ASJ Locksmiths recently attended Shenley Equestrian near Shenley after staff were experiencing ongoing issues with a code lock fitted to a high-security metal door.
Although the lock was functioning, the small turning knob made it extremely difficult to operate due to the weight of the door. This was creating daily frustration for staff and making access far harder than it needed to be.
Alex attended site, assessed the existing installation and recommended a more suitable code lock solution. The existing lock was removed and upgraded to a new model designed to provide improved usability while maintaining security.
Once installed, the new code lock was fully tested to ensure smooth operation and reliable performance. The result was a far more practical solution that made opening and closing the heavy door significantly easier for the team.
This is a perfect example of a lock not necessarily being broken, but simply not being fit for purpose. Upgrading to the correct hardware can dramatically improve day-to-day use while maintaining the security of the property.

To provide maximum protection, we supplied and installed a high-security 3-star anti-snap euro cylinder. These locks are designed to offer enhanced resistance against common methods of attack, including lock snapping, picking, drilling and bumping.

Alex attended the property and carried out a full inspection of the door and locking mechanism. It was quickly established that the thumb turn on the inside of the door was operating correctly, however the key side of the euro cylinder had completely failed and was no longer functioning. Had the fault been left unresolved, the resident could easily have found themselves unable to gain access to their property.
To restore the security and reliability of the door, the faulty euro cylinder was removed and replaced with a new high-quality cylinder. The new lock was professionally fitted and thoroughly tested to ensure smooth operation from both the inside and outside of the property.
The homeowner was left with a fully functioning lock, improved security and complete peace of mind knowing their door could once again be locked and unlocked safely and reliably.
