The best value upgrades are the cheap, boring ones: anti-snap cylinders on external doors, a healthy door mechanism, a locked side gate, and good lighting. Expensive gadgets matter far less than getting the basics right. Spend on the lock that stops the most common attack before you spend on anything clever.
Search "home security" and you will be sold cameras, alarms, smart everything. Some of it is genuinely useful, but a lot of money gets spent on the wrong things while a snappable front-door cylinder sits ignored. Here is how a locksmith would prioritise a limited budget.
Spend here first
- Anti-snap cylinders on external doors. The best value upgrade there is. It defeats the most common forced-entry method for a modest, one-off cost. Start with the back door.
- A sound door mechanism. If your uPVC door is dropped, stiff or has a floppy handle, fixing it is cheap and removes an easy weakness. A door that locks properly is a barrier; one that does not is a gap.
- A locked side gate. Denying access to the unseen rear of the house is one of the cheapest, most effective deterrents going.
- Lighting and visibility. A well-lit, overlooked entrance is unappealing to opportunists. Inexpensive and quietly powerful.
Worth it, once the basics are done
- A video doorbell. Good for parcels and a modest deterrent, and reasonably priced now. Useful, but not before your locks are sorted.
- A simple alarm. A visible alarm box adds deterrence. Helpful as a layer, not a substitute for good locks.
Where people overspend
Be wary of pouring money into elaborate gadgetry while the front door still has a basic cylinder. The most over-engineered camera in the world does not stop someone snapping a lock and being inside in under a minute. Smart locks can be excellent, but a smart lock built around a weak cylinder is style over substance. Layer cleverness on top of solid basics, never instead of them.
If you only have a hundred pounds, spend it on the lock that stops the most common attack, not on the gadget that records it happening.
A sensible order of spending
Sort the locks and the mechanism, secure the rear and the side gate, add lighting, then layer on a doorbell or alarm if you want the extra reassurance. Done in that order, a small budget goes a long way. For a tailored view of your home, a locksmith can do a quick security assessment, or read how burglars actually get into Birmingham homes.

Frequently asked questions
What should I buy first on a tight budget?+
Anti-snap cylinders for your external doors, starting with the back door, and any needed mechanism repair. These stop the most common forced entry for the least money.
Are smart locks and cameras a waste of money?+
Not at all, but they should come after the basics. A camera records a break-in; a good cylinder prevents the most common one. Get the locks right first, then add smart devices as extra layers.
Is a visible alarm box worth it on its own?+
It adds deterrence as one layer, but it is not a substitute for secure locks and a sound door. Think of it as a useful extra once the fundamentals are in place.
