Sparrows Bypass Driver Instructions

Sparrows Adams Rite Bypass Driver

The Adams Rite driver replaces the actions of the Adams rite cam on the back of the cylinder. The Cam rotates on the back of the cylinder when the key is turned.

The important parts to know are the latchbolt, the dead latch and the internal latch.

When the Dead latch is pushed in the latchbolt is blocked from sliding in.

When the Adams rite cam on the back of the cylinder turns it depress the internal latch and pulls it across. The internal latch and the latchbolt are attached so as the cam pulls the internal latch across the latchbolt is also pulled and the door can be opened.

To By-Pass the Adams rite Dead Latch push the driver into the keyway tip down all the way though the cylinder and cam.

Once the Driver is through the keyway and out the cam simply rotate the driver to depress the internal latch and pull it across. This will then also pull in the latchbolt unlocking the door.

Tips & Problems

  1. Some cams have a solid back preventing access to the internals. You can check with a tension wrench to see if you are block.
  2. The Latchbolt can be wedged between the door and the frame putting to much pressure on the internals for the driver to slide the internal latch across (it will be able to push it down allowing it to slide). In this situation use some Sparrows quick shims or a slim Jim to slide the door latch across after the driver has depressed the internal latch.
  3. Putting pressure underneath the latchbolt with a Sparrow Quick Shim or Slim Jim will angle the internal latch in a beneficial way making it even easier for the driver to grab. The 4900 model has a lot of play in this aspect and the internal latch will move quite a bit making it the easiest of the Adams rite models to open.
  4. On some cylinders their can be a very tiny gap between the cylinder and the cam inside the keyway. The tip of the driver might get caught on this lip. You can slide a narrow tension wrench down the keyway to help push the tip out of this gap and all the way through the cylinder. Then just pull out the tension wrench and continue normally.

Sparrows Padlock ByPass Driver

The Padlock ByPass driver is used with the golf head tip facing down.

The special curve in the tip is designed so that the driver will slide though the keyway. The spine of the driver should pass down the center of the keyway.

Push the driver all the way to the very back of the keyway and give the driver a clockwise turn. You will have to use the same amount of force you would to turn a key. If this is unsuccessful try to wiggle the driver to get it into position with very small clockwise and counter clockwise turns about 1/8th of a turn.

When the Sparrows Padlock ByPass driver is in the correct position a turn in the clockwise direction will open the shackle.

What the diver does inside the lock is it goes all the way through the keyway to the inner workings of the lock allowing you to bypass the keyway and open the lock.

Most but not all modern locks will have a security disk that now covers the back of the keyway preventing the bypass drive from entering the inner workings of the lock. This disk can get lost when locks are serviced or rekeyed so it is very possible for the Sparrows Padlock Bypass driver to open modern locks.
