FAQ
What type of keyways do these budget locks typically have?+
Budget cylinder sets often feature a 3-pin brass keyway, which is standard and provides adequate security for most domestic doors. However, some may offer simpler, lower-security options with fewer pins.
Are the cylinders suitable for external doors?+
While functional, these budget cylinders aren't specifically designed for external use. The finishes might not withstand prolonged exposure to weather and their security features are generally less robust than those used on exterior doors.
What tools will I need to install a budget mortice lock?+
You’ll typically need a small screwdriver (usually Phillips head), a mallet, and possibly a drill for pilot holes. Ensure you have a level to ensure the lock is fitted squarely within the door frame.
How do I measure my door for a new cylinder?+
Measure the bore diameter – this is the internal diameter of the hole where the cylinder sits. Most UK doors use a 8mm or 10mm bore, but confirm this before ordering to avoid compatibility issues.
What’s the difference between a mortice lock and a euro cylinder?+
A mortice lock fits into a mortise (a recess cut into the door), while a euro cylinder is a cylindrical locking mechanism that requires a hole drilled through the door. Euro cylinders are generally more secure but require a larger installation.
What should I check before purchasing a budget lock set?+
Always verify the dimensions of the lock and cylinder against your existing door frame to ensure a proper fit. Confirm the keyway depth is suitable for your security needs – a deeper keyway provides greater resistance to forced entry.
Are these locks compatible with standard UK doors?+
Yes, these budget sets are designed to be compatible with most standard UK front and back doors, which typically use a 8mm or 10mm bore for the cylinder.
What security level would you describe these locks as?+
These budget cylinders offer basic security suitable for deterring opportunistic crime. However, they are not designed to withstand determined attacks and shouldn't be relied upon for high-security applications.
How do I know if the cylinder key is turning smoothly?+
A smooth turn indicates proper lubrication. If the key feels stiff or catches, apply a small amount of graphite lubricant specifically designed for locks to the keyway – this will ensure smooth operation and prevent sticking.
What’s included in a standard budget cylinder set?+
Typically, a budget cylinder set includes the cylinder itself, a spindle (the part that connects the cylinder to the lock), a beading strip, and sometimes a small amount of lubricant. Always check the product description for complete details.
