Cathy told me you called and actually need the LK chip, not VLM. I see you purchased the 3880 refillable carts last September. You can get the replacement 3800/3880 reset chip you need here: http://shopping.netsuite.com/s.nl/c.362672/sc.18/category.28306/.f
I am concerned that you may have damaged the printer's LK chip sensor if there was a "clearance issue" and "pins broke off the chip inside the printer"... Can you please clarify which "pins" you're referring to? I am also concerned that the reset chip may have not been properly attached, since there should be no clearance issues if the chips are attached as directed.
Is this the first refill cartridge you'e installed in your 3880? Please remove a neighboring cartridge, then look into the cartridge chambers to examine the chip sensors, which are located at the top/rear. The chip sensors are made of thin wires, which won't work if bent/damaged, and need to be replaced if this happens.
Please let me know if you have questions or there's anything else I can help you with.
Best regards~ Dana
