How to use

Measure the existing cylinder length to confirm the 62 mm (31/31) dimension before purchasing. To replace the cylinder, open the door and remove the fixing screw from the edge of the door that secures the cylinder to the lock case. Insert the supplied key, turn slightly to align the cam, and slide the old cylinder out. Insert the new Top Tools cylinder, align the cam by turning the key as needed, and secure it with the fixing screw. Test the new cylinder with the supplied keys from both sides to ensure smooth operation and correct engagement with the lock mechanism.

Usage recommendations

For best results, confirm door thickness and the backset to ensure the 31/31 split provides even protrusion on both sides of the door. Use the three supplied keys for regular access and keep a spare in a secure location. If higher security is required, consider cylinders with additional security features or consult a professional locksmith for compatible upgrade options.
