See section below on other notes concerning Xiaomi locks and purchasing one.

Buying and Installation Caveats:
​

1. Most Xiaomi locks must use phone App for administration: If you are not the phone app type of person, don't use a Xiaomi lock! 
   
   
2. Xiaomi lock backset at 60mm: Xiaomi lock comes with 60mm backset whereas your existing lock may be 70mm. There are two implications:
   
   a) There may  be a small gap appearing the side of the Xiaomi lock. We can putty that gap. See next related point.The Xiaomi Aqara S2 digital lock body is narrower than most locks. It may not cover the parts of holes left behind. If the HDB door lock is a BTO lock type with thin body, it is OK.
   
   b) Wide body digital lock cannot be installed on single-leaf fire-rated door. (high probability)
   
   
3. Watch the metal gate distance from door: Most Xiaomi locks' handle extends out by at least 80mm (please check again).  It may hit the metal gate (if any). If so you have to leave the gate open.
   ​
4. 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).
   
   
5. Wrong mortise / screws / shafts for the door width: Pay attention to the door width and suitable mortise (size) with corresponding screws and shafts. You are responsible to get this right with the seller (and not us).
   ​
6. Missing items (!): There are cases of missing parts when lock is not delivered. Ask seller for photos of lock parts , mortise, plates, screws and shafts. Do your own research and verify when you receive them.
   
   
7. Don't try installing yourself: And don't ask your contractor either. We have been called many times to fix an installation gone wrong with the lock damaged and the door cannot be locked. It is difficult and time consuming to figure out what was wrong or broken. 
   
   
8. 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).
