To make your front door more secure, fit a TS007 3-star anti-snap cylinder, add a British Standard BS3621 deadlock, reinforce the frame and hinges, and lock up every time. These upgrades stop the attacks burglars use most on front doors.
If you are wondering how to make front door more secure, the front door is where most break-ins happen, so it is where your security pays off most. The good news is that a secure front door is mostly about the lock and a few sensible reinforcements, not a whole new door. This guide covers the weak points burglars target and the upgrades that actually work.
Why is the front door a weak point?

The front door is a weak point because it is the most common way burglars get in, and many front doors rely on a cheap, snappable cylinder. If you are wondering how to make front door more secure, start by understanding that the Office for National Statistics links around 70% of burglaries to door entry, and the front door is targeted most because a burglar there looks like a resident.
A euro cylinder is the barrel section of the lock that reads the key and drives the multipoint mechanism on a uPVC or composite door. On a basic cylinder, it can be snapped in seconds, which is the single biggest weakness on modern front doors.
Older timber doors have their own weak points: a worn mortice lock, a flimsy frame, or a night latch that can be slipped. Whatever the door, the lock and the frame are where security is won or lost.
What are the most common front-door weak points?

The most common front-door weak points are a cheap euro cylinder, an unlocked door, a weak frame, exposed hinges, and a letterbox that allows fishing. If you want to know how to make front door more secure, each gives a burglar a fast, low-noise way in, and each has a straightforward fix.
| Weak point | Why it is a risk |
| Basic euro cylinder | Can be snapped in seconds on uPVC and composite doors |
| Door left unlocked | Around one in five burglars simply walk in |
| Weak or split frame | A kicked or levered door gives way at the frame |
| Exposed or short hinge screws | The hinge side can be forced |
| Letterbox near the latch | Allows fishing for keys or the thumbturn |
| Protruding cylinder | Sticks out and is easy to grip and snap |
Working through these weak points one by one turns a vulnerable front door into a hard target.
What upgrades actually make a front door more secure?
The upgrades that work are a TS007 3-star anti-snap cylinder, a BS3621 deadlock, frame and hinge reinforcement, and a letterbox guard. Together they defeat snapping, forcing, and fishing, which are the attacks used most on UK front doors.
Focus on these in order of impact:
- Fit an anti-snap cylinder rated to TS007 3-star, or a 1-star cylinder with a 2-star security handle, so the lock cannot be snapped.
- Make sure the cylinder sits flush, not proud, because a protruding barrel is easy to grip.
- Add a mortice deadlock to British Standard BS3621 on a timber door, which most insurers require.
- Reinforce the frame with a London bar or Birmingham bar, and fit longer hinge screws or hinge bolts.
- Fit a letterbox cowl or restrictor if the letterplate is close to the latch, to stop fishing.
- Add a door viewer or video doorbell so you can check callers before opening.
“On the tools, the upgrade that makes the biggest difference is an anti-snap cylinder,” says a Kingdom Locksmith Ltd. “We see snapped cylinders far more than any other forced entry on front doors. Fitting a 3-star cylinder that sits flush takes minutes and closes off the easiest attack.” Choosing insurance-approved locks also keeps your home cover valid.
Which security standards should you look for?
Look for TS007 3-star on euro cylinders, BS3621 on mortice locks, and Sold Secure or Secured by Design approval on the whole door. If you are wondering how to make front door more secure, these marks show the lock or door has passed independent testing against real attack methods.
TS007 is a UK rating for door hardware, where a 3-star cylinder resists snapping, bumping, and drilling on its own. A 1-star cylinder reaches 3-star protection when paired with a 2-star security handle. On timber doors, BS3621 is the British Standard most home insurers name for final exit door locks.
Secured by Design, the police-backed scheme, and Sold Secure, run by the Master Locksmiths Association, both list tested products. Buying to these standards means your front door security is proven, not just marketed.
How much does it cost to secure a front door?

Securing a front door is affordable, especially against the cost of a break-in. An anti-snap cylinder upgrade typically costs from around £80 to £150 fitted, a BS3621 deadlock is similar, and frame reinforcement adds a modest amount on top.
| Upgrade | Typical UK cost (guide) |
| Anti-snap TS007 3-star cylinder, fitted | £80–£150 |
| BS3621 mortice deadlock, fitted | £90–£160 |
| Frame reinforcement bar | £40–£100 plus labour |
| Letterbox guard or cowl | £15–£40 |
| Locksmith labour, standard hours | £65–£96 per hour |
These are guide prices and vary by door type, location, and time of day, so ask your locksmith to confirm before work starts. Set against the disruption and loss of a burglary, a secure front door is money well spent.
Frequently asked questions
What is the most secure lock for a front door?
On a uPVC or composite door, a TS007 3-star anti-snap euro cylinder is the most secure choice. On a timber door, a BS3621 5-lever mortice deadlock. Pairing a good lock with a reinforced frame gives the best protection.
How do I stop my front door being kicked in?
Reinforce the frame with a London or Birmingham bar, fit hinge bolts or longer screws, and use a multipoint lock or a deadlock. Spreading the force across the frame stops a door giving way at the weakest point.
Are anti-snap locks worth it?
Yes. Lock snapping is one of the most common ways burglars beat uPVC front doors, and it takes seconds on a cheap cylinder. A TS007 3-star anti-snap cylinder stops it and is inexpensive to fit.
Does a stronger front door lower my insurance?
It can help. Many insurers require BS3621 locks on final exit doors, and fitting approved locks keeps your cover valid. Check your policy wording, as requirements vary between insurers.
Can a locksmith upgrade my front door security?
Yes. A locksmith can fit anti-snap cylinders, BS3621 deadlocks, reinforcement bars, and hinge bolts, and advise which standards your door needs. It is usually a quick, same-visit job.
