1. Find out which part of the bike lock is stuck

Bike locks tend to get stuck in two places:

  1. in the keyhole so you can't turn the key
  2. in the body so you cannot separate the two parts of the lock.

How to keep your bike lock from getting stuck (1)

Bike locks tend to get stuck in 2 places

How can you determine where the problem lies? It's easy...

If the key doesn't fit all the way into the lock or doesn't turn properly, the problem is obviously in the keyhole!

But if the key slides in easily and spins freely, but the bike lock still won't open, then the problem is probably where the two parts of the lock meet.

A stuck keyhole can be caused by dirt and debris, frozen water, rust, or simply misaligned washers.

On the other hand, if the bike lock won't come loose, then corrosion build-up has usually fused the shackle or bar to the inside of the lock.

Once we know what the problem is, we can start fixing it...

2. Attack the stuck area with WD-40!

WD-40 can be a miracle cure for all kinds of stuck locks. It removes dirt and debris, removes rust, loosens the mechanism and loosens corrosion that has melted the shackle or bar together.

How to keep your bike lock from getting stuck (2)

Whatever is causing your bike lock to stick, WD-40 should be your primary tool to fix it!

Often a squirt or two on the problem area is enough to get the job done. But let's take a closer look at specific issues...

If the keyhole of the bicycle lock is stuck

misaligned cylinder discs

This is probably the most common cause of stuck bike locks. And luckily (usually) it's pretty easy to fix.

The most obvious sign of this problem is that the key does not fully fit in the keyhole. But to fix that, we must first understand why it's happening...

A bicycle's locking mechanism contains several rotating disks, one above the other. To lock and unlock the bicycle lock,atof the disks must be rotated simultaneously in the same direction.

Take a look at your bike lock keyhole and you should be able to see what I'm talking about!

How to keep your bike lock from getting stuck (3)

If these discs are misaligned, the bike lock cannot be locked or unlocked.

Turning the discs is the job of the key. And to do this, the key must be insertedatthe way to the keyhole so that it goes through the holes (and hooks).atthe disks

If the key doesn't fit completely into the keyhole, you won't be able to turn all the discs and lock (or unlock) the bike lock.

Problems start when the holes in the bottom washers don't line up with the holes in the top washers as this will prevent the key from being fully inserted.

So to fix this problem, all we have to do is realign the disks!

As with most keyhole problems, dirt, grime, and rust aggravate the situation by making the disks stickier and more difficult to turn.

So task one is to fluff them up with some WD-40! Hold the lock with the keyhole facing the ground and spray WD-40 into the hole. This should remove road debris and allow it to drain out of the locking mechanism.

How to keep your bike lock from getting stuck (4)

Spray WD-40 liberally into the keyhole

(Video) How to Fix a Stuck Bike Lock

Then turn the bike lock so that the hole is facing up and insert the key. Twist the key back and forth and try to gently push it further into the locking mechanism while the discs realign.

Once the key is fully seated in the locking mechanism, it must turn freely and fully for the lock to open. This may take a little while, but usually works over time.

How to keep your bike lock from getting stuck (5)

It may be easier to realign the drives with a small flat head screwdriver.

If you're having trouble realigning the washers with the wrench, try a small flathead screwdriver. It's usually thinner than the key, giving you more control. Extra WD-40 helps too!

Armed keyholes

If the key goes all the way in but won't turn, the locking mechanism may be full of dirt and debris. Or maybe it has started to corrode. So...

Apply some more WD-40 the same way as above! Insert the key, turn it, then remove it between spritzes of WD-40. If it doesn't work right away, try again. And again. Usually this will work eventually.

How to keep your bike lock from getting stuck (6)

More WD-40!

Whatever you do, don't lose your temper and try to force it. Then the key breaks in the bike lock!

Keys are in keyholes

If your key is stuck in the keyhole and you can't get it out, then the solution is the same as above: lots of WD-40 in betweensofttries to turn the key back and forth.

Spraying a dose of WD-40 into the hole and then letting it sit for 5-10 minutes can do wonders.

As above: It is important that you do not lose your temper and try to force the key. Then the key will break and your problems will be much worse!

frosted keyholes

Of course, if you think your bike lock is stuck because water has frozen in the lock mechanism, you need to melt the water before it unlocks...

