Frequently Asked Questions (FAQ)
Q1: Why choose a thumbturn cylinder over a double-keyed cylinder?
A1: A thumbturn cylinder provides much greater convenience and safety for daily use and emergencies, as you can exit quickly without fumbling for a key. It is the recommended and often legally required choice for doors where a quick escape is necessary (like main exits), provided the door is not fully glazed or has glass panels immediately next to the lock. A double-keyed cylinder (key both sides) is used only when there is a risk of someone breaking glass near the lock to reach the inside mechanism.
Q2: How do I know if 70mm is the correct size for my door?
A2: The 70mm measurement is the total length of the cylinder barrel. To check, remove your current cylinder and measure it from end to end. Also, measure from the door edge to the centre of the handle spindle on both sides. For a symmetrical 70mm cylinder, both these measurements should be approximately 35mm. Always measure your old cylinder or door before purchasing.
Q3: Is the thumbturn side secure from lock picking?
A3: The thumbturn mechanism is on the interior side and does not have a keyway, so it is not vulnerable to picking from the outside. The external keyway incorporates all the high-security features (anti-pick pins, etc.) to protect against external manipulation attempts.
Q4: Can I get this cylinder in a Master Key system?
A4: Yes, most suppliers offer this cylinder type as part of a Master Key or Keyed Alike system. This allows you to have one key that operates multiple different locks (Master Key system) or to have all your locks set to the same key (Keyed Alike) for convenience.
