Yongehurst Lock & Key Co. · Richmond Hill
Access Control Installation: getting ready
Locksmith · Richmond Hill, Ontario

Another employee left and the keys never came back. You changed the locks again, cut copies for everyone who stayed, and paid for a job that repeats itself the next time someone quits, taking a working key out the door with them.
Worth answering before the call
What are the doors and frames made of, as far as you know? Do you expect to add more controlled doors later on? Who in the business will manage the system once it is installed?
How do you decide where the readers and door hardware physically go?
A short walk-through maps which doors get used most, where wiring can run cleanly, and where a reader sits at a comfortable reach for everyone, including anyone using a wheelchair or a cart. Door swing and nearby glass affect where a strike or a magnetic lock sits, and mounting height gets checked against the existing door hardware so nothing interferes with the handle or closer. That walk-through happens before ordering hardware so the layout matches the building rather than the other way around.
What credential types are available: cards, codes, fobs, phones?
A proximity card or fob held near a reader, a code typed on a keypad, or a mobile credential read from a phone are all in common use, and a single building can mix them by door or by person. Cards and fobs are simple to issue and switch off individually; a keypad needs no card to lose but a shared code eventually gets passed around; a mobile credential ties entry to a device the person already carries.
