Keeping your home secure doesn’t have to be complicated. A few good habits and the right hardware can prevent most lock-related problems before they happen.
Here are seven practical locksmith tips every homeowner should know, whether you live in a flat, a terraced house, or a busy shared building.
Upgrade old locks before they cause trouble
Many homes still rely on outdated cylinders, old night latches, or worn multi-point mechanisms. Over time, these locks weaken, making forced entry easier. Upgrading to modern British Standard locks (such as a BS3621 deadlock or a high-security cylinder) instantly increases protection.
Don’t ignore a stiff or grinding lock
A lock that feels tight, hard to turn, or makes a grinding noise never fixes itself. It usually means the internal parts are wearing out or the door has become misaligned. Ignoring the early signs often leads to a full lock failure, usually at the worst possible moment. Getting it checked early is cheaper and avoids an emergency callout.
Avoid cheap cylinders
A weak cylinder is the easiest point for intruders to attack. Modern anti-snap, anti-drill, and anti-bump cylinders offer far better security and last longer. The cost difference is small, but the protection is huge.
Get your door alignment checked yearly
Weather changes, heavy use, and building movement can shift your door out of alignment. When this happens, the latch or multi-point hooks stop lining up properly. A yearly alignment check keeps the locking points working smoothly and prevents lockouts or damaged mechanisms.
Never force a key that doesn’t turn
If a key isn’t turning normally, forcing it risks snapping it inside the lock. Once that happens, the cylinder needs either extraction or replacement. Stop, step back, and investigate the cause—often a small adjustment fixes it without needing a new lock.
Change the locks when you move into a new property
Many people assume previous tenants or owners returned all the keys, but there’s no guarantee. Contractors, cleaners, neighbours, and even estate agents may have had access. Changing the locks immediately after moving is one of the simplest ways to secure your home from day one.
Keep a spare key in a secure place, not under the doormat
Hiding a key outside is an open invitation to trouble. Instead, leave a spare with a trusted neighbour or family member. If you prefer a digital option, a certified key safe mounted in a hidden location is a good alternative.
Final thoughts
Home security doesn’t always require major renovation or expensive equipment. Small maintenance steps, timely upgrades, and a bit of awareness go a long way. With the right habits, you can avoid lockouts, prevent break-ins, and keep your home safe with minimal effort.
