Yes, and usually without disturbing the access system. Many readers and electric strikes go dark because a power supply, breaker or backup battery has failed, and restoring power reopens the door. Where a mechanical override cylinder is fitted, it opens like any other lock; not every system includes one. An ordinary magnetic lock releases on its own once its power is actually removed, so a genuine power loss opens that door without waiting on a remote release. Afterwards, credentials and schedules are confirmed with whoever manages the system.

Mostly not. A boxed strike sits flush in the jamb, long screws hide behind hinge and strike plates, and a repaired jamb is filled and dressed so paint or stain covers it. A wrap-around door edge reinforcer is the one part that shows, as a slim steel band at the lock, and it can be finished to match the hardware. New deadbolts are matched to the trim on your other doors where you want them to blend in.

Yes, if the cylinders share a keyway or can be fitted with ones that do. Keying everything alike is popular with small shops because staff carry one key and spares are simple. The trade-off is that one key then opens the cash room as readily as the front door. Many businesses choose a middle path: the doors everyone uses on one key, the sensitive rooms on another, and an owner's master that opens both.

It is switched off in the software the moment it is reported, which stops that specific card or fob from working at any door it used to open. A new one is issued and enrolled in its place. No lock has to be changed and no other credential in the building is affected, which is the main advantage a lost fob has over a lost mechanical key.
