Most homes have one weak point and several strong ones, and money usually gets spent on the strong ones. This is what changes the odds, roughly in order of value.
Tap to call — fastest way to get someone out to you
If you have a uPVC or composite door with a standard euro cylinder, that is almost certainly the weakest point on the property. It can be snapped in seconds, quietly, with tools that fit in a pocket.
A three-star cylinder is the fix. It is about fifteen minutes of work, it costs less than most people assume, and nothing else available at the same price changes your security as much. Check the face of your current cylinder for a kitemark and stars before assuming you already have one — a lot of doors carry whatever the window installer fitted.

On most UK homes the front door has been upgraded at some point and the back or side door has not. That door is frequently older, less visible from the street, and fitted with a two-lever mortice that does not meet what your insurance specifies.
The same applies to doors with glazed panels beside the lock. If the door can be opened from inside without a key, breaking the glass gets someone in and back out with your things in seconds. A key-operated lock on that door closes the exit route.
Rear gates and alley access count here too. On terraced streets they are the commonest route in, and a bolt that can only be operated from inside the garden costs very little.
A forced door usually fails at the frame rather than the lock. The keep — the metal plate the bolt throws into — is often fixed with short screws into soft timber, and that is what gives way.
London bars and Birmingham bars reinforce the frame on timber doors, and longer screws into the structure behind make a measurable difference for very little cost. On uPVC, reinforced keeps do the same job.
This is unglamorous work that nobody sells because there is little margin in it, which is exactly why it is worth asking for.
Ground floor windows and anything reachable from a flat roof, porch, bin store or garden furniture. Upstairs windows above open ground are a much lower risk and rarely worth spending on.
Key-operated window locks and restrictors are the standard answer. On older uPVC the locks often fail on the same timeline as the door mechanism, so if your door has needed work the windows are likely due as well.
Patio and sliding doors deserve a specific look. They are frequently the oldest lock on the house, the least used, and on some generations of frame the easiest point of entry on the property.
Extra deadbolts on a door whose frame is the weak point. More locks on a strong door do not help when the timber around them is what fails.
Very high-specification cylinders on a door with a glazed panel next to it, where the glass is the route rather than the lock.
A locksmith who recommends work you did not call about should be able to explain what specific weakness it addresses. If the answer is general rather than specific to your door, it is fair to decline. No upgrade is ever a condition of completing the job you actually called for.
Three steps, and you know the price before anyone touches the door.
What has happened, what kind of door, and where you are. You get a likely cost range and an honest arrival estimate — not a best case.
The locksmith looks at the actual lock and confirms the price. If it is more than the estimate, you hear why before work starts, and you can say no.
Door opened or lock fitted, everything tested with you there. Card or cash on completion, with a receipt and warranty.

A three-star anti-snap cylinder on a uPVC or composite door. Nothing else at that price changes your security as much.
Look at the face of the cylinder where the key goes in. A three-star cylinder carries a kitemark and three stars. If there are no markings, assume it is standard.
On ground floor windows and anything reachable from a flat roof, porch or garden furniture, yes. Upstairs windows above open ground are a much lower priority.
Most policies specify BS3621 on final exit doors. Check your policy wording, then check your lock faceplate for the kitemark. The two not matching is a problem at claim time.
No. Upgrades are quoted as an option and never as a condition of completing the callout you rang about.
Different rather than better. The mechanical part still has to meet the standard, and a smart lock on a weak cylinder or a split frame does not address the actual weakness.
Not if the lock allows otherwise. Most standard cylinders and nightlatches can be opened non-destructively. Some high-security locks cannot, and if that is the case you will be told before anything is drilled, along with the cost of the replacement.
It depends on the lock type, the time of day and whether the cylinder survives. You get an estimate range on the phone and a fixed quote at the door. There is no charge if you decide not to go ahead once you have the quote.
It depends on where you are and what is already booked in. You will get a realistic time on the call, and a message if it changes.
Yes, the line is answered 24 hours. Out-of-hours rates are explained on the call, not added afterwards.
Yes, for entry to a property you live in, with proof of residence. Changing locks in a rented property usually needs the landlord's agreement, and we will tell you where that line sits.
Ask for the company name, the locksmith's name and the vehicle before they arrive. You will get a written receipt with the business address on it. If anything about a locksmith feels wrong, do not let them start work.
Yes, card or cash on completion. Payment is taken after the work is finished, not upfront.
No. We do not work on vehicles at all — no car keys, no transponder programming, no key fobs. That needs a specialist auto locksmith with different equipment, and we would rather tell you now than waste your time.
