100 steps to reduce your physical strength. WEST554 new installation

"I can't lock it with a key or from inside."

This is a request for the operation repair of defects of the door lock.When I arrived at the site, there was a towering staircase.

Towering 100 steps.How many round trips!

The target is AlphaALPHA thumb-latch tablets.Certainly, the thumbturn is spinning, the cylinder is spinning, and the deadbolt doesn't work.

If the spring is damaged, it can be managed, but if the spindle block is damaged, the lock case must be replaced.

However, the lock case Alpha 3690 is out of stock.

It seems that there is only one key, and it seems that he wants to consider dimple keys for crime prevention.

There are no compatible cylinders for this model number. Nagasawa's thumb-latch decorative locks are also costly to replace.

The proposal was to install a new imposition auxiliary lock.This is because the balance between cost, crime prevention, and operability is just right.

For the thumb-latch lock, I installed WEST554 bronze to cover the hole with the usual antique blank plate.