Sometimes it is enough to breathe through the keyhole. If not, you can try heating the key with a lighter or match and then gently pushing it into the locking mechanism. You may have to do this multiple times.

Of course, if that doesn't work and you get the bike lock in, that will eventually melt the ice.

How to keep your bike lock from getting stuck (7)

But spraying the locking mechanism with car windshield deicer might get faster results. Or I've heard of people using antiseptic handwash too!

Whichever method you use, make sure the lock hole is completely dry before using it outdoors again or it will freeze again.

When the bike lock body is stuck

If the key goes all the way in and turns smoothly but the bike lock still won't open, corrosion has likely fused the two parts of the lock together.

How to keep your bike lock from getting stuck (8)

Spray WD-40 liberally into the pivots where the shackle meets the bar

In this case, try spraying a lot of WD-40 into the joint. You'll probably have to let it sit for a while for the WD-40 to work its magic. If possible, soak the bike lock in WD-40 overnight!

The WD-40 should dissolve much of the corrosion, allowing you to separate the two parts of the bike lock.

But if it's still stuck, you can also get it to smack your palm hard on the shackle or bar (or tap it lightly with a hammer) in the direction you want the lock picked.

It is advisable to cover the bicycle lock with a towel beforehand so that the hammer does not damage the housing!

How to keep your bike lock from getting stuck (9)

It may be helpful to "tap" the temple or body with a hammer.

What to do if your Kryptonite, OnGuard or Abus bike lock is stuck?

Well the truth is that the basic principles are the same for all bike locks. But there's a big difference in the way the three companies tackle the problem of stuck locks!

Kryptonite locks

Kryptonite has an excellent reputation for customer service and it really shows in the way they deal with stuck bike locks. For starters, there is a lot of useful information on their website...

For example, if you cannot lock your padlock,they suggestMake sure the "rib" (the silver metal feature on the temple that hooks into the frame mount) has not slipped into the nose of the temple.

How to keep your bike lock from getting stuck (10)

The slot can slide down and prevent the hanger from getting caught on the crossbar.

(Video) How To Keep Your Bike Safe | A Guide To Preventing Bicycle Theft

In this case, the shackle may be prevented from being fully inserted into the crossbar, causing the U-lock to not lock! Positioning the tab higher on the shackle and tightening the screw that holds it in place should quickly fix it.

And if your key breaks in a Kryptonite lock, you can have the key removed by a locksmith, send the lock, key, key number and locksmith bill to Kryptonite andThey will refund your bill and send you a new lock!

However, in general, follow the same 2 steps to fix a stuck Kryptonite bike lock as you would any other bike lock.

OnGuard locks

You won't get customer service like this from OnGuard! And like many of the cheaper lock brands, I find that their mechanisms need a little more maintenance to keep them looking good.

So while the steps to repairing a stuck OnGuard lock are the same, once it's repaired, I recommend cleaning and lubricating your OnGuard lock more frequently than other locks to prevent further problems.

Misuse of padlocks

Likewise, the abuses aren't particularly helpful when it comes to pinching their bike locks. However, Abus locks are so well made that they have fewer problems to begin with.

For example, in my experience, it's much more difficult to accidentally misalign the washers on an Abus lock!

If you're having trouble, try the same 2 steps I recommend for other bike locks. And once you get it working, remember that Abus recommends making your ownPS 88 fuse spray [Amazon]to keep your locks in good condition.

This is how you prevent your bike lock from getting stuck again

Once you've unlocked your bike, you'll want to avoid all that frustration and stress in the future!

And thankfully, there are several things you can do to seriously reduce the chances of your bike lock getting stuck again...

1. Clean and lubricate your bike lock regularly

This is by far the most important thing you can do. And I can guarantee most of us don't do it enough. In fact, I'm guessing most people have never cleaned or lubricated their bike lock.

But we should. A good cleaning and lubrication from time to time never hurt anyone! So try to find time for this process at least every 6 months.

And so that you don't have any more problems, be sure to treat both locking mechanismsjthe body where the two parts meet.

