Consumers have higher requirements for after-sales service of smart lock products. Smart lock enterprises must recognize this point, try to shorten the time of after-sales service, and provide on-site service in time. This is of great significance for improving the reputation of smart lock brands. Establishing after-sales service outlets in different regions, although it can improve the timeliness of response to after-sales service, but the requirements for capital and labor costs are high, many small and medium-sized enterprises can not do so, so many companies will cooperate with local repair masters. Or handed over to the agent to be responsible for after-sales service, there is no uniform, strict standards, and no sound system is formed, which also causes the strange phenomenon that the short-term after-sales service is difficult to make up.
