Chosen Solution

Certainly have enjoyed SHS-P718. I do though have an occasional (5-10% exits) issue arise where interior function not allowing one to exit home. I couldn’t determine if some sort of improper closure of door triggers the lock not to function on the next exit activity. When I get home it locks, but will not open from inside anymore. Either way the solution requires keep trying or re-entering from outside generally with bio/keypad. There does not appear to be an interior override to lock from inside. Also couldn’t find any emergencial way to open from inside. Batteries are new. Obliviously, this represents a significant fire hazard that I must resolve.

Couldn’t find a way to fix it. But I noticed that the way you pull the door to open really mathers, I must always open it from the upper part of the latch, and use a second hand to hold the device. If you use just one hand to open without enough strength on inicial pull, the lock system will go into a mid status where it doesn’t back to lock status and can’t go further to unlock status, this is not visible but obviously the door lock stops working… It’s really boring and non pratical, but I’m used now to use both hands to open it.

I hope to shed some light on this by sharing what we know about the issue and solutions that we attempted. Background: We have installed about 3000 of these Samsung locks (P718 and variants of these) since 2015 and we do sometimes get “I am locked inside” calls over the years. Installation experience matters much more so (for this “push-pull” lock from Samsung). versus the traditional turn lever type of digital locks. Issues and solutions Issue #1: Unable to unlock from inside when pulling the handle but manage to unlock after a few times. This is due to installation issue where there is friction between the bolt and the strike (on the door jamb). Temporary solution: push door in with one hand while pulling the Samsung handle. Proper Solution: Adjust the strike plate Issue #2: Unable to unlock from inside when pulling the handle but unable to unlock even after many attempts. We do see cases where the bolt is jammed so even if you have the mechanical keys , you cannot unlock from outside (because the internal bolt mechanism) is jammed up. Solution: get a + screwdriver and remove the rear lock body and plate so that someone from outside can remove the outer body and exposing the mortise. Stick in a ‘-’ screw driver into the slit (where the ‘ice-cream stick’ like shaft was) and apply force to forcibly turn to retract the bolt (note: may require a lot of force). Issue #3: (mystery): We have heard of some users who solved the above problems after replacing the batteries and there are some posts in this thread that mirrors our thinking, that the mortise bolt mechanism went into an ‘in-flight’ state (that prevents even a manual pull to unlock). Cases from this scenarios resolved itself and the problem did not repeat (to our knowledge after). The sensitity to “in-flight” power loss is a mystery (perhaps to the person who designed the mortise.

Hi @carlosam , What time delay have you got for the Door Lock Time Setup Function? If it is the default of 1 second try increasing the time by a second or two and see if it makes a difference, you can always go back to the default of 1 second if it doesn’t This image taken from the user guide for the lock states that the deadbolt jam problem can be prevented by adjusting the time delay. I’m wondering if this may be what is happening with your lock.

Hi @jayeff . It’s not delay issue, since it happens many minutes (maybe hours) after I’ve entered my apartment. It’s like the unlock mechanism is not being triggered. So I have to keep trying pushing in different ways and strengths until it gives any signal of “life”. Once or twice I had to force the open with a knife on the door’s slit where the dead bolt is. For some reason, when closing, the door is able to lock (dead bolt) but the system is not activated, so it’s not able to trigger the unlocking system.

My lock encountered the same issue but only today it can’t be open. I held e bottom of the handle (inside) and open it, voila. Afterwhich I called e support and they mentioned that battery type is very important. Battery MUST be alkaline. After I change the battery, everything works perfectly. I have been using this lock for 1 year plus.

Hello all, I’ve recently purchased and installed an SHSP718. Unfortunately, I had the same issue last night. I couldnt open from the inside after several minutes and attempts. Is there any update on how to sort this issue? On the other hand, this doorlock came with 5 override mechanical keys. However, I couldnt find any slot for these to be used. Nor from the inside or outside. Any input will be very appreciated. Thanks

The door won’t lock when door is closed when i press and hold the sensor while the door is open the door locks .Any advice?

I am encountering a different problem. Whenever i close the door the deadbolt comes out then goes back in while the lock makes a sound. It eventually goes back in and remains open. Because of this issue, my door cannot be locked. Can someone assist please?

The battery seems to be the cause of the problem. My Samsung SHS P718 suffers the same problem every time the battery is low and even after I replace the battery. The original battery of the lock was Alkaline and used for a very long time, about a year, and no issue happened then. But problem began to occur from the time I changed to non-alkaline bateries. Recently I accidentally used alkaline batteries and the problem no longer happened.

i…… stuck in the house, with no batter to change. the door cant open from the inside…. have to call security bring some batteries for me.

I remove the spring bolt and use only the dead bolt problem solved . Been using it about 4 years now

We have issue with p728 which cannot autolock after it got reset . I can auto lick using the key . How to resolve it ?

I have this problem with Samsung Dr708 if I tried to pull the handle too early from the inside before the door opening melody finishes. This unintentional pulling cause the spring bolt to be “pressed” against the strike plate and prevent the door from opening. Just wait for the door opening melody to run about 1 second before trying to pull the handle.

I noticed our SHS-P718 has been doing some strange things over the past couple of weeks, including unable to open from inside and random failure to lock/unlock like it was dead batteries, even though I had just replaced them. I had a good look at it today and thought perhaps the batteries were not contacting properly and the lock was intermittently losing power. I gave all of the battery terminals on the lock a good clean with a bit of fine sandpaper and then stretched the springs slightly with a small screwdriver. Problem solved, the door lock is working great now!

the answer lies in your door width. If your door is to narrow for the spindle, when you tighten the lock together you are putting to much pressure on the mechanism it, that wont work. The spindle turns without needing power from the inside, its purely mechanical. Your solution could be to get a wider door, add a spacer (make sure you add 2, one on the outside and one on the inside, this way both sides are even, or trim your spindle down, which I do not recommend.

I had one incident in 5 years where the whole family was trapped inside. Reason? Earlier changed batteries to Energizer Max. Apparently this battery is “too strong” and affected the electronics. This is what the dealer said. So just use “normal” akaline batteries. And just use 4 (best) or 6 batteries Max. No repeat incident since.

I solved the “unlock from inside” problem like this:

For the latch bolt to make contact before the dead bolt.
