Internal security door, battery powered, changing battery made no

For some people would work normally and others would repeat 30 or 40
times and still no delatching, so invalidly locked out.
Normal proceedure is enter 4 digit code , blue light, turn handle and
enter. If red back-light to the keypad then wrong number entered.
What might be the problem, each of 30 attempts session say, blue light
each time and a slight click of a relay or maybe a solenoid , but no
mechanical delatching. Never a buzz sound of say a current limited bad
contact to the solenoid , not fully energised coil and oscillation
effect. Of course try holding the handle down, not holding handle,
forcing handle up/down.sideways, pulling/pushing door makes no difference.




I would first confirm that the solenoid was working properly by
seperately powering it.
