How to Avoid Breaking Situations a U lock

A decent U lock from Kryptonite can cost you around a hundred USD. When breaking it, the money gets wasted.

Moreover, there is a risk of damaging your bike while doing the job. So, try not to break the lock. Let’s know what you can do to avoid breaking the lock.

Tip-1: Keep backups or alternatives

While getting a new bike lock, you must keep some backups or alternatives. For example, Kryptonite U locks come with 2 or 3 pieces of keys.

Don’t carry them all at a time. Instead, carry one and keep the other at home for backup. Also, you can make one or more duplicates from a key maker.

Anyways, Kryptonite offers a key safe or combo safe program. You can register here and get your key or combination back once you lose the key or forget the code.

Tip-2: Crack the code

If you are using a combination lock, you can crack it somehow while not opening it.

Well, this suggestion is not for inpatients. If you have the time and patience, then try it. However, you will find numerous videos and tutorials on this.

But most of them are not applicable for Kryptonite U lock. So, you have to do it manually.

Tip-3: Maintain the lock

When the lock itself has problems, it won’t open though you have the keys. So, you must do some maintenance work to keep it from jamming.

However, when the lock is jammed, apply grease to it. Get a suitable lube and apply it through the shackle, key, and all the insertion points.

Then, put the key on and lock-unlock the lock 4 or 5 times. It will help you to make the lock smooth and rust-free.

Anyways, I would recommend Teflon Polylube. It’s effective but gentle towards metal.

You’re gonna abuse me if I don’t tell now how to break a Kryptonite U lock. Again, breaking should be the last step when the lock is not opening. Let’s dig in.

Method-1: Breaking with a hammer

It is the cheapest way of breaking a Kryptonite U lock. But the problem is, the bike may damage if you don’t do it carefully.

So, do it at your own risk. However, you have to get a Compressed Air Can and find a Heavy Duty Hammer before starting.

  1. Firstly, spray the compressed air on the shackle insertion area. Thus, the shackle will get weaken, and it will be easy to break.
  1. Lastly, beat the lock with a hammer until it breaks. Make sure you don’t hurt your hand as well as the bike. 

Method-2: Using shear force

If you have faith in your muscle power, try to break the lock with shears force. It can be a Bolt Cutter or Nailpuller.

Because they produce a massive amount of force that is enough for breaking the shackle.

However, you can simply cut the shackle with the bolt cuter

Or,

Get a couple of nail pullers and push the shackles outward. Do it carefully until the lock breaks.

Method-3: Cutting the Shackle

It’s the fastest and most effective method of breaking a Kryptonite U lock. But, the preparation is a bit costly, and you have to take some hassle.

Yet, it’s almost harmless for the bike. So, you should consider it more. However, a Cordless Angle Grinder will be perfect for the job.

Also, get a pair of Hand Gloves and a pair of Safety Goggles.

  1. Firstly, put on the gloves and goggles. They will protect your hand from rotating blades and save your eyes from the fire spark. Make sure the angle grinder has enough battery backup. Then, you are ready to go.
  1. Lastly, turn the grinder on and cut the shackle. Make sure you don’t push very hard. Otherwise, it can cut your bike passing the shackle. So, cut from such a position where the lock doesn’t have any contact with the bike.
Warning: Before you start the job, make things clear with the concerned authority. When your bike is parked in a public place like a roadside parking area, or basement, you must ask for the administration’s permission. Otherwise, it can be considered a criminal offense. However, your bike’s documents can make it easier.
