to manually shut the door, the arm is probably installed on the shaft incorrectly. Download the instructions from the door closer manufacturer's web site and see if it is installed correctly.
• If the arm makes noise and bounces up and down while the door is in motion, tighten the fasteners that hold the arm to the closer, to the header, and at the knuckle that holds the two parts of the arm together.
• If the door closer has no spring tension and the spring tension adustment turns round and round with no effect, the spring is broken the door closer must be replaced.

Kwikset Smartkey Problems.... (Update)

8/23/2018 UPDATE: We just updated the video above to a better video from our colleague Terry Whin-Yates.

The original post, including many comments from viewers can be found here.

The post in the link above is by far, the most popular and frequently viewed post on this website.




Came across an interesting blogpost today that has several comments by product users, all complaining about similar problems shortly after installing Kwikset Smartkey locks.

One such comment by a poster....

"Our smartkey failed this evening. We locked both deadbolt and door as we left, came home to locked out. I called kwikset and after working with them on the phone trying to wiggle the key to the 1/4 turn position to try and get it to the learn position – nothing worked. The customer support person said since we had keys duplicated using the grinding method instead of having a locksmith stamp them out the keys had made the cams in the lock out of alignment. I asked CS how we will get in if we are on the OUTSIDE wanting in and he said we would have to either find another way in or drill out the cylinder. They are sending a replacement cylinder. No thanks – I don’t want to take the chance."

Another...

"My husband just bought this and installed it yesterday. While “rekeying” to our key, it stopped working! Now both the key that came with it doesn’t open the door nor the new key. I was looking for the company’s website for troubleshooting the problem and found this! Glad we kept the receipt as this installation is not continuing! Thank you all for commenting! You are saving more people from getting ripped off with this lock!"

Another...

"What a nightmare.My baby boy moves out to his first house and buys the kwikset smartkey to assure his security.comes home one night,pouring down rain and 28 degrees outside cant get in the house the key doesnt fit the lock .He has to sleep out in the car all night long.what a nightmare.never again will a smartkey be bought especially $80.00.there needs to be a recall on the kwikset smartkey.what a let down."

Another...

"What a joke, installed YESTERDAY, worked perfectly fine until coming home today with groceries and a 6 month old, to find out our key no longer worked. Was told by customer service that this is NOT an issue and people do not have this problem (Obviously I told him to check this website, because he was wrong)

Option one, I can take the deadbolt off my front door to bring to Home Depot and have them fix the lock, which would leave my house unsecure as there would be NO lock on my door. The other option is to wait 5-7 days for a new lock from them. He said the new lock they will send me is more efficient then the one month old lock already installed and he guarantees it will not have this problem.

In the meantime, how the heck am I supposed to get in and out of my house if my lock doesn’t work?

WHAT A JOKE! Take these stupid things offffff the market"

Another...

" I received the new smart key cylinder from

Kwieset and installed it on the front door. From the get-go I had problems, only some of the existing keys worked. Bought new keys and they seemed to work better for a short time. Now they are giving me problems. I have to jiggle them inside the lock to unlock the door and even now they are giving me problems. Finally I had enough: no trust in the lock and never knew when I would be locked out again. I took the smart key cylinder out and installed the old lock, which is a non smart key. At least now I have peace of mind that it will always work. I am keeping the old smart key locks, because I know with all the problems that everybody is having, there has to be a recall and maybe I can get my money back, but I will not hold my breath. Keep complaining to Kwikset about the so called smart key. I wasn’t very smart to buy it in the first place."

Many people seem to think that locksmith services are too expensive. In fact locksmith services are often cheaper than purchasing the DIY products from the big box hardware stores, because locksmiths have taken the time and training to master their product lines. Installation, service, maintenance all taken care of by a true technician with experience in the field.

I understand the perception that DIY is often cheaper, but realistically the locksmith (one of the oldest professions) has deliberately trained to service, advise and protect consumers from the poor advice and suggestions often received at the big box stores from untrained, unknowing part time sales assistants.

I regularly see both Kwikset Smartkey and Schlage Securekey products in the field. Often they are purchased by consumers at the big box hardware stores because most locksmiths refuse to stock them.

I can easily reset the tumblers for clients, often because they have lost the reset tool for the Kwikset or are simply unaware that the process is uncomplicated. The Schlage Securekey is a little more complicated process to re-key, but this is because many customers no longer have access to the blue reset key.

For the better (and often cheaper) products, visit your local locksmith today and find out the why's and how's behind purchasing suitable functional and correct locking systems and products.

Tariffs On Chinese Steel Cause USA Based Safe Manufacturer To Close Shop And Move To Mexico

Stack-On Safes, a Chicago based manufacturer of high quality safe and storage solutions, that has been offered through locksmiths for many years, has decided to close it's two local manufacturing facilities. The closures will eliminate almost 150 local jobs and move the companies manufacturing operations to Mexico.

The decision has not come lightly for Las Vegas based parent company Alpha Guardian, who believe that the recent introduction of tariffs on Chinese metals is a large contributing factor to the decision.

The tariffs announced in June, are making local USA based metal products manufacturers at odds with the federal government, who are attempting to bring back local metal manufacturing to this country.

Unfortunately, local based metals manufacturers cannot produce the quantities of metals, at sufficient cost points, to enable companies like Stack-On to continue to be competitive in the marketplace.


 Stack-On produce some innovative and high quality safe and storage products that are recommended and demanded by swathes of local locksmith companies, sporting goods suppliers, gun clubs, among others in the wider marketplace.

Critical to their business model is the cost of raw materials, chiefly steel. The recent introduction of 25% tariffs has turned their business model from a profitable venture into a loss.

Whatever your chosen political affiliation, it is important to understand the pros and cons of tariff applications and be aware that many countries can be economically affected by ignorant policies that cause upheaval to businesses, communities, employment and consumers.

Controversial Opinion In New Article Suggests Why NOT To Recommend Or Buy An Amazon Echo Smart Speaker

A new article has appeared that discusses the authors reasoning about why you should think twice before purchasing an Amazon Echo smart speaker.

A group of hackers at the recent hacker convention Defcon Security Conference in Las Vegas, presented a discussion about the ease in hacking the Amazon Echo and using it to "listen" (spy) on anyone speaking within it's vicinity.

Apparently (and reasonably), the researchers informed Amazon in advance about their findings, prior to making the presentation at the conference.

Amazon had implemented a patch for their top selling product after being informed and a spokesperson for Amazon advised that the vulnerability required physical access to the product, to enable the hack. The security patch was released in July.

Of concern, is the fact that the researchers DID NOT have physical access to the devices in question. They only had access to the LAN (Local Area Network).

The article appears in the source below.

The reason we include this article in our site, is because Amazon Echo devices and other smart speakers are increasingly being used to operate smart home product including (but not limited to) electronic door security products, deadbolts, alarm systems, cameras.

Personally, I feel that the article should have been worded differently and that authors should think hard before directly vilifying another company's product offering.
