Era Vectis gearbox replaced for a customer in Greystones, S11.
Their existing lock had broken and jammed the door locked on their garden room door.
These mortice-style Vectis locks were invented as an alternative to a traditional euro cylinder lock, meaning they couldn’t be snapped or bumped by potential burglars.
New gearbox installed, mechanism serviced, and striker plates/hinges adjusted to realign the door and get it working 100% again.

One of the most common faults we get called out to is a failed Ultion cylinder. The key becomes stiff to operate, and in some cases, when the key is removed, it pulls half of the plug out of the lock! This is usually caused by the lock never having been lubricated since installation. It’s very important to only use a dry lubricant, such as powdered graphite, to keep them working smoothly.
New APECs AP 3* diamond grade cylinder fitted, complete with 5 new keys and 10 year warranty.

Not sure what has caused the most damage this weekend….. Storm Boelo or “the 49’ers” 😬💨🍃🌬️
We were called out last night to fit an additional lock to a student residence, to enable them to lock their door, after they’d called out a National company to gain entry after the NFP electronic lock failed.
Not only did they damage the entire lock unit, they managed to snap the Master Key off in the cylinder too. After taking over 3 hours to get the door open, they left site leaving a trail of destruction behind, and a door that they couldn’t lock!
New euro deadlock case, key/turn cylinder and cover plates, to comply with fire regulations for keyless exit in case of fire/emergency.
Don’t get caught out by rogue national companies that hide in the Google sponsored listings.
We are specialists in non-destructive entry techniques for all kinds of locks.

National Home Security Month (NHSM) is an annual UK awareness campaign held every October. First launched in 2013, it educates homeowners on property protection ahead of the winter months, when darker evenings and the changing clocks trigger a seasonal rise in burglaries.

Campaign Focus and Goals

• Timing: Runs for all 31 days of October, timed to prepare properties before dark winter nights and the peak of burglary claims around Bonfire Night.
• Weekly Themes: The campaign splits the month into four distinct areas—usually covering doors and windows, locks, smart tech/alarms, and general outdoor security.
• Key Partners: Supported by security brands like Yale and ABUS, as well as police-backed initiatives like Secured by Design.

Essential Home Security Tips

• Check Your Locks: Ensure front and back doors use anti-snap high-security cylinders and windows are properly latched.
• Use Timers: Set indoor and outdoor lights on timers to make an empty house look occupied during early dark hours.
• Review Exterior Areas: Keep side gates locked, trim overgrown bushes that hide entry points, and test external security lights or alarms.
You can explore official guides and seasonal advice directly on the National Home Security Month Website.

Don’t get caught out now the dark nights are drawing in. Contact us today and deal direct with Steve on……

Attended a job in Woodseats, S8 to help a customer whose lock had failed on the back door, despite having only been changed less than a year ago by another “locksmith” company.
The lock they had installed was a cheap Versa euro cylinder, which are poorly made and offer very little protection against a forced attack.
When they asked our advice on which type of cylinder to go for to stop this happening again, we recommended and installed the very latest APECS_UK AP 3* anti snap cylinder, backed by……

❌ “49ers” strike in Millhouses ❌
We were called to help a customer in Millhouses, S7 who had sadly been the victim of the dreaded 49ers on Sunday night.
They had just got back home after a long flight, and the locking mechanism had failed on their door. Even though they had the key, the door wouldn’t open.
They believed they were calling a local locksmith, but instead rang a national company who sent out an inexperienced engineer, who struggled for hours to force open the door. They snapped the cylinder lock, drilled off the handles, and mashed up the lock case, but due to the nature of the fault, they still couldn’t get in, without crow-barring the door and forcing it open.
They left the door unsecure, claiming they had no spare parts, leaving the customer vulnerable and with a large bill for their time!
We were recommended by several neighbours on their street WhatsApp group, who we had previously done work for, and arranged to go out ASAP to repair and replace all the damaged parts.
✅New Yale Platinum 2⭐️ security handles
✅Yale Superior 1⭐️ anti snap cylinder
✅ Full length Wink Haus composite door locking mechanism
✅ 2 x new genuine Wink Haus hook striker plates installed.
✅ Door realigned and everything adjusted to getting it working and looking like it did before the 49ers destroyed it!

If you ever find yourself locked out and in a vulnerable position, don’t panic and phone the first number that appears at the top of Google searches.
✅ Always look to check where the company is based…. If there is no contact address, AVOID! 🛑🛑🛑
✅ Always ask for a price…. While it might be difficult to give an exact quote without seeing the door/issue, a genuine locksmith will always be upfront about an hourly rate and give a rough guide to prices of parts that could be required.
✅ Always try to ask for recommendations from street groups/friends who have previously had work done, and save a couple of numbers to your phone…. You may never need to use them, but you’ll be very glad you did in case of an emergency! 🚨
