Find quick answers to common questions about our locksmith services below. We’ve created this FAQ section to give you clear, accurate information fast—especially when time matters.
Our local locksmiths aim to reach you as quickly as possible, often within 30–60 minutes, depending on your location and traffic conditions.
No, our skilled locksmiths use specialised locksmithing tools and are trained in non-destructive entry techniques to open doors safely and efficiently, ensuring your lock and door remain undamaged.
If your key has snapped inside the lock, avoid forcing it or trying to turn the lock further, as this can push the broken piece deeper and cause more damage. If part of the key is still visible, you may be able to gently remove it using tweezers or needle-nose pliers. Do not use glue, as this can permanently damage the lock.
If the key is fully lodged inside or you’re unable to remove it safely, it’s best to contact a professional locksmith. In most cases, the broken key can be extracted quickly without needing to replace the entire lock.
Typically, we can provide a fixed price over the phone in advance. This approach ensures transparent pricing, so customers are fully aware of the cost before work begins. Our pricing is based on the job rather than an hourly rate. For issues like a failed multipoint locking mechanism, we offer an estimated price range from the best to worst-case scenario, as identifying the exact fault requires an on-site inspection.
If your door isn’t locking properly, it may be caused by alignment issues, a defective lock mechanism, or movement in the door or frame due to weather changes and everyday wear and tear. You might notice the key turning without actually locking, the locking points failing to align with the strike plates, or the lock feeling tight or difficult to operate.
Begin by inspecting for basic issues, such as loose screws, or try operating the lock with the door open. Avoid forcing the key or handle, as this can worsen the problem. If the issue persists, a professional locksmith can evaluate the lock and repair or replace any worn or damaged parts to ensure your door functions smoothly and securely.
