This is a great lock and easy to install. Had to call tech support to program it though. The setup instructions have been rewritten and  supplemental instructions provided, however, they still don't make it clear you have less than 3 seconds to plug in the battery and push a button to set it or it doesn't work. Tech support was easy to reach and he knew exactly what the problem was which made moving forward fairly easy.
We have several of these in our business to control access. Very heavy duty. We use them outdoors and make sure we by the &#34;-WP&#34; model which is weatherproof. Very durable and the batteries last a long time between changes, generally 1 year or more.
The exterior door to our condo building was jacked by someone who took a pipe and inserted it into the old door lever. We decided to replace it with a keyed entry device. This model was highly rated in all the reviews. What sealed the deal was it came with a very strong recommendation from our locksmith.I can't comment on the installation as we paid the locksmith to do it. He only charged $40 so it couldn't have been too difficult considering we're in the heart of San Francisco.
One other feature is that the exterior handle does not engage until the correct code is entered which means the same crooks who broke in last time will have to find a new trick.
My locksmith recommended this brand. he uses it at the Fraternities , so it is pretty tough. But he would charge more like $700 for the lock I can get online for $400.
Answer: no
