The front door may still be closed, but after a burglary it can stop feeling like a barrier between your family and the outside world. That loss of confidence is entirely understandable. Home security after burglary is not simply about replacing a damaged lock. It is about making the property safe again, preserving evidence, dealing with the immediate practicalities and putting the right protection in place for the future.
The best next step is rarely to buy the most expensive product available. A professional assessment of how entry was gained, how the property is used and what needs protecting will usually lead to better, more proportionate security.
1. Make the property safe before making changes
If you believe an intruder may still be inside, leave the property if it is safe to do so and call 999. If the burglary has already happened, report it to the police as soon as possible. They may need to examine the point of entry, recover evidence or give you a crime reference number for your insurer.
Avoid touching damaged doors, windows, handles or items that may have been moved until the police have advised you that it is safe to do so. Take photographs of visible damage, including broken locks, frames, glazing and gates. These can help with an insurance claim and give a locksmith a useful picture of what needs attention.
Once evidence has been dealt with, secure any vulnerable opening promptly. A temporary boarding repair may be appropriate for broken glass, while a failed lock or damaged door mechanism should be attended to without delay. Do not rely on a chair against the door, a loose padlock or a temporary hasp as an overnight solution.
2. Change locks where keys or access may be compromised
A burglary does not always involve forced entry. Keys may have been taken from the house, stolen from a handbag or car, copied without permission, or used after being lost. If there is any doubt about who has a working key, changing or rekeying the relevant locks is sensible.
Start with external doors, then consider side entrances, patio doors, garages, sheds and gates. Landlords and property managers should also review communal access, plant rooms, meter cupboards and any master key arrangements. A single missing key can create a bigger issue where it opens several areas.
The right solution depends on the existing door and lock type. On a timber door, this may mean replacing a rim cylinder, mortice lock or both. On a uPVC or composite door, the issue may be the euro cylinder, the multipoint locking mechanism, alignment of the door or damage around the keeps in the frame. Replacing only one component without checking the full door can leave an otherwise strong lock operating poorly.
Ask for locks that are suitable for the door, meet current insurance expectations where applicable and are fitted correctly. A high-security cylinder can be worthwhile, but it cannot compensate for a loose frame, weak hinges or a door that does not close into its keeps properly.
3. Identify how entry was gained
A burglary is useful, if unwelcome, evidence about where your home is weakest. The visible damage may not tell the full story. A door that looks intact may have been opened using a snapped, drilled or bypassed cylinder. A window may have been forced because its lock was not engaged, or a rear gate may have given someone privacy and time to work.
A proper security review should look at the route in, but also the route around the property. Consider whether side passages are overlooked, whether rear access is easily reached, and whether tools or ladders have been left outside. Check garages and sheds carefully: they can contain equipment that helps an offender gain entry to the house.
Doors need more than a good lock
For most homes, the front and rear doors deserve priority. Inspect the condition of the frame, hinges, letterbox, glazing and strike plates, as well as the lock itself. If a letterbox allows a hand or tool to reach the internal handle or keys, a letterbox guard or internal cover may be needed.
French doors, sliding patio doors and bifold doors require their own assessment. Their locking points, tracks and handles vary, so a one-size-fits-all answer is rarely appropriate. A locksmith can advise whether adjustment, additional protection or replacement hardware offers the best improvement.
Do not overlook windows, garages and outbuildings
Windows should close fully and lock with the keys removed and kept out of sight. Ground-floor, rear and easily accessible windows deserve particular attention, but an upstairs window above a flat roof, conservatory or extension may also be reachable.
Garages, sheds and garden stores are often treated as separate from the home, yet they may hold bicycles, power tools, vehicle keys and ladders. Fit suitable locking hardware, secure valuable tools where practical and avoid leaving equipment outside that could assist a break-in. A gate is not a substitute for a secure door, but it can make casual access less convenient and more visible.
4. Improve visibility without turning your home into a fortress
Good home security should make an intruder feel exposed while allowing you to live comfortably. Trim back dense shrubs around doors and windows, particularly where they provide cover close to the property. Ensure house numbers can be seen clearly by emergency services and that entrances are not hidden in darkness.
External lighting can help when it is positioned thoughtfully. Lighting at front, side and rear access points is generally more useful than one very bright fitting pointed across the garden. Motion-activated lights can be effective, although they should be adjusted to avoid constant activation from passing pedestrians, pets or trees.
CCTV and video doorbells may provide reassurance and useful footage, but they work best as part of a wider plan. Cameras should cover likely approaches and be maintained, rather than fitted as a token measure. They do not physically stop a door from being forced, so locks, frames and access control remain the foundation.
5. Tighten up key control and everyday habits
After a burglary, it is natural to focus on hardware. Everyday routines matter just as much. Keep keys away from doors, windows and letterboxes, and never leave spare keys under a mat, plant pot or obvious garden feature. If you need to provide access for relatives, carers, cleaners or tradespeople, decide who genuinely needs a key and keep a clear record.
Smart locks can reduce the need to circulate physical keys and can allow access codes or digital permissions to be changed. They are particularly useful for some landlords and busy households, but they need to suit the door, be installed correctly and have a sensible back-up plan for batteries, connectivity and emergency entry.
If vehicle keys were stolen, speak to a vehicle-key specialist promptly. Modern car keys often require programming, and taking action quickly may reduce the risk of the vehicle being targeted from its usual parking place.
6. Check your insurance requirements, but do not delay essential repairs
Contact your insurer and provide the crime reference number, photographs and details of stolen or damaged items. They may have specific requirements around locks, repair invoices and approved contractors. Keep all paperwork, including receipts for emergency repairs and replacement keys.
However, do not leave a property insecure while waiting for an insurer’s decision. Most insurers expect reasonable steps to prevent further loss. A clear record of what was damaged, when it was reported and what emergency work was completed will help demonstrate that you acted responsibly.
7. Choose a qualified locksmith you can verify
Burglary victims are sometimes targeted by misleading advertisements and call centres posing as local locksmiths. Before agreeing to work, ask who will attend, whether they are suitably qualified, what the likely costs are and whether a full security check is included. Be cautious of vague pricing or pressure to replace every lock immediately without an explanation.
A qualified locksmith should be able to explain the cause of the failure or method of entry in plain English, offer options rather than fear-based sales talk, and recommend work that fits the property and budget. Master Locksmiths Association approval provides an additional level of reassurance that the locksmith has been vetted and assessed.
For homeowners and businesses across Aldershot, Hampshire and Surrey, KBO Lock & Safe can secure damaged doors, replace compromised locks and advise on practical improvements without losing sight of what has already been a stressful experience.
A burglary should not force you to live behind excessive security or feel anxious every time you leave the house. With the right repairs, a considered review of weak points and a few sensible changes to access and routines, your home can become a place that feels like yours again.
