Unless I misunderstood, on the news tonight, an officer said that BT did not know the couple. But then, in this article, it was stated;
.
They showed the key type that would have been required. If the doctor's keys, were the kind they showed on t.v. tonight, I've used a key like that before. It was a "smart" key. So even if he were a security guard at that building prior to his arrest in 2016, there wouldn't be a code to punch in, of any kind, as they said that the key was needed to get into the building and onto the elevator. OP mentioned that he may have come up behind them, put a gun to their back, and walked right in with them. I think that's a possibility.
Smart keys are not easily duplicated and if lost can be turned off:
Consider:
- To copy a key, one needs to simply take the key to a local hardware store, or even to one of those increasingly common key-making kiosks that dot big box stores across the country.
- To copy a smart credential, one needs a card reader, enough time with the card to scan all of its data, matching card stock and a card writer, far too much work for most nefarious characters.
In fact, most people don't possess the technological know-how to pull off duplicating a smart credential.
Smart keys can also be turned off with a few mouse clicks.
If a resident loses his or her key fob, for example, the property manager can simply look up the resident in the system, locate the fob associated with that resident's record and deactivate it because of the "smart" capabilities, that lost credential has gone from a security vulnerability to an afterthought with just a few clicks of the mouse.
