What Comes in a Full Sliding Patio Door Handle Lock Replacement Set?

A full replacement set for a sliding patio door handle lock normally includes five part groups: the interior thumb-turn handle, the exterior pull handle, the mortise lock recessed in the door edge, the tailpiece that links the handles to the lock, and the mounting screws. A Keyed version adds an exterior key cylinder; a Non-Keyed version has no outside key function. Before ordering, confirm two dimensions: 3-15/16″ (100mm) center-to-center handle-hole spacing and 38–70mm (1-1/2″–2-3/4″) door thickness.

The five part groups, and what each one does

1. Interior thumb-turn handle. The inside handle you grip, plus the thumb turn that locks and unlocks the door. On the EASILOK A10 Keyed version, the thumb turn carries a 12mm tolerance sleeve: instead of demanding a perfectly cut tailpiece, the sleeve absorbs up to 12mm of length error — the fix for the most common keyed-handle complaint, a key that turns without locking.

2. Exterior pull handle. The outside grip. On the Keyed version it houses the key cylinder; on the Non-Keyed version it is a plain pull with no key function. Note: “Non-Keyed” does not mean keypad, electronic, or smart lock.

3. Mortise lock. The lock body recessed into the narrow edge of the sliding panel, with a hook that swings out to catch the keeper on the frame. The A10 uses a standard 45° keyway mortise hook lock — a universal type, not a proprietary one.

4. Tailpiece (the operating connection). The flat metal bar that carries motion from the handles to the mortise lock. This is where most replacements fail: legacy tailpieces are short — many max out at 42mm doors — and must be cut to an exact length. EASILOK’s answer differs by version. The Keyed tailpiece is detachable: remove it for standard doors so nothing binds inside the lock, keep it to bridge extra-thick doors, and trim it comfortably on a workbench instead of mid-air. The Non-Keyed version uses an extended-length tailpiece that needs no cutting at all.

5. Mounting screws and instructions. Screws must match the door thickness. A screw set that only covers 1-1/2″–1-3/4″ doors will not work on a 70mm door; a complete kit includes screws for the full 38–70mm range.

Keyed or Non-Keyed: which set do you need?

Choose Keyed when someone must lock or unlock the door with a physical key from outside — a patio, a yard, a rental unit. Choose Non-Keyed when the outside needs only a pull and locking is always controlled from the inside thumb turn. Most patio doors never need an outside key, which is why the Non-Keyed version exists.

The two measurements to take first

1. Handle-hole spacing. Measure from the center of the upper hole to the center of the lower hole: 3-15/16″ (100mm). Measure center to center — not edge to edge, not the handle’s overall length, not the faceplate screws.

2. Door thickness. Measure the structural stile only, without weatherstripping: 38–70mm (1-1/2″–2-3/4″). This range is wider than standard replacement sets, which is why doors up to 70mm thick — stranded by short-tailpiece handles — are covered here.

When a full set makes sense, and when one part is enough

A full set is the practical choice when several connected parts are worn, missing, or mismatched; when you are switching between Keyed and Non-Keyed; or when the old parts can’t be identified. One compatible part may be enough if only the pull is cosmetically damaged while everything else operates, or if you are only missing screws of a known size. Do not replace lock hardware to fix a dragging panel — check the rollers, track, and keeper alignment first; those are door problems, not lock problems.

What this set does not fit

Doors whose handle holes are not 3-15/16″ center to center (for example, Andersen gliding patio doors, which typically use a 5-1/2″ spacing); doors outside the 38–70mm thickness range; hinged or French doors; storm doors; and multipoint locking systems.

Frequently Asked Questions

Does “Non-Keyed” mean it is a smart or keypad lock?
No. Non-Keyed means there is no key cylinder on the outside pull. Locking is controlled from the interior thumb turn. There is no keypad, no electronics, and no battery.

Will the Keyed cylinder work with my existing mortise lock?
Only if the whole path matches: 3-15/16″ hole spacing, 38–70mm door thickness, and a tailpiece that engages the mortise hub without binding. A keyed handle cannot automatically operate every mortise lock.

Do I have to cut the tailpiece to length?
On the Keyed version, no precision cutting: the detachable tailpiece plus the 12mm tolerance sleeve absorbs normal length error. On the Non-Keyed version, no cutting at all — the extended tailpiece fits out of the box.

Is the set reversible for left- and right-sliding doors?
Yes. The design is non-handed and works on panels that close toward either side when assembled per the instructions. Reversible does not mean universal — the hole spacing and door thickness still have to match.

Bottom line

Bottom line: if your sliding patio door has 3-15/16″ handle-hole spacing and a door 38–70mm thick, a complete EASILOK A10 handle lock set replaces the full path — thumb-turn handle, exterior pull, mortise lock, tailpiece and screws — with no precision tailpiece cutting on the Keyed version and zero cutting on the Non-Keyed version.
