Button does not respond.Unlocking the entrance door due to electronic lock ed-Lock malfunction

"It does not respond even if I press the PIN code"

According to the contents of the declaration, it seems to be a button-type electronic lock.I wonder if the battery has run out.

When I arrived at the scene, it was "ed-Lock" made by Alpha.The lithium battery was just replaced a few months ago.The old ed-Lock uses a lithium battery pack: CR-P2.The battery will last for several years, so you won't run out of batteries anytime soon.

No sound is heard when operating.Half of the buttons do not respond in horizontal rows.It is thought that the substrate has stopped responding due to corrosion.This is a rare symptom for this model.

Well, unlocking method is completed with normal unlocking.

In this case, the main unit needs to be replaced.It will be the new “ed-Lock PLUS” of the successor model.However, a general mechanical cylinder is easier to operate than an electronic lock, but it depends on the landlord.

It seems to be a 52-year-old property, but it must have corroded due to condensation.It wouldn't be surprising if other rooms had similar symptoms.
