As you may have guessed from the title, recent experiences have shaped my opinion about electronic locks.  To date, technicians have come to “fix” the lock 5 times.   It was said by the second technician that the first one 不懂 (doesn’t understand) the lock’s workings -how he’s working as a repairman I’ll never know.  It was said about the second one that he 技术更好(had better skill). I was wondering if they were going to deliberately 卖错 (sell the wrong)  service, only to sell another one at a later time to collect more money.  The 门禁卡 (keycard) was supposed to be very 安全 (safe).  I’d say so, because 我都进不去 (I can’t even get in)!  A thief’s entry would be 不大可能 (highly unlikely).  At any rate, I don’t have time to 闲着 (lounge around) at home all day waiting for repairs, much less 5 times in a row- that is the running tally.  It was getting to the point where I was going to ask the repairpeople to 赔我 (compensate me.   The most I can do for now is get a different locksmith to change the 门锁 (lock) and handle the keycard reader later.
