Keyless entry is when someone doesn't need a traditional key to open a door, instead the key is replaced with a number pad and/or electronic sensor and some kind of RFID tag.

The "Key" Problem

At the Salt Lake City Bicycle Collective we had a proliferation of keys to our shop, mostly legitimate, some not. This was mainly the result of not having a solidified volunteer structure and a laxed key policy for who had access to the shop. The issue was that every time a volunteer would copy, lose, move, or go MIA -- there would be an unaccounted master key to our shop floating around.

Possible Solutions

Re-key the Door

To re-key the door and provide copies to all the legitimate people on the key list would cost around $100 and $3 per key. We could do this, but then we didn't want to do it again.

Re-key the Door with a Special Key

Most Locksmith shops have a proprietary system that in theory only they can make copies of. They keep a list of authorized people from your organization, so when someone comes to make a copy, they have to present photo ID before they get a copy. This was around $200 and $7 per key. However we still would have to deal with the lost key problem.

Number Pad Keyless Entry

We considered using a number pad, but in today's world of fast cell phone texting that didn't seem like a good idea at all.

Smart Key (RFID) Entry

This uses a card reader that smart cards (passive RFID) that look like thick credit cards and/or keychains are waved by. The downside is that it is by far the most technical, expensive and complex of all the solutions. On average outfitting a single door was around $2,500 -- luckily we were able to get almost everything donated.

  1. A log is kept which holds people accountable for using the shop off hours.
  2. RFID cards are granted and denied access, so if someone loses a card -- we just disable that card.
  3. We have the ability to grant limited access -- so someone can only open the door for an hour on a given day.
  4. Web based control.

Installation Tips

  • Since we are using the PowerDSine, we don't need to use the external power supply to the PCON.
  • The system is 12v, so the HES 5000 Series Strike does not need to be rewired (page 5).
