Does the 3900 have the ability to lock the door when closed or do I have to purchase the separate lock kit to keep my door secure?

My 3900 does not lock the door, I use slide lock that came with the door and turn power off to the 3900 to secure shop.

It does not come with the lock kit. With that said it would still be very difficult to open the door even without the lock kit. The motor does a very good job keeping the door in the commanded position. I did not purchase the lock kit ad fell as if the door is secure regardless.

I see some have mentioned that a lock isn't necessary, but I don't see how the opener would "lock" the door. It simply locks the tension spring, which "assists" in opening the door. The tension bar is connected to cables, which connect to the door. If the tension spring is locked, anyone (or group of people) who is/are strong enough to lift a door without springs, could open the door. Again, this opener doesn't seem to lock the door, but instead locks the tension spring, which is not the same as locking the door.

The lock has to be bought separately. I just bought the 3900 a few weeks ago.

The door is locked in much the same way as a regular door opener. It has a standby rope pull release that will release the door. You should treat it just like any other automatic door opener. If I leave for a long trip, I put a lock on my barn door.

I would recommend that the Liftmaster power door lock be purchased to ensure that the door cannot be forced open and damage the operator

You don't put any lock kit on the opener holds the door closed . If you locked the door and some one tried to operate the opener it would not be good . To secure your door while your gone on vacation or away for an extended time simply un plug it no one can open it . It's a great opener and the easiest opener I have ever installed

I purchased this mailbox because I had some mail stolen. I keep my box locked. However if you don't have a problem with mail thief you can leave it unlocked. The door is fairly snug and will stay closed.

Yes, it comes with hardware for both the pocket door (pictured above with turn lock) and the door frame (hardware plate) . It locks securely.

No it physically blocks the door from opening. Actually someone on the outside could lock you in. Do you have a good deadbolt? The hardest part is drilling the holes, but with the right tools it's doable.

It comes with the keyed lock, therefore no need to buy separately. Good system and will deter the casual passer by. Will not deter the persistent individual.

Hello, the primarily locking mechanism is the insertion of the two sliding pins from above and below. The small key like opening does not have to be engaged to open or lock the mechanism. Hope this helps. Purchased two of these to install and am very happy with the utility if the product.

The power door lock is only for the LiftMaster 8500 side mount operator. It is an additional lock that my managers do not think is really necessary. With any engaged operator, your door is secure and cannot be forced open from the outside. Hope that helps!Ryan M. Entry Systems

There is a catch that catches when you close the gate keeping it closed (you don't have to lock it). To lock it you need the key and you will need the key to unlock it (every time if it's locked).

It locks automatically every time you close the door. It never locks Someone inside the room...unless the handle is turned backwards, of course.

Yes, this lock comes with a small magnetic thing that you can attach to the door frame. That way it can detect if the door is open or closed. If it detects that it's closed, after a few seconds it will activate the deadbolt.

No, code is set independently of the lock. To close, you just close the lid and turn the handle to lock.

There is an extension strap that comes with the kit. It has a little plastic stopper built in. You drape that over the door and then close it. You want to find a sturdy (solid) door to do this on. The hollow ones dont seem to hold up as well. If you are uaing this at home, I recommend getting the wall or ceiling mount. Having the product is worth it! Hope this helps. Josh

Yes, the LS-1500 is a latch type lock so it will automatically latch once the door is shut.

I have these doors. They do indeed lock. I get lots of compliments on the doors and wife feels a bit safer. Reason for the lock is so no one can steal the doors.

Only needs combination from outside. Doors opens normally from inside and once door is shut it is automatically locked.

Yes it comes with one inside security panel that does "latch" into place. There is no key or lock associated with this panel

No it doesn't lock against the existing door. Like a previous customer stated, I too had to use a bar to secure the original door. The seal isn't great either.
