Posted by Luke 20/12/2018 0 Comment(s) Lockers,

There's a problem with your locker. Your stuff is stuck inside. Don't panic!


Looks like Kevin needs help! Lockertek is on hand!


First thing to do, take a deep breath. If you can’t get into a locker then neither can anyone else, so your belongings will stay safe! Speak to a member of staff and they will look for a solution to free up your lock.

If you can’t get the locker to lock when you first use it then choose another locker and let someone know that the locker isn’t working.


But what about if you’re a proprietor? What can you do about faulty locks? Below we look at some of the most common faults with locker parts and how you can remedy them.



The lock isn’t engaging into the lockers frame.


Lock type: Cam lock, hasp lock, some coin locks, combination lock, some digital Locks


Fix time: A few minutes


Tools required: Plyers, Screwdriver if replacement cam bar is required.



When a lock won’t engage into the frame, the most common cause is that the cam bar has been bent out of shape. This can be due to someone using excessive force or can occur naturally over time with a lot of use. The fix is relatively simple for this. Using a pair of plyers to bend the cam bar back into place will usually allow the lock to engage with the frame properly again. In cases where the cam bar can be bent out of shape to an extreme angle. Bending it back manually may cause the cam bar to weaken. In this case, a replacement cam bar for the lock might be the best option! 


The key has broken off in the lock.

Lock type: Cam lock, coin locks, some combination locks, some digital locks


Fix time: A week with delivery of replacement parts



Tools required: Plyers, screwdriver, drill


A fault most commonly found in schools. It seems children are most certainly eating their greens when they have the strength to snap metal keys in half! This can go either of two ways. If the key has snapped off with enough outside of the lock barrel. It may be possible to remove the piece of key with a pair of plyers, then it’s a case of ordering a replacement key. If it’s not enough to remove with a pair of plyers. Then the lock will have to be removed and replaced. For a digital lock such as our universal lock, it will be possible to still use the lock via access codes if a key is stuck but it’s not recommended as you won’t have a manual override if the code is forgotten.


Hasp lock won’t engage, even with the padlock attached.


Lock type: Hasp and staple locks


Fix time: Up to a week with delivery of replacement parts


Tools required: None


This fault is an easy fix and primarily comes down to the type of padlock you are using. All hasp locks for lockers in the UK take padlocks with a shackle thickness of 8mm. Check to see if your padlock matches this thickness. If it’s less then this, then this will be the cause for the lock not engaging. A replacement padlock to the correct specification will soon fix this issue.


The lock's code has been forgotten


Lock type: Combination lock, digital lock


Fix time: A few minutes up to a week if a master key is required


Tools required: None 


We’ve all done it, forgotten our lock code, our pin code, our nan’s birthday. Sometimes those sequences of numbers just elude us! Luckily, there’s a few options here to rectify a lock code that can’t be remembered. For mechanical combination locks, a master key is the best option.  These master keys don’t open the lock but help to find the previous code and unlock the lock, so a new code can be reset.  Digital combination locks can be unlocked via a master code to allow them to be reset if the code is forgotten. There is the master key option for these digital locks but be aware that these keys will open the lock, but they won’t reset the code.


I get no response from my digital lock when entering a code


Lock type: Digital locks


Fix time: A few minutes


Tools required: Screwdriver


The most common reason for a digital lock not responding from input will be that the batteries in the lock have fully drained. To fix this issue you simply need to open the locker and unscrew the lock from the back. This should allow you to swing the lock away from the door enough to replace the batteries without having to remove the entire lock itself. If your flat battery is not allowing you to open the locker. Then a master key should help you get it open to replace the batteries.  Even keyless locks come with various methods to unlock a lock without any power.


My coin lock is jammed and won't lock


Lock Type: Coin locks


Fix time: A few minutes


Tools required: Possibly a screwdriver


Coin locks, if the correct coins for that lock are being used, are one of the most fail-safe types of lock but sometimes you can find that the lock might be jammed when a coin is inserted. This is common if the coin locks have a coin retain box attached. If the box isn’t emptied, the coins pile up in the box until eventually they can get stuck inside the coin lock mechanism. The simple solution to this conundrum is to empty the coin retain box either by an included key or via a screw fixing.


My locks are stiff and aren’t turning properly


Lock type: Cam lock, hasp lock, coin lock, mechanical combination locks


Fix time: A few minutes


Tools required: Lock lubricant


When receiving new lockers or new replacement locks for existing lockers sometimes the locks can be stiff when trying to unlock them. This is will loosen over time as the lock is used. If you are wanting to fast track this process, then a little extra spray lubricant such as our lock lubricant will allow the locks to move freely.
