Room and office doors
Indoor Door Smart Locks for Rooms and Offices
F2 and Z1 serve indoor room and office doors, but they use different lock-body directions and platform configurations.
Start with the existing lock body, then compare the model and app version that can be supplied for that door preparation.
Use the real room, office or apartment door preparation, lock body and app need before choosing F2, Z1, M2 or a nearby mortise route.
Buyer summary
Choose indoor door smart locks by door preparation.
Start from the real door and lock body before comparing functions, App platforms, finishes, or OEM details.
Indoor room and office doors
Choose this category when the project uses interior room, office, apartment, or managed indoor doors rather than exposed outdoor gates or profile frames.
Lock body before platform
Confirm whether the door uses a single latch, 60/70 mm adjustable lock body, or 4585 mortise before comparing App versions.
F2, Z1, and M2 boundaries
F2 and Z1 stay as the main indoor-door choices; M2 is nearby when the preparation is an American-standard lever layout.
Inquiry can start with partial details
A door photo, rough quantity, or short project note is enough to ask. More door evidence simply helps SivoLock shortlist F2, Z1, M2, App platform, and lock-body direction faster.
Fit decision
Confirm whether the door needs F2, Z1, M2, or another category.
The door preparation decides whether the project stays with indoor-door options or moves to American-standard, glass-door, outdoor, or mortise-first decisions.
Room or office wooden door
Choose this path when the project needs a smart lever lock for indoor room, office, apartment, or managed interior doors.
Single-latch or F2 direction
Compare F2 when the door points to a single-latch direction, a larger stainless indoor panel, or 35-55 mm door thickness.
60/70 mm or Z1 direction
Compare Z1 when the door needs a compact lever format with a 60/70 mm adjustable lock body or optional 4585 mortise.
Do not force indoor models onto every door
Compare M2 for American-standard lever preparation, A7 for glass doors, or waterproof categories for exposed outdoor doors.
Product finder
Select the indoor-door lock body and app platform.

Image checkpoints
Check indoor-door photos, door thickness, lock body, backset, mortise, and opening direction.
Photos and measurements decide whether the project should continue with F2, Z1, M2, or a related lock-body category.
Show front and rear panels, door edge, latch, lock body, backset, thickness, handing and finish reference in one review scene.
Front and rear door photos
Show both sides of the actual door so the project team can see panel clearance, handle position, and existing hardware.
Door-edge and lock-body photos
Include the latch, faceplate, lock-body cavity, keeper area, and any existing mortise markings.
Door thickness measurement
Measure the real door thickness and note whether trim, veneer, or decoration changes hardware length.
Backset and center distance
Send a ruler photo or drawing showing the distance from door edge to handle or lock center.
Opening direction and handing
Confirm left or right, inward or outward, single or double leaf, and handle direction.
Finish and sample references
Confirm stainless steel, black, Athens black, or project finish needs before sample approval.
Start the inquiry
Send the indoor-door details you have now.
You do not need every detail to request pricing. A door photo, quantity, or short project note is enough to start; these checkpoints help SivoLock narrow F2, Z1, M2, lock body, App platform, and sample scope faster.
Missing details are okay. Send what is available now and mark unknown items as unsure; SivoLock can review the door direction before final pricing.
Fit, sample and OEM support
Confirm samples, OEM support, and installation documents for indoor-door projects.
After the door direction is clear, confirm model-specific documents, sample behavior, accessory scope, finish, packaging, and OEM needs.
Fit review
SivoLock can review door photos, lock-body evidence, and selected F2, Z1, or M2 direction even when project details are still incomplete.
Sample approval
Sample checks should include panel size, latch or mortise fit, App version, card use, finish, packaging, and accessory scope.
OEM details
Logo, finish, packaging, label, language setup, and project documents can be confirmed after the door direction is clear.
Installation documents
Ask for model-specific drawings, installation notes, and lock-body guidance tied to the selected model and version.

Buyer FAQ
Check common indoor-door smart lock questions.
Check door fit, F2/Z1/M2 boundaries, App platform selection, and pricing questions before or after sending an inquiry.
Which doors belong in the indoor-door smart lock category?
Choose this category for room, office, apartment, and managed interior doors. Final fit still depends on door thickness, lock body, backset, opening direction, and panel clearance.
Should my project choose F2, Z1, or M2?
Compare F2 for a larger indoor stainless panel and latch or 4585 planning. Compare Z1 for a compact indoor lever with 60/70 mm adjustable lock body. Compare M2 when the door uses an American-standard lever preparation.
Can I choose TTLock or Tuya?
F2 and Z1 both have TTLock and Tuya directions, but optional status, Bluetooth or WiFi behavior, and capacity vary by model. Share your preferred platform if the project already has one.
Can I send an inquiry before every detail is ready?
Yes. Send any door photos, quantity, destination, platform preference, or project note you already have. SivoLock can reply with the likely F2, Z1, M2, or related category direction and the remaining checks.
Next step
Request indoor-door smart lock pricing and fit review.
