The lock itself functioned fine but the confusing part was setup. Apparently mine arrived setup as a left side opening (standard doors usually open inwards from the right). After 3 hrs of setup, the lock kept trying to go into lock position while already locked. Eventually I read in the forums that you need to reset it holding the lock key while inserting the battery. This did it and eventually got it to work. This should be put in the manual somewhere 4 people went thru the whole instructions and couldnt find this simple fix. Other issue was the rekey didnt work so now none of the keys work. We will have to manually take it our and rekey but thats a pain.
