Steps
Open the door and check the mechanism brand and model. Look for a name or code stamped on the metal strip along the door edge.
Measure the door and note the handle height, backset and faceplate size. Write these down so you buy a matching KFV mechanism.
Remove the handle screws on both sides of the door. Pull the handles off and take out the square spindle.
Undo the screws holding the mechanism faceplate along the door edge. Support the door with a helper so it does not drop.
Slide the old mechanism out of the door. Keep the screws and any packers in a pot so you do not lose them.
Slide the new KFV mechanism into the door channel. Line up the handle hole and screw holes with the door.
Fix the faceplate screws back along the door edge. Check the mechanism moves freely by turning the spindle with a handle.
Fit the new handles with the spindle through the door. Screw both sides tight but do not overtighten.
Close the door and test the lock, latch and handles. Adjust the keeps on the frame if the door does not close smoothly.
Tips and common mistakes
Take photos before you remove anything so you know how it all goes back.
Buy the exact KFV model, as sizes and screw positions vary between mechanisms.
Do not force the mechanism if it sticks, as this can bend the door or strip the screws.
Ask a helper to hold the door while you remove the mechanism so it does not fall.
Questions
Do I need a locksmith to replace a KFV mechanism?
Not always. If you can match the exact mechanism and use a screwdriver, you can do it yourself. Call a locksmith if the door is misaligned or the new part does not fit.
How do I know which KFV mechanism to buy?
Check the brand and code on the metal strip on the door edge. Measure the handle height, backset and faceplate length, then match these to the replacement.
Can I reuse the old handles?
Yes, if they are in good condition and fit the new spindle. Many people fit new handles at the same time for a fresh look.
