    We love our new keyless locks. I ordered three keyless locks’ having no idea of what I was doing. The website instructions were clear and easy to understand regarding which type of lock and the right hand or left hand determination. The locks were delivered to me promptly’ and the instructions included made installation simple and problem free. We love the convenience of having security without having to carry keys around with us all day.

    These L1000 locks replace 25-year-old 1000 (non-lever) locks that have given 100% trouble-free service in a hot’ dusty’ (occasionally) wet outdoor environment in Las Vegas. These locks are on the pedestrian gates controlling 24-hour access to our small gated community. We are only changing the locks because many of our residents are now advancing in age’ and were finding it difficult to turn the plain knobs on the 1000s. Since installation of the L1000s’ our residents are very happy. These look solidly built’ perhaps even moreso than our old 1000 locks that they replaced.

Customer Questions & Answers

  1. Answered by the admin

    This lock requires a code to enter but does not require a code to exit from the inside. 

  2. Answered by the admin

    Yes, this model has a passage mode feature so that the door can be left unlocked if needed.

    No, these are fixed handles and cannot be changed in the field. Please see our handing guide to ensure you choose the correct handing before purchasing. If you have any questions please contact our commercial sales department.

    This lock is not compatible with a panic bar. Kaba does make a lock that is however. Take a look at the Simplex LP1010. You'll want to be sure your panic bar model is on the compatibility list. If not, we have offer the exit bars and can show you a couple of options. Connecting the bar to the lock is straightforward, instructions are provided.
