Question: how would you put in a pin if there isn't any numbers on it ? and there isn't a key part so how do you use a key ?
Document: Put handle back over the key and open door (It will not fit perfectly but it will be sufficient to engage the mechanism and open the door).4. You can now rotate key back 180, remove, reinstall handle.I did not buy mine from amazon but  unless yours was DOA, I don't see how it should perform any different than mine.I hope this helps.
Great door lock and it is so fast at recognizing your finger print. Ive had it on my office door for 3 months now and use it several times a day and its perfect. My only complaint would be the installation, not for an average joe, but not to bad.
I've been using this for half a year now on an interior door from garage to living room and it's been working great. Read other reviews here if you have trouble with installation or programming. My emergency mechanical keys work fine. For those who claim they don't work, here it is how you're supposed to operate the lock with the key:1. Remove handle after removing pin with the provided wrench.2. Insert key and rotate 180 degrees.
I purchased this lock for an office door. I recently had money taken from a coat pocket in the office and decided I needed to consistently keep the door locked. Ordered the Trinity 788. Install went fine. Fingerprint recognition went great also. (which is why it gets two stars). Final step was to confirm the manual emergency latch release (keyed) worked. It did not. Key would turn but latch would not move. Another reviewer here noted same problem.
I wanted a new door handle and a new lock simultaneously so I igured I'd kill two birds with one stone. This biometric scanner is spot on, extremely easy to use and offers three different modes of access: fingerprint, security code, or key. You can also program it so that each individual has a unique ID number so you know who the last one to use it was.
We have purchased several of this lock to use at our retail locations. They work wonderfully with one exception. We relocated one of our stores, and when I removed the functional lock then tried to re-install at our new location, the lock stopped functioning.If you will be moving the lock, you may as well buy multiple ones. They work fantastic provided you install it once and leave it where you initially put it.
The emergency key does not unlock the lock. It turn 180 fine but just not retract the latch when the level was turn. Not a good or safe or reliable product. No support or any website troubleshooting help.
Follow the instructions and you will be up and running in less than a half hour if you have some basic tools.The manual override key is a great back up for when the batteries run out. The handle switches sides very easy as well.Great product so far
If you live in an apartment complex thats not exposed directly to the weather then it would work fine there too. Well I hope this review has help some of you in installing your new Trinity 788 and avoid some of the mistake I made while installing it.Thanks,Nicholas
We took the latch back off and I noticed that my dad had bent the latch hole for the bar that slides thought it so we had to order a replacement one of those but in the mean time it did work but the door would only open by turning the knob on the upswing, when in fact it should turn on both upswing and down swing.
Answer: The keypad is the four buttons on the right. You can create a combo using those. The key part is under the handle. The handle is held on with a tiny hex screw on the bottom. You remove the handle and use the key to turn the lock. A bit difficult to open that way but doable.
