Rated 4 out of 5 by from Excellent product This is a very good lock that is well made and works well. Fitting is relatively easy but make sure there is good clearance around the catch as any tightness means the catch gets stuck in and then does not spring back out to lock the door which stays wide open! The slightest sqeeze on the outside of the barrell is enough to make the latch stay in so be warned but once there is a proper 1inch hole it is great!

Rated 5 out of 5 by from Code Lock Excellent quality and easy to install, too soon to comment on reliability but quality of build and materials suggests it will last.

Rated 1 out of 5 by from Disappointment I fitted 2 of these locks, as they look a fantastic product & just right for a public access entrance gate... Sadly, both of the jammed within 6 weeks of occasional use- As there is no sensible way of remedying such a problem or adjusting the lock in any way, I had to abandon the use of this product

How to get it out of code free mode

Have these installed in our toilet facilities and have went in this morning and seems to be in code free mode and can’t get it to release ?? Any suggestions
Asked by: Mike0131
Hi Mike0131 To put the lock into Code Free Access mode first enter the code on the code card followed by the dot passage set button. The lock will now be in Code Free Access mode. To put the lock back to Code Access only press the dot passage set button once followed by the ‘C’ button. Hope this helps

Code free access vs holdback

difference between code free access and holdback facility? Total Depth of the tubular latchbolt? I have 80mm door panel
Asked by: Jonwilton
Hi Jonwilton thanks for the question. Hold back - this is a small snib on the inner handle plate. Open the door and hold the inner handle in the down position and activate the snib and the latch is then 'held-back' giving access to all. As the latch is held back this mean the door or gate will move in the wind. To reverse, just release the snib. Code Free Access - enter the code and press the code free access button. This means the handle will freely operate without the code being entered. As the latch still operates the door/gate can be closed and latched and will not be affected by wind or air pressure. To reverse just press the 'C' clear button. Hope this helps, if you have any doubts please give us an idea of your application and we'll advise you of the best option for you.

Garden wooden door

Hi, Can this lock be used on a external wooden garden door? Will it be ok exposed to all elements?
Asked by: Samh77
Hi Samh77, this lock can be installed outdoors, exposed to the elements, but we do recommend using a silicone based spray to the lock, this will help to dispel dirt/moisture, and maintain the finish. If the lock is being fitted to a gate it is important to ensure the gate closes without slamming, which can impact the latch bolt.
