	~~Add~~ to me!		Entire books have been written about impressioning locks, most notably “Keys to the Kingdom: Impressioning, Privilege Escalation, Bumping, and other Key-Based Attacks Against Physical Locks”, by Deviant Ollam. Impressioning is possible because of the pin’s “binding effect” when the core is rotated – the same principle that makes lock picking possible. When impressioning you’ll need to prepare a blank key by lightly sanding flat the top surface with 600 grit sand paper. This grit will leave slight sanding marks on the surface, which is precisely what you want. Insert the prepared key into the lock and turn it back and forth several times. When you remove the key expose the prepared surface to a bright light and you’ll see rub marks, indicating the location each of the pins. Use a six inch, #4 Swiss cut round file to put a small groove at each mark. Make only 2-3 light swipes to locate the pins and leave a slightly textured finish in the grooves. Repeat. At some point only the binding pin will leave a rub mark, that’s what you are looking for. Make 2-3 light swipes with the file only on the binding pin’s location. Repeat. If you see a mark at the same location, give it another couple of swipes with your file – go slow. Repeat. At some point that pin will no longer leave a mark, but ANOTHER pin will. That’s the new binding pin, so give it a couple of swipes with your file. Continue doing this until the lock opens. Congratulations! You have just impressioned your first lock. The biggest mistake noobs make is filing away too much material because they get in a hurry. Once you’ve done that the game is over – and you’ve failed. Be SURE of your marks before filing and take your time. You may not get a mark every time. If that happens simply put the key back in and turn it some more. Try to not be too vigorous with the turning though or the key will weaken and break. If you see that happening, stop and cut a new key to the same depths then continue where you left off. For a LOT more detail on how to do this, check out Impressioning Manual for Amateur Locksmiths.

	Preparing the blank key is meant to enhance the marks left by components. To begin, the blank may be lightly filed to produce a smooth, uniform surface. Care is taken to ensure that filing does not exceed the first depth of the key at any point before the impressioning process begins. The [[Key#~~bitting~~\|bitting]] surface may be filed to a knife edge to thin the bitting material, making it easier to produce impressions.

	After obtaining marks the key is inspected. Visual aids may be used, such as a magnifying glass, colored/UV lights, or a microscope. The marks left will be different based on the technique, lock type, and component <span class="plainlinks">[http://weightlossproductreviews.info/ <span style="color:#000000;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;">slimming reviews</span>] specifics.

	Once a mark is identified it can be cut. If the key specifics are known the key may be cut to the next possible depth. More commonly, a hand file is used to remove material in small <span class="plainlinks">[http://www.hghadvancedreview.info/ <span style="color:#000000;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;">hgh advanced supplement</span>] amounts.

	A key made of or prepared with a pressure-responsive material may be used to automate or aid in the process of manipulation-based impressioning.

	Custom keys are available that replace the bitting surface with soft materials, such as lead.

	Against [[Dimple\|dimple]] locks, various types of tape along with a [[Bumping\|bump]] key are used. The key is cut to the lowest depth positions (potentially lower, depending on tape thickness) and tape placed across the <span class="plainlinks">[http://www.teethwhitenerguide.com/ <span style="color:#000000;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;">teeth whitener reviews</span>] bitting surface. When placed in the lock, torque is applied and the key is gently rocked against the pins. The tape conforms to the position of components as binding <span class="plainlinks">[http://www.clearskinmaxreview.info/ <span style="color:#000000;font-weight:normal; text-decoration:none!important; background:none!important; text-decoration:none;">acne skin products</span>] pushes the tape deeper.

Technically, too much torque is impossible provided the key blank withstands it and can be moved to produce marks.

	During the process of obtaining marks torque must be reset after each sample is taken. Failure to do so may leave components bound in incorrect locations and produce inconsistent markings. While obtaining marks, it is often helpful to perform the technique multiple times before releasing torque.		During the process of obtaining marks torque must be reset after each sample is taken.
