See section below on other notes concerning Xiaomi locks and purchasing one.
Buying and Installation Caveats:
​
  1. Narrow Xiaomi Aqara S2 Body width: The Xiaomi Aqara S2 digital lock body is narrower than most locks. It may not cover the holes left behind by other locks/installers. If your HDB door lock is a BTO lock type with thin body, it should be OK.

  2. Lock backset at 60mm: Xiaomi lock usually comes with 60mm backset. Your existing lock may be 70mm. There may (or may not) be a gap appearing the side of the Xiaomi lock that we can putty.
    ​
  3. Multi-Lock hooks mortise: The Xiaomi Aqara S2 and Xiaomi Mijia mortise has "hooks" for multi lock configuration - something typical in China metal doors but not for Singapore. If they cannot provide mortise without hooks, we will have to cut off the hooks (see picture).

  4. Wrong mortise / screws / shafts for the door width: Be doubly diligent with the door width and suitable mortise (size) and corresponding screws and shafts. Double check what the seller says , double check when you have received them. If you don't do this checks, then China locks and sellers are not for you (and we can't help you here, we won't go over to install until you check and get them right).
    ​
  5. Missing items (caution!): There are cases of Xiaomi Aqara S2 digital lock delivered without all the parts required. So do your own due diligence in researching how many parts / small boxes must be ordered and expected.

  6. Don't try installing yourself: And don't ask your contractor either. We have been called so many times to fix an installation gone wrong and the lock being damaged or it cannot be locked at all. We will not fix a wrong installation because it is more work to figure out what was wrong or broken. 

  7. HDB metal door frame (with concrete filled) If your HDB door is single leaf and the HDB door frame is the old school metal with concrete filled inside, it would be a nightmare to cut the metal and break the concrete inside. We will need a lot of extra time and the rate will be higher than for standard installation (wood frame or HDB double leaf door).

  8. Xiaomi Phone App: Most Xiaomi locks requires Xiaomi phone app to manage (some exception are  Xiaomi Aqara).
    Don't buy Xiaomi lock if you are not prepared to research on your own or how to use the Xiaomi phone app.

  9. Door thickness: Ensure the Xiaomi lock options and specifications fits the door thickness. ​Ensure the gate/gate handle is not so near until it bumps into Xiaomi lock handle. Ask yourself/lock seller but not us!
