In case of emergency, you may entrust locksmith. In most cases, locksmith is capable of unlock keys without damaging key hole. SHARETECH received 113,852 key trouble requests during Sep. 2017 to Aug. 2018.

 

Among these requests, the most frequent cases were 70,385 requests to unlock keys. Especially, requests of unlock “front door” occupied more than 60% (46,815 cases). Therefore, this report conducts research about lost key and request of unlock key.

 

▼When lost key happens most frequently? Situation of key trouble differs between apartment and house.
First, when is the most frequent time of request to unlock key (the most frequent key trouble cases)?
The below chart shows there exists big difference between apartment and house for time slot to unlock font door.

(Source: Unlock Requests to SHARETECH, during Sep.1, ’17 to Aug. 31, ‘2018)

 

Chart 1 shows that key trouble requests from house have remained at the same level from 9:00-18:00, and afterwards, declined. Meanwhile, requests from apartment have remained at the same level from 9:00-16:00, and peaked at 20:00. Another characteristic of apartment, more than 50 requests are reported at all time zones.

 

Reason of difference of peak time between 2 types of home
The difference of request peak time between apartment and house may be due to the its family composition.

 

Single family shares about 18.4% in house resident. Meanwhile, Single family shares about 55.6% in apartment resident (*2). Many of single family are students and members of society, leaving parent’s home. Especially, 96% of single family under 25 years old reside in apartment (*3).

 

Moreover, ’16 Society fundamental research (Ministry of Public Management, Home Affairs, Posts and Telecommunications) reported that 15 – 24 years old resident’s average coming home hour is 19:52 (*4). This time zone is almost the same as peak time zone of unlock request of single family.

 

Young generation often come home late, due to various reasons such as side-job, drinking party, over-time work. Peak of key trouble in late night may be resulted from late coming home of these students and members of society.

（*4 : Heisei 28FY Society fundamental research (Ministry of Public Management, Home Affairs, Posts and
Telecommunications))

 

Meanwhile, in houses, single family ratio is relatively low. At night, some other family members probably are at home. Even without keys, someone at home will open the door. Hence, key trouble requests of house are about half of those of apartment.
On the other hand, in the daytime, housewife goes out for various reasons such as side-job, taking children outside for play. Housewife may suffer from key trouble at constant rate, without any other family at home.

 

▼More than 70,000 lost key occur annually. Where key troubles occur most frequently?
Successive research is about detail of key trouble. Annual 70,385 key trouble reports are broken down in below chart (by apartment, house, etc.).

Chart 2 shows that key trouble requests from house are around 16,225 cases. Meanwhile, requests from apartment are about twice of 30,293 cases, compared to those from house. Considering that single family dominates in apartment, key trouble request are frequently brought by single family.
Since no other family member opens the door from inside, single family has no other option but employing locksmith.
Also, of the reasons of 10,756 key troubles, 9,533 cases (89%) are lost keys, and the remainder 1,233 cases (11%) are damaged keys. This indicates that lost keys occur every day.

 

In addition, there exist certain key troubles for automobiles and motorcycles. Recently, automobile is frequently locked with smart key left inside automobiles (In-lock case). In such trouble cases, drivers employ locksmith. Moreover, drivers may often request road service (e.g. JAF). Actual key troubles are assumed much more than reported number in chart 2.

The research indicates that key troubles occur most frequently, at “20:00 on Mondays”. Some people may lose keys during in commute to office/school, with less attentiveness just after Saturday/Sunday holidays. Also, 20:00 is often out of service of superintendents of building. Thus, it may contribute to the increase of trouble report.
Meanwhile, overall, trouble requests most frequently occur on Saturdays and Sundays. This may be due to that many people go out on holidays, and lose keys outside.
