That really depends on your lugs. Without any key you'd most likely need to smash socket over the lock nuts with a hammer and then hope it is tight enough you can loosen them. The best thing to do would be to look into finding replacement adapter keys. It should be inexpensive and not much trouble if you know what brand the lug nuts are.
ohhh I see yeah I guess I just go back to where I got them from to see if they can sell me a replacement key thans so much really helpful
^ Wait are those ok to use on OEM wheels? I.e. are they safe?
if yes, then these are the same correct --> http://www.ebay.com/itm/Neon-Chrome-20-pcs-1-Key-12x1-5-MAG-Stock-Factory-OEM-Wheel-Lug-Nuts-A107-A01-/171348414144?pt=Motors_Car_Truck_Parts_Accessories&hash=item27e5294ec0&vxp=mtr
MOST aftermarket lugnuts are acorn/tapered so the SHOULD NOT be used with stock wheels. The stock/OEM lug nuts are mag seats with washers. It's very unlikely that you will find the correct OEM style lug nuts in Blue or Red.
