After installing your electric bolt lock, after a period of use, the bolt will suddenly stretch and shrink, how can I solve it?
Hello! Thank you for using our company's products. Electric bolt locks are easily magnetized in an electromagnetic field environment and produce residual magnetism, the longer the time, the greater the accumulation, and the smaller the magnetic force, therefore, the electric bolt lock moves more and more slowly, and finally does not move or the bolt cannot be retracted. If the bolt is weak, the bolt will retract automatically. Please check the voltage, the standard voltage used by general products is 12V, due to the unstable power quality, it will cause problems such as too long and too small diameter, these will directly cause voltage drop and current reduction, which will affect the normal operation of the lock. Another possibility is that the bolt of the lock is broken, please contact the salesperson to send the lock to the manufacturer for repair.
