Unlocking methods and temporary access
For everyday use, you can choose between a fingerprint, PIN, RFID card and smartphone control. A PIN can be useful when you don’t have your phone to hand, while fingerprint access removes the need to carry a physical key.
The lock also supports temporary access codes. These can be used for a visitor, courier or cleaning service without sharing permanent credentials. Having several unlocking options offers flexibility, but it does not in itself provide multiple independent layers of security.
Door compatibility, materials and design
The ToucA51 Pro is designed for euro-profile doors. It can be used on wooden, interior and entrance doors in homes or commercial premises. However, a euro-profile designation alone does not guarantee compatibility with every door: check the cylinder dimensions and the requirements of your installation before buying.
The construction combines stainless steel and PC plastic. The materials are intended to resist wear and weather exposure, but the available information does not specify a water or dust protection rating. The lock has a silver finish that can be matched with different doors and interiors.
Batteries and button life
The lock is powered by three AAA batteries. The stated 10 to 12 months is an approximate battery life, not a guarantee of maintenance-free operation. The batteries must be replaced when depleted, and actual life may vary with use.
The buttons are designed for approximately 100,000 presses, a useful figure if codes are entered frequently. Before installation, it is also worth checking what to do if the batteries run flat and what emergency access options are available.
The WELOCK ToucA51 Pro offers several ways to access a home or workplace. When choosing it, check that it fits your specific door and plan for battery replacement.
