Dorset's Multi-Point Lock Specialists

If your uPVC or composite door handle is spinning freely, drooping, or feels stiff when lifting, you are likely dealing with a failed internal gearbox. This is the most common vulnerability in modern multi-point locking systems. When this mechanism snaps, the door will either refuse to lock, or worse—jam completely shut.

Many locksmiths will order the part and leave your home unsecured overnight. As a dedicated local Dorset network, our vans are fully stocked with exact replacements for major brands including ERA, Yale, Lockmaster, GU, and Fullex. We specialize in non-destructively opening jammed doors and replacing the central gearbox on the spot, securing your property in a single visit.

First-Time Fix Guarantee

Jammed Shut?
We Stock The Fix.

  • Handle Spinning Freely If the handle turns 360 degrees without engaging the locks, the internal cam has snapped. We replace it instantly.
  • Non-Destructive Opening Even if the door is deadlocked and jammed shut, our technicians can manipulate the multi-point system to open it safely.
  • Fully Stocked Vans We carry a massive inventory of uPVC gearboxes, keeps, and euro-cylinders to secure your home without a second visit.
  • Door Re-Alignment If your door is dropping and causing friction on the locks, we adjust the hinges to prevent future gearbox failure.

"My front door handle suddenly snapped and started spinning, leaving us completely locked out in the cold. Lightning Locksmith arrived swiftly, got the door open with zero damage, and had the exact replacement gearbox in his van. Phenomenal service."

Mechanism Failures

Common uPVC Door Failures.

uPVC and composite doors rely on complex multi-point locking mechanisms. When they fail, forcing the handle will only cause more damage. Here are the most common issues we repair daily across Dorset.

Door Handle Spinning

If your handle turns 360 degrees or droops without engaging the locks, the internal gearbox cam has snapped. We remove the broken unit and install an exact replacement.

Door Jammed Shut

When a multi-point lock fails in the locked position, the door becomes permanently jammed. We use specialist spreader tools to bypass the deadbolts without damaging your frame.

Stiff to Lock or Lift

Having to force the handle up? Your heavy composite door has likely dropped on its hinges. We re-align the door to remove friction before the extra stress snaps the gearbox.

uPVC Door Repair FAQS.

Don't let a rogue trader convince you that you need a brand new door. Here is the honest truth about spinning handles, jammed locks, and first-time fixes across BH postcodes.

My handle is spinning freely. Do I need a whole new door?
Absolutely not. A spinning or drooping handle almost always means the internal gearbox (the central part of the locking strip) has snapped due to wear and tear. We simply remove the broken gearbox and replace it, saving you the hassle and delay of replacing the entire door.
My uPVC door is completely jammed shut. How will you get it open?
Without damaging your frame. When a multi-point lock fails in the locked position, the door becomes permanently jammed. We use specialist spreader tools to carefully flex the uPVC frame and bypass the deadbolts, allowing us to open the door non-destructively so we can repair the mechanism.
Do you carry the right parts, or will you have to order them in?
We aim for a first-time fix. Our Dorset dispatch vans are fully stocked with a massive inventory of gearboxes, mechanisms, and keeps for all major brands (Yale, ERA, Lockmaster, GU, Fullex, etc.). In the vast majority of cases, we complete the repair and secure your home in a single visit.
