The keys have been handed over, the removal boxes are in, and there are already ten jobs competing for attention. Security should be near the top of that list. This guide to post move security focuses on the practical work that gives you control of who can enter your new home, identifies weak points early and avoids an unpleasant surprise after moving day.
You cannot know how many copies of a previous key exist, who was given one over the years, or whether an old lock is still performing as it should. Even a property that looks well maintained can have tired cylinders, poorly aligned doors or windows that do not lock correctly. Start with access, then check the condition of the doors and windows protecting it.
Change the locks before you settle in
Changing external door locks is the clearest first step after a purchase. It is not a judgement on the previous owner. Keys may have been shared with family, neighbours, cleaners, tradespeople or former occupants and then forgotten about. A complete lock change means only the people you choose have working keys.
Prioritise the front door, rear door, side access and any attached garage or outbuilding with a direct route into the property. Do not overlook patio doors or a communal entrance where you hold a key or fob. If the property uses the same key across several doors, decide whether you want to retain that convenience through a new suited lock system or give each entrance a separate key.
A professional locksmith can check more than the key operation. They can assess whether the lock type is appropriate for the door, whether it meets the standard expected by your insurer, and whether the fitting itself leaves an avoidable weakness. For many modern external doors, a high-quality anti-snap euro cylinder is a sensible upgrade where compatible. It is designed to resist a common form of forced attack and can be fitted without replacing a sound door.
Keep keys under control from the start. Avoid leaving labelled spares in drawers during the move, and do not hide one outside in an obvious place. Give a spare only to someone you genuinely trust, or use a properly installed key safe where access needs to be managed for family, carers or a landlord.
Check the door, not just the lock
A new cylinder will not solve a door that is dragging, loose in its frame or failing to engage properly. This is particularly common with uPVC and composite doors. What seems like a stiff handle may be a door alignment issue, worn hinges or a developing fault within the multi-point locking mechanism.
Test every external door while it is open and again when it is shut. The handle should lift and return without excessive force, the key should turn smoothly, and the door should close without needing to be pushed, lifted or pulled into position. If you must force it, avoid repeatedly operating it. Continued pressure can damage the gearbox or mechanism and turn a repairable fault into a lockout.
Look closely at the frame too. Loose keeps, failed seals and visible movement around hinges can affect security and weather resistance. Timber doors deserve the same attention: check that the lock, handles, letter plate and hinges are secure, and that there is no rot around the frame or strike area.
A repair is often the right answer. Correctly realigning a door or replacing a faulty uPVC gearbox can restore secure operation without the cost and disruption of replacing the whole door. Doing the job properly means finding the cause of the fault, rather than simply fitting a new part and hoping it holds.
Work through windows and secondary access points
Windows are easily missed during a busy move, especially those in upstairs rooms. Check that each accessible window closes fully, locks with its key and has no damaged handle, loose hinge or gap around the frame. Ground-floor, first-floor extension roofs and side-access windows need particular attention because they may be easier to reach than expected.
Patio, French and bi-fold doors should be tested through their full locking sequence. Check both leaves where applicable, examine the track for dirt or obstruction, and make sure the locking points engage evenly. A stiff sliding door or a handle that only works when lifted in a particular way is worth investigating promptly.
Outbuildings also need a realistic assessment. A basic padlock on a shed may be enough for low-value garden items, but it is unlikely to be suitable for expensive tools, bicycles or stock. The door, hinges and hasp matter as much as the padlock. A strong lock fitted to weak fixings offers limited protection.
Make the property look occupied from the first night
The first few days after moving can leave a property looking unsettled. Curtains may not be up, packaging can build outside and routines are not established. Small measures reduce opportunities without making life more complicated.
Bring post in promptly, keep access routes clear and avoid leaving packaging that advertises valuable purchases outside for days. Set up external lighting where it is useful, particularly around a rear entrance, gate or dark side passage. Lighting should help you see who is approaching and move safely, rather than shining into neighbours’ homes or creating glare.
If you inherit an alarm, smart lock, doorbell camera or access-control system, change app passwords and user permissions as soon as possible. Remove old administrator accounts where you can verify they are no longer needed. Check that alerts go to the right person and that batteries, wiring and backup power are in working order. Technology can be helpful, but it should support sound physical security rather than replace it.
A guide to post move security for tenants and landlords
Tenants should raise damaged locks, insecure windows and doors that do not lock properly with the landlord or managing agent straight away, ideally in writing with clear photographs. Do not assume a sticky door is only an inconvenience. It may be a security issue, and early reporting gives the owner a chance to arrange a repair before the mechanism fails.
Landlords and letting agents need a consistent change-of-tenancy process. Locks should be changed or rekeyed between occupancies, all keys and fobs recorded, and external doors checked for operation before a new tenant arrives. Vacant properties can need prompt boarding-up or re-securing after damage, attempted entry or a failed lock, particularly where access cannot be left unattended overnight.
For managed properties, a master-key arrangement can be useful, but only where key control is carefully planned. It can reduce the number of keys a responsible person carries while preserving individual access for tenants. The trade-off is that a lost master key has wider consequences, so the system needs clear records and sensible restrictions.
Consider how your household will use the property
The best security setup is one people will actually use every day. A complicated locking routine may be unsuitable for a household with children, an older resident or frequent visitors. Equally, leaving a door on the latch because the lock is awkward is not a safe workaround. The right repair or lock upgrade should make secure behaviour straightforward.
Think about who needs access now and who may need it later. A trusted neighbour, cleaner, carer or tradesperson may require planned access. Smart locks and keypad systems can suit some households because codes can be changed without cutting extra keys. They are not automatically the best choice for every door or every user, however. Battery maintenance, compatibility with the door and a reliable physical override all need consideration.
For homes with gates, side passages or shared boundaries, inspect the route a person would take to reach the rear of the property. A secure rear door is less effective if a loose gate gives easy, concealed access. Gate locks, latches and lighting should be proportionate to the layout and the value of what is being protected.
Get faults dealt with before they become urgent
A lock that occasionally sticks rarely improves by itself. If a key is hard to turn, a handle feels loose, a door needs force to lock or you notice signs of attempted damage, arrange an inspection before it fails completely. Emergency work is sometimes unavoidable, but planned repairs give you more time to understand the options and choose the right solution.
