Lost my alloy wheels lock key!

[geek84]

Hi Folks

Please forgive me if this is the wrong forum to post my query

I have a fiesta flight 2002 which has alloy wheels. I now need to change one of the tyres. For that, I obviously need to unscrew the nuts on the alloy wheels. However, I cannot find the nut key. (The nut you use to open the other nuts around the alloy wheel).

How do I go about opening the nuts? If I do need to buy another key, how much do you thnk a new nut key will cost? Shall I look for one on ebay (which would hopefully be cheaper than going to my local Ford dealership?

Please advice

Thanks in advance.
