Does anybody make door knobs that allow exit yet remain locked?
Posted 19 June 2009 - 12:28 PM
I just purchased an Elk M1K kit and my goal is to ensure that all house exits are locked when the system is secured at night. I plan to add electric door strikes and hopefully (fingers crossed that they are compatible) weigand proximity readers with built in keypads (in case somebody forgets or looses their fob). With a door handle that allows exit while remaining locked, the keypad will get us back into the house easily but ensure that the house is always locked.
Does anybody know of door handles that allow you to open the door, yet always remain locked (auto-lock)?
Or, should I be looking at this from a different angle? I thought about electric deadbolts but I wouldn't want an exit blocked if the power was out and they were engaged. I looked for some that were hardwired but couldn't find any with a manual override.
Thank you for any answers/help/guidance.

Unless I'm missing something, all door handles remain locked if you exit.

However, an always locked door knob that you can turn to open from inside even though it is locked on the outside would remove the need to buy additional request to exit sensors. But, if they don't exist, the request to exit may be the only option.

If I understand you correctly, you want a mechanical lock that has to have the key to open it from the outside and can always be opened without the key from the inside. If so, what you need is a classroom lock configuration. Not sure they are the look you are looking for. Might try calling a local locksmith or locksmith supply house, too, for more residential "looking" options.

The deadbolt requires a manual turn of the lock after code entry, so you couldn't do it with that one. But, you should not be relying upon just the bottom door handle to keep your door locked, one light kick and the door is open. The deadbolt and the proper anchors into the inside door frame will make this much more difficult for a bad guy, and while he's repeatedly kicking the door, your alarm will be going off and he will lose valuable time. Less chance of a smash and grab.

You will have free egress from inside.

Just in case anybody ever needs the same, I found many knobs at Lowes and Home Depot that did this!
Yeah, I think most of the newer residential locks have this feature. Most people add an extra deadbolt to one of those handle/locks just for extra security. Without the deadbolt I think it's easier to kick the door in

Garage door access keypad may be another consideration.

I run the door strike off of a battery backup to avoid power outage issues. I have the strike in a fail safe configuration and just keep the door knob locked at all times. We also keep a lockbox with a spare key outside for disasters.
We still use the normal locking door knob instead of getting a special knob. We added a 'request to exit' motion detector inside that unlocks the door if you approach it from the inside. We mounted an ELK-M1KPAS (the decora sized keypad) on the garage side. The garage door uses its own keypad access system.
A few items that we learned:
1. Most, but not all, electronic strike plates are "no load". This means they will not unlock if you have any pressure on them. Even the pressure exerted by the foam gaskets around the door were enough to affect operation of our strike plate.
2. Request to exit button vs motion detector. Our back door is a busy place. There are several doors in close proximity. The back door and laundry room are especially awkward. We have found that the back door and laundry room are too close to prevent accidentally triggering the electronic strike. This issue does not affect proper operation, but when you enter and leave the laundry we often hear the heavy thud of the strike plate engaging and re-locking. Every house is different, but if we had it all to do over again, I think I would have put in a big red 'request-to-exit' button instead of the motion detector.
We like it so much we are planning to add one to the front door as well.

Do you have your garage door being monitored through your security system? I am curious, do I have to get in the habit of opening the garage door first, then arming the system or can I program an ELK to ignore garage door opening for 10/15 minutes after arming?

This is the "Push to Exit" green button we use at work to get out of our server room that has maglocks if we forget to badge in. Works well. There are variations of the same thing