How to treat the bike lock keyhole

Clean the locking mechanism withWD-40 [Amazonas]. Turn the lock so the keyhole is facing up, then spray the WD-40 into the cylinder until it comes out.

Then turn it so the keyhole is facing down and the WD-40 will spill out. This should displace water, dirt, grease, scale and rust.

For really dirty bike locks, you may have to repeat this several times. Inserting, turning and gently removing the key between sprays will remove dirt.

Once the lock is clean you should do itforeversmear it. But never use WD-40 for that...

WD-40 is a cleaning agent that displaces water and ultimately removes any existing lubricant. It is ideal for cleaning a bicycle lock. And it's great for releasing a stuck bike lock. But will benoensure long-term lubrication.

How to keep your bike lock from getting stuck (12)

Instead, use a suitable Teflon-based lubricant such asFinish Line [Amazon]ÖTriFlow [Amazon].

These work well at low temperatures and repel moisture to reduce the risk of corrosion and freezing. Put a few drops on the locking mechanism and dose by inserting and turning the key.

Some people recommend graphite-based lubes for bike locks. These are good for dry environments. But bike locks are invariably exposed to moisture, which tends to turn the graphite into a goo that collects dirt and then jams the locking mechanism.

Then use WD-40 for cleaning and TriFlow or Finish Line for lubrication. Use these regularly and you'll have far fewer problems with stiff, unresponsive locking mechanisms and your bike locks will last much, much longer.

How to treat the bicycle lock body

You shouldn't have to clean the body of the bike lock too often. Periodically clean the shackle ends and lock holes with a rag.

How to keep your bike lock from getting stuck (13)

Clean and grease all connection points of the two parts.

However, it is important that the points where the shackle meets the body are lubricated and free from corrosion. Especially in cold or humid climates. This will prevent the hanger from sticking to the body.

White Lithium Grease [Amazon]intakeThe shape is good for this because it's thick, doesn't run, and lasts a long time. Apply to both ends of the rod and the holes in the body as needed.

2. Do not turn the key until it is fully inserted!

All bike locks will bind if you try to turn the key before it is fully seated in the keyhole. As I mentioned earlier, most bike lock mechanisms contain a series of discs, all of which must be rotated fully before the lock will open.

If you try to turn the key before it is fully inserted, you will not catch the discs on the bottom of the cylinder, preventing them from turning and opening the bike lock.

Once this is done the washers are misaligned and you will not be able to fully insert the key and open the bike lock until you realign them (see above).

3. Buy a good quality bike lock

Cheap locks are false economy. Or your bike gets stolen because it offers such poor protection. Or your bike lock starts to stick because it's not properly waterproof and rust starts to clog the locking mechanism or weld the shackle.

Either way, sooner or later you will have to buy a new bike lock!

Instead, get it right the first time. Invest in one as much as possibleGood quality bike lockand it should last for many years.

With that in mind, the best locks are made by Abus, Kryptonite, and OnGuard. I have writtenmuch more about each of these brands, but if you are looking for the best quality, choose Abus.

How to keep your bike lock from getting stuck (16)

Abus are a particularly good option if you live in a place with a harsh climate. Its locks are subjected to a whole series of tests at temperatures as low as -40 degrees.

And to study its corrosion resistance, they also use a saline air chamber that ages every bike lock inside for a year for every day. No other manufacturer tests its locks so rigorously.

You should also buy a bike lock with a key cover. Key covers can prevent dirt and debris from entering and clogging the mechanism. But be careful as they can also trap water which can then freeze and then block the lock!

Summary on repairing a stuck bike lock!

Many of the problems we have with stuck bike locks are avoidable. Buying a good quality bike lock, cleaning and lubricating it regularly, and making sure the key is fully inserted before turning will avoid most problems.

And you will be much happier.

However, modern bike locks are complex and precise instruments and sometimes they just get stuck!

The key here is to remain calm and be patient. ManyWD-40 [Amazonas]and a light banter in a warm environment usually suffices in the end!

If not, and the problem lies with the key, read up on my adviceHow to open a bike lock without a key.

But if you just can't open it, you probably need a new bike lock. If so, check out the 3 simple steps that will ensure youChoose the best lock for you and your bike.
