The boxes can wait. One of the first jobs after getting the keys should be sorting the locks, because you rarely know exactly who still has access to your new place. Previous owners, old tenants, cleaners, tradespeople, neighbours and family members may all have had copies at some point. That is why this guide to changing locks after moving matters – it is one of the quickest ways to make a new home feel properly yours.
For most people, the question is not whether to do it, but how much needs changing and how quickly. The honest answer is that it depends on the property, the locks already fitted, and whether there are any signs of wear, poor security or missing keys. In some homes, a straightforward lock change is the right move. In others, rekeying or upgrading to better security makes more sense.
Why changing locks after moving is worth doing
When you move in, you inherit more than walls and keys. You also inherit the property’s security history, and that is usually the part no one can fully guarantee. Even if the seller or landlord hands over every key they know about, they cannot always account for copies made years earlier.
This is especially relevant if you have moved into a rental, bought an older property, or taken over a commercial unit where staff turnover has been high. In those situations, relying on existing keys can leave a gap in security from day one. A lock change closes that gap quickly.
There is also the practical side. Many locks are already tired by the time someone moves out. Stiff cylinders, worn mechanisms, temperamental uPVC door locks and doors that need a hard push to engage are all common. If the lock already feels unreliable, moving day is a good point to deal with it before it becomes a lockout.
Guide to changing locks after moving – what to check first
Before replacing anything, take a careful look at every entry point. Start with the front and back doors, then side doors, patio doors, French doors, garages, outbuildings and accessible ground-floor windows. If the property has a porch or internal door that separates living space from another entrance, include that too.
You are looking for two things: control and condition. Control means knowing how many keys exist and who might have had them. Condition means checking whether the lock works properly, meets a reasonable security standard and suits the door it is fitted to.
If you notice loose handles, keys that stick, cylinders that protrude too far from the door, misaligned keeps or damage around the frame, those are signs not to delay. They can point to poor fitting, wear, or in some cases a previous attempted break-in. A new lock alone may not solve every issue, but it is often the first step.
Should you change the lock, rekey it or upgrade it?
This is where a lot of people overpay or choose the wrong option. Not every move calls for a full replacement of every mechanism.
Changing the lock means replacing the existing cylinder, mortice lock or mechanism with a new one. This is usually the best option if the current lock is damaged, outdated or not giving you much confidence.
Rekeying means adjusting the lock so old keys no longer work, while keeping the existing hardware where suitable. This can be a cost-effective option if the lock itself is in good condition and compatible with rekeying. It is often useful for landlords, businesses and households that want control over access without changing every visible fitting.
Upgrading the lock is the right call when security is below standard. That might mean fitting anti-snap euro cylinders on uPVC doors, replacing a basic rim cylinder, or moving to a higher-security option that offers better protection against common methods of attack. If you have just moved into a property with very old or budget locks, spending a bit more now can save a lot of grief later.
The locks most homes in the North East tend to have
In Wallsend and across the wider North East, many homes have uPVC doors with euro cylinder locks. These are common, practical and quick to service, but they are not all equal. Older or lower-grade cylinders can be vulnerable if they are not the right type for the door.
Timber doors often have mortice sashlocks or deadlocks, sometimes alongside a night latch. These can still offer good security when properly fitted, but older versions may not meet current expectations.
Newer properties may already have decent hardware, while older terraces, flats and converted buildings can be more mixed. One door may be well secured and another may be the weak point. That is why a whole-property check is always better than only changing the front door and assuming the rest is fine.
How quickly should you do it?
Ideally, on the day you move in or as soon as possible after. If that is not realistic, make it one of the first jobs in your first week.
Urgency goes up if the keys changed hands through multiple people, if you are missing keys promised during the sale or tenancy, or if the property has been empty for a while. It also goes up if the lock is faulty. A lock that sometimes works is not a small issue. It is often a warning sign.
If you have moved in late, are dealing with a lost key situation, or have discovered a damaged lock out of hours, this is exactly the sort of problem a mobile emergency locksmith is there to sort quickly at the property.
What affects the cost?
Cost depends on the type of lock, the number of doors, and whether the job is a straightforward cylinder change or a more involved repair. A standard euro cylinder replacement is often simpler than replacing a full multipoint mechanism in a uPVC door. Timber door locks can vary too, depending on the size and security rating needed.
The cheapest option is not always the best one. If a lock is changed for a very basic replacement, you may end up paying again later to improve security or deal with early failure. On the other hand, not every door needs a premium upgrade. Good advice should match the lock to the actual risk and usage.
For landlords and business owners, key control can matter just as much as the physical lock. Having one clear set of keys, knowing exactly who holds them, and resetting access after a tenant or staff change is often worth more than squeezing the price down to the last pound.
DIY or call a locksmith?
If you are confident, changing some cylinders can be a manageable DIY task. But there are a few catches. Measuring the wrong size, buying the wrong type, or fitting it badly can leave the door less secure than before. uPVC doors in particular can be awkward when alignment is already slightly off.
A locksmith is usually the better choice when you are unsure what lock you have, the door is sticking, the key is hard to turn, the property needs several locks sorted at once, or you want the job done properly without trial and error. It is also the safer option if speed matters and you do not want your new home left unsecured while you work it out.
For many customers, the real benefit is peace of mind. A local locksmith can check the condition of the door, identify weak points, change or rekey the lock, and tell you plainly if anything else needs attention.
Extra security changes worth considering after a move
Once the main locks are sorted, it is worth thinking about how you use the property day to day. Some households want keyed-alike locks so fewer keys are needed. Some landlords prefer rekeying between tenancies. Some homeowners choose smart locks on selected doors for convenience, though traditional high-quality locks are still the better fit in plenty of homes.
Window locks, garage access and patio doors are easy to forget, yet they matter. So does lighting and the general condition of doors and frames. Security is rarely about one perfect lock. It is about removing easy opportunities.
If you have taken over a business premises, the conversation is slightly different. Staff access, stock rooms, rear entrances and shutter keys all need considering. In those cases, changing locks after moving is as much about controlling access as preventing intrusion.
When to stop waiting and book the job
If you have just moved and do not know who else has a key, that is reason enough. If any lock feels worn, sticks, grinds, or looks damaged, treat it as a priority. If there has been a break-in, attempted entry or lost key issue connected to the property, do it immediately.
