Install a coded lock.

From simple mechanical "push-button" locks to advanced smart units integrated with your smartphone, choosing the right hardware and ensuring a professional fit is essential. A poorly installed lock not only compromises your security but can also invalidate your home insurance or breach fire safety regulations.

What Does the Work Involve?

• Site Assessment: Evaluating the door material (timber, uPVC, or composite), thickness, and whether it is a fire-rated door.
• Preparation: Removing existing hardware and marking the door for new spindle holes or mortice pockets.
• Structural Modification: Precision drilling or chiselling of the door and frame to house the lock body and strike plate.
• Installation: Mounting the internal and external units, ensuring the spindle is correctly aligned for smooth operation.
• Configuration: Setting up master codes, user codes, and syncing any Bluetooth or Wi-Fi hubs for smart functionality.
• Handover: Testing the locking cycle multiple times and demonstrating the emergency override features to the homeowner.

Typical Costs

Prices vary significantly between basic mechanical units and high-end smart locks that require bridge connections or specialist wiring.

Factors affecting the final price include the door material (uPVC often requires more complex multi-point compatible smart locks) and whether you require a hard-wired power supply rather than batteries.

How Long Does It Take?

• Basic Mechanical Swap: 45 minutes to 1 hour if replacing a similar existing unit.
• Fresh Timber Installation: 1.5 to 2.5 hours to allow for precise chiselling and drilling.
• Smart Lock with Hub Setup: 2 to 3 hours, including app configuration and Wi-Fi testing.
• Fire Door Installation: 3+ hours, as specific intumescent kits must be fitted to maintain the door's integrity.

DIY or Professional?

While a confident DIYer can install a basic mechanical lock on a standard timber door, professional installation is strongly recommended for electronic or smart units. Modern locksmiths ensure that the door’s structural integrity remains intact and that the lock aligns perfectly with the frame. Furthermore, many UK insurance providers require locks to be fitted by a qualified professional to maintain valid cover.

If you are installing a coded lock on a communal entrance or a designated fire door, you must use a professional to ensure the installation meets UK Fire Safety Regulations.

Choosing the Right Tradesperson

• Check Qualifications: Look for a locksmith who is a member of the Master Locksmiths Association (MLA).
• Insurance: Ensure they carry Public Liability Insurance (minimum £1 million).
• Experience: Ask if they have specifically worked with your chosen brand (e.g., Yale, Lockey, or August).
• Red Flags: Avoid "locksmiths" who only offer a drill-and-replace service or refuse to provide a fixed quote.

• "Will this lock meet my home insurance requirements for a final exit door?"
• "Do you provide a warranty on both the hardware and your labour?"
• "If the electronics fail, what is the emergency override procedure?"

UK Regulations

• BS EN 1634-1: If fitted to a fire door, the lock must be tested to this standard to ensure it doesn't compromise fire resistance.
• BS 8621: This standard covers "keyless egress," ensuring you can always exit the property in an emergency without a key.
• Part P (Building Regs): If the lock is hard-wired into the mains, the electrical work may need to be certified.
• GDPR: For smart locks with cameras or data logging, homeowners should be mindful of privacy laws regarding communal areas.

Common Problems

• Battery Drain: Cheap batteries or poor Wi-Fi signals can cause smart locks to die unexpectedly; always use high-quality lithium batteries.
• Door Misalignment: UK weather causes timber doors to swell and shrink; if the bolt doesn't line up perfectly, the motor may burn out.
• Handing Issues: Many locks are "handed" (left or right). Buying the wrong version can lead to the keypad being upside down or the handle working in reverse.
• Code Security: Failing to change the factory-set master code is a major security risk often overlooked by DIY installers.
