Frequently Asked Questions

Q: What size door is this Euro cylinder barrel lock compatible with?

A: This Euro cylinder barrel door lock measures 70mm (approximately 2.75 inches) end to end. It is designed to fit standard Euro profile door lock cases commonly found in interior doors. Please measure your existing cylinder before ordering to ensure compatibility. Note: for thumb turn versions, the measurement is taken without the thumb turn knob.

Q: What is the difference between the key turn and thumb turn options?

A: A key turn cylinder requires a key on both sides of the door, making it ideal for external-access doors. A thumb turn cylinder features a rotating knob on the interior side, allowing you to lock and unlock the door from the inside without a key — perfect for bathrooms, bedrooms, and other interior rooms where quick access is important.

Q: How many keys come with this door lock, and are all cylinders keyed alike?

A: Each Euro cylinder barrel door lock comes with 3 keys. All locks in this range are keyed alike, which means if you purchase multiple cylinders, a single key can operate all of them — ideal for simplifying access across multiple interior doors in your home or office.

Q: Is this Euro cylinder lock easy to install?

A: Yes! This lock is designed for quick and straightforward installation. It replaces or fits into standard Euro profile cylinders in minutes using the included fixing screw. No specialist tools or locksmith experience is required.
