take it to honda - it's fail proof. i got stuck on the side of I495 for an hour cause my bro and his girl couldn't find the wheel lock key for the rim so we could change the flat. Oh well. Took it to honda and they took it off (had to break them all off cause they didn't have a master) and installed new ones. If you're looking to buy OEM parts from the Dealer....hmmmm $$$$.
