Change your locks any time your security might be at risk: moving into a new home, losing your keys, after a break-in, or when tenants change. If your locks are stiff, worn or unreliable, it's also worth replacing them before they fail completely, and older locks that don't meet current British Standards are worth upgrading even if they still work.
Castle Locksmiths can assess your existing locks and advise honestly whether a change is needed. Changing locks proactively prevents bigger problems down the line, and because our vans carry everything needed, the job is usually completed in a single, tidy visit.
Yes, and it should be near the top of your moving-in list. When you buy or rent a property, you have no way of knowing how many keys exist or who holds them: previous owners, their family members, old tenants, cleaners, tradespeople and neighbours may all have copies. Changing the locks on day one is the only way to be certain that you control every key to your home.
It's a quick, inexpensive job compared to everything else involved in moving, and it's also the ideal moment to upgrade to insurance-compliant British Standard locks if the existing ones fall short. We regularly do same-day moving-day appointments across Canterbury, book us in for completion day and move in secure.
Most UK home insurance providers require external door locks to meet British Standard BS3621 or equivalent, a standard that tests locks against common burglary techniques. You can usually check by looking for the British Standard kitemark, a small heart-shaped symbol with a number, on the faceplate of your lock.
If you're unsure, we can inspect your locks and confirm whether they comply. Where they don't, we'll recommend suitable upgrades, new mortice deadlocks, anti-snap euro cylinders, or secondary security features, and explain what the standards mean in plain English. It's not just box-ticking: a non-compliant lock can give an insurer grounds to reduce or refuse a burglary claim.
All major types used on residential and commercial properties: euro cylinders found in uPVC and composite doors, mortice deadlocks on wooden doors, night latches (commonly known as Yale locks), multi-point locking systems, sash locks, rim locks, garage door locks and window locks, plus high-security digital locks where wanted.
Every lock we fit comes from trusted brands and meets British Standards where required, and we can upgrade older locks to modern versions that resist snapping, bumping and drilling. Our vans are fully stocked, so most changes and upgrades are completed in a single visit.
Lock snapping is a burglary technique that targets standard euro cylinder locks, the type fitted to most uPVC and composite doors. By gripping and snapping the cylinder at its weakest point, an intruder can defeat the lock in seconds with basic tools and no skill. It has been one of the most common methods of forced entry in the UK for years, and older cylinders offer almost no protection against it.
If your home has uPVC or composite doors with original cylinders, upgrading to anti-snap cylinders is one of the most effective single improvements you can make. Look for locks rated TS007 3-star or SS312 Diamond, which are designed to break in a controlled way that keeps the locking mechanism secure. We fit them as a quick, affordable swap using your existing door and handles.
Often, yes, and it can save you money. On uPVC and composite doors, the part that your key operates is the cylinder, which sits inside the larger multi-point locking mechanism. If your concern is who holds keys, after moving house or losing a set, swapping just the cylinder gives you a completely new set of keys without touching the rest of the hardware, and it's a quicker, cheaper job.
A full lock or mechanism change is only needed when the mechanism itself is worn or damaged, or when you're upgrading the whole setup for security reasons. We'll always tell you which you actually need rather than defaulting to the bigger job, that honest assessment is a big part of why local customers come back to us.
Yes, in most cases. As long as your door is in good condition, we can fit higher-security cylinders, night latches or deadlocks into the existing door, whether it's wooden, composite, uPVC or aluminium, without major alterations. Where extra security is worthwhile, we might suggest reinforcing plates, hinge bolts or secondary locks to strengthen the setup.
We always assess the door and existing hardware before recommending anything, and we aim for practical, affordable improvements rather than unnecessary expense. A lock upgrade delivers most of the security and insurance benefit of a new door at a fraction of the cost and disruption.
Usually the same day you contact us. In urgent situations, such as after a burglary or lost keys, we offer emergency appointments with response times often within 30 to 60 minutes in Canterbury and the surrounding areas. For planned upgrades, we offer flexible slots to suit your schedule.
The lock change itself often takes under an hour depending on the door and lock type, and because our vans carry a wide selection of locks, most jobs are finished on the first visit without waiting for parts. We'll give you a time estimate when you book so you know exactly what to expect.
