Burglar Alarm vs Locks Priority | Spend in the Right Order
Alarms react to a break-in. Locks prevent one. Here's why most homes in Seaham are spending their security budget backwards.
The security industry has quietly convinced homeowners to buy the reaction before the prevention. A burglar alarm is useful, but it does its job after someone is already inside your home. A decent cylinder lock does its job before they get through the door.
That distinction matters more than most people realise, and it's worth following the money to understand why it gets buried.
Why Alarms Get Sold First
A monitored alarm system carries a monthly subscription. A £35 Avocet ABS or an Ultion cylinder does not. The recurring revenue model means alarm companies have a strong incentive to lead with the alarm, dress it up with smart sensors and app notifications, and let the door hardware be an afterthought. One-off hardware margins are thin. Subscriptions are not.
That's not a conspiracy. It's just commerce. But it does mean the average homeowner in Dawdon or Parkside ends up with a Bell box on the gable end and a standard euro cylinder on the front door that a competent burglar can snap in under thirty seconds.
What Snapping Actually Is
Most uPVC doors in Seaham Harbour, Deneside, and across the SR7 postcodes were fitted with bog-standard euro cylinders at build. These are vulnerable to snap attack: apply lateral force with a pair of mole grips, and the cylinder breaks at its weakest point, exposing the cam mechanism. Door open. Elapsed time: well under a minute. The alarm, if you have one, starts screaming after that minute is gone.
A TS007 3-star cylinder, Ultion or Avocet ABS being the two I'd actually fit, is designed specifically to resist this. Hardened steel clutch mechanisms, anti-drill pins, sacrificial snap points that don't expose the cam. The TS007 test subjects cylinders to 30 Nm of snap force, 100 Nm of drill torque, and pick resistance. That's not a badge, it's a test regime. A £45 to £65 cylinder upgrade is the single highest-return security spend most households can make.
The Sensible Order
| Priority | Spend | Approximate cost | What it does |
|---|---|---|---|
| 1 | TS007 3-star cylinder (front and back) | £45 to £65 per lock, fitted | Stops snap, pick, drill at the door |
| 2 | BS3621 or BS8621 deadlock on timber doors | £80 to £130, fitted | Insurance-grade bolt throw, picks up where the latch fails |
| 3 | Door and frame condition | £0 to £200 | A reinforced strike plate costs £12. A failed frame costs a door |
| 4 | Alarm, monitored or otherwise | £200 to £800+ plus subscription | Alerts, deters opportunists, helps after the fact |
Notice the alarm is last. Not because it's useless, but because an alarm on a door with a standard cylinder is a smoke detector in a house with no fire doors.
The Obvious Objection
Alarms deter. The argument goes that a visible Bell box makes a burglar choose a different street. Fair, and there's evidence for it. But deterrence works on opportunists. A determined, experienced burglar cases the door hardware, not the Bell box. The households most at risk aren't targeted randomly.
One Fair Caveat
If you're a landlord with a Deneside or Eastlea HMO, or a small business on the North Dock estate, an alarm with monitoring does cover scenarios a lock can't, such as a window left unlocked, a rear door, or an out-of-hours intrusion where no one's home to notice. At that point you want both. But you still want the locks sorted first.
Buy prevention before reaction. Fit the cylinder, check the frame, then think about subscriptions.
