Replacing a lever door handle is a simple home-improvement project that can instantly refresh your door’s appearance and restore smooth operation. Whether the old handle is damaged, loose, or outdated, installing a new one usually takes only 15–30 minutes with basic tools.
Phillips and flat-head screwdrivers
Allen (hex) key set (2 mm or 3/32″ sizes are common)
Drill (if enlarging or preparing a new hole)
Chisel and hammer (for latch plate recess, if required)
Measuring tape and pencil
Replacement lever handle set (confirm latch and spindle size)
Clean cloth to protect metal finishes
Before removing the old handle, ensure your replacement lever handle matches:
Backset: the distance from the door edge to the center of the handle hole (usually 60 mm or 70 mm).
Door thickness: typically 35–45 mm (1⅜″–1¾″).
Latch type: passage, privacy, or keyed entry.
Handing: left-hand or right-hand (many modern handles are reversible).
Tip: If you’re unsure, bring the old handle or latch body to the hardware store for comparison.
Locate the fixing screws.
If visible, use a screwdriver to remove them.
If the handle has a concealed rosette, gently pry off the decorative cover with a cloth-wrapped screwdriver to reveal the screws underneath.
Loosen the set screw on the lever neck (if present) using an Allen key.
Pull the handles off both sides of the door and slide out the spindle (square connecting bar).
Remove the latch assembly by unscrewing the two small screws on the door edge and pulling the latch body out.
Keep all old hardware and screws together until you confirm the new handle fits correctly.
Clean the area: remove dirt, paint, or old adhesive that might prevent the new latch plate from sitting flush.
Check hole alignment: enlarge or reposition holes if your new hardware requires a different configuration.
Ensure smooth operation: test-fit the latch and spindle before full installation.
Insert the new latch mechanism into the door edge with the beveled side of the latch bolt facing the door jamb (this ensures the door closes smoothly).
Trace the latch plate outline and chisel a shallow recess so the faceplate sits flush.
Secure the latch using the provided screws.
Test that the latch retracts easily when turned by hand.
Slide the exterior handle into position, guiding the spindle through the latch hub.
Align any posts or locator pins with the corresponding holes.
Hold the lever steady while you prepare to attach the interior side.
Place the interior handle on the opposite side of the door, aligning the screw holes.
Insert the mounting screws and tighten evenly — don’t overtighten, as this may warp the rosette or restrict lever movement.
For concealed-screw handles, snap or twist the rosette cover back into place.
Tighten the set screw on the lever neck (if applicable).
Close the door gently to mark where the latch bolt meets the frame.
Position the strike plate, trace its outline, and chisel a recess so it sits flush.
Screw the plate in place and test closure — the latch should engage smoothly without resistance.
Turn the lever several times; it should rotate freely and return to the neutral position.
Check that the latch retracts and extends fully.
Ensure both levers are tight and level.
Wipe down all metal surfaces to remove fingerprints.
Maintenance Tip: Tighten set screws every few months in high-traffic areas to prevent wobbling.
| Issue | Likely Cause | Solution |
|---|---|---|
| Handle feels loose | Set screw or mounting screws not tight | Retighten screws with Allen key or screwdriver |
| Door doesn’t latch | Latch installed backward | Remove and flip the latch so the bevel faces jamb |
| Lever stiff or squeaks | Misalignment or debris | Loosen screws slightly, realign, and clean parts |
| Rosette won’t sit flush | Tabs misaligned | Rotate gently until it clicks into position |
Always work on an unlocked door.
For fire-rated or electronic locks, follow the manufacturer’s instructions.
