Alex attended a property on Morpeth Avenue, Borehamwood WD6 after the homeowner reported that the front door lock had become increasingly difficult to operate. The lock worked intermittently, and lifting the handle to secure the door required more effort each day.
As Alex approached the property, one issue immediately stood out. The existing euro cylinder was protruding significantly beyond the door handles, creating an obvious security concern. However, rather than assuming this was the cause of the customer's complaint, Alex carried out a full diagnosis before recommending any replacement parts.
Based on the symptoms described by the homeowner, his first suspicion was that the door had dropped out of alignment, as this is one of the most common causes of increasing resistance when lifting a handle. The door alignment and multipoint locking mechanism were thoroughly inspected and tested, confirming both were operating correctly.
With alignment ruled out, Alex removed the euro cylinder and tested it independently from the door. The results immediately identified the fault. The cylinder operated smoothly from the inside but became extremely stiff when operated from the outside, confirming that the problem was internal to the cylinder rather than the door or locking mechanism.
The faulty cylinder was replaced with a correctly sized VERSA British Standard 1★ anti-snap euro cylinder. The replacement not only restored smooth and reliable operation but also eliminated the excessive cylinder protrusion, significantly improving the security of the entrance.
Once installed, the new cylinder was thoroughly tested before the homeowner operated the lock themselves to confirm everything was working smoothly.
This job demonstrates why proper diagnosis is so important. Similar symptoms can have completely different causes, and taking the time to systematically rule out each possibility ensures only the failed component is replaced.
