    I enjoy ordering online and the price is better than my previous purchase with a local vendor. Ordering on line is the best thing for busy professionals like myself and thousands of others like me. The lock is a good lock and is just what my Community needs to offer a secure environment that allows others a measure of safety. Thanks & I am glad I found you.

    Product was received in a timely manner as described on the website. Simplex 1011 lock works great and provides security and easy access with a passcode. Lock is heavy duty and of commercial quality. We are using it in a high traffic area and have not had any problems.

    I have used Simplex locks for years and continue to depend on them daily. They are excellent locks especially for high traffic areas.

    The service we received was excellent and the product was exactly what we were looking for. The keyless locks work great. We tried 2 different types of locks that just wouldnt stand up to the use’ even though they were advertised to do so. Your locks are heavy duty and work perfectly.

    To be perfectly honest the installation of the keyless lock is not complete. I was somewhat / very disappointed with the fact that the new lock did not fit into the existing holes in the door. So either the current holes need to be plugged and new holes drilled; or the door needs to be replaced again with new holes being drilled. Plugging the current holes is the most economical approach but the plugs need to be custom crafted another painful exercise.

    I was searching for a keyless entry lock and started to search the internet when I came upon GoKeyless. I toured their website with ease and found that they had a variety of options for my needs. I contacted the customer service rep to purchase the Simplex 1011 lock and found the experience to me smooth and very accurate. A few months later’ I found that I was in need of another keyless entry lock and I immediately went to GoKeyless and purchased the same item which I had purchased prior since I didnt have any issues with the original purchase. Again’ the customer service was outstanding and the shipping was quick. I highly recommend this website and look forward to calling upon them again to purchase my keyless entry locks.

Questions and answers of the customers

  1. Answered by the admin If you have lost your instructions to your lock for programming or installation. Please contact our support team at and they will be more than willing to track down the desired manual and send it to you.

    This specific model does not, however, take a look at the Simplex 1021B, it does have key override.

  3. A

    That is correct, only one combination sequence can be programmed into the lock at any given time. If you have multiple people they would all share that same code for entry. If you would like individuals to have their own unique PIN take a look at the Kaba E-Plex 5000. This is the electronic version of the Simplex 1000 and accommodates multiple user codes.

  4. Answered by the admin

    We do provide a installation service through our network of installers or our internal install team. Please ask your sales rep about the opportunity to have a installation scheduled for your lock. 937-890-2333 option 1

    Yes you can use it with a single hole but without seeing pictures it can be difficult to tell if your setup will work. The lock itself is mechanical so no electricity which means it will work fine exposed to the weather. We do not manufacture gate boxes but we do sell one specifically for this lock that would have to be cut and welded into place of your current gate box as there are no extensions for gate boxes. 

  6. A

    Yes this lock will work with the K-BXSIM Gatebox which you will find in the accessory items listed below your shopping cart at checkout.
