Thank you for your inquiry regarding this item from Prime-Line Products. It is easier to have the original key to open the lock when rekeying your lock with this kit. If you are familiar rekeying locks, you can work to take apart your lock with out a key. Prime-Line cannot assist you with this.

You will not need the pins in the kit for the smart key lock, but you can use the new key to set the smart key lock to open with it but you need the Smart Key little tool and that locks current key to do it yourself. lacking both those, take the Smart Key lock to your HomeDepot store and they should have at least ONE person (may be more a 9-5 type and NOT til 10PM though - ask/plan ahead...). Service was FREE at my local HD store, So you will still have pins to do 5 NORMAL locks. If you are lacking keys for any of the "normal" locks, you can disasemble them as others have posted by carefully removing the thin cover above the springs in the cylinder's pin chambers and dump all current springs and pins out that way, OR remove the rear clip holding the plug in place, and buy some curved shims and an UNCUT KW1 blank and shove the blank into cylinder all the way in and then slide the shim into the very thin gap between the plug and the cylinder body from the rear at the location where the pins are. Be careful since the shim stick is very thin and you can cut yourself easily with it. Best squeeze its flat slightly curved surface between thumb and finger as you shove it gently in, if you don't buy the expensive tool to clamp the shim into. It will STOP when it hits the rear pin that has been shoved way up by the inserted blank key. Now carefully pull the key out slowly and you may have to wiggle the shim in and out a VERY TINY amount as you slowly back that blank out lest it keep the pins from dropping to where that pin chamber's bottom pin is lowered on the ramp at the front of the key to where the shim is at the gap between the top and bottom pin. You can then slide the shim in between those two pins and get it to the next pin chamber and keep doing that until you have all 5 pin chambers with their top pins above the shim and the bottom pin below. The shim being AT the shear line between the plug and the cylinder means that there is NOTHING then left to keep the plug from rotating in the cylinder, so ROTATE it by turning the key perhaps a quarter turn so no shim is still needed to keep the top and bottom pins separated. NOW once you have that picture in mind, realize that as you were backing out the blank key to do the front pin pair, the whole plug could have tried to slide out as you backed the blank key out after shimming the front most pin chamber! DON'T let that happen - it could be a disaster for you. KEEP a finger on the front of the plug and keep in tight in the cylinder and NO you actually need not shove the shim forward for that last front pin chamber but can instead while holding the plug from sliding out the front, instead try rotating the plug as you slowly back the blank key out. Do this in a wiggly trial at rotation as simply twisting hard will bind the pins at some height and not let their gap between them get to the sheer line as the key is being slowly backed out. Once the plug is rotated say a quarter turn, pull the shim out and using the PLUG FOLLOWER in the kit you can now use it to chase the plug out while keeping the top pins and springs in place for use with the new bottom pins you load into the plug to match the new keying. With the new key and pins in the plug, the pins should be flush with its top surface - at the sheer line. With it set that way. you can use the plug to chase the plug follower back out the rear, else you MUST have the plug rotated so its pin chambers will NOT accidentally be under the WRONG cylinder pin chambers which will let the top pins be spring pushed into the wrong plug pin chamber leaving the plug only partially inserted and stuck so it can't go in all the way. Once the plug is in all the way rotate it so its pin chambers are under the cylinders ones and with NO key in there the top pins will drop down locking it correctly in place or with the key in it, hold the plug all the way in as you rotate it to its normal position and then keep holding the plug in as you extract the key. Then install the clip that keeps the plug from sliding in and out. This is actually all quite simple once you get familiar with how the lock works and the steps and options and issues you have.

A smart key lock has a little hole next to the keyhole. No little hole...not a smart lock.
