Question about Master Lock Bicycle Lock

1 Answer

I did not close the lock all of thwe way on my Master coil type device. I spun the tumblers and realized that it was only 3/4 of the way in and pulled. It locked in that position and no amount of dialing the combo will open it. This includes starting the first three number from the second through fourth position. I thought that I've done that before with no problem, but guess not.Any clues? Thanks

Three Tips on Choosing Pin Tumbler Locks

Recently, break-ins happened in Harbin City and the burglars broken into houses with the help of tinfoil. This kind of technology is aimed at unlocking the pin tumbler lock which is widely used by residents. It has the high unlocking rate and a pin tumbler lock can be unlocked within about ten seconds.An investigation showed that the two suspects stole cash and anything valuable from high-rise residences by tinfoil and unlocking tools when householders went to work or went out. Their targets mainly were residents whose doors were equipped with cross-shaped or line-shaped security door locks. However, the two suspects said that they could also unlock the crescent-shaped (arc-shaped) locks.It is hard to prevent the pin tumbler lock from being unlocked by the tinfoil. Recently, a reporter visited several stores and markets and found that there were a variety of locks on the market. When the reporter asked about the theftproof performance of the lockers, owners of these stores continued to introduce the locks' features such as the high technology. However, when they were asked whether the locks could prevent security doors from being unlocked by tinfoil, no one could make a commitment. A person who once was a thief told the reporter that although there are various locks on the market, the most commonly used locks can be generally divided into pin tumbler locks, blade locks and electronic locks.Because of the low prices, pin tumbler locks are widely used for security doors. For now, the pin tumbler lock's usage is around 70%. Due to its design structure characteristics that the tumbler end is exposed and the working stroke is short, the tumbler can be touched directly by foreign bodies like wire hooks so as to be technically opened. However, the quality of pin tumbler locks on the market also vary from each other. If people do not know the methods of choosing the good pin tumbler locks, it is likely that their doors with the inferior pin tumbler locks will eaily be broken into.Here are three tips for you to select the pin tumbler locks with the superior quality.OpenInsert the key into the half of the lock's keyhole, then gently turn the key and push it in at the same time. If the key can be pushed in the keyhole successfully, then the pin tumbler lock has good security performance.LookWhen buying a pin tumbler lock, people should choose pin tumbler locks that have brand authentication and excellent theftproof performance. Do not buy pin tumbler locks from less known and less creditworthy hardware stores just because of petty gains.AskTo know whether the pin tumbler lock you buy has good security performance or not, you can call a lock company and ask how long it will take to unlock a certain type or brand of pin tumbler lock. If they tell you that it is easy to open it, then do not buy it.

I forgot the combo for my Kryptonite bike lock US PAT 593412/6422051, can you please help? Thank you

Another way is to pull apart the ends till you have tension on the tumblers. As you place tension try to turn the tumblers. As you feel each loose or tight tumbler is how you can find your combination. I open this type of combination lock like this all the time. First look for the tightest tumbler, turn it until it feels looser and next look or feel for the next tight tumbler. All the tumblers do not block the release at once. You are looking for the first tumbler to adjust, the tightest one, then the next, continuing until you find you have released all the tumblers. This has worked for me with any brand of inline tumbler release system out there. Good luck, usually takes me about 10-15 minutes to find the code. This method can be used on regular locks with a changeable combination as well. It will just take a little time to get to know how much tension to use as you go through each tumbler. Similar as to how you pick a regular lock system. Good luck, definitely doable.

Master Lock 34AT trailer coupler lock. key turns tumbler 90 degrees, but lock wont remove. I don't know if i'm supposed to use another tool (like allen wrench) for pinhole in bottom. Is there...

1. Insert key in cylinder and turn to right.
2. Slide trailer lock over side flanges of coupler as far as it will go.
3. Insert allen wrench (or screw driver) into opening at bottom of lock and turn it to right until hardened set screw is tight against inside of coupler. Remove wrench.
4. Turn key to left and withdraw it. Opening for wrench is now blocked.
(To remove lock, merely reverse above steps.)

We tried to rekey our kwikset smart key, but couldn't and now the original key doesn't work

I had mine do the same thing right before I was leaving to the airport [re-keying for the house-sitter]. I was setting the lock and I hear a spring-type ping and the keying was lost.

The tumbler can be reset to your key. However, it involves disassembling the device and has small parts.If you are feeling lucky, you can do this yourself or take it to a qualified person.

If you are feeling lucky:
A: Disassemble the lock from the door

B: Remove the door handle from around the key side.

C: Remove the U retaining-clip from the outside of the lock that is securing it to the shaft.

D: Remove the lock from the shaft

E: Remove the U retaining-clip from the tumbler body and the case
F: You will have to press the five fingers down evenly on the length of the case to slide the cylinder out of the case. (I cut a plastic card with small wire cutters to make a tool, but you could probably use thick card-stock and some scissors.)

Be careful; you will have to watch for and secure the check ball on one side of the tumbler and the finger lock bar on the other side as you slide this out.

G: Remove and store the check ball securely as well as the finger lock bar. (careful with the plate surrounding the fingers that the finger lock bar resides in)

H: Remove the finger locking plate. Carefully, make sure the fingers are still inside and oriented correctly and the spring at the back of the finger locking plate is left in place.

I: You will notice a u channel groove in the fingers and the finger locking plate. Align the fingers in the finger locking plate evenly so that the grooves in the fingers match the groove in the finger locking plate.

J: Replace the finger locking plate with fingers aligned evenly with the u channel groove back onto the tumbler body and hold back against the spring left on the rear of the tumbler body. This puts the tumbler into re-key position.

K: Replace the finger locking bar onto the finger locking plate while holding the assembly against the spring and tumbler body. (If this is done correctly, the finger locking bar will now be flush with the side of the finger locking plate and not raised as normal.)

L: While holding the tumbler assembly together and maintaining the locking plate pressed against the spring, Insert your new key into the tumbler body.

M: While holding this assembly in this position, add the check ball to the tumbler assembly.

N: While holding the assembly in position, slightly depress the black plastic block at the back of the finger locking plate and slide this tumbler assembly back into the tumbler case taking care to rotate the case 90 degrees clockwise from normal. (Note the U channel groove inside the tumbler case that normally receives the finger lock bar and use that for orientation.)

If the tumbler does not insert cleanly, verify the finger locking bar is flush. If it is not, redo while maintaining proper pressure to keep the finger locking plate firmly against the spring in re-assembly. Also, verify the fingers are not protruding from the tumbler body. If they are, redo the procedure taking care to align the fingers properly on assembly and maintain proper force on the finger locking plate against the tumbler body during re-assembly and new key insertion

O: Rotate the key and tumbler body in the case to the normal position (counter-clockwise 90 degrees).

P: While holding the tumbler body firmly against the case, remove the key.

Q: Re-insert the key and verify smooth rotation.

R: Align the tumbler body and case back to the normal position and while holding the tumbler body firmly against the case, remove the key.

S: Replace the U retaining-clip that belongs on the back of the tumbler body to secure it within the case.

T: Replace the tumbler body in the main lock shaft and secure with the shaft U retaining clip.
