A Door Gearbox is the most frequently used component of the lock and is, therefore, the most likely to fail. When the central mechanism of a Multipoint Door Lock becomes faulty, it’s crucial to replace it promptly to ensure the lock continues to function properly. Instead of replacing the entire multipoint lock, which can be expensive and time-consuming, replacing the Gearbox is a much cheaper and effective solution. Replacement Door Gearbox is available from MB DIY. Offering many brands such as ERA, Mila, and Lockmaster, which are suitable for uPVC and Composite Doors.
Keep in mind that these items are limited to the lock’s core mechanism. If you are unable to identify the appropriate Gearbox for your door, please contact a member of our sales staff who will gladly assist you.
When searching for a new Door Gearbox, it’s important to consider several key factors to ensure you get the right one. Firstly, the brand is crucial and should be indicated on the metal strip inside the door.
The next factor to consider is the lock size, typically either 35/92 or 45/92. The first measurement, the backset, represents the distance from the front of the lock to the centre of the spindle. The second measurement, the PZ Centre measurement, is the distance between the keyhole and the spindle’s centre.
Finally, the type of spindle is a crucial aspect to keep in mind. If the door handle is positioned identically inside and outside, then the door has a single spindle, which includes a spring to keep the handle in place. On the other hand, if the handle is at different heights inside and out, the door requires a Dual Spindle Gearbox or split spindle gearbox.
Replacing a door gearbox can seem like a daunting task, but with the right tools it is a relatively simple process to complete.
Step 1: Unscrew the door handle from the door. You can use either a screwdriver or a cordless drill to do this.
Step 2: Carefully remove the door cylinder (sometimes known as a barrel) and place it aside. This can be removed by locating a screw which lines up with the door cylinder.
Step 3: Detach the lock strip from the door: Unscrew the Philips screws but leave the Torx screws in place at this point. Removing the Phillips screws will remove the door strip from the door.
Step 4: Once the lock is removed, take out the Torx screws from the Gearbox and make note of the position these screws came out of, then gently remove the gearbox from the bar.
Step 5: Align the new Gearbox with the locking points on the bar and secure it back in place using the screws that were previously removed in the same order.
Step 6: Test the locking mechanism by using both the handle and the cylinder. Ensure the handle engages the locking points and ensure the door cylinder can both lock and unlock the door. Make sure the mechanism is properly aligned before reinstalling it on the door.
Step 7: Reinstall the lock strip onto the door using the Phillips screws and reattach all hardware, including the door handle and cylinder.
You’re all set!
It’s best to always test your new gearbox by repeatedly opening and shutting the door to ensure it is working properly.

While both a uPVC Gearbox replacement and a Composite Door Gearbox Replacement serve the same purpose, the doors are made of different material and composition. uPVC Gearbox replacement is un-plasticized (which is what the letter u represents) and is also known as solid plastic. It is commonly used in the construction of windows and doors. Composite doors, on the other hand, are made from a combination of materials, including wood, fiberglass, and PVC. This combination provides a high level of durability and resistance to weather.
In addition to their security benefits, a uPVC Gearbox replacement is also easily maintained and requires hardly any upkeep. Unlike wooden doors, which can warp, rot, or become damaged over time, uPVC Gearbox replacement is designed to be weather-resistant and require very little maintenance. This can help save time and money, as well as ensure that the door continues to function properly for many years to come.
A door gearbox is a cost-effective and practical solution for enhancing the security of a property. With its durability, resistance to weather, and low maintenance requirements, a door gearbox can provide peace of mind and help to keep intruders out. Whether you are a home or a business owner, a door gearbox is a smart investment that can keep your property secure for many years to come.
Another benefit of replacing a worn-out door gearbox is its ability to enhance the security of a property.
