With such a wide range of options on the market it’s hard for us to know what might be best suited for our homes and commercial properties.

Usually we would advise you to go for a like for like lock, but this can still mean a lock upgrade such as ensuring it is of British Standard and meets your insurers requirements.

Multi Point Locks - these are fitted to uPVC doors and are considered very secure and require skills of specialist when fitting

Mortice locks are mainly used in traditional wooden door frames. They are available in a wide range of specs but we would always recommend a BS, 5 lever lock for the best possible security.

Cylinder Locks are another common lock type. You can find these on external uPVC doors generally and are barrel lock placed under the door handle. These can also be used alongside a multi-point lock.

Night latch locks, also commonly known as Yale Locks. However, Yale is a brand. These can be used on wooden doors as extra security in addition to the Mortice lock. These are surface mounted as opposed to being within the door itself. We would recommend a Night latch lock is used alongside another lock for maximum security.

For outbuilding padlocks can also be used as well as key locks. Also not forgetting window locks and digi locks!

With that in mind, we would like you to be as safe and secure as possible in your homes and workplaces. With many people turning their attention property improvements, locks security should be near, if not the top of your list to do. If someone breaks into your property it can be traumatic to say the least and so makes it a worthwhile investment.

All locks to your property should be in good working order and this covers everything from doors, windows and out-buildings. You can also take extra measures such as installing door chains, letterbox guards and security lights.

Checking the strength of your door and frame is a good start. Strike plates can be inserted and can reinforce doors – as there is no point in having the best locks on the market if a potential intruder can kick your door in.

Over time a common issue with uPVC doors is that the door can drop slightly, causing the hooks, rollers and locks in the door to become unaligned. Signs of this could be general stiffness when trying to open and lock the door or the need to push up hard on the handle to lock the door.

Eventually the mechanism in the door will fail as repeated force is used and strain is applied to the multi point locking mechanism the uPVC door.

At JJ Locksmiths, a qualified locksmith will be able to realign your door. At times, the locking mechanisms do fail beyond repair and in the case, we are also able to give you a quote to fit and replace a new mechanism.

Lock snapping is a real threat to your home security and can take just a few seconds for a burglar to snap the lock. This is a growing concern nationwide and requires no knowledge or special tools and so it is becoming more common. This method would break the cylinder and then the cylinder is manipulated to open the lock.

To resolve this problem at JJ locksmiths we advise our customers that they need to be upgrading and changing their locks to anti-snap, British standard cylinders, which we provide. Anti-snap locks, also known as ‘snapsafe locks’ offer the highest level of security and are designed to protect against lock snapping to stop a thief from breaking the lock into two parts. Anti -Snap locks can be fitted to most euro specdoors such as patio doors, wooden & composite, front, back and side doors, aluminium doors and UPVC.

With the absence of government based regulations for the locksmith industry, picking a locksmith does come with risks. Unfortunately, there are too many rogue traders out there who do not have the skills, professionalism or customer service to deal with the lock job you require.

It is vital you look for an independently vetted, inspected and competent locksmith to carry out you locksmithing needs. At JJ Locksmiths we work hard behind the scenes as well as on the job, to ensure we are just that. We are members of the NNAL (The National Network of Approved Locksmiths) and check a trade. Organisations like this are key to help raising awareness of the importance of hiring a recommend trader, such as a locksmith.



When you renew your home insurance, be careful not to overlook the locks on your home. Most insurers will require a minimum standard of lock, being British Standard locks, in good working order on all door and window locks. If your locks do not reach this requirement, now would be a good time to give us a call at Locksmiths to discuss an appointment for a lock upgrade. Don’t forget you not only have to stop intruders entering, but if they do you need to also ensure they cannot escape with your valuable items out of easily opened windows or dodgy door locks.
