Dennis Yeo has been working in the locksmith trade for more than 30 years. His training isn't limited to one tradition either — he's trained in both America and Japan in the art of key and lock manipulation, giving him a broad technical base to draw on. He also brings a background from the carpentry and metal works industry, which feeds directly into how confidently the business handles lock installation, ensuring locks work smoothly once fitted.
The bulk of the work falls into a few clear categories. On the emergency side, that means fast unlocking for people locked out of their homes, offices, or vehicles, along with extraction of keys that have broken off inside a lock. For damaged or spoilt locks, the service covers everything from lockpicking to safe cracking — Dennis describes himself as a well-experienced safe cracker for anyone stuck with a safe or vault that won't open.
On the installation side, 1&1 24Hrs Locksmith changes and installs door locks for both new and existing doors, sets up additional locks where needed, and fits electronic and digital locks, including biometric fingerprint locks and pin-code or tap-card electronic locks. For commercial clients, they also handle custom masterkey systems, which let businesses manage access across multiple doors with a single coordinated key hierarchy.
Automobile owners aren't left out either — the service covers vehicle door and boot/trunk opening for anyone locked out of their car, as well as extraction of broken keys from vehicle locks.
The business quotes quick response times for HDB flats, private residences, and commercial premises alike, which means whether it's a homeowner locked out at midnight or a business needing a new masterkey setup, the same emergency-first approach applies.
