Lockey 3210 Marine-Grade Heavy-Duty Deadbolt Keypad Lock

The Lockey 3210 Marine-Grade Deadbolt Lock is a heavy-duty outdoor keypad deadbolt lock with a keypad on ONE SIDE ONLY. It has been specifically designed to perform well in saltwater environments. This keyless lock for homes is coated to resist saltwater corrosion and the effects of blowing wind and sand. The special finish closely resembles the color of a Satin Chrome (26D) finish lock. It has a much longer lifetime than a standard finish and provides added strength against the corrosive elements of coastal/saltwater environments.

The 3210 is a keyless deadbolt lock, so it does NOT latch or lock automatically when the door or gate is closed. Instead, you must manually turn the knob on the outside or inside to lock it.

Documentation & Installation

Locking and Unlocking

Unlocking an outdoor keypad lock is quick and easy:

  • On the inside or outside, first press the "C" button or turn the thumb turn as far as it will go. This will clear out any previous keypad entries.
  • Next, enter in the secret code.
  • Finally, turn the knob, lever handle, or thumb turn to retract the deadbolt.

Locking is even easier:

  • Just turn the knob, lever handle, or thumbturn to extend the deadbolt into the locked position. You don't need to enter the code.

The Secret Code

  • All Lockey keyless locks for home are shipped with a random secret code chosen by the factory during the manufacturing process.
  • If you do not want your new lock set to a random factory code, no problem. We can customize your initial secret code for you to whatever you like before your lock is shipped. Once you get it, of course, you can change the code at anytime. This is handy if you are having someone else install it for you when you are not there, as in a vacation home.
  • To have us set up your lock with a custom code, click here to add SVR02-Custom Lock Programming to your Cart.
  • Your secret code can be any combination of letters or numbers that you can see on the keypad except for the "C" key which is used to clear out any previous key presses. Keypads vary depending on the model of the lock, so look at the pictures of the lock you want when choosing a code.
  • Lockey mechanical locks have at least 5 red and at least 10 blue tumblers. This allows for a code that is from 3 to 5 digits or letters long. If you would like fewer or more letters or numbers in your secret code, just add Lockey Replacement Tumblers (Pins) to your cart.
  • Lockey mechanical locks do not support repeating numbers or letters in the code. So, "1234" is a valid code, but "1123" and "1213" are not. This is because the number "1" is used more than once.
