This extra long key is specifically engineered for use with Union 3-lever mortice locks. Featuring an additional 30mm of length on the shank, it is designed to overcome the common issue of standard keys being too short for certain installations.

Typically used in period properties or commercial buildings with exceptionally thick timber doors, this key ensures the user can comfortably operate the lock through the full depth of the door and any additional door furniture. It is compatible with both sashlocks and deadlocks within the Union 3-lever range.

Whether used for a new installation requiring extended reach or as a replacement key for an existing deep-set lock, the precision-manufactured blade ensures smooth interaction with the lock's internal levers. This prevents snagging and extends the operational lifespan of the locking mechanism.

FAQs

This extra long key is specifically designed for use with Union 3 lever mortice locks. It is not suitable for 5 lever locks or other brands.

This key offers an extra 30mm of length compared to a standard Union 3 lever key. This added reach is measured along the shank to help the key pass through thicker door materials.

Extra long keys are typically required for thick doors, such as heavy timber external doors, or when a lock is recessed deeply into the door frame where a standard length key cannot reach the mechanism.

No, this is a key blank. You will need to take it to a local locksmith or key cutter to have it duplicated from your existing Union 3 lever key.
